Warnings and precautions
Acne often looks worse for the first two to four weeks before it improves. This is expected — do not stop. Use sunscreen every day. These medicines make the skin burn much more easily. Oral isotretinoin must never be taken in pregnancy — it causes severe birth defects. Reliable contraception and the pregnancy tests your dermatologist requires are essential before, during and after the course. Start with alternate nights and build up, and do not use more than a pea-sized amount for the whole face. Do not combine several strong acne actives at once without advice — the irritation compounds.
Do not take Isac if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Oral retinoids are absolutely contraindicated in pregnancy and in anyone who might become pregnant without a pregnancy prevention programme. Topical retinoids are avoided in pregnancy.
Interactions with other medicines
Do not combine with other peeling agents or with waxing and harsh scrubs. Oral retinoids must not be combined with tetracycline antibiotics.
How to store Isac 20 mg Capsule
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Expert advice for Isac 20 mg Capsule
Apply retinoids at night to clean, dry skin, and moisturise afterwards. Give it at least eight to twelve weeks before judging whether it works. Do not pick or squeeze spots — that is what leaves scars.
