Can I take Acetaminophen and Lisinopril together?

Drug interaction guide

There is no direct interaction between paracetamol (acetaminophen) and lisinopril. However, if you are taking lisinopril for high blood pressure or heart failure, you should be aware that paracetamol can sometimes slightly increase blood pressure if taken regularly at high doses. Additionally, you must be very careful with alcohol consumption when taking these medicines.

Why this happens

Paracetamol and lisinopril are processed by the body through different pathways (the liver and kidneys respectively) and do not interfere with how the other is absorbed or removed from the system. While paracetamol does not block the effects of lisinopril like some other painkillers (such as ibuprofen) do, long-term use of paracetamol may slightly raise blood pressure in some people.

It is generally safe to take paracetamol for short-term pain relief while taking lisinopril. If you need to take paracetamol every day for a long time, you should have your blood pressure checked regularly by your GP. It is best to avoid or strictly limit alcohol while taking these medicines, as combining alcohol with paracetamol increases the risk of liver damage, and alcohol can also interfere with blood pressure control.
