Teicoplanin Dose Calculator
✓ IM administration possible (vancomycin: IV only)
✓ Once-daily after loading (vancomycin: BD–TDS)
✓ No Red Man Syndrome infusion requirement
✓ Less nephrotoxic than vancomycin
✗ More expensive than vancomycin
⚠️ Adequate loading critical — subtherapeutic troughs common if loading omitted
CrCl >40: Standard OD
CrCl 10–40: Every 48h (alternate day)
CrCl <10 / dialysis: Every 72h — TDM essential
⚠️ Loading doses unchanged regardless of renal function
Teicoplanin — Clinical Guide India
Teicoplanin (Targocid) is a glycopeptide antibiotic with the same spectrum of activity as vancomycin — covering Gram-positive organisms including MRSA, coagulase-negative staphylococci (CoNS), enterococci, and streptococci. Its major pharmacokinetic advantage is an extremely long half-life (70–100 hours), enabling once-daily dosing after an initial loading phase, and its ability to be given by intramuscular injection — a significant practical advantage in settings where maintaining IV access is challenging. Unlike vancomycin, teicoplanin does not cause Red Man Syndrome and does not require slow infusion or rate monitoring.
Loading doses — the most important clinical point
Teicoplanin's very long half-life means it takes weeks to reach steady state without a loading dose. The loading regimen (3 doses every 12 hours) is essential — omitting or underdosing the loading phase leads to subtherapeutic trough levels for days, significantly increasing treatment failure rates, particularly for endocarditis and MRSA bacteraemia. Standard loading: 6 mg/kg IV or IM every 12 hours for 3 doses (doses at 0h, 12h, 24h). For severe infections (endocarditis, bacteraemia): increase to 12 mg/kg for loading doses. After loading, maintenance begins: 6 mg/kg once daily (or 6–12 mg/kg OD for severe infections).
TDM — trough levels and target
TDM is mandatory for teicoplanin. Trough levels should be drawn just before the 4th or 5th maintenance dose (steady state). Target trough: ≥10 mg/L for moderate infections (skin, soft tissue); ≥15 mg/L for serious infections (bacteraemia, osteomyelitis, endocarditis — the EUCAST/BSAC recommendation). Levels below 10 mg/L are consistently associated with clinical failure in MRSA infections. If the trough is subtherapeutic, give an additional 6 mg/kg loading dose and recheck 48 hours later before adjusting maintenance.
