What should I do if my lips are dry after taking isotretinoin soft capsules?
Taking isotretinoin soft capsules may cause dry lips, which could be related to drug side effects, insufficient water intake, food irritation, environmental factors, or cheilitis. Management options include discontinuing the medication, increasing fluid intake, eating a bland diet, using a humidifier, and applying appropriate medications. It is recommended to visit a hospital to determine the exact cause and follow medical advice for treatment. The details are as follows:

1. Drug side effects: Isotretinoin soft capsules are commonly used in dermatology, primarily for treating moderate to severe nodular acne. During treatment, the drug may exert certain irritative effects on the body, leading to adverse reactions in some individuals, such as dry skin, chapped lips, and flaking. If dry lips are confirmed to be caused by isotretinoin after consultation with a doctor, consideration can be given to stopping the medication or adjusting the dosage.
2. Insufficient water intake: Inadequate fluid consumption during isotretinoin therapy may lead to dehydration, thereby worsening lip dryness. Maintaining sufficient hydration can help alleviate this symptom. It is recommended to drink adequate amounts of water daily and avoid prolonged periods without drinking.
3. Food irritation: After taking isotretinoin, consuming spicy, greasy, or irritating foods without dietary caution may further irritate the lips and increase dryness. It is advisable to avoid such foods to prevent exacerbation of symptoms. Instead, opt for mild and easily digestible foods such as vegetables and fruits.
4. Environmental factors: Remaining in dry, cold, or windy environments for extended periods after taking the medication may also contribute to dry lips. Using a humidifier indoors can increase air moisture and help relieve dryness. However, it is important to clean the humidifier regularly to prevent bacterial growth.
5. Cheilitis: Cheilitis may be associated with sun exposure, weather changes, or local irritation. If lip dryness persists and is accompanied by pain, itching, or peeling, it might indicate cheilitis. In such cases, follow a physician’s guidance to apply medications such as erythromycin ointment, hydrocortisone butyrate cream, or mometasone furoate gel.
After taking isotretinoin soft capsules, the skin becomes more susceptible to sunburn and dryness. Therefore, proper sun protection measures should be taken when going outdoors, such as applying sunscreen and using umbrellas or wearing hats.
