Acne Medications: Prescription Topical Medicines
Patients with moderate to severe inflammatory acne may be treated with prescription topical or oral acne medications, alone or in combination.
Several types of prescription topical acne medications are used for
acne treatment, including:
- Antibiotics
- Benzoyl peroxide
- Tretinoin
- Adapalene
- Azelaic acid.
Antibiotics and azelaic acid help stop or slow the growth of bacteria and reduce inflammation. Tretinoin, a type of drug called a retinoid that contains an altered form of vitamin A, is an effective topical acne medication for stopping the development of new comedones (basic acne lesions). It works by unplugging existing comedones, thereby allowing other topical acne medications, such as antibiotics, to enter the follicles. The doctor may also prescribe newer retinoids or retinoid-like drugs, such as tazarotene or adapalene, which help decrease comedo formation.
Like OTC topical acne medications, prescription topical acne medications come as creams, lotions, solutions, or gels. The doctor will consider the patient's skin type when prescribing a product. Creams and lotions provide moisture and tend to be good for people with sensitive skin. Gels and solutions are generally alcohol based and tend to dry the skin. Therefore, patients with very oily skin or those who live in hot, humid climates may prefer them. The doctor will tell the patient how to apply the acne medication and how often to use it.
Some people develop side effects from using prescription topical acne medications. Initially, the skin may look worse before improving. Common side effects include:
- Stinging
- Burning
- Redness
- Peeling
- Scaling
- Discoloration of the skin.
With some acne medications, like retinoids, these side effects usually decrease or go away after the medicine is used for a period of time. Patients should report prolonged or severe side effects to their doctor. Between four and eight weeks will most likely pass before patients see their skin improve.
