Why is this medication prescribed?
Tretinoin is used to treat acne. It promotes peeling of affected skin areas and unclogs pores. Tretinoin controls acne but does not cure it.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Tretinoin comes in topical liquid, cream, and gel. Tretinoin usually is used daily at bedtime or once every 2 or 3 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use tretinoin exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Your acne probably will get worse (red, scaling skin and an increase in acne sores) during the first 7-10 days that you use this medication. Nevertheless, continue to use it; the acne sores should disappear. Usually 2-3 weeks (and sometimes more than 6 weeks) of regular use of tretinoin is required before improvement is seen.
Use only nonmedicated cosmetics on cleansed skin. Do not use topical preparations with a lot of alcohol, menthol, spices, or lime (e.g., shaving lotions, astringents, and perfumes); they can sting your skin, especially when you first use tretinoin.
Do not use any other topical medications, especially benzoyl peroxide, salicylic acid (wart remover), and dandruff shampoos containing sulfur or resorcinol unless your doctor directs you to do so. If you have used any of these topical medications recently, ask your doctor if you should wait before using tretinoin.
If you are to apply any form of tretinoin, follow these steps:
Wash your hands and affected skin area thoroughly with mild, bland soap (not medicated or abrasive soap or soap that dries the skin) and water. To be sure that your skin is thoroughly dry, wait 20-30 minutes before applying tretinoin.
Use clean fingertips, a gauze pad, or a cotton swab to apply the medication.
Use enough medication to cover the affected area lightly. Do not oversaturate the gauze pad or cotton swab.
Apply the medication to the affected skin area only (e.g., skin with acne sores).
What special precautions should I follow?
Before using tretinoin,
tell your doctor and pharmacist if you are allergic to tretinoin or any other drugs.
tell your doctor and pharmacist what prescription and nonprescription medications you are taking, including vitamins.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using tretinoin, call your doctor.
plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Tretinoin may make your skin sensitive to sunlight.
What should I do if I forget a dose?
If you use tretinoin once a day, skip the missed dose completely. Do not use this medication more often than once a day. If you use tretinoin every 2 or 3 days and remember a missed dose within 12 hours of the time when you should have applied it, apply the missed dose immediately. Otherwise, skip the missed dose; do not apply a double dose.
What side effects can this medication cause?
Tretinoin may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
warmth or slight stinging of the skin
lightening or darkening of the skin
red, scaling skin
increase in acne sores
swelling, blistering, or crusting of the skin
What storage conditions are needed for this medicine?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
