constipation, drug induced
"My gastroenterologist prescribed Amitiza to help with constipation caused by a medication I am taking.  I took one capsule (24 mcg) daily for five days, then began taking two (48 mcg) daily (too bigger dose?). The medication worked wonderfully to help relieve the constipation, but the side effects I am experiencing may cause me to stop taking it. I am having headaches, runny nose, fatigue, overall "bad" feeling, muscle pain, chills, nausea, and a sensation of almost passing out. I consider these side effects pretty drastic. It's possible they will go away or minimize if I continue to take the capsules, but I'm not sure I'm willing to risk it."
