Had outpatient surgery that I was prescribed Percocet 5mg every 4 hours and I find it really causes my heart to beat faster and I've felt irritable like it increases my energy. Called the surgeon and she couldn't see any reason why the Percocet would be causing increased blood pressure as well as heart rate. Am I crazy? Is there any other type of pain pill I could ask to be on that doesn't do this? It does work for the pain so is this the Percocet or just opioids in general? Suggestions?
