The side effects of Tricalm may include skin irritation, inflammation, burning and dryness of the affected areas, according to Drugs.com. These side effects are typical of Tricalm's active ingredient, aluminum acetate.
Tricalm is a topical anti-itch cream. It does not contain steroids or antihistamines, so users can apply it as needed, reports Cosmederm Bioscience, the ointment's manufacturer. This cream works by inhibiting nerve transmissions that would typically signal itching to the brain. It is most effective in treating skin irritations caused by insect bites, poison ivy and poison oak, and rashes caused by exposure to detergents, cosmetics and jewelry. It is also a known anti-itch treatment for skin irritations caused by exposure to cold and drying weather, in addition to other disorders for which irritated skin is a symptom.
Aluminum acetate, the active ingredient for Tricalm, is a common anti-itch medication. Users should only apply the medication topically, and they must never apply it to open wounds, notes Healthline.com. Users should not compress or dress the area. Storage of medications containing aluminum acetate should occur in cool dry places, or at room temperature.
The product label provided by Walgreens.com states that aluminum acetate is present at a concentration of 0.2 percent in Tricalm. However, Cosmederm Biosciences also offers Tricalm: Extra Strength, which has an aluminum acetate concentration of 0.3 percent, according to Drugs.com.
