There is no specific course of treatment for Fosamax, as it has no significant adverse effects over a long period of time and is ideal for the treatment and prevention of osteoporosis. Therefore, the course of treatment generally varies from person to person, and can be taken until the bone mass increases significantly to normal or tends to be normal, then the drug can be stopped. If you have problems with calcium absorption or calcium intake, you need to take calcium tablets and vitamin D at different times. General osteoporosis can be significantly improved within two years of treatment, but only if there are no significant adverse reactions, such as abdominal pain, bloating, indigestion, esophageal ulcers, dysphagia and other gastrointestinal discomfort, or allergic symptoms such as rash, erythema and hives. Patients with inflammation, ulcers or erosions in the esophagus as well as the stomach should be wary of serious adverse reactions such as perforation and bleeding when taking this drug.
