mad iquana disease?

Question
15 years ago our 12yr old son was given an 18" iquana. Now our son has left and we have a 48" iquana...
He has been in a cage 5' long,3'high and 2'deep for the past three tears. The cage has a sloped fiberglass bottom with a drain that holds about 3 gallons of water. He has a basking board near the top with a ramp down to a feeding level just above the water. Total veggie diet, with lotsa different coloured food from our salad supply. The cage is in the living room (with the wood stove)where he can watch TV.
We have 4' tubes on during the day with heat lamps on 24hrs. We live in central Ontario and have had the stove running for the past 6 weeks or so.(It heats the house)
About three days ago he started to have periods where he would tear around his cage, thru the water, accross the ceiling etc, running into things. As a result it looks like he has broken his nose (it starts to bleed). He eats and deficates normally, (although at this time of year he doesn't get the variety of fresh garden veggies and berries) There are no vets within 100 miles that admit to working with iquanas that we have been able to locate.
We aqre trying to find what could be setting him off and what kind of antibiotics we might give him to prevent infection.

Hi Pat,
The cage is a bit small for your igs size...which allowing him to have free roam time would benefit him greatly..
This time of year many igs are in breeding season. I'm assuming you know 100% that he is a male.  They get rather crazy during breeding season. Its normal...and yes, they can do harm to their self as you have seen. Also, human females can set them off....monthly periods, pregnancy and hormonal changes such as menopause...we get to figure out what the cause is and what we can do to help the ig through it..
You can try giving him a stuff toy...iguana sized..we call them "love Socks"
Is he able to see another animal?  That may also be setting him off..especially in breeding season.
As to antibiotics....there are none that you can give him that aren't vet prescribed.  Here are some links to finding vets that can treat reptiles.

If no luck finding one closer to you, many times a regular vet will see the reptile and consult by phone with a vet that does treat reptiles to get the recommended medications and dosages..
The most common antibiotic used on reptiles is Baytril...and its generally given for 3-4 weeks...
Also they would most likely prescribe Silvadene ointment to be applied to the injured area.
You can use Neosporin OINTMENT on the injury..which will not harm him if he licks it. Do be careful of the nostrils though.
If the Neosporin doesn't help show improvement in a few days..then you need to get in touch with a vet.
Igs take a very long time to heal...
