Before Using This Medicine

In deciding to use a medicine, the risks of applying the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For adapalene, the following should be considered:

Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to adapalene. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy- Adapalene has not been studied in pregnant women. It is not recommended for use during pregnancy. Adapalene in large doses has been shown to cause some bone problems in the fetuses of some animals. Before using this medicine, make sure your doctor knows if you are pregnant or if you are trying to become pregnant.

Breast-feeding- It is not known if adapalene passes into breast milk.

Children- Studies of this medicine have been done only in adult patients, and there is no specific information comparing use of adapalene in children up to 12 years of age with use in other age groups. In teenagers, adapalene is not expected to cause different side effects or problems than it does in adults.

Older adults- Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of adapalene in the elderly with use in other age groups. Older adults are not likely to develop acne.

Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your doctor and pharmacist if you are using any other topical prescription or nonprescription (over-the-counter [OTC]) medicine that is to be applied to the same area of the skin.

Other medical problems- The presence of other medical problems may affect the use of adapalene. Make sure you tell your doctor if you have any other medical problems, especially:
  • Eczema or
  • Seborrheic dermatitis-Use of this medicine may cause or increase the irritation associated with eczema or seborrheic dermatitis

Apply the medicine to clean, dry areas of the skin affected by acne. Rub in gently and well. Wash your hands afterwards to remove any medicine that may remain on them.

To help clear up your acne completely, it is very important that you keep using this medicine for the full time of treatment , even if your symptoms begin to clear up after a short time. If you stop using this medicine too soon, your acne may return or get worse.

Precautions While Using This Medicine

During the first 3 weeks you are using adapalene, your acne may seem to get worse before it gets better. Full improvement should be seen within 12 weeks, especially if you use the medicine every day. You should not stop using adapalene if your acne seems worse at first, unless irritation or other symptoms become severe. Check with your doctor if your acne does not improve within 8 to 12 weeks.

Do not apply any topical product to the same area where you are using adapalene, unless otherwise directed by your doctor. If applied to the same area treated with adapalene, the following products may cause mild to severe irritation of the skin:

  • Hair products that irritate the skin, such as permanents or hair removal products
  • Skin products for acne (such as clindamycin or erythromycin) or other skin products containing a peeling agent (such as benzoyl peroxide, resorcinol, salicylic acid, or sulfur)
  • Skin products that cause one to be more sensitive to the sun, such as those containing spices or lime
  • Skin products that are too drying or that contain a large amount of alcohol, such as astringents, cosmetics, shaving creams, or after-shave lotions
  • Skin products that are abrasive, such as some soaps or skin cleansers

Your doctor may ask you to use other topical products, such as benzoyl peroxide, clindamycin, or erythromycin, during your treatment with adapalene. Applying the products at different times of the day will lessen the chance of causing skin irritation.

If your skin becomes too dry or red at any time, discuss with your doctor whether you should continue using adapalene. Applying creams, lotions, or moisturizers as needed helps lessen these skin problems.

During treatment with this medicine, avoid getting too much sun on treated areas and do not use sunlamps. Since your skin may be more prone to sunburn or skin irritation, use sunscreen or sunblocking lotions regularly with a sun protection factor (SPF) of 15 or more. Wear protective clothing against sun, wind, and cold weather.
