It can take about 2 to 8 weeks before you start feeling better. The maximum effect can take up to 3 â 6 months. If your doctor changes the dose it can take another 6 to 8 weeks before you feel the effects.
Hi Gemz10. I think most people would say 12 weeks as this is when they would up the dose of your treatment if you need it. I have been on Methotrexate for about 18 mnths and when diagnosed I have minimal syptoms, mainly the balls of my feet, stiff fingers, and really really really really tired! was diagnosed with RA in october and have been taking methotrexate for 13 weeks now. I still have inflamation and sometimes pain/discomfort walking.
