Got a yeast infection and used monistat 1 (tioconazole). inserted it about 2 hours ago and nowi have intense agonizing itching..what can i do?

Possible allergy: This may be an acute allergic reaction which might be treatable with a variety of meds, but first needs to be seen and diagnosed by a physician since without being able to examine you would only be guessing that this is the cause. Go and be seen and hope it clears up quickly.

Use Monistat 7 for all 7 days and if that doesn't work please bring this up with your Gynecologist who knows your medical history. If you don't have confidence in your Doctor see another for a second opinion.
