Patient picks for Drug interactions
Treatment and medication
Can I take Codeine and Magnesium together?
Taking magnesium and codeine together can lead to increased drowsiness and may cause constipation. Magnesium can also slightly interfere with how your body absorbs codeine if taken at the exact same time.
Treatment and medication
Can I take 150 and Zigduo together?
Taking aspirin (75mg to 150mg) with Xigduo (which contains dapagliflozin and metformin) can increase the risk of your blood sugar dropping too low (hypoglycaemia). It may also increase the risk of a rare but serious condition called lactic acidosis, where too much acid builds up in your blood.
