constipation, drug induced
"I've been taking opioids for back pain for almost a year so I've been dealing with constipation for about the same length of time. I took Movantik last night for the first time and within an hour I had racing heart, shortness of breath, throbbing headache. Now 20 hours later I'm so irritable I could spit and can hardly think straight. 24 hours of anxiety and cramps and nausea! I'm so grateful to see these reviews because I don't feel alone and crazy."
