Patients who request a dose increase ought to be delivered with their prescribed dose and referred on the prescribing medical professional for evaluate.
If blended, monitor for QTc interval prolongation and ventricular arrhythmias. Patients with further risk factors for QTc prolongation may very well be at even increased hazard. Consider therapy modification

Other components of the strategy consist of distributing condoms and bleach (for cleaning used needles and syringes) in prison and offering absolutely free antiretroviral treatment for HIV-positive prisoners.
