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.

The same medicine appears twice

Two of your medicines contain the same ingredient, so taking both could mean a double dose. See the details below.

1 Moderate 1 duplicate 1 pair checked

Diphenhydramine + Dextromethorphan + Levomenthol and Dextromethorphan Hydrobromide contain the same medicine

Double dose risk

Both contain Dextromethorphan. Taking them together could mean a double dose. Do not take both unless your doctor or pharmacist has said it is OK.

1 interaction

Diphenhydramine + Dextromethorphan + Levomenthol Dextromethorphan Hydrobromide

Moderate

Taking Dextromethorphan Hydrobromide with MAO inhibitors can sometimes cause very high fever, hallucinations, extreme excitement or coma.

What should I do?

These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.

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.
