Follow all directions on your prescription label and read all medication guides or instruction sheets. Use exactly as directed by your healthcare provider.
Using more medicine or applying it more often than prescribed will not make it work any faster, and may increase side effects. Do not use more often than your doctor or health care professional has recommended.
Do not take by mouth. Topical medicine is for use only on the skin. Do not use on sunburned skin, or skin affected by eczema.
Read and carefully follow any instructions for use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Usual dosing is as follows:
- Retin-A Micro (tretinoin gel) microsphere, 0.1% and 0.04%, should be applied once a day, in the evening, to the skin where acne lesions appear, using enough to cover the entire affected area lightly.
- Retin-A Gel or Cream should be applied once a day, before retiring, to the skin where acne lesions appear, using enough to cover the entire affected area lightly.
- Retin-A liquid should be applied once a day, before retiring, to the skin where acne lesions appear, using enough to cover the entire affected area lightly. The liquid may be applied using a fingertip, gauze pad, or cotton swab. If gauze or cotton is used, care should be taken not to oversaturate it to the extent that the liquid would run into areas where treatment was not intended.
Wash your hands before and after applying topical Retin-A (tretinoin). Before applying, clean and dry the skin area to be treated. Applying topical Retin-A (tretinoin) to wet skin may cause skin irritation.
Do not wash the treated area or apply other skin products for at least 1 hour after applying topical Retin-A (tretinoin).
Topical Retin-A (tretinoin) should be used as part of a complete skin care program that includes avoiding sunlight and using an effective sunscreen and protective clothing.
It may take up to several weeks before your skin improves. Keep using the medication as directed and tell your doctor if your symptoms do not improve. If you are using topical Retin-A (tretinoin) to treat acne, your condition may get slightly worse for a short time.
Use this medicine for the full prescribed length of time, even if you think it is not working.
If you miss a dose, use the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not apply two doses at one time.
Store at room temperature; away from moisture, heat, and light. Keep the container tightly closed when not in use.
