What side effects are possible with Retisol-A?

Many medications can cause side effects. A side effect is an unwanted response to a medication when it is used in normal doses. Side effects can be mild or severe, temporary or permanent.

The side effects listed below are not experienced by everyone who uses this medication. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor.

The following side effects have been reported by at least 1% of people using this medication. Many of these side effects can be managed, and some may go away on their own over time.

Contact your doctor if you experience these side effects and they are severe or bothersome. Your pharmacist may be able to advise you on managing side effects.

  • burning, stinging, warmth, or tingling sensation of the skin lasting for a short time after applying
  • chapping or slight peeling of the skin
  • redness of the skin

Some people may experience side effects other than those listed. Check with your doctor if you notice any symptom that worries you while you are taking this medication.





Are there any other precautions or warnings for Retisol-A?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Application: Avoid excessive use of tretinoin. Avoid contact with the eyes, eyelids, angles of the nose, mouth, easily irritated areas, or other areas where treatment is not intended. Do not apply tretinoin to severely inflamed skin or to open lesions. Do not over-apply the cream. Doing so will not speed up treatment and will irritate your skin.

Skin care: Cosmetics may be used, but thoroughly cleanse the areas to be treated before applying the medication. Oil-based cosmetics should be avoided. Instead, use oil-free, water-based products.

Try to avoid products applied to the skin that have high concentrations of alcohol, spices or lime as they cause stinging and burning on treated skin. If possible, avoid simultaneous use of harsh abrasives and other skin treatments, including sun lamps.

Hair removal is permitted as usual (e.g., plucking, electrolysis, depilatories) but avoid these procedures at night before applying tretinoin as they may result in skin irritation.

Permanent wave solutions, waxing preparations, and medicated soaps and shampoos can sometimes even irritate skin that is not being treated with this medication. Use caution so that these products do not come into contact with skin treated with tretinoin.

Skin irritation: Some people may experience temporary skin irritation, especially in early weeks of treatment. Should excessive reactions occur, and the skin becomes extremely red, swollen, and crusted, the medication should be stopped and you should contact your doctor.

An apparent worsening may develop due to the medication's effect on existing deep lesions. This is a normal part of the treatment effect. Treatment should be continued.

If you are using this medication, you may be more sensitive to exposure to wind and cold.

Sunlight exposure: Exposure to sunlight, including ultraviolet sunlamps, may cause more irritation. Therefore, avoid or minimize this type of exposure during the use of tretinoin. If you cannot avoid exposure to sunlight, use sunscreen products (minimum SPF 15) and wear protective clothing over treated areas. Do not apply this medication to skin that has a sunburn until the skin has fully recovered.

Pregnancy: This medication is not recommended for use during pregnancy. Women who may become pregnant should use an effective method of birth control while they are using this medication. If you become pregnant while using this medication, stop using it and contact your doctor.

Breast-feeding: It is not known if tretinoin passes into breast milk. If you are a breast-feeding mother and are using this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children.

What other drugs could interact with Retisol-A?

There may be an interaction between tretinoin and any of the following:

  • medications that increase the skin's sensitivity to sunlight (e.g., isotretinoin, sulfamethoxazole, trimethoprim, minocycline)
  • medicated or abrasive soaps and cleansers
  • other skin-applied medications
  • products with high concentrations of alcohol, astringents, spices, or lime
  • skin preparations containing sulfur, resorcinol or salicylic acid
  • soaps and cosmetics with a strong drying effect

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
