Cautions with other medicines
Some products and medicines can irritate your skin if you use them while you're treating your skin with benzoyl peroxide gel or wash.
Do not use benzoyl peroxide with any other medicines that may have drying or irritating effects on your skin. These include alcohol-based skincare products. Always check the ingredients on the label and choose products for sensitive skin.
Do not use other benzoyl peroxide products or other acne medicines (such as isotretinoin), unless your doctor or pharmacist says it's OK. It may cause your skin to become very sore.
Mixing benzoyl peroxide with herbal remedies and supplements
There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with benzoyl peroxide. 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.
