How to Take (Kaise leni hai)

  • Take WITH food
  • Swallow the capsule whole — do not open it
  • With plain water
  • Same time every day — to maintain a routine
  • First dose with the evening meal — reduces hypotension risk

Best Time to Take (Kab leni chahiye)

  • With the evening meal — orthostatic hypotension risk is minimised
  • Or with the morning meal — as per the doctor's advice

With Food or Empty Stomach (Khali pait ya khane ke baad)

Take WITH food — this is essential. Food reduces the peak concentration of silodosin — side effects (dizziness, GI) are better tolerated.

Missed Dose (Dose chhoot jaye to kya karein)

Take as soon as you remember. If the next dose is near, skip it — continue on schedule. Never take a double dose.

Overdose (Zyada Dose)

Silodosin overdose may cause severe BP drop (hypotension), fainting, and rapid heartbeat. Contact a doctor or emergency room immediately.

Frequently Asked Questions

Silodosin ki standard dose kya hai?

Standard adult dose is 8mg once daily — take with food. In renal impairment, reduce dose to 4mg once daily (eGFR 30–50 mL/min). Avoid in severe renal impairment.

Silodosin khane ke sath leni chahiye ya baghair?

Take WITH food — food reduces the peak blood level of silodosin and decreases stomach/GI side effects. Do not take on an empty stomach.

Pehli baar lena shuru karein to kya karna chahiye?

Take the first dose with the evening meal — lying down afterwards reduces the risk of orthostatic hypotension. Rise slowly from bed in the morning.

Kya silodosin ki dose kidney problem mein adjust hoti hai?

Yes — at eGFR 30–50 mL/min, reduce the dose to 4mg once daily. Do not take at all with eGFR < 30. The doctor will monitor kidney function.

Silodosin kitne waqt tak leni hai?

BPH is generally a lifelong condition. The doctor will decide on dose and duration at regular follow-up visits.
