These side effects are generally not serious and not permanent and should resolve after the medication is stopped or completed. Baseline HIV test, full blood count, liver and renal function tests will be performed to detect any pre-existing abnormality prior to treatment and can be repeated at  weeks.

There will be a follow-up visit after  weeks to repeat full blood count, liver and renal function tests as well as and a HIV test. Follow-up HIV tests are recommended at and months post exposure.
