Osteotriol works better when taken at night to promote calcium absorption. For menopause-induced osteoporosis, the medication usually needs to be taken twice daily, and the best time to take the medication is at 8:00 am and 8:00 pm. Osteotriol is one of the metabolites of vitamin D3, which promotes calcium absorption and bone mineralization in the intestinal tract, and is used for osteoporosis and rickets caused by various reasons. The most common adverse reaction to this product is hypercalcemia, which may also trigger adverse reactions such as nausea, abdominal pain, headache, rash, urinary tract infection, epigastric pain, and constipation. This product is contraindicated in patients with hypercalcemia or signs of vitamin D toxicity. Take care to test blood calcium at least twice a week while on the drug. Note that women during pregnancy need to weigh the pros and cons of use. Patients must use the drug under the supervision of a medical professional and strictly adhere to the doctor’s instructions.
