It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for any unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.

You may notice redness, stinging, burning or irritation when you first start using this medicine. It may take up to 6 months before you notice full beneficial effects, even if you use the medicine every day. Check with your doctor at any time skin irritation becomes severe or if your age spots get darker in color.

Unless your doctor tells you otherwise, it is especially important to avoid using the following skin products on the same area as mequinol and tretinoin topical solution:

  • Hair products that are irritating (eg, permanents, hair removal products).
  • Skin products that cause sensitivity to the sun (eg, products containing spices or limes).
  • Skin products containing a large amount of alcohol (eg, astringents, shaving creams, after-shave lotions).
  • Skin products that are too drying or abrasive (eg, cosmetics, soaps, or skin cleansers).

Avoid overexposing the treated areas to sunlight, wind, or cold weather. The skin will be more prone to sunburn, dryness, or irritation. Do not use a sunlamp.

Regularly use sunscreen or sunblock lotions with a sun protection factor (SPF) of at least 15. Also, wear protective clothing and hats, and apply creams, lotions, or moisturizers often.

Check with your doctor any time your skin becomes too dry and irritated. Your doctor can help you choose the right skin products for you to reduce skin dryness and irritation and may include:

  • Taking part in an ongoing program to avoid further damage to your skin from the sun. The program should stress staying out of the sun when possible and wearing proper clothing or hats to protect your skin from sunlight.
  • Regular use of oil-based creams or lotions to help to reduce skin irritation or dryness caused by the use of mequinol and tretinoin topical solution.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
