Hi XXXX,
Thanks for writing in to us.

I have read through your query in detail.
Please find my observations below.

1. Zofran contains ondansetron which is given to control vomiting tendency.

2. It should be taken carefully if you have any liver problem.

3. In a person of your age and gender the half elimination time of Zofran 8 mg is 3.5 hours. Therefore in about 18 hours, more than 97 percent will be out of your system.

Hope this answers your question. Please feel free to correct any oversight in my interpretation of your problems and discuss them in detail as per your requirements.

Hope your query is answered.
Do write back if you have any doubts.

1. Ondansetron contains substances that can affect your anxiety. If you have been given this medicine by your psychiatrist then please discuss your symptoms in detail.
