- Consider specialist referral for recurrent infection.
- Results of laboratory cultures and sensitivities usually available after overnight incubation.
- If culture results indicate sensitivity to ‘tetracycline’ then oxytetracycline (less expensive in primary care) or tetracycline should be considered. Doxycycline is inappropriate due to low renal excretion.
- In patients with CKD3 or above and/or those at risk of hyperkalaemia these agents may be unsuitable. Please check current prescribing advice as per BNF and seek specialist advice if alternative agent required.
