OTC drugs are medications that can be purchased without a prescription. They provide symptomatic relief for minor health issues like pain, coughs, or acid reflux. While convenient, OTC drugs still carry risks if not used properly. Common OTC drug types include analgesics, antibiotics, cough suppressants, and antacids. Special patient groups like children, pregnant women, and the elderly are more susceptible to side effects. Proper OTC use involves knowing what you're taking, following dosage instructions, and not exceeding recommended durations of use. Pharmacist counseling can help ensure the safe and rational use of OTC medications.
