Antibiotic Stewardship Advisor
Nigeria STG 2022-aligned antibiotic recommendations by infection, filtered by pregnancy, allergy, and renal function, with AMR warnings.
This tool recommends an antibiotic regimen for a specific infection, then automatically adjusts that recommendation for pregnancy, penicillin allergy, and renal impairment — rather than giving you one fixed answer per infection. See How Calculator Tools Work for the shared layout.
Step 1 — Pick an infection
Infections are organised into 6 categories: Respiratory, Urinary, Skin & Soft Tissue, Gastrointestinal, STIs, and Other. Search by name or browse by category.
For community-acquired pneumonia specifically, arriving here with a CURB-65 score auto-selects the right severity tier (mild/moderate/severe CAP) instead of asking you to judge it separately.
Step 2 — Patient factors
- Sex
- Pregnant (and trimester, if so)
- Penicillin allergy
- Recent antibiotics (within the last 3 months)
- CrCl (optional)
How the recommendation is filtered
The advisor starts from the infection's first-line regimen, then applies filters in this order:
- Pregnancy — if the standard first-line isn't pregnancy-safe and a pregnancy-safe alternative exists, it switches automatically, with a warning that the standard first-line isn't recommended in pregnancy. First trimester adds an extra note to verify safety and avoid doxycycline, fluoroquinolones, and metronidazole.
- Penicillin allergy — if you haven't already switched for pregnancy, and an allergy alternative exists, it switches to that, with a warning explaining why.
- Renal function — if the currently-recommended drug has a renal caution and the patient's CrCl is below that drug's threshold, the tool warns you and, if a second-line option exists, switches to it automatically.
- Recent antibiotics — always shown as a warning, not a regimen change: recent antibiotic use raises resistance risk, and the tool suggests sending a culture sample before starting treatment.
What the result shows
The recommended drug, dose, frequency, duration, and route; which of the four regimen types it is (first-line, second-line, allergy-alternative, or pregnancy-alternative); a stewardship message specific to that infection; and — where relevant — an explicit AMR (antimicrobial resistance) warning.
An AMR warning on a result isn't a suggestion — it means local resistance patterns make that regimen's effectiveness less certain for this infection. Read it before prescribing, don't skip past it to the dose.
