Interactions between your drugs

Moderate

codeine attapulgite

Applies to: codeine / phenylephrine, Kaopek (attapulgite)

MONITOR: Coadministration of narcotic analgesics with antidiarrheal agents may have additive central nervous system (CNS) and gastrointestinal (GI) system effects, and increase the risk of severe constipation or paralytic ileus and CNS depression.

MANAGEMENT: If concomitant use cannot be avoided, patients should be monitored for potentially excessive or prolonged CNS depression and constipation. Ambulatory patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

Drug and food interactions

Moderate

codeine food

Applies to: codeine / phenylephrine

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

Moderate

phenylephrine food

Applies to: codeine / phenylephrine

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
