I took fosamax for four weeks and stopped taking it due to the severe muscle and joint pain I developed, which still has not subsided since stopping taking this POISON over 2 months ago. This drug should be taken off the market!!!!!!! I reported it to the FDA but I doubt anything will be done until they can prove someone dies from it. The drug companies are way too powerful pushing thier POISONS and the doctors are too stupid and gullable!!!!!!!!!!!!!!!!!!!!!!! Will never take this class of drugs again.
