What Experts Say

Cholecalciferol is the inactive form of vitamin D that the liver and kidneys convert into its active hormone form. A single high dose intramuscular injection creates a fat tissue depot that releases vitamin D gradually over several weeks, unlike a daily oral tablet.

Physicians in Pakistan often choose the injectable route when a patient has malabsorption from conditions such as celiac disease, chronic pancreatitis, or bariatric surgery, or when adherence to a long daily oral course is unreliable. The injectable mega dose corrects deficiency faster than staged oral regimens in these situations.

Serum 25-hydroxyvitamin D levels are usually checked before dosing and rechecked after two to three months to confirm response. Repeat dosing is guided by these levels rather than fixed intervals, since excessive cumulative dosing can raise calcium levels and cause toxicity.
