Taken by injection, self- or doctor-administered. If self-administered, follow doctor’s instructions carefully; must inject under the skin or into a muscle, not into a vein. To avoid nausea, vomiting, and skin flushing, take injection at bedtime. Do not use Calcimar solution if it has a color change or particles floating in it. If taking for postmenopausal osteoporosis, make sure your diet includes foods rich in calcium and vitamin D.
