What is Vectical?
Vectical (calcitriol) is a form of vitamin D. It works by decreasing the rate of skin cell reproduction.
Vectical ointment is used to treat plaque psoriasis (raised, silvery flaking of the skin) in adults.
Vectical is not for use in treating severe forms of psoriasis (with pus, skin peeling, severe redness).
You should not use Vectical ointment if you have a severe form of psoriasis (with pus, skin peeling, severe redness).
Before using Vectical, tell your doctor if you have low or high levels of calcium in your blood, a calcium disorder or metabolic imbalance, or if you are receiving UV light treatments (phototherapy) for your psoriasis.
Tell your doctor about all other medicines you are using to treat psoriasis. Also tell your doctor if you are taking a diuretic (water pill) or vitamin or mineral supplements that contain calcium or vitamin D.
Vectical ointment is for use only on areas of psoriasis. Avoid getting it on healthy skin areas. The ointment should not be applied to the face or the vaginal area.
Stop using Vectical and call your doctor if you have a serious side effect such as blistering or severe redness, itching, or other irritation of treated skin. Using this medicine can affect your body's ability to metabolize calcium. This can result in high levels of calcium in your blood (hypercalcemia). Symptoms of this condition include nausea, loss of appetite, constipation, increased thirst and urination, muscle weakness, confusion, and feeling tired or restless. Call your doctor if you have any of these symptoms.
