I have been taking .4mg of tamsulosin once daily for 1 month.
How long does it stay in your system after you discontinue taking it?
Following intravenous or oral administration of an immediate-release formulation, the elimination half-life of Tamsulosin hydrochloride in plasma ranged from five to seven hours. Because of absorption rate-controlled pharmacokinetics with Tamsulosin hydrochloride capsules, the apparent half-life of Tamsulosin hydrochloride is approximately 9 to 13 hours in healthy volunteers and 14 to 15 hours in the target population.
How fast tamsulosin is cleared from your system may depend on whether you take the immediate release or controlled release preparations.
Medicine is cleared from ones system in 5.5 x elimination hours. So if we took the maximum elimination half life as 15 hours, then tamsulosin should be cleared in 82.5 (83) hours.
I see you posted your question some time ago, but I just started taking tamsulosin about three months ago and was really wondering the same thing.
I found out through my pharmacist that there is no immediate release, it only comes in controlled release and that the drug stays in your body for 5 days. It does decrease over the 5 days. I would think as with all drugs if you miss a dose do not ever double up, just continue as normal
