Dosage and how to take sotalol
Dosage
Sotalol tablets come in different strengths: 40mg, 80mg and 160mg.
The usual dose of sotalol is between 80mg and 320mg a day. If you get irregular heartbeats several times a day, your doctor may prescribe a higher daily dose of up to 640mg.
If you're older or have kidney problems, your doctor may prescribe a lower dose.
How to take it
You can take sotalol with or without food, but it's best to take it the same way each day.
Swallow the tablets whole with a drink of water.
You'll usually take sotalol once or twice a day.
Your doctor may advise you to take your first dose before bedtime, because it can make you feel dizzy. After the first dose, if you do not feel dizzy, you can take sotalol in the morning.
If you take sotalol twice a day, try to take it in the morning and in the evening.
