Can I take Atorvastatin and Matcha together?

Why this happens

Matcha contains compounds called catechins (like EGCG) and caffeine. Some studies suggest that high amounts of green tea catechins can interfere with the proteins (transporters) that move atorvastatin in and out of cells, or slightly slow down the liver enzymes that break the drug down. This leads to more of the medicine staying in your system.

What you should do

You do not need to stop drinking matcha, but it is best to consume it in moderation (1-2 cups a day) and avoid taking it at the exact same time as your atorvastatin. If you notice any unusual muscle pain, tenderness, or weakness, or if your urine becomes very dark, you should contact your doctor.

Important precautions

Embarazo

You must not take atorvastatin if you are pregnant or planning to become pregnant, as it may harm the developing baby. Use effective contraception while taking this medicine.

Trastornos musculares

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

Liver health

Both atorvastatin and high-strength green tea extracts (like matcha) can affect liver function. If you consume large amounts of matcha, your doctor may need to monitor your liver enzymes more closely.

Food and drink warnings

Grapefruit juice

Grapefruit juice contains compounds that can increase the level of atorvastatin in your blood. This can increase your risk of side effects, such as muscle pain or damage. Avoid drinking large quantities (more than 1.2 litres daily), though it is safest to avoid it altogether while taking this medicine.

Alcohol

While a small amount of alcohol is generally safe, drinking large amounts of alcohol regularly or binge drinking can increase the risk of liver problems when taking atorvastatin. It can also increase the risk of muscle side effects.

Productos lácteos

Adding milk to matcha may reduce the absorption of the beneficial antioxidants (catechins) found in the tea, though this does not affect the safety of the drink.

Foods high in Vitamin K

Matcha is very high in Vitamin K. If you are taking blood-thinning medication like warfarin, sudden changes in how much matcha you drink can interfere with how your medication works. Keep your intake consistent.
