Table 3: Dosage Modification for Renal Impairment Normal Dosage Regimen Creatinine Clearance (mL/min/1.73 m2) Adjusted Dosage Regimen Dose (mg) Dosing Interval 200 mg every 4 hours > 10 200 every 4 hours, 5x daily 0 to 10 200 every 12 hours 400 mg every 12 hours > 10 400 every 12 hours 0 to 10 200 every 12 hours 800 mg every 4 hours > 25 800 every 4 hours, 5x daily 10 to 25 800 every 8 hours 0 to 10 800 every 12 hours Hemodialysis
For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6 hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.
Peritoneal Dialysis
No supplemental dose appears to be necessary after adjustment of the dosing interval.
Bioequivalence of Dosage Forms
Acyclovir suspension was shown to be bioequivalent to acyclovir capsules (n = 20) and 1 acyclovir 800 mg tablet was shown to be bioequivalent to 4 acyclovir 200 mg capsules (n = 24).

Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.
Peritoneal Dialysis:
No supplemental dose appears to be necessary after adjustment of the dosing interval.
Method of Preparation:
Each 10 mL vial contains acyclovir sodium equivalent to 500 mg of acyclovir. The contents of the vial should be dissolved with 10 mL Sterile Water for Injection.
The resulting solution contains 50 mg acyclovir per mL. The pH of the solution is approximately 11. Shake the vial well to assure complete dissolution before measuring and transferring each individual dose. The reconstituted solution should be used within 12 hours. Refrigeration of reconstituted solution may result in the formation of a precipitate which will redissolve at room temperature.
DO NOT USE BACTERIOSTATIC WATER FOR INJECTION CONTAINING BENZYL ALCOHOL OR PARABENS.
Administration:
The calculated dose should be further diluted in an appropriate intravenous solution at a volume selected for administration during each 1 hour infusion. Infusion concentrations of approximately 7 mg/mL or lower are recommended. In clinical studies, the average 70 kg adult received between 60 and 150 mL of fluid per dose. Higher concentrations (e.g., 10 mg/mL) may produce phlebitis or inflammation at the injection site upon inadvertent extravasation. Standard, commercially available electrolyte and glucose solutions are suitable for intravenous administration; biologic or colloidal fluids (e.g., blood products, protein solutions, etc.) are not recommended.
Once diluted for administration, each dose should be used within 24 hours.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Higher concentrations (e.g., 10 mg/mL) may produce phlebitis or inflammation at the injection site upon inadvertent extravasation. Standard, commercially available electrolyte and glucose solutions are suitable for intravenous administration; biologic or colloidal fluids (e.g., blood products, protein solutions, etc.) are not recommended.
Once diluted for administration, each dose should be used within 24 hours.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Patients With Acute or Chronic Renal Impairment
In patients with renal impairment, the dose of acyclovir capsules and tablets should be modified as shown in Table 3:

For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6 hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.
Peritoneal Dialysis
No supplemental dose appears to be necessary after adjustment of the dosing interval.
Bioequivalence of Dosage Forms
Acyclovir suspension was shown to be bioequivalent to acyclovir capsules (n = 20) and 1 acyclovir 800 mg tablet was shown to be bioequivalent to 4 acyclovir 200 mg capsules (n = 24).

Swallow Duloxetine Delayed-Release Capsules USP whole. Do not chew or crush. Do not open the capsule and sprinkle its contents on food or mix with liquids. All of these might affect the enteric coating. Duloxetine Delayed-Release Capsules USP can be given without regard to meals. If a dose of Duloxetine Delayed-Release Capsules USP is missed, take the missed dose as soon as it is remembered. If it is almost time for the next dose, skip the missed dose and take the next dose at the regular time. Do not take two doses of Duloxetine Delayed-Release Capsules USP at the same time.
2.1 Dosage for Treatment of Major Depressive Disorder

Administer duloxetine at a total dose of 40 mg/day (given as 20 mg twice daily) to 60 mg/day (given either once daily or as 30 mg twice daily). For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. While a 120 mg/day dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer any additional benefits. The safety of doses above 120 mg/day has not been adequately evaluated. Periodically reassess to determine the need for maintenance treatment and the appropriate dose for such treatment [see Clinical Studies (14.1)].
2.2 Dosage for Treatment of Generalized Anxiety Disorder
Adults
For most patients, initiate duloxetine 60 mg once daily. For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to the medication before increasing to 60 mg once daily. While a 120 mg once daily dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer additional benefit. Nevertheless, if a decision is made to increase the dose beyond 60 mg once daily, increase dose in increments of 30 mg once daily. The safety of doses above 120 mg once daily has not been adequately evaluated. Periodically reassess to determine the continued need for maintenance treatment and the appropriate dose for such treatment [see Clinical Studies (14.2)].

Pediatric use information for patients ages 7 to 17 years is approved for Eli Lilly and Company, Inc.’s duloxetine delayed-release capsules. However, due to Eli Lilly and Company, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
2.3 Dosage for Treatment of Diabetic Peripheral Neuropathic Pain
Administer duloxetine 60 mg once daily. There is no evidence that doses higher than 60 mg confer additional significant benefit and the higher dose is clearly less well tolerated [see Clinical Studies (14.3)]. For patients for whom tolerability is a concern, a lower starting dose may be considered.

Since diabetes is frequently complicated by renal disease, consider a lower starting dose and gradual increase in dose for patients with renal impairment [see Dosage and Administration (2.6), Use in Specific Populations (8.10), and Clinical Pharmacology (12.3)].
2.5 Dosage for Treatment of Chronic Musculoskeletal Pain
Administer duloxetine 60 mg once daily. Begin treatment at 30 mg for one week, to allow patients to adjust to the medication before increasing to 60 mg once daily. There is no evidence that higher doses confer additional benefit, even in patients who do not respond to a 60 mg dose, and higher doses are associated with a higher rate of adverse reactions [see Clinical Studies (14.5)].
2.6 Dosing in Special Populations
Hepatic Impairment — Avoid use in patients with chronic liver disease or cirrhosis [see Warnings and Precautions (5.14)and Use in Specific Populations (8.9)].
Severe Renal Impairment — Avoid use in patients with severe renal impairment, GFR <30 mL/min [see Warnings and Precautions (5.14) and Use in Specific Populations (8.10)].
2.7 Discontinuing Duloxetine
Adverse reactions after discontinuation of duloxetine, after abrupt or tapered discontinuation, include: dizziness, headache, nausea, diarrhea, paresthesia, irritability, vomiting, insomnia, anxiety, hyperhidrosis, and fatigue. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [see Warnings and Precautions (5.7)].
2.8 Switching a Patient to or from a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders
At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with duloxetine. Conversely, at least 5 days should be allowed after stopping duloxetine before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4)].
2.9 Use of Duloxetine with Other MAOIs such as Linezolid or Methylene Blue
Do not start duloxetine in a patient who is being treated with linezolid or intravenous methylene blue because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered [see Contraindications (4)].

In some cases, a patient already receiving duloxetine therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, duloxetine should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for 5 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with duloxetine A may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.4)].

The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with duloxetine is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.4)].

For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6 hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.

No supplemental dose appears to be necessary after adjustment of the dosing interval.
Bioequivalence of Dosage Forms
Acyclovir suspension was shown to be bioequivalent to acyclovir capsules (n = 20) and 1 acyclovir 800 mg tablet was shown to be bioequivalent to 4 acyclovir 200 mg capsules (n = 24).

Hemodialysis
For patients who require dialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6 hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.
Peritoneal Dialysis
No supplemental dose appears to be necessary after adjustment of the dosing interval.
Method of Preparation
Each 10 mL vial contains acyclovir sodium equivalent to 500 mg of acyclovir. Each 20 mL vial contains acyclovir sodium equivalent to 1000 mg of acyclovir. The contents of the vial should be dissolved in Sterile Water for Injection as follows:
Contents of Vial
Amount of Diluent
500 mg
10 mL
1000 mg
20 mL
The resulting solution in each case contains 50 mg acyclovir per mL (pH approximately 11). Shake the vial well to assure complete dissolution before measuring and transferring each individual dose. The reconstituted solution should be used within 12 hours. Refrigeration of reconstituted solution may result in the formation of a precipitate which will redissolve at room temperature.
DO NOT USE BACTERIOSTATIC WATER FOR INJECTION CONTAINING BENZYL ALCOHOL OR PARABENS.
ADMINISTRATION
The calculated dose should then be removed and added to any appropriate intravenous solution at a volume selected for administration during each 1 hour infusion. Infusion concentrations of approximately 7 mg/mL or lower are recommended. In clinical studies, the average 70 kg adult received between 60 and 150 mL of fluid per dose. Higher concentrations (e.g., 10 mg/mL) may produce phlebitis or inflammation at the injection site upon inadvertent extravasation. Standard, commercially available electrolyte and glucose solutions are suitable for intravenous administration; biologic or colloidal fluids (e.g., blood products, protein solutions, etc.) are not recommended.
Once diluted for administration, each dose should be used within 24 hours.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

2.1 Usual Dosage and Administration
The usual dosage and frequency of administration of doxycycline differs from that of the other tetracyclines. Exceeding the recommended dosage may result in an increased incidence of side effects.
Adults
The usual dose of oral doxycycline is 200 mg on the first day of treatment (administered 100 mg every 12 hours), followed by a maintenance dose of 100 mg daily. The maintenance dose may be administered as a single dose or as 50 mg every 12 hours. In the management of more severe infections (particularly chronic infections of the urinary tract), 100 mg every 12 hours is recommended.
For Pediatric Patients Above 8 Years of Age
The recommended dosage schedule for children weighing 45 kg or less is 4.4 mg/kg of body weight divided into two doses on the first day of treatment, followed by 2.2 mg/kg of body weight given as a single daily dose or divided into two doses on subsequent days. For more severe infections up to 4.4 mg/kg of body weight may be used. For children over 45 kg, the usual adult dose should be used.
Administration of adequate amounts of fluid along with capsule and tablet forms of drugs in the tetracycline-class is recommended to wash down the drugs and reduce the risk of esophageal irritation and ulceration [see Adverse Reactions (6)].
If gastric irritation occurs, doxycycline may be given with food or milk [see Clinical Pharmacology (12)].
When used in streptococcal infections, therapy should be continued for 10 days.
Uncomplicated Urethral, Endocervical, or Rectal Infection Caused by Chlamydia Trachomatis
100 mg by mouth twice a day for 7 days. As an alternate dosing regimen for uncomplicated urethral or endocervical infection caused by Chlamydia trachomatis, administer 200 mg by mouth once a day for 7 days.
Uncomplicated Gonococcal Infections in Adults (Except Anorectal Infections in Men)
100 mg, by mouth, twice-a-day for 7 days. As an alternate single visit dose, administer 300 mg stat followed in one hour by a second 300 mg dose.
Nongonococcal Urethritis (NGU) Caused by U. Urealyticum
100 mg by mouth twice-a-day for 7 days.
Syphilis–Early
Patients who are allergic to penicillin should be treated with doxycycline 100 mg by mouth twice-a-day for 2 weeks.
Syphilis of More Than One Year’s Duration
Patients who are allergic to penicillin should be treated with doxycycline 100 mg by mouth twice-a-day for 4 weeks.
Acute Epididymo-Orchitis Caused by C. Trachomatis
100 mg, by mouth, twice-a-day for at least 10 days.
2.2 For Prophylaxis of Malaria
For adults, the recommended dose is 100 mg daily. For children over 8 years of age, the recommended dose is 2 mg/kg given once daily up to the adult dose. Prophylaxis should begin 1 or 2 days before travel to the malarious area. Prophylaxis should be continued daily during travel in the malarious area and for 4 weeks after the traveler leaves the malarious area.

weighing less than 45 kg, 2.2 mg/kg of body weight, by mouth, twice-a-day for 60 days. Children weighing 45 kg or more should receive the adult dose.
2.4 Sprinkling the Tablet over Applesauce
Doxycycline hyclate delayed-release tablets may also be administered by carefully breaking up the tablet and sprinkling the tablet contents (delayed-release beads) on a spoonful of applesauce. The delayed-release beads must not be crushed or damaged when breaking up the tablet. Any loss of beads in the transfer would prevent using the dose. The applesauce/doxycycline mixture should be swallowed immediately without chewing and may be followed by a glass of water if desired. The applesauce should not be hot, and it should be soft enough to be swallowed without chewing. In the event that a prepared dose of applesauce/doxycycline cannot be taken immediately, the mixture should be discarded and not stored for later use.

No supplemental dose appears to be necessary after adjustment of the dosing interval.

Acute Treatment of Herpes Zoster: 800 mg every 4 hours orally, 5 times daily for 7 to 10 days.
Genital Herpes: Treatment of Initial Genital Herpes: 200 mg every 4 hours, 5 times daily for 10 days.
Chronic Suppressive Therapy for Recurrent Disease: 400 mg 2 times daily for up to 12 months, followed by re-evaluation. Alternative regimens have included doses ranging from 200 mg 3 times daily to 200 mg 5 times daily.
The frequency and severity of episodes of untreated genital herpes may change over time. After 1 year of therapy, the frequency and severity of the patient’s genital herpes infection should be re-evaluated to assess the need for continuation of therapy with acyclovir tablets.
Intermittent Therapy: 200 mg every 4 hours, 5 times daily for 5 days. Therapy should be initiated at the earliest sign or symptom (prodrome) of recurrence.
Treatment of Chickenpox: Children (2 years of age and older): 20 mg/kg per dose orally 4 times daily (80 mg/kg/day) for 5 days. Children over 40 kg should receive the adult dose for chickenpox.
Adults and Children over 40 kg: 800 mg 4 times daily for 5 days.
Intravenous acyclovir is indicated for the treatment of varicella-zoster infections in immunocompromised patients.
When therapy is indicated, it should be initiated at the earliest sign or symptom of chickenpox. There is no information about the efficacy of therapy initiated more than 24 hours after onset of signs and symptoms.
Patients With Acute or Chronic Renal Impairment: In patients with renal impairment, the dose of acyclovir tablets should be modified as shown in Table 3.

Hemodialysis: For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6-hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.
Peritoneal Dialysis: No supplemental dose appears to be necessary after adjustment of the dosing interval.

2.1 Dosage in Adults
Use the lowest effective dose for the patient. The recommended initial dose is 5 mg for women and either 5 or 10 mg for men, taken only once per night immediately before bedtime with at least 7-8 hours remaining before the planned time of awakening. If the 5 mg dose is not effective, the dose can be increased to 10 mg. In some patients, the higher morning blood levels following use of the 10 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [see Warnings and Precautions (5.1)]. The total dose of zolpidem tartrate tablets should not exceed 10 mg once daily immediately before bedtime.
The recommended initial doses for women and men are different because zolpidem clearance is lower in women.
2.2 Special Populations
Elderly or debilitated patients may be especially sensitive to the effects of zolpidem tartrate. Patients with hepatic insufficiency do not clear the drug as rapidly as normal subjects. The recommended dose of zolpidem tartrate in both of these patient populations is 5 mg once daily immediately before bedtime [see Warnings and Precautions (5.1); Use in Specific Populations (8.5)].
2.3 Use with CNS Depressants
Dosage adjustment may be necessary when zolpidem tartrate tablets are combined with other CNS depressant drugs because of the potentially additive effects [see Warnings and Precautions (5.1)].
2.4 Administration
The effect of zolpidem tartrate tablets may be slowed by ingestion with or immediately after a meal.
