The FDA  has approved Differin Gel  for over-the-counter use. Up until now it has only been available with a prescription. Currently, it is the only available over the counter retinoid on the market.

According to the manufacturer  Galderma’s website, Differin Gel is indicated for the topical treatment of acne vulgaris in those who are 12 years of age or older.

Differin Gel was approved by the FDA for prescription use in 1996. Its active ingredient is a synthetic retinoid which helps treat acne.

How does a prescription only medication become available as an over the counter medication?

The process of transferring an FDA approved  prescription medication to a nonprescription over-the-counter (OTC) medication is known as Rx-to-OTC switch.

An application known as new drug application  (NDA) must be sent to the FDA.

The application  is usually submitted by the manufacturer as they have the greatest safety information about the medication. The FDA will then review the submitted application and determine the safety of the medication as an over the counter drug.

What is the difference between retinoids and retinols.

Retinoids have a higher concentration of the active ingredient (retinoic acid).

Retinols can be converted into retinoic acid but it takes some work, these extra steps may cause the product to lose some of its potency.
