What drugs interact with Klonopin and Valium?
Klonopin drug interactions
Klonopin, like all other benzodiazepines, accentuates the effects of other drugs that slow the brain’s processes — such as alcohol, barbiturates, and narcotics, leading to increased sedation.
Valium drug interactions
Alcohol or medications that cause sedation may add to the sedative effects of Valium. Patients taking benzodiazepines should avoid such combinations.
The following drugs may prolong the effects of Valium by inhibiting liver enzymes that eliminate diazepam:
Dosages may need to be decreased when these drugs are used with Valium.
Carbamazepine (Tegretol), rifampin (Rifadin), and St. John’s Wort decrease levels of Valium by increasing the elimination of diazepam by liver enzymes.
