Taking alogliptin and empagliflozin together can increase the risk of your blood sugar levels dropping too low (hypoglycaemia). While both drugs are designed to lower blood sugar, using them at the same time has an additive effect. You may also have a slightly higher risk of dehydration or urinary tract infections.

Why this happens
Both medicines work in different ways to lower blood glucose: alogliptin increases insulin production after meals, while empagliflozin helps the kidneys remove sugar through urine. Because they both lower blood sugar, their combined effect is stronger than taking either one alone.
What you should do
Back to contentsIt is common for these two medicines to be prescribed together, but you should monitor your blood sugar levels regularly as directed by your doctor. Learn to recognise the signs of low blood sugar (such as feeling shaky, sweaty, hungry, or dizzy) and always carry a quick-acting sugar source, like glucose tablets or a sugary drink. Ensure you drink plenty of water to stay hydrated.

Important precautions
Back to contentsDiabetic Ketoacidosis (DKA)
Empagliflozin can cause a serious condition called ketoacidosis even if your blood sugar levels are near normal. Seek immediate medical help if you experience nausea, vomiting, stomach pain, or fruity-smelling breath. Stop taking this medicine if you are fasting for surgery or have a severe illness.
Fournier’s gangrene - empagliflozin
Seek urgent medical attention if you experience pain, tenderness, redness, or swelling in the genital or anal area, especially if accompanied by fever or a general feeling of being unwell.
Acute Pancreatitis
Stop taking alogliptin and contact your doctor immediately if you experience severe and persistent stomach pain, which might reach through to your back, as this may be a sign of an inflamed pancreas.
Food and drink warnings
Back to contentsAlcohol
Drinking alcohol with these medicines can increase the risk of low blood sugar (hypoglycaemia) and, in the case of empagliflozin, may increase the risk of a rare but serious condition called ketoacidosis. It is best to avoid excessive alcohol consumption and never drink on an empty stomach.

Patient picks for Drug interactions

Treatment and medication
Can I take Amoxicillin and Cannabis together?
There is no known direct interaction between amoxicillin and cannabis. However, using cannabis while you have an infection may make you feel more dizzy or drowsy, and smoking it can irritate your lungs, potentially slowing down your recovery from respiratory infections.

Treatment and medication
Can I take Amlodipine and Simvastatin together?
Taking these two medicines together can increase the amount of simvastatin in your blood. This makes you more likely to experience side effects, particularly muscle pain, tenderness, or weakness (a condition called myopathy). In rare cases, this can lead to a serious condition called rhabdomyolysis, which can cause kidney damage.
