HI
Thanks for posting your query to Healthcaremagic.
First I will list the common side effects of
Alendronate .
Burning sensation in food Pipe , Ulcers in food Pipe, Perforation, Stricture of food pipe .
Stomach Pain , Stomach Ulcers , Acid regurgitation,
Nausea,
Indigestion.
Skin Rashes.
Low calcium levels , Muscolosketal Pain .
These side effects happen in some people and not in all. Also with continued usage of medicines these side effects may go off . So wait for a week and see if still it persists ask your doctor for an alternative.
In fact there is an Injection called Zolendronate which can be given once a year. Kindly ask your doctor for that.
Hope you find this information useful.
Any clarifications or Queries feel free to ask
