Answer 1

Hello buddy..

As per as knowledge of mine in case of Rabies or Overdose of drugs mouth often foam

Some drug overdoses can be treated with an injection of narcan.Epileptic seizures can be treated with antiepileptic medication...

I would suggest to immediately contact Doctor in such cases...

Hope it helps you buddy
