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.

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.

Important: This checker lists interactions found in medicine leaflets and may not be complete. It does not know your dose, your health conditions, or food and supplement interactions. Never start, stop or change a medicine because of this tool alone: ask a registered doctor or pharmacist.
