Carbamazepine Oral Suspension <> Valium
Relevance: 23.05.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Using carBAMazepine and diazePAM together may alter the effectiveness of diazePAM. If you take both medications together, tell your doctor if diazePAM is not effective. You may need a dose adjustment if you take both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

MONITOR: Some antiepileptic agents such as carbamazepine and phenytoin significantly reduce the effect of oral midazolam. The mechanism may be due to enhanced gut and liver metabolism of midazolam (via CYP450 3A4 enzyme induction by carbamazepine). Parenteral midazolam is not likely to be affected. Other oral benzodiazepines metabolized by the 3A4 isoenzyme may interact similarly.

MANAGEMENT: Patients receiving this combination should be monitored for clinical response. Alternative oral sedative hypnotics may be preferable in patients receiving carbamazepine.
