Can I take Amlodopine and Rybelsus together?

Drug interaction guide

Taking Rybelsus (semaglutide) alongside amlodipine may occasionally lead to a further drop in blood pressure. While Rybelsus is primarily for blood sugar, it can sometimes cause a slight reduction in blood pressure or a small increase in heart rate. When combined with a blood pressure medicine like amlodipine, you might feel slightly more dizzy or lightheaded, especially when standing up quickly.

Why this happens

Amlodipine works by relaxing blood vessels to lower blood pressure. Rybelsus (a GLP-1 receptor agonist) can have mild effects on the cardiovascular system, including lowering blood pressure and increasing heart rate. Together, these effects can be additive, meaning they might lower your blood pressure more than either drug would on its own.

What you should do

You can take these medicines together, but you should monitor your blood pressure regularly at home. If you feel dizzy, lightheaded, or faint, sit or lie down until the feeling passes. Mention these symptoms to your doctor, as they may wish to adjust your amlodipine dose. Always stay well-hydrated, as Rybelsus can sometimes cause nausea or vomiting which can lead to dehydration and further lower your blood pressure.
