I think you may have found information on aminoglycoside antibiotics in general - I cannot find any reports of topical ophthalmic tobramycin causing either kidney disease or calcium chelation in veterinary patients. Aminoglycoside antibiotics might cause these side effects when taken orally or given injectably.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Unfortunately no. :( Tobramycin is an antibiotic eye drop. Anything that contains an antibiotic requires a prescription. Also when it comes to eyes we have to very careful with what we prescribe, making sure it is safe for the eye and the condition being treated. If the kittens are having eye issues it’s best to have them seen to obtain a prescription. Good luck!

This sign could be compatible with an upper respiratory tract inflammation/infection or eventually to a chronic rhinitis (inflammatory, allergic, infective). Often viral diseases are responsible for it in cats. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed; yes Tobrex can be used for 3 days twice daily on both eyes but it is unlikely to resolve the problem. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Tobramycin is an antibiotic. It will not help to alleviate itching or swelling. You will need to call your vet to get something for that - there is nothing over the counter you can put in the eyes for this. So sorry. The best you can do is use a cool/cold compress on the eyes which should help some - 5 minutes at a time if he will let you. Do this every few hours until you can talk to your vet.

The dexamethasone steroid in Tobradex could worsen the eye condition if Habla also has a corneal scratch or ulceration. Tobramycin opththalmic antibiotic drops without the dex would be much better to give three times a day for 7 days if you are not able to take her to a vet for a fluorescein stain to rule out a corneal scratch or ulcer. If the eyes are swollen because of conjunctivitis (a bacterial eye infection) and especially if there is also ocular discharge, Apisal or Refresh saline drops alone will likely not clear the infection. Good luck!
