For Osteoporosis "I’ve been on Fosamax for 3 weeks, taking it once a week, on a Sunday. The first week I was constipated and bloated. That lasted most of the week. I started my second round on Sunday. By Monday afternoon, I started having joint and muscle pain. By late in the afternoon, my knees were swollen, and I had difficulty walking and climbing stairs. By Thursday, I was feeling back to normal. This past Sunday, I took my third pill. The next day, I had joint and muscle pain, flu-like symptoms, headache, nausea, fever, and chills. I’ve decided to stop the medication and take coral calcium and a vitamin D supplement."

For Prevention of Osteoporosis "At age 47, my OB-GYN informed me I had 'osteopenia' - the beginnings of osteoporosis. 'It's hereditary,' the doc said after I divulged in my medical Q&A the 'fact' that my mother, then 67, had been diagnosed with osteoporosis. He prescribed Fosamax. Though skeptical (I was so young!), I picked it up at the pharmacy. Two weeks went by before I decided to just go ahead and take it. I took it at around 9:00 in the morning of the 4th of July. I had guests arriving later that day. Around 10:00 a.m., my daughter and I walked several blocks to a 4th of July parade in town. While walking, I felt a strange chemical-like cold/chilling sensation migrating up from my left knee into my femur. I remember thinking, how odd, it's as if it's actually beginning to work - almost instantly?? By 3:00 that afternoon, when guests were due to arrive, I began to feel feverish, weak, and exhausted. I had a 102-degree temperature, severe chills, and nausea. Needless to say, I knew the Fosamax was to blame. I threw the remaining pills away and am SO glad I did! Fosamax for 'mild osteopenia' (I now contend there is no such thing)."

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."

For Osteoporosis "I was asymptomatic but deemed high risk for fracture since diagnosed with osteoporosis. I respect some who’ve actually benefited from Fosamax. However, this has been a drug nightmare with symptoms similar to others here on this site. First week taking weekly Fosamax 70 followed next day by nonstop diarrhea for remainder of the week. Second week dose 2 had ongoing diarrhea, chills, nausea, fatigue, and debilitating cramps as if punched repeatedly in the stomach. To my FP’s irritation, I strongly refused further treatment after 2 weeks, stopping prior to the 3rd dose. Also declined Prolia injectable as an alternative as it must be followed by oral biophosphonates after injections are discontinued. I’m still dealing with diarrhea and fatigue impacting the quality of life. Please do extensive reading on side effects before pursuing Fosamax or other bone health drugs. I’m now pursuing a more natural option through exercise, nutrition, vitamins D3, calcium, K2, and fish oil."

For Osteoporosis "After just one dose, seven hours later, I had a fever, chills, nausea, fatigue, and stomach issues. The second day, I was tired and chilled in the evening with bone pain in my back and also the third morning. Very achy. I am considering not taking any more doses."

For Osteoporosis "Worst medication I have ever taken. I started Fosamax 2 weeks ago, followed the directions exactly for my first dose. Within 10 hours, I was vomiting, headache, chills, fever, ached all over like severe myalgia. A week later, I took my second dose not sure if my initial reaction was a flu bug. Nope, 15 hours later it started all again and more severe. I couldn’t walk, horrible sharp pain in my hip, plus all the stomach stuff. No thanks, this is no way to live. I’ll stop taking this awful drug."
