<s>[INST] I am a osteoporosis patient, recently met with an accident and fractured my T12 verterbrae (wedge compression fracture)and put on Gem cal (1000mg/day)and Gemfos(every week) for the last one year. Ive taken alcosta injection also. I am being prescribed pantocid DSR (40mg) now to alleviate the pain in the abdominal region by a gatro entrologist. My question is, whether it has got any side effects? [/INST] Hello, As you are an osteoporosis patient you must have been put on Gemcal, Memphis, these two medications can have side effects like heartburn, cause, reduced appetite, occasionally constipation to relieve you from this you have also been prescribed PAN DSR, can u please tell if the injection you mentioned is Acosta or Alaska, because I'm not sure what Acosta injection is, Alaska injection can be given to people suffering from osteoporosis, this also have Gastrointestinal side effects, like nausea, heart burn, constipation again for which PAN DSR, will do the job, it has other side effects that can occur rarely like lightheadedness, headache, reaction at the injection site, flu like symptoms, fever with chills, tiredness, bone/muscle/joint pain. And it should not be taken if you have kidney problem. If you get any of these symptoms you should consult your doctor immediately. Hope I could help you. Thank you. </s>
