Can I take Colchicine and Rosuvastatin together?

Why this happens

Both drugs independently carry a risk of causing muscle toxicity. When used together, their effects can be additive, meaning they 'double up' on the potential to harm muscle cells. Additionally, colchicine can interfere with the way statins are transported and processed in the body, leading to higher levels of the medication in your system.

You must speak to your doctor before taking these together. If your doctor decides you need both, they may prescribe a lower dose or monitor you more closely. Seek medical help immediately if you experience any unexplained muscle pain, tenderness, or weakness, especially if accompanied by a fever or dark-coloured urine.

Muscle pain or weakness (Rhabdomyolysis)

Both medicines can cause muscle damage. You must report any unexplained muscle pain, tenderness, or weakness to your doctor immediately, as the risk is higher when taking these two drugs together.

Overdose risk

Colchicine is very toxic in overdose. Never take more than the prescribed dose; even a small increase can be fatal. Keep strictly to the maximum dose and duration advised by your doctor.

Pregnancy

Rosuvastatin must not be used during pregnancy as it may harm the unborn baby. You must use effective contraception while taking this medicine and stop taking it immediately if you think you are pregnant.

Grapefruit juice

Grapefruit juice can increase the level of colchicine in your blood to potentially dangerous levels. You should avoid drinking grapefruit juice or eating grapefruit while taking this medicine.

Alcohol

You should avoid drinking large amounts of alcohol while taking rosuvastatin. Regular high intake of alcohol increases the risk of liver problems and muscle side effects associated with this medicine.
