Calcitriol 0.25 mcg is the active form of vitamin D3 used to treat conditions like chronic kidney disease, hypoparathyroidism, and calcium or vitamin D deficiency-related bone disorders such as rickets (soft and weak bones in children due to vitamin D deficiency) and osteomalacia (soft bones in adults caused by lack of vitamin D.

It works by helping the body absorb more calcium and phosphorus from food, reducing calcium loss through urine, and lowering parathyroid hormone (PTH) levels to maintain proper calcium balance and bone health. Because it is a very potent form of vitamin D, even a small overdose can lead to high calcium levels (hypercalcemia) in the body, causing symptoms like nausea, vomiting, weakness, excessive thirst, and kidney problems. To use it safely, it’s important to follow the prescribed dose, avoid extra calcium or vitamin D supplements unless advised, and get regular blood tests to monitor calcium and kidney function. 

Calcitriol 0.25 mcg is an oral medicine used to treat following indications: 

1. Osteoporosis (weak and brittle bones)

Calcitriol 0.25 mcg is the active form of vitamin D3, and it helps the body absorb calcium and phosphorus from the food we eat. It works mainly in the intestines by increasing the amount of calcium that enters the bloodstream. It also helps the kidneys hold on to calcium so that less is lost in urine. In addition, calcitriol plays an important role in keeping bones healthy by maintaining the right balance of calcium, and it helps control the levels of parathyroid hormone (PTH), which can affect bone strength. Overall, it supports strong bones and proper calcium levels in the body.   

Avoid taking Calcitriol 0.25 mcg with the following medicines, as it may increase or decrease the desired effect, or in worse cases, it could be fatal: 

Don’t eat too many calcium-rich foods (like cheese or milk) or take calcium tablets unless your doctor says so. Too much calcium along with calcitriol can be harmful to your body.
