Can I take Carbimazole and Omeprazole together?

Why this happens

Carbimazole (used for overactive thyroid) and omeprazole (used for acid reflux) are processed by different pathways in the body. They do not interfere with each other's absorption, metabolism, or effectiveness.

You can continue taking both medications as prescribed by your doctor. You do not need to change the timing of your doses or take any special precautions. Always inform your doctor or pharmacist if you start any new supplements or over-the-counter medicines.

Infection (Agranulocytosis)

Stop taking carbimazole and see a doctor immediately if you develop a sore throat, mouth ulcers, high temperature, or unexplained bruising. This can be a sign of a serious bone marrow disorder where your white blood cell count drops dangerously low.

Acute Pancreatitis

Stop treatment immediately and seek urgent medical help if you develop severe, persistent abdominal pain. You must never take carbimazole again if you have previously suffered from pancreatitis caused by this medication.

Schwangerschaft

Carbimazole can cause serious harm to an unborn baby. Effective contraception must be used during treatment. If you become pregnant or plan to have a baby, you must notify your doctor immediately to discuss switching to a safer alternative.

Severe diarrhoea

Contact your doctor if you develop severe or persistent watery diarrhoea, as omeprazole can increase the risk of a serious bowel infection called C. difficile.

Lupus-like skin reactions - omeprazole

Seek medical advice if you develop a skin rash, especially in areas exposed to the sun, as this may be a sign of subacute cutaneous lupus erythematosus (SCLE).

Alkohol

While alcohol does not directly interact with omeprazole, it can increase stomach acid production and irritate the stomach lining, which may worsen the symptoms you are taking omeprazole to treat. It is best to limit alcohol intake.

While there is no direct interaction between carbimazole and alcohol, carbimazole can rarely cause liver problems. Excessive alcohol consumption can also strain the liver, so it is advisable to drink in moderation while taking this medication.

Caffeine

Caffeine (found in coffee, tea, and energy drinks) can increase stomach acid and may reduce the effectiveness of omeprazole in managing symptoms like acid reflux or heartburn.
