A 65-year-old male asked:

Is there much difference between 0.4 and 0.8 of tamsulosin (flomax) - find the 0.4 has lost its effect on me?

Twice as much: Taking twice the dose of tamsulosin can make a fair amount of difference for some people, but often it just increases the amount of lightheadedness (orthostatic hypotension). If 0.4mg has lost its effect, it's worth trying the double dose. If it doesn't work, see your urologist to discuss other options.
