When doctors need a reliable option for certain gram‑positive infections, Lincocin is the trade name for lincomycin, a lincosamide antibiotic that blocks bacterial protein synthesis. While the drug has been around since the 1960s, patients and clinicians still wonder how it stacks up against newer choices. This guide walks through the science, the practical pros and cons, and the most common alternatives you might encounter in a prescription.
Lincomycin binds to the 50S ribosomal subunit of susceptible bacteria, halting the elongation of peptide chains. This mechanism is especially effective against many Gram‑positive bacteria such as Staphylococcus aureus. Because it targets a site distinct from beta‑lactams, lincomycin retains activity against some strains that produce penicillin‑breaking enzymes.
In the UK, Lincocin is most often prescribed for:
Standard adult dosing is 600 mg intravenously every 8 hours, or 600 mg orally every 12 hours for milder infections. The drug’s half‑life is about 2.5 hours, so consistent dosing is key to keeping bacterial levels suppressed.
When Lincocin isn’t available or a clinician prefers a different safety profile, several antibiotics are routinely used. Below are the most relevant comparators, each introduced with its own microdata definition.
Clindamycin is a semi‑synthetic lincosamide that shares the same ribosomal target as lincomycin but offers better oral bioavailability and a longer half‑life.
Erythromycin belongs to the macrolide class; it also blocks the 50S subunit but tends to cause more gastrointestinal upset.
Azithromycin is a newer macrolide with a very long tissue half‑life, allowing once‑daily dosing for many infections.
Doxycycline is a tetracycline derivative that inhibits protein synthesis at the 30S subunit and offers broad‑spectrum coverage, including atypical organisms.
All the drugs listed can cause gastrointestinal disturbances, but the frequency and severity differ. Lincomycin (Lincocin) is notorious for a higher incidence of diarrhea, sometimes leading to C. difficile infection. Clindamycin shares this risk but is generally better tolerated when taken orally. Macrolides (erythromycin, azithromycin) often cause nausea and a metallic taste, while doxycycline can cause photosensitivity and esophageal irritation.
Price varies by formulation and pharmacy. As of October 2025:

| Attribute | Lincocin (Lincomycin) | Clindamycin | Erythromycin | Azithromycin | Doxycycline |
|---|---|---|---|---|---|
| Spectrum (primary) | Gram‑positive, anaerobes | Gram‑positive, anaerobes | Gram‑positive, some atypicals | Broad, including atypicals | Broad, including atypicals & rickettsiae |
| Oral bioavailability | ~30 % | ~90 % | ~30 % | ~50 % | ~95 % |
| Typical adult dose | 600 mg IV q8h or PO q12h | 300 mg PO q6‑8h | 250‑500 mg PO q6h | 500 mg PO q24h | 100 mg PO q12h |
| Common side effects | Diarrhea, C. difficile | Diarrhea (lower risk), nausea | Nausea, abdominal pain | GI upset, headache | Photosensitivity, esophagitis |
| Cost (UK, 2025) | £12‑£15 per vial | £8‑£10 per pack | £6‑£8 per pack | £9‑£12 per pack | £5‑£7 per pack |
| Resistance concerns | Increasing MRSA resistance | Similar MRSA trends | Macrolide‑resistant Streptococcus | Growing macrolide resistance | Tetracycline resistance in some Gram‑negatives |
Lincocin shines when you need a drug that works well against anaerobic skin infections and can be given intravenously for severe cases. However, its relatively low oral absorption and higher risk of C. difficile infection often make clinicians lean toward clindamycin or azithromycin for outpatient therapy.
When deciding whether to prescribe Lincocin or an alternative, consider these factors:
Lincocin should be avoided in patients with known hypersensitivity to lincosamides. Liver disease can impair drug metabolism, while severe renal impairment may require dose adjustment. Pregnant women are generally advised to use alternative agents unless the infection is life‑threatening, as animal studies have shown potential fetal risks.
Yes, lincomycin is available in oral tablets, but the absorption is only about 30 %, so IV administration is preferred for serious infections.
Some MRSA strains remain susceptible, but resistance has been climbing. A local antibiogram should guide use.
Both block the 50S ribosomal subunit, but clindamycin is a semi‑synthetic derivative with higher oral bioavailability and a longer half‑life, making it more convenient for outpatient therapy.
Monitor for severe diarrhea, especially if it is watery or bloody, as this may signal C. difficile infection. Also watch liver function tests in patients with hepatic disease.
Lincomycin can increase neuromuscular blocking agents’ effects and may reduce the efficacy of oral contraceptives, so discuss all meds with your prescriber.
By weighing infection severity, route of delivery, side‑effect risk, and local resistance, you can decide whether Lincocin or one of its alternatives is the better fit for your case.

Oh joy, another deep‑dive into a drug that nobody asked for. Let me just point out that Lincocin’s low oral bioavailability means you’re basically paying for an IV drip in a pill. If you love spending extra cash for a drug that gives you diarrhea, then by all means, go ahead. The half‑life of 2.5 hours also forces you into a three‑times‑daily schedule – perfect for anyone who enjoys frequent pharmacy trips. And don’t forget the C. difficile risk; nothing says ‘I’m a responsible patient’ like a gut infection.
