Painkiller

Painkiller

A Painkiller or analgesic is a type of drug used to relieve pain. They work by blocking pain signals from travelling along the nerves to the brain or by interfering with the brain's interpretation of the signals. Painkillers can be classified into two main types: non-prescription, or over-the-counter (OTC), and prescription-only.

Types of Painkillers

Non-prescription Painkillers

Non-prescription painkillers, also known as over-the-counter (OTC) painkillers, are available without a prescription from a doctor. They are typically used for the relief of minor aches and pains, such as headache, toothache, muscle pain, and menstrual cramps. Examples of OTC painkillers include paracetamol (also known as acetaminophen), aspirin, and ibuprofen.

Prescription Painkillers

Prescription painkillers are used to treat moderate to severe pain. They are typically prescribed by a doctor or other healthcare professional. Examples of prescription painkillers include opioids, such as morphine, oxycodone, and fentanyl, and non-opioids, such as tramadol and certain types of antidepressants and anticonvulsants.

Side Effects and Risks

Like all drugs, painkillers can have side effects. Common side effects of painkillers include nausea, vomiting, dizziness, and constipation. In some cases, painkillers can also lead to dependency and addiction, particularly with long-term use.
