Codeine does not suit everybody. Some people feel very sleepy after a dose and constipation is quite common too. The bigger worry is taking it for a long time. After a few weeks your body starts to expect it and stopping can be challenging. So stick to the dose your doctor gave you. If the pain is still there when the pack runs out go back and ask.

What Are Codeine Phosphate Tablets Used For?

Codeine phosphate tablets are mainly for pain. Doctors sometimes give them for a couple of other problems too.

Pain: Codeine is for pain that ordinary painkillers have not fixed. You might get it after an injury or an operation when the pain is just too much.

Cough: If you have a dry cough that will not go away, a doctor may suggest codeine. They will tell you if it is right for you.

Diarrhoea: In some adults, codeine can stop the runs. Please do not try it yourself. Ask a doctor or pharmacist first.

It is not for everyone. Your doctor will check your health and the other medicines you take before they give it to you.

How Do Codeine Phosphate Tablets Work?

Codeine works on the brain. It changes the way your brain reads pain signals so the pain feels weaker. Once you swallow the tablet the liver turns part of the codeine into morphine. That morphine does most of the pain work. Not everyone’s body does the conversion at the same speed.

That’s why codeine can feel strong for one person and weak for another. Be careful on the first day or two. Some people get sleepy. Some get dizzy. If that happens to you, do not drive and do not use machines. Take the tablet the way your doctor told you—nothing more.

Possible Side Effects of Codeine Phosphate Tablets

Codeine can give you side effects, but a lot of people get none. The usual ones are feeling sick, throwing up, having constipation, sweating, and feeling tired. Some people get dizzy too. If you feel sleepy or dizzy, do not drive. Do not ride a bike or use machines either. Just sit down and rest until it passes.

Now the serious part. It does not happen often, but codeine can cause a dangerous reaction. Get help right away if you struggle to breathe, feel very confused, or see your face, lips, tongue, or throat swelling up. Do not sit and wait to see if it gets better.
