Post-exposure prophylaxis guidelines for children and adolescents potentially exposed to HIV.

UK guidelines for HIV post-exposure prophylaxis (PEP) in adults have recently been updated. Indications for PEP have been modified and there has been a change in the recommended antiretroviral therapy for adults to a combination of raltegravir with tenofovir and emtricitabine (Truvada). Raltegravir and tenofovir are now available in paediatric formulations and offer improved safety and tolerability over previously recommended ritonavir-boosted lopinavir with zidovudine. This guideline provides recommendations for those caring for children potentially exposed to HIV and other bloodborne viruses in primary care, emergency departments, secondary care and specialist paediatric HIV centres.
