Best treatments for osteomyelitis
2 products may treat osteomyelitis, spanning FDA drug classes such as penicillin-class antibacterial. Ranked below by our independent recall-safety rating (rated where FDA data exists) — not medical advice; always consult a professional.
Quick answer: Of the 2 drugs we list for osteomyelitis, none are yet flagged as generics in our price data, spanning classes such as penicillin-class antibacterial. They’re ranked by each drug’s FDA recall-safety record — not clinical effectiveness for osteomyelitis — so confirm the right choice with your prescriber.
Understanding osteomyelitis
Osteomyelitis is an infection of the bone. According to MedlinePlus (NLM), bacteria or other germs "may spread to a bone from infected skin, muscles, or tendons next to the bone"; an infection can also "start in another part of the body and spread to the bone through the blood", or "start after bone surgery". MedlinePlus lists the usual symptoms as bone pain, fever and chills, excessive sweating, and local swelling, redness and warmth, sometimes with an open wound that may show pus. Because those signs also fit many other problems, diagnosis rests on tests rather than examination alone: MedlinePlus names blood culture, bone biopsy, bone scan, bone x-ray, complete blood count and MRI of the bone. Treatment is long by the standards of most infections — antibiotics "are taken for at least 4 to 6 weeks, often at home through an IV" — and surgery may be needed "to remove dead bone tissue" when antibiotics alone do not clear it. MedlinePlus states the outlook for acute osteomyelitis is often good with treatment, and worse in long-term chronic osteomyelitis, where "amputation may be needed, especially in people with diabetes". This is general information, not medical advice; osteomyelitis is diagnosed and treated by clinicians, and the drugs listed on this page are rated on FDA recall-safety data, not on how well they treat a bone infection.
First-line treatment
There is no single first-line drug, because the antibiotic follows the organism: MedlinePlus describes antibiotics "given to destroy the bacteria causing the infection", which means the germ has to be identified first. The clearest published protocol covers the spine. For native vertebral osteomyelitis, the 2015 IDSA guideline recommends obtaining two sets of aerobic and anaerobic blood cultures plus baseline ESR and CRP in all patients with suspected infection, and an image-guided aspiration biopsy when blood cultures have not established a microbiologic diagnosis — withholding antimicrobial therapy, in a hemodynamically stable patient, until that diagnosis exists. It then recommends "a total duration of 6 weeks of parenteral or highly bioavailable oral antimicrobial therapy for most patients", extended to 3 months for Brucella species, and recommends surgery "in patients with progressive neurologic deficits, progressive deformity, and spinal instability". That guideline is written for vertebral osteomyelitis specifically and does not automatically transfer to other sites; a clinician sets the drug, route and duration in each case.
