Cautions with other medicines
Other medicines are unlikely to affect the way benzydamine works. However, it's a good idea to tell your doctor, dentist or pharmacist about all the medicines you're taking.
Mixing benzydamine with herbal remedies and supplements
There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to use with benzydamine. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
