How Long Does Dizziness Due To Gabapentin And Mirtazapine Last?
A few days in most cases.
Detailed Answer:
I read your question carefully and I understand your concern regarding drug side effects.
Of course it might have been useful if you had provided some more info on dosage, frequency, duration of therapy. It is unclear whether you're using them together or are simply wondering what would happen if your did.
Anyway, dizziness might persist for a few days with Mirtazapine (if present that is, happens as a side effect in only 7% of patients) as it is eliminated more slowly from the body, so dizziness may persist for at least 2 days, depending on your metabolism even longer.
Gabapentin is eliminated more rapidly, so should be out of your body in about 24-48 hours.
I remain at your disposal for other questions.
