Hi, Thanks for posting in HCM. I understand your concern. Acutret Capsule contains Isotretinoin as an active ingredient. It works by decreasing the amount of oil secreted by oil glands and is used to treat severe acne. Common side effects with its use include: Changes in skin color, Skin peeling, Cracking of skin, Cracked lips, Dry lips, Dry skin, Bleeding gums, Impaired healing, Increased sweating, Nose bleed, Sore throat, Hoarseness of voice, Abnormal hair growth on a women face and body.
