How should this medication be given?

For this medication to work, give it exactly as your veterinarian has prescribed. It’s a good idea to always check the prescription label to be sure you are giving the drug correctly.

  • This drug must be shaken well before use.
  • Administer this drug to your animal’s eye in the exact amount that your veterinarian has prescribed.
  • Wash your hands before administering this medication.
  • Do not touch the dropper tip or allow it to touch your animal’s eye or any other surface to prevent contamination.
  • If any residue is left on your animal’s face after giving the eye drops, gently wipe it off with a damp cloth or tissue.
  • If you are administering more than one eye medication to your animal, wait 5 minutes between each medication before giving the next one. Use eye drops before eye ointments to allow the drops to absorb into the eye.
  • If you are using this medication as an eye solution for your horse, your veterinarian may have implanted a special eye catheter (subpalpebral lavage or SPL catheter). Use this catheter exactly as your veterinarian has prescribed and only use air to flush the medications to the eye after injecting into the catheter.
  • If you are having difficulty applying the medication or your animal does not accept the treatment, contact your veterinarian or pharmacist for tips to help with administration and reducing the stress of medication time.
  • This medication can be given for various lengths of time. Be sure you understand how long the veterinarian wants you to continue giving this medication. Prescription refills may be necessary before the therapy will be complete. Before stopping this medication, talk to your veterinarian, as there may be important reasons to continue its use.

What should I do if I miss giving a dose of this medication?

If you miss a dose, give it when you remember, but if it is close to the time for the next dose, skip the dose you missed and give it at the next scheduled time. After that, return to the regular dosing schedule. Do not double-up or give extra doses.

How should I store this medication?

  • Store this medication in the original prescription bottle or an approved dosage reminder container at room temperature and protected from light.
  • If your veterinarian or pharmacist has made (compounded) a special formulation for your animal, follow the storage recommendations and expiration date for the product.
  • Keep away from children and other animals.

Can handling this medication be hazardous to me, my family, or other animals?

There are no specific precautions required when handling this medication unless you are allergic to it or other drugs like it (eg, dexamethasone), but it is always a good idea to wash your hands after handling any medication.

How should I dispose of this medication if I don’t use it all?

  • Do not flush this medication down the toilet or wash it down the sink. If a community drug “take-back” program is available, use this option. If there is no take-back program, mix the drug with coffee grounds or cat litter (to make it undesirable to children and animals and unrecognizable to people who might go through your trash), place the mixture in a sealable plastic bag to keep it from leaking out, and throw the bag out with the regular trash.
  • Do not save leftover medication for future use or give it to others to use.
