Can I take Codeine and Morphine together?

Varför detta händer

Both codeine and morphine work by attaching to the same receptors in the brain and spinal cord to block pain. Additionally, the body naturally converts a portion of codeine into morphine after you swallow it. Taking both means you are essentially taking a double dose of morphine, which can overwhelm the central nervous system.

You should not take codeine and morphine together unless specifically instructed and closely monitored by a specialist. If you have been prescribed both, speak to your doctor or pharmacist immediately to clarify the dosing schedule. Seek emergency medical help if you experience extreme drowsiness, confusion, shallow breathing, or difficulty waking up.

Breathing problems (e.g. COPD, severe asthma)

These medicines can dangerously slow your breathing. Do not take them if you have severe lung disease or are having an asthma attack.

Alcohol consumption

Drinking alcohol while taking these medicines significantly increases the risk of life-threatening breathing difficulties and extreme sleepiness.

Addiction and Dependency

Codeine contains an opioid which can cause addiction if used for more than 3 days. Long-term use can lead to withdrawal symptoms when you stop.

Breastfeeding

Do not take codeine while breastfeeding. It passes into breast milk and can cause life-threatening breathing problems or extreme sleepiness in your baby.

Alkohol

It is best to avoid or strictly limit alcohol while taking these medicines. Combining alcohol with strong painkillers like codeine or morphine significantly increases the risk of dangerous side effects, such as extreme sleepiness, breathing difficulties, and a potentially fatal overdose.

Grapefruit juice

Grapefruit juice can interfere with how your body processes codeine. This may make the medicine less effective at relieving pain or, in some cases, increase the risk of side effects. It is best to avoid drinking large amounts of grapefruit juice while taking codeine.
