Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

The onset time for this drug is 1-2 hours, with peak or full effect starting 2-6 hours post treatment (which is why injectable is preferable when possible). So, we'd expect to see some effects in the first few hours but it can take longer for the drug to overcome the allergic reaction. That said, if you gave cortisone this should take effect at a similar time frame.

All the best,

Dr. B.
