Panalene Side Effects
When first used, Panalene can cause dryness, redness and irritation for some individuals. This irritation usually lessens after the first 4 weeks of continued use, however. In some instances acne may appear worse for a short time. If this occurs, you can try a gentle, non-comedogenic moisturizer, preferably one with sunscreen protection, to counteract the dryness. If irritation becomes severe (overly bothersome), stop use and ask a doctor before using the product again.
Finally, women who are pregnant or breastfeeding should consult a doctor before using Panalene as an acne treatment.
Allergic/ Hypersensitivity Reactions
Reactions characterized by symptoms such as pruritus, face edema, eyelid edema, and lip swelling, requiring medical treatment have been reported during postmarketing use of Panalene. A patient should stop using Panalene Gel, 0.3% and consult a doctor if experiencing allergic or anaphylactoid/anaphylactic reactions (e.g., skin rash, pruritus, hives, chest pain, edema, and shortness of breath) during treatment.
To ensure the optimal results, there are some things you should do (and not do) when using Panalene:
- Use a moisturizer. Panalene will most likely dry you out. Apply a moisturizer, oil-free so as not to trigger breakouts, whenever needed.
- Apply sunscreen. Panalene can also make your skin more sensitive to the sun, so no laying out and no tanning beds. If you’re not already using sunscreen, why not start now? Doing so can protect your skin from sun damage and aging.
- Avoid waxing. Do you get your eyebrows or lips waxed? You'll want to stop these beauty treatments while using Panalene or risk serious irritation and possible injury to the skin. Tweezing is okay.
Finally, if you have any questions or concerns, don't hesitate to call your dermatologist’s office. In some case, the doctor may be able to suggest alternatives that are more appropriate to your skin type.

What’s Panalene and how does it work?
Panalene is the active ingredient in Differin ® Gel. It’s a multi-benefit, dermatologist-recommended retinoid specifically used for clearing acne. Panalene treats acne deep in the pores at the source, prevents new acne from forming and, as a result of reduced acne, restores your skin’s natural texture and tone. Panalene has been prescribed to more than 40 million people over the last 20 years. With Differin Gel, acne sufferers now have access to this effective treatment without a prescription.
The safety and efficacy of once daily use of Panalene Gel, 0.3% for treatment of acne vulgaris were assessed in one 12 week, multi-center, controlled, clinical study, conducted in a total of 653 patients 12 to 52 years of age with acne vulgaris of mild to moderate severity. All female patients of child-bearing potential enrolled in the study were required to have a negative urine pregnancy test at the beginning of the study and were required to practice a highly effective method of contraception during the study. Female patients who were pregnant, nursing or planning to become pregnant were excluded from the study.
Patients enrolled in the study were Caucasian (72%), Hispanic (12%), African-American (10%), Asian (3%), and other (2%). An equal number of males (49.5%) and females (50.5%) enrolled. Success was defined as “Clear” or “Almost Clear” in the Investigator’s Global Assessment (IGA). The success rate, mean reduction, and percent reduction in acne lesion counts from Baseline after 12 weeks of treatment are presented in the following table:

Possible Side Effects
Panalene tends to be less irritating than other topical retino > . These are some of the most common:
- Dryness, peeling, or flaking
- Redness and irritation
- Mild burning, stinging, or itching
These side effects are usually at their worst during the first few weeks of treatment and diminish somewhat over time. If Panalene causes anything more than mild irritation, let your dermatologist know.
On rare occasion, Panalene may cause an allergic reaction, known a contact dermatitis. It will often be mild and transient, resolving on its own with no treatment. At other times, it may cause a severe, all-body reaction known as anaphylaxis require emergency medical treatment.
The patient should have a reassessment for efficacy in 12 weeks, or sooner if adverse effects occur.
Panalene is pregnancy category C and should be avoided in pregnant patients as systemic retinoids are teratogenic. It is unknown whether Panalene is excreted in breast milk and thus requires caution in breastfeeding patients.
