Differin gel is available in a generic form, with its active ingredient being adapalene [1].
When did Differin go generic?
The patent for Differin expired, allowing generic versions to become available. In 2017, Galderma, the original manufacturer of Differin, transitioned the product from prescription-only to over-the-counter (OTC) status, which also saw the introduction of generic adapalene products [2].
What is the difference between Differin and generic adapalene?
The primary difference between brand-name Differin and its generic counterpart is the manufacturer and, consequently, the branding and packaging. The active ingredient, adapalene, and its concentration are the same in both [1]. Generic medications are required by regulatory bodies to be bioequivalent to their brand-name counterparts, meaning they perform the same way in the body [3].
Can I buy adapalene over the counter?
Yes, adapalene, the active ingredient in Differin gel, is available over the counter for topical use in treating acne [2]. This allows consumers to purchase it without a prescription.
What is adapalene used for?
Adapalene is a topical retinoid used to treat acne vulgaris. It works by preventing and treating pimples and skin blemishes that arise from acne [1]. It helps to normalize the shedding of skin cells lining the hair follicles, thereby reducing the formation of new comedones (blackheads and whiteheads) and also has anti-inflammatory properties [4].
Are there alternatives to Differin gel for acne?
Several other topical and oral treatments are available for acne. These can include other retinoids like tretinoin, topical antibiotics, benzoyl peroxide, and in more severe cases, oral medications such as antibiotics or isotretinoin [5]. The best alternative often depends on the type and severity of acne.
How much does generic Differin gel cost?
The cost of generic adapalene gel can vary depending on the pharmacy, dosage strength, and quantity. Generally, generic medications are significantly less expensive than their brand-name equivalents [3]. Prices can range, but often a generic 30g tube of 0.1% adapalene gel can be found for under $20 [6].
What are the side effects of adapalene?
Common side effects of topical adapalene include skin dryness, redness, peeling, and mild burning or stinging sensations. These are often more pronounced when starting treatment and tend to decrease over time [1][4]. Sun exposure should be limited while using adapalene, as it can increase sensitivity to sunlight [1].
