I've had a headache and dizziness for almost 3 weeks now. been on zoloft (sertraline) for over a year. could it be causing my headache?

DEPENDS: It could contribute to headaches but unlikely if it has recently happened and you have been on the medication for 1 year. Need to see if there has been a dose change or a new generic where you may have a reaction to a different filler. Need more information and would speak with your own physician.

Must see your Dr now: Zoloft (sertraline) would be unlikely to be the cause of headaches and dizziness if you've taken it for the past year without a problem. However, Zoloft (sertraline) can uncommonly cause a mineral imbalance causing your serum sodium to fall too low (hyponatremia). This can cause similar symptoms. Anyone with a headache lasting more than several days should consult with a physician. A headache lasting 3 wks >>urgent visit
