Pharmacist tips for Neo-Polycin

pharmacist
  • Make sure to follow your prescriber's instructions before using Neo-Polycin. Doing so can help you use this medication safely.
  • Depending on how serious your infection is, your eye specialist will prescribe Neo-Polycin to you for 7 to 10 days. Don't stop using it before you complete treatment, even if your symptoms get better. If you stop using Neo-Polycin too soon, your infection might come back or become harder to treat.
  • Don't let the tip of the Neo-Polycin tube touch the eye, eyelid, fingers, or other surfaces. Doing so can spread germs to the medication and cause serious harm to the eye, such as infection and vision loss.
  • Neo-Polycin, like other eye ointments, can temporarily blur your vision. Don't drive a car or operate machinery until you know how this medication affects your vision and until you can see clearly.
  • Your eye specialist will likely ask you stop wearing contact lens while you're using Neo-Polycin, until your eye infection is treated. Sometimes, eye infections are caused by contact lenses. Your prescriber will let you know when it's safe to wear contacts again.
  • To prevent new or worsening bacterial eye infections, wash your hands with soap and water often, as well as before and after using Neo-Polycin.
  • While you're using Neo-Polycin to treat your infection, don't share personal items, like pillows, towels, and eye drops, with other people. This can help prevent spreading the infection to others.

Risks and warnings for Neo-Polycin

Neo-Polycin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Only use on eye surface

Neo-Polycin should only be used on the surface of the eye. Don't put Neo-Polycin in your mouth, nose, or other parts of your body.

Allergic reaction

Tell your healthcare team before using Neo-Polycin if you have a history of allergy to antibiotics, such as gentamicin (Gentak), streptomycin, and paromomycin. Watch out for signs and symptoms of allergic reactions, such as swelling, rash, itchy skin, or other skin conditions. Please stop using Neo-Polycin and tell your care team if you have these signs and symptoms.

New or worsened eye infections

  • Risk factors: Using Neo-Polycin longer than prescribed

Using Neo-Polycin long-term can raise the risk of other eye infections, such as fungal eye infections. Don't use Neo-Polycin if you have a viral eye infection because it can make your infection worse. Let your healthcare team know if you have eye pain or redness, blurry vision, light sensitivity, or watery discharge from your eye, or if your symptoms don't improve after a couple days of treatment. These can be signs and symptoms of a new eye infection.
