Can I take Pregabalin and Venlafaxine together?

Drug interaction guide

Taking pregabalin and venlafaxine together can increase the risk of side effects that affect your central nervous system. You may feel more drowsy, dizzy, or sleepy than usual. It can also lead to difficulty concentrating, confusion, and a higher risk of falls, especially in older adults. In rare cases, it may cause breathing difficulties.

Why this happens

Both medications have 'depressant' effects on the central nervous system. While they work in different ways, their sedative effects add together (an additive effect), making the overall impact on your alertness and coordination much stronger than if you took either medicine alone.

What you should do

You should use caution when taking these two medicines together. Avoid driving or operating heavy machinery until you know how this combination affects you. It is best to avoid alcohol, as it will make the drowsiness much worse. If you experience extreme sleepiness, confusion, or shallow breathing, contact your doctor immediately.
