Questions & Answers
Side Effects & Adverse Reactions
General: Considerable caution should be exercised in patients with hypertension, diabetes mellitus,
ischemic heart disease, hyperthyroidism, increased intraocular pressure, and prostatic hypertrophy.
The elderly (60 years and older) are more likely to exhibit adverse reactions.
Usage in Ambulatory Patients: Dihydrocodeine may impair the mental and/or physical abilities
required for the performance of potentially hazardous tasks such as driving a car or operating
machinery.
Respiratory Depression: Respiratory depression is the most dangerous acute reaction produced by
opioid agonist preparations, although it is rarely severe with usual doses. Opioids decrease the
respiratory tidal volume, minute ventilation, and sensitivity to carbon dioxide. Respiratory depression
occurs most frequently in elderly or debilitated patients, usually after large initial doses in
non-tolerant patients, or when opioids are given in conjunction with other agents that depress
respiration. This combination product should be used with caution in patients with significant chronic
obstructive pulmonary disease or cor pulmonale and in patients with a substantially decreased
respiratory reserve, hypoxia, hypercapnia, or respiratory depression.
Hypertensive Effect: Dihydrocodeine, like all opioid analgesics, may cause hypotension in patients
whose ability to maintain blood pressure has been compromised by a depleted blood volume or who
received concurrent therapy with drugs such as phenothiazine or other agents which compromise
vasomotor tone. This product may produce orthostatic hypotension in ambulatory patients. This
combination product should be administered with caution to patients with circulatory shock since
vasodilation produced by the drug may further reduce cardiac output and blood pressure.
Dependence: Dihydrocodeine can produce drug dependence of the codeine type and has the
potential of being abused. This product should be prescribed and administered with the appropriate
degree of caution (See
Drug Abuse and Dependence section).
