Pethidine
About Pethidine
Pethidine is a strong pain-relieving medication used to manage moderate to severe pain. It is commonly used in medical settings to treat sudden pain after surgery, severe injuries, or during childbirth. It is also sometimes given before surgery to help you relax and stay comfortable.
Because this medicine is highly potent and potentially habit-forming, it is only given for short periods and not as a regular, daily treatment. It is injected into your body by a healthcare professional, either into a muscle, under the skin, or directly into a vein. To help your body cope with the side effects of strong pain relievers, it is highly recommended to drink plenty of fluids and eat high-fibre foods to support your digestive health.
While this medicine is highly effective, it can cause common side effects like drowsiness, nausea, and dizziness. You must talk to your doctor immediately if you experience serious side effects, such as shallow breathing, extreme confusion, or severe allergic reactions like swelling or breathing difficulties.
Before you are given this medicine, it is vital to discuss your medical history with your doctor, especially if you have asthma, lung disease, kidney or liver damage, head injuries, or thyroid problems. Do not take this if you have severe breathing issues, bowel blockages, or if you have taken certain antidepressants (MAO inhibitors) in the last 14 days.
This medicine can interact dangerously with alcohol, sleeping pills, and other medicines that cause drowsiness, leading to extreme sleepiness or slowed breathing. If you are pregnant, breastfeeding, or an older adult, talk to your doctor or pharmacist before receiving this medicine to ensure it is safe for you and your baby.

Patients Concern
Disease/Condition Glossary
Pain: Pain is an unpleasant emotion brought on by an illness or injury. Acute or chronic pain both exist. Since different people have varying pain tolerance levels, pain is highly subjective. Even though pain is uncomfortable and inconvenient, it can provide clues as to what is wrong with the body. Cramps, headaches, bone fractures, stomach pain, arthritis (swelling of one or more joints), muscle strain or overuse, cuts, the flu, fibromyalgia, and irritable bowel syndrome are a few conditions that can cause pain (muscle pain with stiffness and tenderness).
