Drug Interaction Checker

Find out if your medicines are safe to take together.

  1. 1 Add each medicine you take: the brand on the box or the medicine inside it.
  2. 2 We check every pair, including each ingredient of combination medicines.
  3. 3 See what could happen and what to do, in plain language.

Serious interaction found

At least one pair of your medicines should not be taken together without a doctor's advice. Read the details below and talk to your doctor or pharmacist before your next dose.

Venclax Venetoclax Efavirenz

Major

Taking Venetoclax together with efavirenz should be avoided. Efavirenz is a moderate CYP3A inducer, which means it speeds up how the body breaks down Venetoclax, so the medicine may not work as well. The leaflet lists other medicines in the same group, but for efavirenz the advice is simply to avoid the combination.

What should I do?

These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.

What do Major, Moderate and Minor mean?
Major

The combination can cause serious harm or stop a medicine from working. Usually avoided, or only used with close medical supervision.

Moderate

The combination may need care: a different dose, taking them at different times, or extra check-ups.

Minor

Little or no effect is expected. Usually nothing needs to change.

Duplicate

Two of your medicines contain the same ingredient, which can add up to a double dose.
