Can I take Losartan and Tizanidine together?

Why this happens

Both medicines have the effect of lowering blood pressure, though they do it in different ways. Losartan is specifically for blood pressure, while tizanidine is a muscle relaxant that also has a strong blood-pressure-lowering effect. When used together, their effects add up (an additive effect), which can lead to an excessive drop in blood pressure.

You should use this combination with caution. When you first start taking them together, or if your dose is increased, be careful when standing up. Move slowly to give your body time to adjust. If you feel very dizzy, faint, or unusually sleepy, contact your doctor. They may need to adjust your doses or monitor your blood pressure more closely.
