Methotrexate for psoriasis dosing must be obeyed.

Maybe they should do one pill with the correct dose, blister packed with 'week one' etc on.

That's to easy for them TL.  

But then again I suppose as it's such a cheap drug it would put the cost up as there are different dosing regimes.

I asked why each tablet was such a low dose as there were larger 25mg tablets available and was told that would cause problems and make it easier to overdose by taking 6 of the 25mg rather than 6 of the 5mg

That's a silly argument for them to come back with, why would you take 6 of them if you had one 25mg tablet on its own in a blister pack that says 'one a week'?

After all, things like blood pressure tablets are manufactured in different dose levels but you don't see people being given them in little bottles and being asked to take several if they are on a higher dose - they are one a day at whatever dose you are on.

Mtx could be one a week, of whatever dose you take. I believe loose tablets in little bottles carry more risk of misunderstanding and overdose.
