Thank you for your question.
I am Dr Saha, I shall try my best to help you.
Taking hydrocodone, benadryl, lamictal & zoloft together can increase drowsiness, dizziness.
There can be lack of concentration, judgement.
If your doctor has prescribed all the medicines, then it may be OK.
If you have a person at hand, he can observe you for any excess sedation, breathing problem.
I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.
