We have one medicated product that contains menthol at inactive levels, our anti-itch gel called Calagel.
All product labels can be found here in our Tips and Info section.

Calagel Medicated Anti-itch Gel is an over-the-counter medication that has a two year expiration date from the day it is manufactured. The date can be found marked near the batch code vertically on the side of the bottle label. It will be marked as "EXP month/year", so for example EXP 6/2018 would expire in June 2018. If you purchase Calagel in a box with a 2 oz. Tecnu Original inside, the expiration date will also be stamped on the bottom of the box.

The drug facts label on Calagel states, "Stop use and ask a doctor if condition worsens or if symptoms persist for more than 7 days, or clear up and occur again within a few days."

If you have been using Calagel on your rash for over a week now and are starting to notice increased redness and irritation, we would suggest you discontinue use and contact your doctor.

No, you should not use Calagel if you are allergic to sulfites. Tecnu Rash Relief Spray would be another option for itch relief.

We are not aware of any side effects of Calagel. However, if you are allergic to sulfites, you could experience: a reaction that can vary from mild to life threatening. The most common symptoms are mild and involve a skin rash accompanied by redness, hives, itching, flushing, tingling, and swelling. Respiratory symptoms include difficulty breathing, wheezing, and stridor. Gastrointestinal reactions involve nausea and stomach cramps. Less common but more serious signs include low blood pressure, shock, extreme difficulty breathing, and loss of consciousness. DO NOT USE Calagel IF ALLERGIC TO SULFITES.
