When to ask a pharmacist about your medicines

Pharmacists can help clarify directions, duplicate ingredients, interactions, side effects, storage and medicine reviews.

Taking more than one medicine can make timing, side effects and interactions harder to understand. Pharmacists can help you organise questions and identify issues that need the prescriber's input.

Ask before adding something new

Check before starting a new non-prescription medicine, vitamin, supplement or herbal product. Bring the packaging or a clear photo of the ingredients and share your complete medicine list.

Ask when the schedule is difficult

  • Which medicines must be taken at a particular time or with food?
  • What should I do if I miss a dose?
  • Could any products contain the same active ingredient?
  • Which side effects should I monitor and which need urgent help?
  • How should each medicine be stored and disposed of?

Ask for a medicine review

A structured review can help when you take several medicines, have side effects, have recently left hospital or are unsure why a medicine is still needed. Do not stop or change doses before speaking with the appropriate healthcare professional.

Use Ask a Pharmacist for non-emergency medicine questions. Do not upload more personal or medical information than the pharmacist needs to answer safely.

Frequently asked questions

Can supplements interact with medicines?

Yes, some supplements and herbal products can affect prescribed medicines. Include them on your medicine list and check before starting something new.

Should I change a dose if I have side effects?

Do not change or stop a prescribed medicine on your own. Ask a pharmacist, prescriber or urgent-care service depending on how severe the symptoms are.
