- Allergic Reactions: Provides relief from severe allergic symptoms, including hay fever, urticaria, and as an adjunct in treating anaphylaxis.
- Nausea and Vomiting: Used to prevent and treat nausea or vomiting associated with motion sickness or following surgery.

- Motion Sickness: Helps manage severe motion-induced nausea.
Dosage & Administration
This medication must be administered by a healthcare professional. The preferred route is deep intramuscular (IM) injection. While slow intravenous (IV) administration is sometimes used in emergencies, it carries a high risk of tissue damage if not handled correctly. Do not attempt to self-administer this injection. If you have questions about your dosage, you can contact a GoMed pharmacist for professional guidance.
