Question

Which antiemetic should be taken 1 hour prior to each dose to counteract the side effects of nausea that can occur with high doses of estrogen and progestin?

1) Ondansetron
2) Metoclopramide
3) Promethazine
4) Dexamethasone

Answer 1

The best antiemetic to take before high doses of estrogen and progestin to counteract nausea is Ondansetron, also known as Zofran.

Step-by-step explanation:

The question is asking for the appropriate antiemetic medication to counteract the side effects of nausea that can occur with high doses of estrogen and progestin. Given the options provided, the best antiemetic to take 1 hour prior to each dose of estrogen and progestin is Ondansetron.

Ondansetron, marketed under the brand name Zofran, is specifically indicated to prevent nausea and vomiting caused by chemotherapy, radiation therapy, or surgery. Its efficacy in these situations suggests it can also be effective in managing nausea caused by hormone therapies, such as high doses of estrogen and progestin used in birth control formulations or other medical treatments.
