Make sure you drink enough water in hot weather and during exercise while you are using Frusemide Sandoz Injection, especially if you sweat a lot. If you do not drink enough water, you may feel faint, light-headed or sick. This is because your blood pressure is dropping suddenly and you are losing too much fluid. If you continue to feel unwell, contact your doctor.

Things you must not do
