Over-the-counter pain relievers are medications that can be purchased without a prescription to help alleviate pain and reduce inflammation. Common types include acetaminophen, ibuprofen, and naproxen. These medications are often used for headaches, muscle aches, arthritis, and other minor pains. These pain relievers work by blocking pain signals in the body or reducing inflammation. While they are generally safe when used as directed, it is important to follow dosage instructions and be aware of potential side effects. Always consult a healthcare professional if you have questions or if pain persists.
