Varför detta händer

Atorvastatin works by reducing the amount of cholesterol made by the liver. Cod liver oil contains omega-3 fatty acids, which help lower triglycerides (another type of blood fat). While both can slightly influence how blood cells stick together, this effect is generally not strong enough to cause clinical problems for most people.

It is generally safe to take these together. If you are also taking prescribed blood-thinning medication (like warfarin or aspirin), or if you have a planned surgery, you should inform your doctor or pharmacist before starting cod liver oil. Always stick to the recommended dose on the supplement packaging.

Graviditet

You must not take atorvastatin if you are pregnant or planning to become pregnant, as it can cause serious harm to an unborn baby. Use effective contraception while taking this medicine.

Muscle disorders - atorvastatin

Seek immediate medical advice if you experience unexplained muscle pain, tenderness, or weakness. In rare cases, this can lead to a serious condition called rhabdomyolysis which causes kidney damage.

Blood-thinning medication (e.g., warfarin)

Cod liver oil can increase the risk of bleeding if taken with blood-thinning medicines. Consult your pharmacist or doctor before combining them.

Grapefruit juice

Grapefruit juice can increase the level of atorvastatin in your blood, which may increase the risk of side effects like muscle pain or damage. Avoid drinking large amounts (more than 1.2 litres daily), though a small glass is usually safe.

Alkohol

Drinking large amounts of alcohol while taking atorvastatin can increase the risk of liver problems. It is best to keep your alcohol intake within the recommended limits. It may also increase the risk of muscle side effects.
