How can this medicine affect other medicines?

It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.

If isotretinoin is used in combination with tetracycline-type antibiotics, eg minocycline, doxycycline, tetracycline, this may increase the pressure within the skull, leading to adverse effects. For this reason, tetracycline antibiotics must not be taken in combination with isotretinoin.

Combined treatment with isotretinoin and vitamin A may result in a condition similar to vitamin A overdose, which may cause changes in the structure of the bone. Vitamin A supplements should therefore be avoided.

The use of other treatments conventionally used for acne, including antibiotics, exfoliants, medicines which loosen the dead skin on the skin surface (keratolytics), or radiation therapy with ultraviolet light, should be avoided while taking isotretinoin. However, non-irritant preparations can be applied to the skin if necessary.
