Should i get some medicine for nausea if medicine sertraline is making me feel sick and dizzy or should i stop taking it?

Get a check up: Bruising, headache, one side numbness require a physical evaluation.. There may be other reasons for feeling sick and dizzy. A trial of stopping the medication after discussion with your doctor may also be a good idea. If necessary there are other types of anti-depressants that may not have such side effects if they are in fact side effects from this medication.
