Is dry mouth or dry lips a common side effect of isotretinoin?

Yes, dry mouth and dry lips are very common side effects of isotretinoin. The medicine reduces oil glands, which makes the skin and lips dry. Keep your lips moisturised and drink plenty of water while taking it.

I have had acne vulgaris and acne marks on my face for many years. I read that salicylic acid peels help with acne marks, but the treatment is too expensive for me as a student. I am currently taking isotretinoin. Can I use SESDERMA Azelac lotion as a cheaper option to reduce acne marks, and is it safe?

Acne marks often take time to fade, even after the acne is controlled. While lotions containing azelaic acid may help reduce pigmentation and improve skin texture, your skin may be more sensitive because you are taking isotretinoin. Using additional active products without guidance may cause irritation. Consult your doctor before using any new lotion as part of your treatment.

experiencing congestion in my nose every night. For the past five months, I have been taking 20 mg of isotretinion. My nose became dry from the inside out.

Isotretinoin frequently results in dryness inside the nose, which can cause irritation, crusting, moderate bleeding, and congestion at night. This occurs as a result of the medication's reduction of moisture and oil in the nasal lining. The dryness may be relieved by using a saline nasal spray, inhaling steam, drinking plenty of water, and putting a tiny bit of saline gel or simple petroleum jelly inside the nostrils. Don't use decongestant nasal sprays excessively. It is best to go to your dermatologist or ENT physician about this since you have been experiencing symptoms for five months. The dose may need to be changed, and the nose may need to be examined.
