Mr. has consulted a doctor in a hospital. He has been advised tab silodosin 8 mg hs for relief of his urinary symptoms of bph. He is around 70 yrs. His liver and kidney function tests normal. He is no bp and is not taking any other drug. This medicine is expensive for long term. He will stop taking it soon due to cost. His family doctor has advised him to take doxazosin instead, which is cheaper, has few side effects and is equally effective. Should he make this switch as advised by his family doctor. Is dosage schedule of doxazosin similar to silodosin - 8 mg hs as this drug is available from 1 to 8 mg strengths. Any side effects.
