Half-Life of Flomax tamsulosin hydrochloride: 9 - 13 hours.
The biological half-life or elimination half life of a substance is the time it takes for a substance (for example a metabolite, drug, signalling molecule, radioactive nuclide, or other substance) to lose half of its pharmacologic, physiologic, or radiologic activity, as per the MeSH definition. In a medical context, half-life may also describe the time it takes for the blood plasma concentration of a substance to halve ("plasma half-life") its steady-state. The relationship between the biological and plasma half-lives of a substance can be complex, due to factors including accumulation in tissues, active metabolites, and receptor interactions.

Just stated taking flomax and am having dizzy spells. Should I persevere with this drug? Flomax has reduced urgency to urinate and empties bladder.
