Can I take Losartan and Pregabalin together?

Drug interaction guide

Both medications can cause drowsiness, dizziness, and a drop in blood pressure. Taking them together may increase the risk of feeling lightheaded, sleepy, or unsteady on your feet, which could lead to falls. Some patients may also experience increased swelling (fluid retention) in the legs or feet.

Why this happens

This is a 'pharmacodynamic' interaction, meaning the drugs have different ways of working but produce similar side effects. Losartan lowers blood pressure, while pregabalin can cause dizziness and sedation as it affects the nervous system. When combined, these effects can add up. Additionally, both drugs are occasionally linked to peripheral oedema (fluid swelling).

What you should do

It is generally safe to take these together, but you should be cautious, especially when starting the combination or increasing the dose. Avoid driving or operating machinery until you know how the mix affects you. To prevent dizziness, try to stand up slowly from a sitting or lying position. If you notice significant swelling in your ankles or feel unusually faint, contact your doctor.
