Is medication more effective in small doses taken over a long period or larger doses taken over a short period

Question

I have just been prescribed Betahistine Dihydrochloride for dizziness that I have had for three weeks following concussion. I have been given the option of taking either one or two 8mg tablets three times a day, with 21 in the pack, so I could take them as a larger dose over 4 days or a smaller dose to spread them over 7 days. Does anyone know which would be more beneficial? Thanks.

Answer 1

i dont know what would be best but i suffer from vertigo (dizzy) not the same thing you are going thru but my presciption says the same thing. i started taking the lower dose and didnt feel much improvement so i took the larger one instead.  so basically i took what was needed.

dont know if that will help you.  i suggest taking the lower first and seeing if you feel better.  if you still feel really dizzy then take the larger dose.

hope you feel better soon :)

Answer 2

it should be taken as prescribed by the doctor. But in my own opinion i think small doses is more effective in a given period of time than larger doses,and i think lager doses is over doses and kind of drug abuse.

  

Answer 3

Either way, you get the same amount of medication in your body. And over the timeframe you're suggesting there wouldn't be too much (if any) difference in efficiency.
