I just had a severe reaction to bupropion hcl 300mg which required a visit to emergency room. i only took 1. should i just stop taking it?

Bupropion AE: You don't mention what the reaction was or what you were prescribed bupropion to treat (smoking cessation? -- usually is XL 150mg. Depression?), or what the adverse effect you experienced was. Check the instructions provided to you by the ER. They should indicate what meds to stop or continue, and when you should see ur prescribing doc. If you can't find these, ring the ER & your doc. Be Well!
