Patient picks for Drug interactions
Treatment and medication
Can I take Desmopressin and Ketoconazole together?
Taking these two medicines together can significantly increase the amount of desmopressin in your blood. This can lead to your body holding onto too much water, which can cause a dangerous drop in your blood salt levels (hyponatraemia). Symptoms to watch for include severe headache, nausea, vomiting, confusion, or feeling very drowsy.
Treatment and medication
Can I take Empagliflozin and Mirtazapine together?
There is no direct interaction between empagliflozin and mirtazapine. However, both medications can occasionally cause a drop in blood pressure when you stand up (postural hypotension). Taking them together might slightly increase the risk of feeling dizzy or light-headed.
