Why is this medication prescribed?

Gentafair, also known as Gentamicin, is an antibiotic medication commonly prescribed to treat bacterial infections of the eyes, particularly conjunctivitis (pink eye) and other eye infections caused by susceptible bacteria. It belongs to the aminoglycoside class of antibiotics and works by inhibiting bacterial protein synthesis.

How should this medicine be used?

Here’s how Gentafair is typically used:

  • Wash Hands: Before applying Gentafair, wash your hands thoroughly with soap and water to prevent contamination.
  • Eye Preparation: If using the solution, tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper directly over the eye and instill the prescribed number of drops into the pocket formed by the lower eyelid. If using the eye ointment, pull down the lower eyelid and apply a small ribbon of ointment (about 1 cm) into the conjunctival sac. Close the eye gently to spread the ointment.
  • Avoid Touching: Avoid touching the dropper or tube tip to any surface, including the eye, to prevent contamination.
  • Dosage and Frequency: Use Gentafair exactly as prescribed by your healthcare provider. Typically, it is used several times a day, depending on the severity of the infection. Follow the dosage and frequency instructions provided by your doctor.
  • Continue Treatment: Even if your symptoms improve, continue using Gentafair for the full course of treatment as prescribed by your doctor. Stopping early could allow the infection to return or worsen.
  • Avoid Contact Lenses: If you wear contact lenses, remove them before applying Gentafair. You can reinsert them after about 15 minutes after using the medication, unless otherwise directed by your doctor.
  • Side Effects: While Gentafair is generally well-tolerated, some people may experience side effects such as temporary stinging or burning upon application. If you experience any severe or persistent side effects, contact your healthcare provider.
  • Storage: Store Gentafair solution and eye ointment at room temperature away from moisture and heat. Keep the container tightly closed when not in use.

It’s crucial to follow your doctor’s instructions carefully and not to use Gentafair for any other eye condition unless specifically directed by a healthcare professional. If you have any questions or concerns about how to use Gentafair, don’t hesitate to consult your doctor or pharmacist for further guidance.

Other uses for this medicine

While Gentafair is primarily used for bacterial eye infections, it may have off-label uses or be prescribed by a doctor for other conditions. Always follow your doctor’s instructions regarding medication use.

What special precautions should I follow?

Special precautions should be followed when using Gentafair. Here are some important considerations:

  • Allergies: Inform your doctor if you are allergic to gentamicin or any other medications. If you have had previous allergic reactions to aminoglycoside antibiotics, your doctor may recommend an alternative treatment.
  • Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of using Gentafair with your doctor. While it’s generally considered safe to use in pregnancy and breastfeeding, caution is advised, and your doctor will weigh the potential benefits against any risks.
  • Contact Lenses: If you wear contact lenses, remove them before using Gentafair eye drops or ointment. You can reinsert your contact lenses after about 15 minutes following the application, unless directed otherwise by your doctor.
  • Other Medications: Inform your doctor about any other medications you are taking, including over-the-counter drugs, herbal supplements, and vitamins. Certain medications may interact with Gentafair, potentially affecting its effectiveness or increasing the risk of side effects.
  • Follow Instructions: Use Gentafair exactly as prescribed by your doctor. Do not use it in larger or smaller amounts or for longer than recommended. Using it improperly can lead to treatment failure or the development of antibiotic resistance.
  • Side Effects: Be aware of possible side effects such as stinging, burning, itching, redness, or irritation in the eyes. If these symptoms persist or worsen, contact your doctor promptly.
  • Storage: Store Gentafair solution and eye ointment at room temperature away from moisture and heat. Keep the containers tightly closed when not in use.

Always consult your healthcare provider for specific instructions and advice regarding the use of Gentafair or any other medication.

What special dietary instructions should I follow?

There are typically no specific dietary restrictions associated with Gentafair (gentamicin) use. However, maintaining a balanced diet and adequate hydration can support overall health and may aid in recovery from eye infections.

What should I do if I forget a dose?

  • If you miss a dose of Gentafair, apply it as soon as you remember, unless it is almost time for your next scheduled dose.
  • If it is nearly time for your next dose, skip the missed dose and continue with your regular dosing schedule.
  • Do not double the dose to catch up. Taking extra doses can increase the risk of side effects without providing additional benefit.
