What is Codeine?
Codeine is an opioid pain medication used to treat mild to moderate pain. It is classified as a narcotic drug and works by changing the way the brain and nervous system respond to pain. Codeine is often used in combination with other medications, such as acetaminophen, to provide additional pain relief. It can also be used to treat coughing and diarrhea. Codeine can be habit-forming and is only available by prescription.
How does it work?
Codeine works by binding to specific receptors in the brain and spinal cord known as mu, kappa, and delta opioid receptors. This binding activates the receptors, leading to a decrease in the perception of pain and an increase in the release of certain neurotransmitters, such as dopamine and norepinephrine, that produce a feeling of euphoria or relaxation. Codeine also slows down the activity of the central nervous system, which can cause drowsiness and reduce the coughing reflex. The exact mechanism of action for codeine is not fully understood, but it is thought to work by inhibiting the transmission of pain signals in the brain and spinal cord.
How to take it?
Codeine is typically taken orally, in the form of a tablet, capsule, or syrup. The dosage, frequency, and duration of use will depend on the specific condition being treated and the individual's response to the medication. It is important to follow the instructions of your healthcare provider and the label on the medication bottle when taking codeine.
Here are some general guidelines for taking codeine:
- Take the medication exactly as prescribed by your doctor.
- Do not crush, break, or chew extended-release tablets.
- If you miss a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule.
- Do not take codeine in larger or smaller amounts or for longer than recommended.
- Do not stop taking codeine suddenly, as this can cause withdrawal symptoms. Your doctor will gradually decrease your dose if it is necessary to stop taking the medication.
