Yes. Gentamicin is the generic name for the medication. The original brand-name product is called Garamycin. The generic version is manufactured by several companies, including Baxter International Inc. and Pfizer Inc.

Gentamicin is a prescription antibiotic from the aminoglycoside class, prescribed for serious bacterial infections. It is administered as an injectable solution, typically into a vein or muscle every eight hours. Your doctor determines the precise dose based on your condition, weight, kidney function, and other medications. It's crucial to complete the full course of treatment, even if symptoms improve, to prevent the infection from returning. If self-administering at home, follow your healthcare provider's instructions carefully and inspect the solution for particles or discoloration before use.

Common side effects can include nausea, vomiting, stomach upset, or loss of appetite. Pain or redness at the injection site may also occur. While many people tolerate the medication well, rare but serious side effects require immediate medical attention. These include symptoms of a severe intestinal infection (C. diff-associated diarrhea), such as persistent diarrhea, abdominal pain, cramping, or blood/mucus in stool. This condition can occur during or after treatment. Always discuss the full risks and benefits with your doctor, as this is not an exhaustive list of possible reactions.
