Kan jag ta Co-codamol och Sukkarto tillsammans?

Guide för läkemedelsinteraktioner

There is no direct interaction between co-codamol and Sukkarto. However, both medications can sometimes cause stomach-related side effects like nausea or constipation, which may be more noticeable when taken together. Additionally, if you have severe kidney or liver problems, your doctor may need to adjust the doses of both medicines.

It is generally safe to take these co-codamol and Sukkarto (metformin) together as they are processed by the body through different pathways.

Co-codamol works on pain receptors in the brain and spinal cord, while Sukkarto works on how the liver produces glucose and how cells respond to insulin. They do not interfere with each other's absorption or metabolism.

How to take co-codamol and Sukkarto safely

  • Ensure you follow the prescribed doses for both.

  • Co-codamol can cause constipation and Sukkarto can sometimes cause an upset stomach, drink plenty of water and monitor for any digestive discomfort.

  • If you feel very unwell or experience severe stomach pain, contact your GP.

Viktiga försiktighetsåtgärder

Paracetamolförgiftning

Co-codamol contains paracetamol. Do not take it with any other paracetamol-containing products (such as cold and flu remedies), as this can lead to fatal liver damage.

Opioid addiction and withdrawal

Co-codamol contains kodein, which can cause addiction if used for more than 3 days. Stopping suddenly after long-term use can cause withdrawal symptoms.

Andningssvårigheter

Do not take co-codamol if you have severe asthma or breathing problems, as the codeine can dangerously slow your breathing.

Lactic acidosis risk (dehydration)

If you develop severe vomiting, diarrhoea, or a high fever, stop taking metformin and contact a doctor immediately.

These conditions can lead to severe dehydration, which significantly increases the risk of a rare but life-threatening build-up of acid in the blood (lactic acidosis).

Contrast dye scans (e.g., CT or X-ray)

You must tell your doctor you take metformin if you are having a scan involving an injection of 'contrast dye'. You will usually need to stop taking metformin 48 hours before and after the procedure to prevent kidney damage.

Varningar för mat och dryck

Alkohol

You must avoid drinking alcohol while taking co-codamol. Combining alcohol with codeine increases the risk of serious side effects, such as extreme sleepiness, breathing difficulties, and loss of consciousness. Additionally, both alcohol and paracetamol can affect the liver; combining them regularly increases the risk of liver damage.

It is best to avoid or strictly limit alcohol while taking metformin. Drinking alcohol with this medicine increases the risk of a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood). It also increases the risk of low blood sugar (hypoglycaemia).

Grapefruktjuice

Grapefruit juice can interfere with how your body processes codeine, potentially making the medicine less effective or increasing the risk of side effects. It is best to avoid grapefruit juice while taking this medicine.

Koffein

Some versions of co-codamol already contain caffeine. If you consume extra caffeine from coffee, tea, or energy drinks, it may make you feel shaky, anxious, or cause a racing heart.

Vitamin B12 absorption

Long-term use of metformin can prevent your body from absorbing enough vitamin B12 from your food. You may need to have your B12 levels checked by your doctor or take a supplement if you develop symptoms like extreme tiredness or a sore tongue.
