Conditions treated by gentamicin
Gentamicin is an antibiotic medication that is commonly used to treat various bacterial infections. It belongs to a class of drugs called aminoglycoside antibiotics that work by interfering with the growth and reproduction of bacteria. Gentamicin is primarily used to treat serious infections caused by bacteria that are resistant to other antibiotics. It is particularly effective against gram-negative bacteria, including strains of Escherichia coli and Pseudomonas aeruginosa. Some of the common infections that gentamicin is used to treat include:
- Gentamicin is often prescribed to treat severe cases of urinary tract infections (UTIs) caused by multidrug-resistant bacteria
- It can be used to treat pneumonia, bronchitis, and other respiratory infections caused by susceptible bacteria
- Gentamicin may be used to treat skin infections, such as cellulitis, caused by certain bacteria
- It can be administered intravenously to treat serious bloodstream infections, including sepsis, caused by susceptible bacteria
- Gentamicin can be used as a part of combination therapy to treat bone and joint infections caused by bacteria
- It may be used in combination with other antibiotics to treat infective endocarditis, an infection of the inner lining of the heart gentamicin is not effective against all types of bacteria and should only be used to. It is not effective against viral infections, such as the common cold or flu
How does gentamicin work?
Gentamicin exerts its mechanism of action by inhibiting protein synthesis in bacterial cells. It specifically targets aerobic bacteria, including gram-negative bacteria and acts synergistically against certain gram-positive organisms such as Staphylococcus. Once inside the bacterial cell, gentamicin binds to the 30S ribosomal subunit, which prevents the formation of functional ribosomes. This leads to the inhibition of protein synthesis and ultimately disrupts vital cellular processes necessary for bacterial survival. By interfering with protein synthesis, gentamicin disrupts essential functions within bacterial cells, preventing their growth and proliferation. This makes it effective in treating various infections caused by susceptible bacteria.
Forms of gentamicin available
Gentamicin is available in different forms, including intravenous (IV) injection, topical ointment, and eye/ear drops. The specific form and strength of gentamicin prescribed may depend on the type and severity of the infection. It is important to follow the prescribed dosage and complete the full course of treatment, even if symptoms improve. Regular monitoring may be required to ensure optimal dosing, especially in patients with renal impairment.
Dosage of gentamicin
The dosage of gentamicin may vary depending on various factors, including the type of infection, the patient’s age, and kidney function. It is important to follow the dosage instructions provided by the healthcare provider and complete the full course of treatment.
Directions for gentamicin use
The administration and duration of gentamicin treatment may vary depending on the type and location of the infection. It is important to follow the specific instructions provided by the healthcare provider or the product label.

It is important to inform your healthcare provider about all medications, supplements, and herbal products you are taking to avoid potential interactions. Here are some potential drug interactions associated with gentamicin:
- Gentamicin, when used together with diuretics, such as ethacrynic acid and furosemide can increase the risk of kidney damage. It is important to monitor kidney function closely if these medications are used together
