What is Zapain?

Zapain is a brand of co-codamol - an opioid analgesic (painkiller) which is combined with a non-prescription pain reliever (paracetamol) to provide more effective relief than either ingredients alone.

Zapain tablets contains 30mg of codeine and 500mg of paracetamol which effectively reduce severe pain.

Buy Zapain Online

You can buy Zapain online from Prescription Doctor by simply filling in our quick and easy consultation form, which our expert prescriber will review. If you order before 3pm, you could have your pain relief medication the next day.

How does Zapain work?

Codeine in Zapain

the codeine in Zapain interacts with the central nervous system (CNS) to change the way the brain perceives pain. Zapain works by mimicking the action of pain-reducing chemicals, known as endorphins, which occur naturally in the brain and spinal cord.

The human body converts codeine into morphine, another type of opioid. Once converted, the morphine molecules latch onto the opioid receptors in the CNS. When codeine binds with the receptors, they send a pain-reducing message to the brain.

Paracetamol in Zapain

Paracetamol works in the central nervous system to relieve mild to moderate pain in a different way. This medicine inhibits the production of prostaglandins, which are naturally occurring chemicals that produce pain and inflammation at the site of injury or disease.

Together, codeine and paracetamol work better to provide pain relief than either medicine could provide alone.

All oral pain pills must be digested in the stomach before they begin to work. Patients typically experience relief in 30 to 45 minutes after taking a pill. Zapain is a slow release medication and can provide relief from pain for up to 6 hours.

What are the Uses, Dosage, Side Effects and Warnings?


Zapainis commonly used to treat severe pain. Our registered prescribers can determine the correct dosage for you based on the severity of your pain, source of pain and your medical history. If our prescribers determine that Zapain is not a suitable treatment for you, they may offer alternative treatments options.


Take the prescribed dose every four to six hours when necessary.

If you take more Zapain than prescribed or exceed the maximum quanity, consult a physician immediately even if you feel fine. Taking excessive amount of paracetamol can cause delayed onset liver damage. The risk of paracetamol overdose is greater in those with alcoholic liver disease.

If you go to the hospital, ensure you take the remaining tablets in the original packaging so that doctors know exactly what you have taken.

Warning: Zapain treatment and pregnancy

Do not take Zapain if you are pregnant unless instructed to do so by your doctor. Do not take Zapain while you are breastfeeding, as the codeine in this product passes into breast milk.

How Do I Take Zapain?

Adults should take one or two tablets every four to six hours with a glass of water.

Always take Zapain exactly as prescribed by our online prescriber. Check with your prescriber if you are not sure how to take Zapain.

Do not take more than two tablets at a time, or take more often than every four hours. 

Do not take Zapain for more than three days, as the risk of opiate addiction increases with prolonged use. If your pain does not improve after three days on Zapain, consult with your doctor.

Paediatric population

Zapain is not suitable for children. The metabolism of codeine is unpredictable in children and therefore should be avoided.

How do I store Zapain tablets?

Keep the medication stored out of sight and reach of children.

Do not store in locations where the temperature exceeds 25 degrees Celsius. Store this medication in its original packaging.

When you have finished with this medication, ask your pharmacist how to dispose of any unused tablets. To protect the environment, do not dispose of unused medication via household waste or wastewater.

Expiry dates

You can find the expiry date printed on the package. The expiry date on the package refers to the last day of that month. Do not take take the medication after the expiry date.

Cautions and exclusions
