Is vitamin D analogue treatment done with calcipotriol?

Calcipotriol is a prescription vitamin D analogue applied to affected skin. It helps regulate excessive skin-cell activity and may reduce the thick, scaly plaques seen in conditions such as psoriasis. It is not the same as taking a vitamin D supplement, and a supplement should not be used as a substitute.

A clinician may prescribe calcipotriol alone or pair it with another topical medicine, depending on the diagnosis. The face, skin folds, scalp, and larger treatment areas may need different products or instructions because these sites can be more sensitive.

Use only the amount and frequency prescribed, apply it to the intended patches, and wash your hands afterwards. Avoid the eyes, mouth, and delicate skin unless your prescriber specifically directs otherwise. Irritation, burning, redness, or worsening scale should be reported rather than managed by silently increasing or stopping the dose.

Tell your clinician about kidney or calcium-related problems, pregnancy, breastfeeding, and other vitamin D products. Keep the medicine away from children and follow the storage instructions. Read the related guides for [Calcipotriol](/materials/calcipotriol/) and [Vitamin D Analogue Treatment](/treatments/medical-dermatology/vitamin-d-analogue-therapy/).

Contact your clinician if severe irritation, facial swelling, widespread rash, or a painful flare develops. Seek urgent help for trouble breathing or swelling of the lips or tongue. Also report symptoms such as persistent nausea, unusual thirst, constipation, or weakness, particularly if large areas are being treated.

Ask whether calcipotriol is suitable for your diagnosis and body site, how much skin to treat, whether another topical medicine should be used at a separate time, and when improvement should be reviewed. Confirm what to do if the skin becomes irritated.
