Need a little more information..however in general several things to consider...
1.) did it level out and now more is needed..for example sometimes 50mg works in first few weeks and then great effect levels off and so an increase would be in order (assuming no side effects)
2.) was there a change in generic manufacturers by any chance if been on medicine awhile I would check this information out
3.) is this the right medicine for your symptoms ... Discuss thoroughly with your doctor..I love it when patients come in with a list if info and questions for me
4)has there been an addition of a new medicine that may have interacted to lower your medicines efficacy
*** Hope this helps.
..always consult your health care provider and don't just stop your medication!
