hello there! Thank you for asking i read your concern about the fosamax and i want you to know that these are bisphosphonate derivatives and they help increase calcium uptake which you need the most. and sure they ave side effects but they can be controlled with the way it is taken. i will give you some tips. Take only in morning, not at bedtime or before arising Take tablet with full glass of water (6-8 oz) at least 30 minutes before first food or drink of day, in upright position Swallow with plain water only; coffee or juice severely reduces bioavailability Swallow tablet whole; do not suck or chew Do not lie down for 30 minutes after taking drug; sit or stand upright If dietary intake is inadequate, you should receive calcium supplement and vitamin D I strongly recommend to continue the same class of drug, you can chnge the brand though by consulting your doctor. but bisphosphonates are your only option i believe here suitable for your needs Regards S Khan
