What are the possible side effects of calcitriol topical (Vectical)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Stop using calcitriol topical and call your doctor at once if you have any of these serious side effects:

  • blistering, or severe redness, itching, or other irritation of treated areas; or

Using calcitriol topical can affect your body's ability to metabolize calcium. This can result in high levels of calcium in your blood (hypercalcemia).

Call your doctor if you have any of these symptoms.

Less serious side effects may include mild itching or skin discomfort.
