Why can't I lie down or bend over after taking Fosamax?
Fosamax® (alendronate) is a drug that prevents and treats the bone-thinning disorder osteoporosis. Fosamax® slows bone breakdown, builds bone mass, and reduces the chance that bones will break. It also treats Paget's disease (weak or deformed bones).
As with many medications, there are strict directions for taking Fosamax®. For the
drug to be most effective:
- Take Fosamax® on a
totally empty stomach - before taking any other medication or eating or drinking anything other
than 6 to 8 oz of plain water, and
- Remain upright for at least 30 minutes after taking Fosamax®.
Why such strict directions? Sitting, standing, or walking upright helps ensure the medication reaches your stomach quickly. It also helps prevent the drug from irritating your esophagus, which could happen if you bend over or lie down during those first 30 minutes. Contact your doctor if you experience chest pain, worsening heartburn, or pain when you swallow.
Fosamax® side effects
common side effects are usually mild and include stomach pain, heartburn, constipation,
diarrhea, gas, stomach fullness, and muscle pain. Severe side effects can include pain,
swelling, or bleeding in the throat, with a feeling of chest pain or heartburn and painful
swallowing. This severe reaction can usually be avoided if you follow instructions
