What are the risks of taking over-the-counter medicines?

Just like any other medicines, OTC medicines can cause side effects. For example, there are some over-the-counter pain medicines you shouldn't use if you have other health conditions.

Talk to the pharmacist first if you have stomach, kidney, liver or heart problems, or are pregnant.

Some over-the-counter medicines and alternative medicines can interact with medicines prescribed by your doctor. Interactions may stop your medicines from working as expected.

If you take a combination of medicines, including OTC medicines, you may be more likely to have side effects.

Always let your doctor or pharmacist know what prescription, over-the-counter and alternative or complementary medicines you are taking.

OTC medicines sold in Australia are checked for safety by the Therapeutic Goods Administration.
