Name: Cetamide

What special precautions should I follow?

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.

What should I know about storage and disposal of this medication?

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

What other information should I know?

Keep all appointments with your doctor.

Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.

If you still have symptoms of infection after you finish the sulfacetamide, call your doctor.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
