Calcipotriol 50: what should you know?

Calcipotriol is a manufactured form of vitamin D activity for the skin. It helps regulate the rapid production and maturation of skin cells that can contribute to thick, scaly plaques. It is commonly prescribed for psoriasis, although the exact product, strength, and body area matter.

The number in a product name may refer to its strength or formulation, so do not substitute one product for another without checking the label and prescription.

Apply only the amount and frequency prescribed, usually to affected skin rather than healthy surrounding skin. Wash your hands after application unless your hands are the treated area, and keep the medicine away from the eyes, mouth, and sensitive folds unless your clinician specifically instructs you otherwise.

Do not cover treated skin with an airtight dressing unless advised. Mild irritation, stinging, or redness can occur. Tell your clinician about other vitamin D products, calcium supplements, kidney problems, or medicines for psoriasis so the treatment plan can be checked.

Contact your prescriber if irritation is severe, the treated area becomes very inflamed, or the condition is not improving as expected. Seek urgent help for facial swelling, widespread hives, breathing difficulty, or other signs of a serious allergic reaction.

Ask which areas to treat, how long to continue, whether it can be combined with another topical medicine, and what to do if you miss an application or develop irritation.
