Medicines are substances used to prevent, diagnose, and treat diseases and maintain overall health. They can be prescribed by a healthcare professional or purchased over-the-counter (OTC) without a prescription. Medicines can come in various forms, such as tablets, capsules, liquids, injections, or topical creams. Each medicine has its unique active ingredients, dosing instructions, and potential side effects. It's essential to follow the recommended dosage and consult with a healthcare professional before taking any medicine, especially if you have underlying medical conditions or take other medications. Additionally, medicines should be stored properly and kept out of reach of children and pets to avoid accidents or misuse.
