Can I take Bisoprolol and Simvastatin together?

Drug interaction guide

There is no direct interaction between bisoprolol and simvastatin. However, both medications can occasionally cause muscle-related side effects, such as weakness or fatigue. While rare, taking them together might slightly increase the chance of feeling tired or having low energy.

Why this happens

Bisoprolol is a beta-blocker used for heart rate and blood pressure, while simvastatin is a statin used for cholesterol. They are processed by different pathways in the liver and do not interfere with how the other is absorbed or removed from the body.

You can safely take these two medicines together. It is a very common combination for heart health. If you experience unusual muscle pain, tenderness, or weakness (which can be a side effect of simvastatin), or extreme tiredness, mention it to your doctor at your next check-up.

Asthma or chronic obstructive pulmonary disease (COPD)

Bisoprolol can cause your airways to narrow, making it much harder to breathe or triggering a severe asthma attack. It is usually avoided if you have a history of wheezing or asthma.

Diabetes

Bisoprolol can mask the warning signs of low blood sugar (hypoglycaemia), such as a fast heartbeat or tremors. You will need to monitor your blood sugar more closely.

Muscle pain or weakness - simvastatin

You must report any unexplained muscle pain, tenderness, or weakness to your doctor immediately. In rare cases, this can lead to serious kidney damage.

Alcohol

You should limit your alcohol intake. For bisoprolol, alcohol can increase the blood-pressure-lowering effect, making you feel dizzy or lightheaded. For simvastatin, regular heavy drinking increases the risk of liver problems and muscle side effects.

Grapefruit juice

Avoid drinking large amounts of grapefruit juice. Grapefruit contains a chemical that increases the amount of simvastatin in your bloodstream, which significantly raises the risk of serious side effects, such as muscle damage (myopathy). It is safest to avoid it altogether.
