What are the side effects of analgesics?

Analgesics can cause a variety of side effects. These side effects include allergic symptoms like hoarseness, swelling, difficulty breathing, hives, itching, and rash. They may cause stomach upset, constipation, diarrhea, dizziness, or headache. If you experience any of these side effects, or other abnormal symptoms, you should speak with your doctor right away.

Analgesics, including aspirin and acetaminophen, are medications used to treat pain. They can also have side effects. Aspirin can lead to heartburn, nausea or vomiting, stomach ulcers and gastrointestinal bleeding, and increased clotting time for blood. Acetaminophen is relatively free of side effects. There are some findings that indicate taking over-the-counter analgesics regularly to prevent pain may actually cause more pain in the end. Overuse of over-the-counter analgesics is widespread; the annual consumption of aspirin alone in this country is measured in the thousands of tons. Unfortunately, when someone with headache takes daily medication for symptom relief, a vicious cycle can occur where recurrent pain is chased by still more analgesics or pain medications with ever-decreasing efficacy requiring even more drugs.
