How should I take silodosin (Rapaflo)?

Your doctor may occasionally change your dose to make sure you get the best results.
Silodosin is usually taken once daily with a meal.
Silodosin lowers blood pressure and may cause dizziness or fainting, especially when you first start taking it. Call your doctor if you have severe dizziness or feel like you might pass out.
You may feel very dizzy when you first wake up. Be careful when standing or sitting up from a lying position.
Your blood pressure and prostate will need to be checked often. Visit your doctor regularly.
Some things can cause your blood pressure to get too low. This includes vomiting, diarrhea, heavy sweating, heart disease, dialysis, a low-salt diet, or taking diuretics (water pills). Tell your doctor if you have a prolonged illness that causes diarrhea or vomiting.
