Doses are oral and for adults unless otherwise stated. Visit the Health Products Regulatory Authority (HPRA) website for detailed drug information (summary of product characteristics and patient information leaflets). Dosing details, contraindications and drug interactions can also be found in the Irish Medicines Formulary (IMF) or other reference sources such as British National Formulary (BNF) / BNF for children (BNFC). See guidance on dosing in children for quick reference dosage/weight guide. Refer to drug interactions table for detailed drug interactions for all antimicrobials. Note extensive drug interactions for clarithromycin, fluoroquinolones, azole antifungals and rifampicin. Many antibiotics increase the risk of bleeding with anticoagulants.
Note additional warnings for clarithromycin and fluoroquinolones
Comments from Expert Advisory Committee
- If pregnant/immunocompromised seek advice. Dosing in the immunocompromised requires an extended course of antivirals.
- Chicken pox: In immunocompetent, value of antivirals minimal unless severe pain, or adult, or on steroids, or secondary household case AND treatment started within 24h of onset of rash.A-
- Shingles: Always treat if active ophthalmic infection, Ramsey Hunt or eczema.
- Non-ophthalmic shingles: Treat if >50 yrs and within 72h of onset of rash, as post-herpetic neuralgia rare in <50 yrs but occurs in 20% >50 yrsA+
