Can I take Bisoprolol and Rybelsus (semaglutide) together?

Drug interaction guide

Taking bisoprolol and Rybelsus (semaglutide) together can make it harder for you to notice the warning signs of low blood sugar (hypoglycaemia). Bisoprolol can hide symptoms like a fast heartbeat, palpitations, or tremors. Additionally, bisoprolol may slightly interfere with how your body manages blood sugar levels, potentially making Rybelsus less effective or, in some cases, increasing the risk of a 'hypo'.

Why this happens

Bisoprolol is a beta-blocker that works by slowing the heart rate and blocking the effects of adrenaline. Adrenaline is the hormone responsible for the 'shaky' feeling and racing heart you get when your blood sugar drops too low. By blocking these signals, the drug 'masks' the symptoms of low blood sugar. Furthermore, beta-blockers can sometimes interfere with the release of insulin and the body's ability to release stored sugar from the liver.

You can take these medicines together, but you should be extra vigilant. Since you may not feel a racing heart if your blood sugar drops, look out for other signs of a 'hypo' that bisoprolol doesn't mask, such as sweating, dizziness, hunger, or confusion. It is a good idea to monitor your blood sugar levels more frequently when starting or changing the dose of either medication. Discuss a plan with your doctor or pharmacist on what to do if your blood sugar levels become unstable.

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.

History of pancreatitis

Rybelsus increases the risk of inflamed pancreas (pancreatitis). You must stop treatment and seek urgent medical help if you develop severe, persistent stomach pain that may reach through to your back.

Alcohol

Alcohol can increase the blood-pressure-lowering effect of bisoprolol, which may make you feel dizzy or lightheaded. For Rybelsus, alcohol can affect your blood sugar levels and may increase the risk of low blood sugar (hypoglycaemia) or stomach upset.

Food and Drink (General)

You must take Rybelsus on an empty stomach with a small sip of plain water (no more than 120ml). You must wait at least 30 minutes before eating, drinking anything else, or taking other oral medicines. If you eat or drink too soon, the medicine will not be absorbed properly and will not work.
