Taking alogliptin and losartan together may slightly increase the risk of your blood sugar levels dropping too low (hypoglycaemia). It may also increase the risk of a rare but serious allergic reaction called angioedema (swelling of the face, lips, or throat).
Why this happens
Alogliptin helps lower blood sugar, and some blood pressure medications like losartan can occasionally enhance this effect. Additionally, both drugs can affect a system in the body that regulates swelling, which may rarely lead to an allergic-type reaction.
What you should do
It is generally safe to take these together, but you should monitor your blood sugar levels more closely, especially when starting or changing doses. Seek immediate medical help if you notice any swelling of the face, lips, or tongue, or if you have difficulty breathing.
Important precautions
Pregnancy
You must not take losartan if you are pregnant or planning to become pregnant, as it can cause serious harm or death to an unborn baby, particularly in the second and third trimesters.
Pancreatitis
Stop taking alogliptin and seek immediate medical help if you experience severe and persistent stomach pain, which may reach through to your back, as this can be a sign of an inflamed pancreas (pancreatitis).
High potassium levels (Hyperkalaemia)
Avoid using salt substitutes containing potassium or taking potassium supplements while on losartan, as it can cause dangerously high levels of potassium in your blood.
Food and drink warnings
Alcohol
Drinking alcohol while taking losartan can increase the blood-pressure-lowering effect of the medicine. This may make you feel dizzy, lightheaded, or faint, especially when standing up. It is best to keep your alcohol intake within recommended limits and be cautious until you know how the medicine affects you.
Salt substitutes and high-potassium foods
Losartan can increase the levels of potassium in your blood. Using salt substitutes (which often contain potassium chloride) or consuming very large amounts of potassium-rich foods (such as bananas or leafy greens) may lead to dangerously high potassium levels (hyperkalaemia). You do not need to avoid these foods entirely, but you should avoid using potassium-based salt substitutes.

Can I take Warfarin and Aspirin together?
Taking warfarin and aspirin together significantly increases your risk of serious bleeding. This includes internal bleeding, such as in the stomach or brain, as well as bleeding that is hard to stop from minor cuts or injuries.

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).
