Did you check around her mouth and nose?
I’m pasting this relevant part out of a Petco 1st aide article for rabbits. You may be in the clear with her but these are some things to watch for. Hope it helps.
Poisoning
Symptoms: Diarrhea; seizures, drooling or foaming at the mouth; swollen or red skin, ulcers in the mouth; burned lips, mouth or skin; bleeding from anus or other body cavity; abnormal mental state
Possible Causes: Accidental ingestion of poison or poisonous plant, eating toxic food or garbage, improper medication administration
What to Do: Ingested poisons:
1. Check for breathing and pulse.
2. Check the color of your rabbit’s gums. Certain poisons can cause specific changes in color.
3. Push lightly on the rabbit’s gums and see how fast they turn from pink to white and then pink again. They should turn pink again in one to two seconds. Less than one second or more than three constitutes an emergency situation.
4. Check the rabbit’s mental state.
5. Call your veterinarian or the National Animal Poison Control Center 1-800-548-2423.
Topical poisoning:
1. Call your veterinarian or the National Animal Poison Control Center 1-800-548-2423.
2. Wash your rabbit repeatedly with soap and water.
3. Flush the eyes with large volumes of tap water or sterile eyewash.
4. If the poison is in powder form, dust or vacuum it off.
Inhaled poisons (carbon monoxide and other gases):
1. Remove the animal from the area and into fresh air.
2. Check for breathing and pulse.
3. Check for and treat shock.
When to Call the Veterinarian or transport to a Veterinary Hospital: Transport immediately
