Proper Use of Lorazepam Oral Concentrate USP:
Lorazepam Oral Concentrate is a concentrated oral solution as compared to standard oral liquid medications. It is recommended that Lorazepam Oral Concentrate be mixed with liquid or semi-solid food such as water, juices, soda or soda-like beverages, applesauce and puddings.
Use only the calibrated dropper provided with this product. Draw into the dropper the amount prescribed for a single dose. Then squeeze the dropper contents into a liquid or semi-solid food. Stir the liquid or food gently for a few seconds. The Lorazepam Oral Concentrate formulation blends quickly and completely. The entire amount of the mixture, of drug and liquid or drug and food, should be consumed immediately. Do not store for future use.
Lorazepam is administered orally. For optimal results, dose, frequency of administration, and duration of therapy should be individualized according to patient response.
The usual range is 2 mg/day to 6 mg/day given in divided doses, the largest dose being taken before bedtime, but the daily dosage may vary from 1 mg/day to 10 mg/day.
For anxiety, most patients require an initial dose of 2 mg/day to 3 mg/day given b.i.d. or t.i.d.
For insomnia due to anxiety or transient situational stress, a single daily dose of 2 mg to 4 mg may be given, usually at bedtime.
For elderly or debilitated patients, an initial dosage of 1 mg/day to 2 mg/day in divided doses is recommended, to be adjusted as needed and tolerated.
The dosage of lorazepam should be increased gradually when needed to help avoid adverse effects. When higher dosage is indicated, the evening dose should be increased before the daytime doses.
For the treatment of chronic eczematous external otitis, using the supplied ear-dropper, apply 5 drops of fluocinolone acetonide oil 0.01% into the affected ear. To apply, tilt head to one side so that the ear is facing up. Then gently pull the ear lobe backward and upward and apply 5 drops of fluocinolone acetonide oil 0.01% into the ear. Keep head tilted for about a minute to allow fluocinolone acetonide oil 0.01% to penetrate lower into the ear canal. Gently pat excess material dripping out of the ear using a clean cotton ball. Follow these instructions twice each day for 7 to 14 days.
Fluocinolone Acetonide Oil
Fluocinolone acetonide 0.01% topical oil is not for oral, ophthalmic, or intravaginal use.
The dosing of fluocinolone acetonide 0.01% topical oil is different for adult and pediatric patients.
2.1 Adult Patients with Atopic Dermatitis
Apply fluocinolone acetonide 0.01% topical oil as a thin film to the affected areas three times daily.
2.2 Pediatric Patients with Atopic Dermatitis
Moisten skin and apply fluocinolone acetonide 0.01% topical oil as a thin film to the affected areas twice daily for up to four weeks.
Fluocinolone Acetonide Oil
Fluocinolone Acetonide 0.01% Topical Oil for scalp psoriasis in adults (Scalp Oil):
For the treatment of scalp psoriasis, wet or dampen hair and scalp thoroughly. Apply a thin film of Fluocinolone Acetonide 0.01% Topical Oil on the scalp, massage well and cover scalp with the supplied shower cap. Leave on overnight, or for a minimum of 4 hours before washing off. Wash hair with regular shampoo and rinse thoroughly.
As a dietary adjunct before, during and after pregnancy, take one tablet daily with a meal, or as directed by a physician.
Esterified Estrogens And Methyltestosterone
When estrogen is prescribed for a postmenopausal woman with a uterus, a progestin should also be initiated to reduce the risk of endometrial cancer.
A woman without a uterus does not need progestin. Use of estrogen, alone or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Patients should be reevaluated periodically as clinically appropriate (e.g., 3-month to 6-month intervals) to determine if treatment is still necessary. (See BOXED WARNINGS and WARNINGS.) For women who have a uterus, adequate diagnostic measures, such as endometrial sampling, when indicated, should be undertaken to rule out malignancy in cases of undiagnosed persistent or recurring abnormal vaginal bleeding.
Given cyclically for short-term use only:
For treatment of moderate to severe vasomotor symptoms associated with the menopause in patients not improved by estrogen alone.
The lowest dose that will control symptoms should be chosen and medication should be discontinued as promptly as possible.
Administration should be cyclic (e.g., three weeks on and one week off). Attempts to discontinue or taper medication should be made at three- to six month intervals.
Usual Dosage Range:
1 tablet of Esterified Estrogens and Methyltestosterone Tablets or 1 to 2 tablets of Esterified Estrogens and Methyltestosterone Tablets H.S. daily as recommended by the physician.
Treated patients with an intact uterus should be monitored closely for signs of endometrial cancer and appropriate diagnostic measures should be taken to rule out malignancy in the event of persistent or recurring abnormal vaginal bleeding.
The recommended dose for adults and children over 12 years of age is one 800 mg tablet three to four times a day.
2.1 Individualized Dosing
The dosage and administration of warfarin sodium tablets, USP must be individualized for each patient according to the patient’s INR response to the drug. Adjust the dose based on the patient’s INR and the condition being treated. Consult the latest evidence-based clinical practice guidelines from the American College of Chest Physicians (ACCP) to assist in the determination of the duration and intensity of anticoagulation with warfarin sodium tablets, USP [see References (15)].
2.2 Recommended Target INR Ranges and Durations for Individual Indications
An INR of greater than 4.0 appears to provide no additional therapeutic benefit in most patients and is associated with a higher risk of bleeding.
Venous Thromboembolism (including deep venous thrombosis [DVT] and PE)
Adjust the warfarin dose to maintain a target INR of 2.5 (INR range, 2.0 to 3.0) for all treatment durations. The duration of treatment is based on the indication as follows:For patients with a DVT or PE secondary to a transient (reversible) risk factor, treatment with warfarin for 3 months is recommended. For patients with an unprovoked DVT or PE, treatment with warfarin is recommended for at least 3 months. After 3 months of therapy, evaluate the risk-benefit ratio of long-term treatment for the individual patient. For patients with two episodes of unprovoked DVT or PE, long-term treatment with warfarin is recommended. For a patient receiving long-term anticoagulant treatment, periodically reassess the risk-benefit ratio of continuing such treatment in the individual patient.
In patients with non-valvular AF, anticoagulate with warfarin to target INR of 2.5 (range, 2.0 to 3.0).In patients with non-valvular AF that is persistent or paroxysmal and at high risk of stroke (i.e., having any of the following features: prior ischemic stroke, transient ischemic attack, or systemic embolism, or 2 of the following risk factors: age greater than 75 years, moderately or severely impaired left ventricular systolic function and/or heart failure, history of hypertension, or diabetes mellitus), long-term anticoagulation with warfarin is recommended. In patients with non-valvular AF that is persistent or paroxysmal and at an intermediate risk of ischemic stroke (i.e., having 1 of the following risk factors: age greater than 75 years, moderately or severely impaired left ventricular systolic function and/or heart failure, history of hypertension, or diabetes mellitus), long-term anticoagulation with warfarin is recommended. For patients with AF and mitral stenosis, long-term anticoagulation with warfarin is recommended. For patients with AF and prosthetic heart valves, long-term anticoagulation with warfarin is recommended; the target INR may be increased and aspirin added depending on valve type and position, and on patient factors.
Mechanical and Bioprosthetic Heart ValvesFor patients with a bileaflet mechanical valve or a Medtronic Hall (Minneapolis, MN) tilting disk valve in the aortic position who are in sinus rhythm and without left atrial enlargement, therapy with warfarin to a target INR of 2.5 (range, 2.0 to 3.0) is recommended. For patients with tilting disk valves and bileaflet mechanical valves in the mitral position, therapy with warfarin to a target INR of 3.0 (range, 2.5 to 3.5) is recommended. For patients with caged ball or caged disk valves, therapy with warfarin to a target INR of 3.0 (range, 2.5 to 3.5) is recommended. For patients with a bioprosthetic valve in the mitral position, therapy with warfarin to a target INR of 2.5 (range, 2.0 to 3.0) for the first 3 months after valve insertion is recommended. If additional risk factors for thromboembolism are present (AF, previous thromboembolism, left ventricular dysfunction), a target INR of 2.5 (range, 2.0 to 3.0) is recommended.
Post-Myocardial InfarctionFor high-risk patients with MI (e.g., those with a large anterior MI, those with significant heart failure, those with intracardiac thrombus visible on transthoracic echocardiography, those with AF, and those with a history of a thromboembolic event), therapy with combined moderate-intensity (INR, 2.0 to 3.0) warfarin plus low-dose aspirin (≤100 mg/day) for at least 3 months after the MI is recommended.
Recurrent Systemic Embolism and Other Indications
Oral anticoagulation therapy with warfarin has not been fully evaluated by clinical trials in patients with valvular disease associated with AF, patients with mitral stenosis, and patients with recurrent systemic embolism of unknown etiology. However, a moderate dose regimen (INR 2.0 to 3.0) may be used for these patients.
2.3 Initial and Maintenance Dosing
The appropriate initial dosing of warfarin sodium tablets, USP varies widely for different patients. Not all factors responsible for warfarin dose variability are known, and the initial dose is influenced by:Clinical factors including age, race, body weight, sex, concomitant medications, and comorbidities Genetic factors (CYP2C9 and VKORC1 genotypes) [see Clinical Pharmacology (12.5)]
Select the initial dose based on the expected maintenance dose, taking into account the above factors. Modify this dose based on consideration of patient-specific clinical factors. Consider lower initial and maintenance doses for elderly and/or debilitated patients and in Asian patients [see Use in Specific Populations (8.5) and Clinical Pharmacology (12.3)]. Routine use of loading doses is not recommended as this practice may increase hemorrhagic and other complications and does not offer more rapid protection against clot formation.
Individualize the duration of therapy for each patient. In general, anticoagulant therapy should be continued until the danger of thrombosis and embolism has passed [see Dosage and Administration (2.2)].
Dosing Recommendations without Consideration of Genotype
If the patient’s CYP2C9 and VKORC1 genotypes are not known, the initial dose of warfarin sodium tablets, USP is usually 2 to 5 mg once daily. Determine each patient’s dosing needs by close monitoring of the INR response and consideration of the indication being treated. Typical maintenance doses are 2 to 10 mg once daily.
Dosing Recommendations with Consideration of Genotype
Table 1 displays three ranges of expected maintenance warfarin sodium tablets, USP doses observed in subgroups of patients having different combinations of CYP2C9 and VKORC1 gene variants [see Clinical Pharmacology (12.5)]. If the patient’s CYP2C9 and/or VKORC1 genotype are known, consider these ranges in choosing the initial dose. Patients with CYP2C9 *1/*3, *2/*2, *2/*3, and *3/*3 may require more prolonged time (>2 to 4 weeks) to achieve maximum INR effect for a given dosage regimen than patients without these CYP variants.Table 1: Three Ranges of Expected Maintenance Warfarin Sodium Tablets, USP Daily Doses Based on CYP2C9 and VKORC1 Genotypes† VKORC1 CYP2C9 †Ranges are derived from multiple published clinical studies. VKORC1 -1639G>A (rs9923231) variant is used in this table. Other co-inherited VKORC1 variants may also be important determinants of warfarin dose. *1/*1 *1/*2 *1/*3 *2/*2 *2/*3 *3/*3 GG 5 to 7 mg 5 to 7 mg 3 to 4 mg 3 to 4 mg 3 to 4 mg 0.5 to 2 mg AG 5 to 7 mg 3 to 4 mg 3 to 4 mg 3 to 4 mg 0.5 to 2 mg 0.5 to 2 mg AA 3 to 4 mg 3 to 4 mg 0.5 to 2 mg 0.5 to 2 mg 0.5 to 2 mg 0.5 to 2 mg
2.4 Monitoring to Achieve Optimal Anticoagulation
Warfarin sodium tablets, USP are a narrow therapeutic range (index) drug, and its action may be affected by factors such as other drugs and dietary vitamin K. Therefore, anticoagulation must be carefully monitored during warfarin sodium tablets, USP therapy. Determine the INR daily after the administration of the initial dose until INR results stabilize in the therapeutic range. After stabilization, maintain dosing within the therapeutic range by performing periodic INRs. The frequency of performing INR should be based on the clinical situation but generally acceptable intervals for INR determinations are 1 to 4 weeks. Perform additional INR tests when other warfarin products are interchanged with warfarin sodium tablets, USP, as well as whenever other medications are initiated, discontinued, or taken irregularly. Heparin, a common concomitant drug, increases the INR [see Dosage and Administration (2.8) and Drug Interactions (7)].
Determinations of whole blood clotting and bleeding times are not effective measures for monitoring of warfarin sodium tablets, USP therapy.
2.5 Missed Dose
The anticoagulant effect of warfarin sodium tablets, USP persists beyond 24 hours. If a patient misses a dose of warfarin sodium tablets, USP at the intended time of day, the patient should take the dose as soon as possible on the same day. The patient should not double the dose the next day to make up for a missed dose.
2.7 Treatment During Dentistry and Surgery
Some dental or surgical procedures may necessitate the interruption or change in the dose of warfarin sodium tablets, USP therapy. Consider the benefits and risks when discontinuing warfarin sodium tablets, USP even for a short period of time. Determine the INR immediately prior to any dental or surgical procedure. In patients undergoing minimally invasive procedures who must be anticoagulated prior to, during, or immediately following these procedures, adjusting the dosage of warfarin sodium tablets, USP to maintain the INR at the low end of the therapeutic range may safely allow for continued anticoagulation.
2.8 Conversion From Other Anticoagulants
Since the full anticoagulant effect of warfarin sodium tablets, USP is not achieved for several days, heparin is preferred for initial rapid anticoagulation. During initial therapy with warfarin sodium tablets, USP, the interference with heparin anticoagulation is of minimal clinical significance. Conversion to warfarin sodium tablets, USP may begin concomitantly with heparin therapy or may be delayed 3 to 6 days. To ensure therapeutic anticoagulation, continue full dose heparin therapy and overlap warfarin sodium tablets, USP therapy with heparin for 4 to 5 days and until warfarin sodium tablets, USP has produced the desired therapeutic response as determined by INR, at which point heparin may be discontinued.
As heparin may affect the INR, patients receiving both heparin and warfarin sodium tablets, USP should have INR monitoring at least:5 hours after the last intravenous bolus dose of heparin, or 4 hours after cessation of a continuous intravenous infusion of heparin, or 24 hours after the last subcutaneous heparin injection.
Warfarin sodium tablets, USP may increase the activated partial thromboplastin time (aPTT) test, even in the absence of heparin. A severe elevation (>50 seconds) in aPTT with an INR in the desired range has been identified as an indication of increased risk of postoperative hemorrhage.
Consult the labeling of other anticoagulants for instructions on conversion to warfarin sodium tablets, USP.
The initial dose of 25 mg to 50 mg of meclizine HCl tablets, USP should be taken one hour prior to travel for protection against motion sickness. Thereafter, the dose may be repeated every 24 hours for the duration of the journey.
Esomeprazole strontium is supplied as delayed-release capsules for oral administration. The recommended dosages are outlined in Table 1. Esomeprazole strontium should be taken at least one hour before meals.
The duration of proton pump inhibitor administration should be based on available safety and efficacy data specific to the defined indication and dosing frequency, as described in the prescribing information, and individual patient medical needs. Proton pump inhibitor treatment should only be initiated and continued if the benefits outweigh the risks of treatment.Table 1: Recommended Dosage Schedule of Esomeprazole Strontium Delayed-Release Capsules

For patients with severe liver impairment (Child Pugh Class C), a dose of 24.65 mg of esomeprazole strontium (equivalent to 20 mg of esomeprazole) should not be exceeded [see Clinical Pharmacology (12.3)].
Directions for use specific to the route and available methods of administration are presented in Table 2.Table 2: Administration Options
Administration Options(See text following table for additional instructions.)
Capsule can be swallowed whole. Do not chew or crush; or
Capsule can be opened and granules mixed with applesauce. Do not chew or crush granules.
Capsule can be opened and the intact granules emptied into a catheter tipped syringe and delivered through the nasogastric tube.
Esomeprazole strontium delayed-release capsules should be swallowed whole. Do not chew or crush capsule.
Alternatively, for patients who have difficulty swallowing capsules, one tablespoon of applesauce can be added to an empty bowl and the esomeprazole strontium delayed-release capsule can be opened, and the granules inside the capsule carefully emptied onto the applesauce. The granules should be mixed with the applesauce and then swallowed immediately: do not store for future use. The applesauce used should not be hot and should be soft enough to be swallowed without chewing. The granules should not be chewed or crushed. If the granules/applesauce mixture is not used in its entirety, the remaining mixture should be discarded immediately.
For patients who have a nasogastric tube in place, esomeprazole strontium delayed-release capsules can be opened and the intact granules emptied into a 60 mL catheter tipped syringe and mixed with 50 mL of water. It is important to only use a catheter tipped syringe when administering esomeprazole strontium delayed-release capsules through a nasogastric tube. Replace the plunger and shake the syringe vigorously for 15 seconds. Hold the syringe with the tip up and check for granules remaining in the tip. Attach the syringe to a nasogastric tube and deliver the contents of the syringe through the nasogastric tube into the stomach. After administering the granules, the nasogastric tube should be flushed with additional water. Do not administer the granules if they have dissolved or disintegrated.
The mixture must be used immediately after preparation.
Alprazolam extended-release tablets may be administered once daily, preferably in the morning. The tablets should be taken intact; they should not be chewed, crushed, or broken.
The suggested total daily dose ranges between 3 to 6 mg/day. Dosage should be individualized for maximum beneficial effect. While the suggested total daily dosages given will meet the needs of most patients, there will be some patients who require doses greater than 6 mg/day. In such cases, dosage should be increased cautiously to avoid adverse effects.
Dosing in Special Populations
In elderly patients, in patients with advanced liver disease, or in patients with debilitating disease, the usual starting dose of alprazolam extended-release tablets is 0.5 mg once daily. This may be gradually increased if needed and tolerated (see Dose Titration).The elderly may be especially sensitive to the effects of benzodiazepines.
Treatment with alprazolam extended-release tablets may be initiated with a dose of 0.5 mg to 1 mg once daily. Depending on the response, the dose may be increased at intervals of 3 to 4 days in increments of no more than 1 mg/day. Slower titration to the dose levels may be advisable to allow full expression of the pharmacodynamic effect of alprazolam extended-release tablets.
Generally, therapy should be initiated at a low dose to minimize the risk of adverse responses in patients especially sensitive to the drug. Dose should be advanced until an acceptable therapeutic response (i.e., a substantial reduction in or total elimination of panic attacks) is achieved, intolerance occurs, or the maximum recommended dose is attained.
In controlled trials conducted to establish the efficacy of alprazolam extended-release tablets in panic disorder, doses in the range of 1 to 10 mg/day were used. Most patients showed efficacy in the dose range of 3 to 6 mg/day. Occasional patients required as much as 10 mg/day to achieve a successful response.
The necessary duration of treatment for panic disorder patients responding to alprazolam extended-release tablets is unknown. However, periodic reassessment is advised. After a period of extended freedom from attacks, a carefully supervised tapered discontinuation may be attempted, but there is evidence that this may often be difficult to accomplish without recurrence of symptoms and/or the manifestation of withdrawal phenomena.
Because of the danger of withdrawal, abrupt discontinuation of treatment should be avoided (see WARNINGS, PRECAUTIONS, DRUG ABUSE AND DEPENDENCE).
In all patients, dosage should be reduced gradually when discontinuing therapy or when decreasing the daily dosage. Although there are no systematically collected data to support a specific discontinuation schedule, it is suggested that the daily dosage be decreased by no more than 0.5 mg every three days. Some patients may require an even slower dosage reduction.
In any case, reduction of dose must be undertaken under close supervision and must be gradual. If significant withdrawal symptoms develop, the previous dosing schedule should be reinstituted and, only after stabilization, should a less rapid schedule of discontinuation be attempted. In a controlled postmarketing discontinuation study of panic disorder patients which compared this recommended taper schedule with a slower taper schedule, no difference was observed between the groups in the proportion of patients who tapered to zero dose; however, the slower schedule was associated with a reduction in symptoms associated with a withdrawal syndrome. It is suggested that the dose be reduced by no more than 0.5 mg every three days, with the understanding that some patients may benefit from an even more gradual discontinuation. Some patients may prove resistant to all discontinuation regimens.
Switch from Alprazolam Immediate-Release Tablets to Alprazolam Extended-Release Tablets
Patients who are currently being treated with divided doses of alprazolam (immediate-release) tablets, for example 3 to 4 times a day, may be switched to alprazolam extended-release tablets at the same total daily dose taken once daily. If the therapeutic response after switching is inadequate, the dosage may be titrated as outlined above.
Hydrocodone Bitartrate And Acetaminophen
Dosage should be adjusted according to the severity of the pain and the response of the patient. However, it should be kept in mind that tolerance to hydrocodone can develop with continued use and that the incidence of untoward effects is dose related.
The usual adult dosage is one tablet every four to six hours as needed for pain. The total daily dose should not exceed 5 tablets.
Oxycodone And Acetaminophen
Dosage should be adjusted according to the severity of the pain and the response of the patient. It may occasionally be necessary to exceed the usual dosage recommended below in cases of more severe pain or in those patients who have become tolerant to the analgesic effect of opioids.
If pain is constant, the opioid analgesic should be given at regular intervals on an around-the-clock schedule. Oxycodone and acetaminophen tablets are given orally.
The usual adult dosage is one tablet every 6 hours as needed for pain. The total daily dose of acetaminophen should not exceed 4 grams.
Strength Maximal Daily Dose
Oxycodone and Acetaminophen Tablets 7.5 mg / 500 mg 8 Tablets
Oxycodone and Acetaminophen Tablets 10 mg / 650 mg 6 Tablets
Cessation of Therapy
In patients treated with oxycodone and acetaminophen tablets for more than a few weeks who no longer require therapy, doses should be tapered gradually to prevent signs and symptoms of withdrawal in the physically dependent patient.
