For Osteoporosis "I was on Daily Fosamax about 5 years ago. I had severe GERD and stopped taking it. I used calcium supplements, and in those years, I didn't have much change. Recently, after a scan, it showed that I had bone loss, so I went to the weekly Fosamax. I took it in the morning, and by that evening, I had severe backache and muscle ache that got worse. Then I had horrible bloating. I could hardly walk with the pain. I called my pharmacist, and they told me that I need to contact my doctor and to stop taking the medication. They told me that the side effect symptoms might take up to 7 months to go away. I cannot function. I will contact my doctor to see what he has planned. I would like to just take calcium and vitamin D regularly."

For Osteoporosis "I took two weekly doses of Fosamax then stopped because of side effects. Rapid weight gain, acute abdominal distension (like I’m 7 months pregnant), aching back, aching hips, fatigue, and random itching. Been off it for a month and side effects have not abated at all. It’s like I woke up and suddenly aged an extra 30 years overnight. Hope the side effects go away soon."

For Osteoporosis "MD prescribed Fosamax. Took first dose and two days later woke up with a severe headache, bloating, gas, and terrible nausea. By the time I got home from work, I had severe back pain, joint pain, and a headache. The bloating was almost intolerable. The next day, nausea was worse and the headache continued with no relief even after OTC pain meds. I will take Calcium and Vitamin D instead."

For Osteoporosis "I started taking Fosamax for Osteoporosis. I had low back pain and body aches the first week. In the second week, I had severe headaches that lasted over two days. Now it's a dull headache. I'm unsure about this medication and worried about the side effects. I hope the effects get better not worse."

For Osteoporosis "I took my first weekly dose of Fosamax on Monday. Eight hours later, diarrhea began, along with a lower backache. On Tuesday morning, I woke up to a severe backache, back and abdominal muscle spasms, and severe pain in my right hand. I am unable to write, pick up a glass, or do even the most minor thing. I can barely get up out of a chair. Now, I'm running a low-grade fever and have chills. This is a horrible medication. I will not take a second pill. I can only pray this passes."
