G-Myticin is for external use only and should not be swallowed or applied to the eyes.

• Preparation: Before applying the medicine, gently wash the affected skin area with mild soap and water, and dry it thoroughly. If there are any crusts on the infected skin (common in conditions like impetigo), gently remove them as directed by your doctor. This allows the medicine to penetrate the infection more easily.
• Application: Apply a small amount of G-Myticin cream or ointment to the affected area. Rub it in gently until it is evenly distributed.
• Frequency: It is typically applied three to four times a day, or as directed by your doctor.
• Covering the Area: The treated area may be covered with a sterile gauze dressing if desired, especially if recommended by your doctor.
• Duration of Treatment: Use the medicine for the full prescribed time, even if your symptoms improve quickly. Stopping early can lead to the infection returning or becoming more difficult to treat.
• Missed Dose: If you miss a dose, apply it as soon as you remember. If it’s almost time for your next dose, skip the missed one and continue your regular schedule. Do not apply two doses at one time.

Always follow your doctor’s specific instructions for how long to use G-Myticin.

G-Myticin works by stopping the growth of certain types of bacteria that cause skin infections. As an aminoglycoside antibiotic, gentamicin interferes with the bacteria’s ability to produce essential proteins. Bacteria need these proteins to grow, multiply, and survive. Specifically, gentamicin binds to a part of the bacterial cell called the ribosome (30S ribosomal subunit). This binding disrupts the process of protein synthesis, leading to the production of faulty or non-functional proteins. Without proper proteins, the bacteria cannot function correctly, which ultimately leads to their death or prevents their further multiplication. By directly applying G-Myticin to the infected area, the antibiotic can reach high concentrations where the bacteria are, effectively fighting the infection.

• G-Myticin stops bacterial growth by interfering with protein production.
• It binds to the 30S ribosomal subunit in bacteria.
• This disrupts protein synthesis, making bacteria unable to function.

While G-Myticin is generally well-tolerated when used topically, some side effects can occur. Most are mild and localized to the application site:

• Common Side Effects:
  • Itching at the application site.
  • Skin redness or irritation.
  • Mild burning or stinging sensation.
• Less Common/More Serious Side Effects (seek medical attention if you experience these):
  • Signs of a new skin infection: Swelling, warmth, increased redness, or oozing that gets worse instead of better. This could indicate the original infection is not responding, or a new infection (e.g., fungal) has developed.
  • Signs of an allergic reaction: Hives, severe itching, difficulty breathing, or swelling of your face, lips, tongue, or throat. These are rare but require immediate medical help.
  • Prolonged use leading to superinfection: Long-term or overuse of any antibiotic can sometimes lead to an overgrowth of other organisms, like fungi, causing a new infection (superinfection).

If you experience any unusual or worsening symptoms, stop using the medication and contact your doctor.

It is important to be aware of the following warnings and precautions when using G-Myticin:

• Allergies: Do not use G-Myticin if you are allergic to gentamicin or any other aminoglycoside antibiotics.
• Prolonged Use: Avoid using G-Myticin for excessively long periods. Prolonged use can lead to the growth of non-susceptible bacteria or fungi (superinfection) or may increase the chance of systemic absorption and associated risks.
• Not for Viral or Fungal Infections: G-Myticin is an antibiotic and is only effective against bacterial infections. It will not work for infections caused by viruses (like cold sores) or fungi (like athlete’s foot).
• Open Wounds/Large Areas: While used for infected cuts, applying it to very large or severely damaged skin areas (like extensive burns) might increase the amount of gentamicin absorbed into the body, potentially leading to systemic side effects like kidney damage or hearing problems (though this is extremely rare with typical topical use).
• Eyes and Mucous Membranes: Avoid contact with eyes, nose, mouth, or other mucous membranes. If contact occurs, rinse thoroughly with water.
• Pregnancy and Breastfeeding: Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding. While topical absorption is minimal, systemic gentamicin can affect a baby. Your doctor will weigh the benefits and risks.
• Children: The safety and effectiveness of G-Myticin in children younger than 1 year have not been established.

Since G-Myticin is a topical medication, meaning it’s applied only to the skin, the amount of the active ingredient (gentamicin) that gets absorbed into the bloodstream is usually very low. Because of this, serious interactions with other medications taken by mouth or injection are generally uncommon. However, it’s still important to tell your doctor or pharmacist about all the medicines you are using, including:

• Other topical medications: Using multiple creams or ointments on the same area might affect how well G-Myticin works or could increase skin irritation.
• Aminoglycoside antibiotics: If you are also receiving other forms of gentamicin or similar antibiotics (like tobramycin or amikacin) by injection or intravenously, there’s a very slight theoretical risk of increased side effects, though this is rare with topical use.
• Nephrotoxic or ototoxic drugs: In extremely rare cases of significant absorption, drugs that can harm the kidneys (nephrotoxic) or ears (ototoxic) might have additive effects.

Always provide a complete list of your medications to your healthcare provider, even topical ones, to ensure safe and effective treatment.

The dosage of G-Myticin is generally straightforward due to its topical nature:

• Adults and Children (1 year of age and older): Apply a small amount of cream or ointment to the affected skin area three to four times a day.
• Duration: The duration of treatment will depend on the type and severity of the infection, and your response to the medication. It’s crucial to use it for the full course prescribed by your doctor, even if symptoms improve, to ensure the infection is completely cleared.
• Max Dose/Duration: There isn’t a strict “maximum dose” in the same way as oral medications, but your doctor will advise on the maximum duration of use (e.g., typically not more than 7-10 days for common infections) to prevent resistance or superinfection.
• Monitoring: Your doctor may want to re-evaluate the infection if there is no improvement after a few days of treatment.

Always follow your doctor’s instructions precisely regarding the frequency and duration of application.

G-Myticin is a prescription-only medication (POM). It is not available over-the-counter. Due to the need for proper diagnosis of a bacterial skin infection and to ensure appropriate use of antibiotics (to prevent antibiotic resistance and manage potential side effects), G-Myticin must be prescribed by a licensed medical doctor. Your doctor will assess your skin condition to confirm it’s a bacterial infection and determine if G-Myticin is the most suitable treatment. While topical, it’s still an antibiotic and should be used judiciously under medical supervision.
