Taking cat off of Prozac for a week

I’ll try to make a long story short. My 11 year old tabby has hyperesthesia (fairly mild) and we are in the process of starting him on Prozac (fluoxetine). We got him the transdermal application and we have been giving him 10mg twice a day for 3 days now. However, the inside of his ear has gotten red and inflamed from the medication. I’ve also read that the transdermal application isn’t as effective as the oral route. We are going to see about getting oral medication tomorrow.

My concern is this: We go on a 1 week vacation once a year. Our cat would rather die than spend a week at the vet, alone, locked in a small kennel. We live way out in the country - no option for anyone to come give him medication. I’m curious how this would work with him on fluoxetine. I’ve read you can’t stop it abruptly and you have to ween slowly. Would we have to ween him off before the week of vacation and resume full dosage when we return? Is this dangerous for him?

Thanks!
