Taking aspirin and ramipril together can sometimes make the ramipril less effective at lowering your blood pressure. There is also a small risk that the combination could affect how well your kidneys work, especially if you are older, dehydrated, or already have kidney problems.
Why this happens
Ramipril works by relaxing blood vessels through a chemical process in the body. Aspirin (especially at higher doses) can block the production of substances called prostaglandins, which help ramipril work and also help protect the kidneys. When these are blocked, blood pressure may rise slightly and the kidneys may have to work harder.
What you should do
If you are taking low-dose aspirin (75mg to 150mg) for heart protection, it is usually fine to take with ramipril, but your doctor should still monitor your blood pressure and kidney function. Avoid taking high-dose aspirin (for pain or fever) regularly without speaking to your doctor. Ensure you stay well-hydrated and report any signs of swelling in your ankles or changes in how often you urinate.
Important precautions
Asthma
Do not take aspirin if you have a history of asthma triggered by aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), as it can cause a life-threatening asthma attack.
Pregnancy
You must not take ramipril if you are pregnant. It can cause serious injury or death to an unborn baby, particularly if taken during the second and third trimesters.
Angioedema (Swelling) - ramipril
Seek immediate medical help if you experience swelling of the face, lips, tongue, or throat. This is a rare but serious allergic reaction called angioedema that can block your airway.
Food and drink warnings
Alcohol
Drinking alcohol while taking aspirin can increase the risk of stomach irritation and bleeding. It is best to limit alcohol intake or avoid it if you have a history of stomach issues.
Salt substitutes (Potassium-enriched)
Ramipril can increase the levels of potassium in your blood. Using salt substitutes that contain potassium (such as Lo-Salt) can cause your potassium levels to become dangerously high. Check the labels of any 'low-sodium' products.

Can I take Mounjaro and Insulin together?
Taking Mounjaro (tirzepatide) and insulin together significantly increases your risk of having a 'hypo' (hypoglycaemia), which is when your blood sugar levels drop too low. Symptoms of a hypo can include feeling shaky, sweaty, dizzy, hungry, or confused. In severe cases, it can be dangerous.

Can I take Sertraline and Fluoxetine together?
Taking sertraline and fluoxetine together significantly increases the risk of a rare but serious condition called serotonin syndrome. This happens because both medicines work by increasing the level of a chemical called serotonin in your brain. If levels get too high, it can cause symptoms like shivering, diarrhoea, confusion, severe muscle tightness, fever, and even seizures. Additionally, fluoxetine can slow down how your body breaks down sertraline, leading to a build-up of the drug in your system and increasing the risk of side effects.
