Alfacalcidol is a synthetic form of vitamin D that is used to treat and prevent conditions related to calcium and vitamin D deficiencies, such as osteoporosis, hypoparathyroidism, and rickets. It is also used to treat conditions that cause high levels of parathyroid hormone, such as chronic kidney disease.
Alfacalcidol works by increasing the absorption of calcium from the digestive system and regulating the levels of calcium and phosphorus in the body. It is usually taken as an oral capsule or solution, and the dosage and duration of treatment may vary depending on the specific condition being treated.
While alfacalcidol is generally considered safe and well-tolerated, it can cause side effects in some people. Common side effects may include nausea, vomiting, constipation, and headache. In rare cases, it may cause more serious side effects such as high blood calcium levels, kidney stones, or an allergic reaction. It is important to use alfacalcidol only as directed and to discuss any concerns or questions with a healthcare provider.
