How much does Gentamicin Sulfate (Gentamicin Sulfate) cost in Canada?
Canadian pharmacy listings in our data show Gentamicin Sulfate priced from about $3.29 per tablet (converted to USD), before shipping. Pack size and pharmacy both affect the final total — see the Canada pricing table for specifics.
Why does Gentamicin Sulfate (Gentamicin Sulfate) cost more in one country than the other?
Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.
Is there a brand-name version of the antibiotic Gentamicin?
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.
What is Gentamicin, and how is it used?
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.
What side effects are associated with Gentamicin?
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.
