Why not to lay down after taking fosamax?

After taking Fosamax (alendronate), it is advised not to lie down for at least 30 minutes. This precaution helps prevent potential esophageal irritation or damage, as the medication can cause irritation if it doesn’t move quickly through the esophagus. Staying upright also promotes better absorption of the medication in the stomach. Following these guidelines can help maximize the effectiveness of Fosamax and minimize side effects.
