Please use the ondansetron in your kit up to every 6 hours for nausea. If this is not enough, you can take Benadryl (diphenhydramine) up to 50mg (2 tabs). Benadryl is available over the counter as an allergy medication and can make you very sleepy. Liquid versions of Benadryl can help if you can’t swallow the pill form. Do not use this method if you are taking antidepressants, anti-seizure medications or long term antibiotics. Do not drive or operate heavy machinery when using Benadryl.
