To use this medicine:

Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.

  • Wait at least 10 minutes before using any other eye drops your doctor has prescribed.

  • Eye ointment: Hold the ointment tube with the tip pointing toward this pocket. Look up and away from the tip. Squeeze out a ribbon of ointment into the lower eyelid pocket without touching the tip of the tube to your eye. Blink your eye gently and then keep it closed for 1 or 2 minutes.

  • Use a tissue to wipe excess ointment from your eyelashes.

  • After opening your eyes, you may have blurred vision for a short time. Avoid driving or doing anything that requires you to be able to see clearly.

Before using sulfacetamide eye drops or eye ointment,

  • tell your doctor and pharmacist if you are allergic to sulfacetamide, sulfa drugs, sulfites, or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other eye medications and vitamins.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while using sulfacetamide, call your doctor immediately.
  • you should know that your vision may be blurred during your treatment with sulfacetamide eye ointment. Avoid rubbing your eyes even if your vision is blurred. Do not drive a car or operate machinery if you are unable to see clearly.
  • tell your doctor if you wear soft contact lenses. If the brand of sulfacetamide you are using contains benzalkonium chloride, wait at least 15 minutes after using the medicine to put in soft contact lenses.

Instill or apply the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not instill or apply a double dose to make up for a missed one.

Sulfacetamide may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

  • temporary stinging or burning of the eye
  • increased redness, itching, or swelling of the eye that continues for more than 48 hours

Keep this medication in the container it came in, tightly closed, and out of the reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Do not let it freeze and do not use discolored eye drops (yellowish brown to deep reddish brown).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
