Tazzle 20 mg is usually taken orally with water, about 30–60 minutes before sex, and should not be used more than once in 24 hours. It can be taken with or without food, and its effect lasts up to about 36 hours, giving a long window for sexual activity as long as you are aroused. For BPH‑related urinary problems, doctors may prefer a lower, daily dose rather than on‑demand 20 mg. Common side effects include headache, flushing, nasal congestion, indigestion, back or muscle pain, and mild dizziness or blurred vision.
