4.2    Posology and method of administration
Therapy should be initiated by a physician experienced in the management of HIV infection.

Posology

The recommended dose of EDURANT is one 25 mg tablet taken once daily. EDURANT must be taken with a meal [see section 5.2].

Dose adjustment
For patients concomitantly receiving rifabutin, the EDURANT dose should be increased to 50 mg (two tablets of 25 mg each) taken once daily. When rifabutin co-administration is stopped, the EDURANT dose should be decreased to 25 mg once daily (see section 4.5).


Missed dose
If the patient misses a dose of EDURANT within 12 hours of the time it is usually taken, the patient must take the medicine with a meal as soon as possible and resume the normal dosing schedule. If a patient misses a dose of EDURANT by more than 12 hours, the patient should not take the missed dose, but resume the usual dosing schedule.

If a patient vomits within 4 hours of taking the medicine, another EDURANT tablet should be taken with a meal. If a patient vomits more than 4 hours after taking the medicine, the patient does not need to take another dose of EDURANT until the next regularly scheduled dose.
Special populations

Elderly
There is limited information regarding the use of EDURANT in patients > 65 years of age. No dose adjustment of EDURANT is required in older patients (see section 5.2). EDURANT should be used with caution in this population.

Renal impairment
EDURANT has mainly been studied in patients with normal renal function. No dose adjustment of rilpivirine is required in patients with mild or moderate renal impairment. In patients with severe renal impairment or end-stage renal disease, rilpivirine should be used with caution.
In patients with severe renal impairment or end-stage renal disease, the combination of rilpivirine with a strong CYP3A inhibitor (e.g., ritonavir-boosted HIV protease inhibitor) should only be used if the benefit outweighs the risk (see section 5.2).

Treatment with rilpivirine resulted in an early small increase of mean serum creatinine levels which remained stable over time and is not considered clinically relevant (see section 4.8).

Hepatic impairment
There is limited information regarding the use of EDURANT in patients with mild or moderate hepatic impairment (Child-Pugh score A or B). No dose adjustment of EDURANT is required in patients with mild or moderate hepatic impairment. EDURANT should be used with caution in patients with moderate hepatic impairment. EDURANT has not been studied in patients with severe hepatic impairment (Child-Pugh score C). Therefore, EDURANT is not recommended in patients with severe hepatic impairment (see section 5.2).

Pediatric population
EDURANT is not indicated for children and adolescents under 18 years old.

Pregnancy
Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely. Alternatively, switching to another ART regimen could be considered (see sections 4.4, 4.6, 5.1 and 5.2).

Method of administration
EDURANT must be taken orally, once daily with a meal (see section 5.2). It is recommended that the film-coated tablet be swallowed whole with water and not be chewed or crushed.
