Can I take Aspirin and Perindopril together?

Why this happens

Perindopril (an ACE inhibitor) works by widening blood vessels and helping the kidneys remove salt and water. Aspirin can block the production of natural substances called prostaglandins, which the body uses to keep blood vessels open and protect the kidneys. By blocking these, aspirin can counteract the blood-pressure-lowering effects of perindopril and reduce blood flow to the kidneys.

If you are taking low-dose aspirin (75mg to 150mg) for heart protection, it is usually fine to take with perindopril, but your doctor should monitor your blood pressure and kidney function regularly. Avoid taking high-dose aspirin (for pain relief) regularly without speaking to your doctor. Ensure you stay well-hydrated and report any signs of kidney issues, such as changes in urination or swelling in your ankles, to your GP.
