I was prescribed methotrexate in March of this year, and opted to take it on Saturdays. I heard and read that it could knock you about, and didn't want to be struggling to stay awake (more than usual, anyway) on working days.
Initially, I was prescribed 10mg per week, which was soon increased to 15mg, then to 20mg. I'd tentatively say it's working thus far. My arthritis pain isn't quite as bad now as it was before I started, though it's been more noticeable again the last 2-3 weeks, since the cold weather set in.
I struggled a bit with tiredness after going up to 15mg per week, but then I read that you could split the dose, eg take half the pills with lunch and half with dinner. I consulted the rheumatologist about this, and he said it's fine. It seems to have worked, even since going up to 20mg. I feel like I can be active on Sundays ; go swimming, for hikes etc with no extra tiredness from the medication.
This might not be because of splitting the dose of course, it might be just getting used to the medicine, or there could be other reasons.
Any other thoughts on when is the best day for taking methotrexate and whether or not to split the dose?
