Taking amlodipine and aspirin together is generally considered safe, but there is a small chance that aspirin could slightly reduce how well amlodipine works to lower your blood pressure. Additionally, both medications can independently increase the risk of stomach irritation or bruising, though this is rarely a significant problem at standard doses.
Why this happens
Aspirin belongs to a group of medicines called NSAIDs. These can sometimes cause the body to hold onto salt and water, and they can interfere with natural chemicals called prostaglandins that help keep blood vessels relaxed. This can slightly counteract the blood-pressure-lowering effect of amlodipine.
What you should do
You can usually take these two medicines together. However, you should monitor your blood pressure regularly to ensure it stays within the target range set by your doctor. If you notice your blood pressure rising or if you experience unusual bruising or stomach pain, speak to your GP or pharmacist.
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 severe, life-threatening asthma attack.
Stomach ulcers or bleeding disorders
Avoid aspirin if you have an active stomach ulcer or a history of bleeding problems, as it significantly increases the risk of serious internal bleeding.
Food and drink warnings
Grapefruit juice
Grapefruit juice can increase the amount of amlodipine in your body and may cause your blood pressure to drop too low. It is best to avoid drinking large amounts of grapefruit juice while taking this medicine.
Alcohol
Drinking alcohol while taking aspirin can increase the risk of irritation and bleeding in your stomach. It is best to limit alcohol intake or avoid it if you have a sensitive stomach.

Can I take Magnesium and Wegovy flextouch together?
There is no known direct interaction between magnesium supplements and Wegovy (semaglutide). However, both can affect your digestive system. Wegovy slows down how quickly your stomach empties, which could theoretically change how quickly your body absorbs magnesium, though this is rarely a clinical concern. Additionally, both can cause side effects like nausea or changes in bowel habits (magnesium often softens stools, while Wegovy can cause constipation or diarrhoea).

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.
