Summary
Meperidine is used to relieve moderate to severe pain, which is discomfort that can range from mild to intense. It's often prescribed for short-term pain relief after surgery or injury, which is harm to the body. It's not typically used for long-term pain due to the risk of dependence, which is a reliance on the drug.
Meperidine works by binding to opioid receptors, which are parts of the brain and nervous system that process pain signals. This action changes how your brain perceives pain, providing relief. Think of it like turning down the volume on a loudspeaker; Meperidine reduces the 'volume' of pain signals reaching your brain.
The usual starting dose for adults is 50 to 150 mg every 3 to 4 hours as needed for pain. The maximum dose should not exceed 600 mg per day. It's taken orally, which means by mouth, or by injection, which is a shot given into the body. Always follow your doctor's instructions.
Common side effects of Meperidine include dizziness, which is feeling unsteady, drowsiness, which is feeling sleepy, nausea, which is feeling sick to your stomach, and vomiting, which is throwing up. These effects can vary in severity and may be temporary. If they persist, talk with your doctor.
Meperidine can cause serious breathing problems, especially when starting or increasing the dose. It's habit-forming, which means it can lead to addiction. Avoid alcohol, which can increase drowsiness. It's not safe for people with severe respiratory issues or those taking MAO inhibitors, which are a type of antidepressant.

Can Meperidine be taken safely while pregnant?
Meperidine is not recommended during pregnancy unless absolutely necessary. There is limited evidence on its safety, and it may pose risks to the unborn baby.
