Can I take Atorvastatin and Spironolactone together?

Varför detta händer

Spironolactone is a 'potassium-sparing' diuretic that prevents your body from flushing out potassium. While atorvastatin does not directly affect potassium, some studies suggest that statins may occasionally interfere with how the kidneys manage minerals, or in rare cases of muscle breakdown (rhabdomyolysis), potassium levels can rise sharply.

It is generally safe to take these together if prescribed by your doctor, but you should have regular blood tests to check your potassium levels and kidney function. Seek medical advice if you experience unexplained muscle pain, tenderness, or weakness, or if you feel heart palpitations or unusual tiredness.

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.

High potassium levels (Hyperkalaemia)

Spironolactone can cause dangerously high potassium levels. You must avoid using potassium supplements or salt substitutes containing potassium, and your doctor will need to monitor your blood regularly.

Grapefruit juice

Grapefruit juice contains compounds that can increase the level of atorvastatin in your blood. This may increase your risk of side effects, such as muscle pain or damage. Avoid drinking large quantities (more than 1.2 litres per day), though it is safest to avoid it altogether or keep intake to very small amounts.

Alkohol

Drinking alcohol while taking atorvastatin can increase the risk of liver problems. For spironolactone, alcohol can increase the medicine's blood-pressure-lowering effect, which may make you feel dizzy or lightheaded.

High-potassium foods (e.g., bananas, avocados, spinach) and salt substitutes

Spironolactone helps your body retain potassium. Eating large amounts of potassium-rich foods or using 'low-sodium' salt substitutes (which often contain potassium) can cause your potassium levels to become dangerously high.
