4.2       Posology and method of administration

Eviplera should be initiated by a physician experienced in the management of HIV infection.
Posology

Adults
The recommended dose of Eviplera is one tablet, taken orally, once daily. Eviplera must be taken with food (see section 5.2).

Where discontinuation of therapy with one of the components of Eviplera is indicated or where dose modification is necessary, separate preparations of emtricitabine, rilpivirine hydrochloride and tenofovir disoproxil are available. Please refer to the Summary of Product Characteristics for these medicinal products.

If a patient misses a dose of Eviplera within 12 hours of the time it is usually taken, the patient should take Eviplera with food as soon as possible and resume the normal dosing schedule. If a patient misses a dose of Eviplera by more than 12 hours, the patient should not take the missed dose and simply resume the usual dosing schedule.

If a patient vomits within 4 hours of taking Eviplera another Eviplera tablet should be taken with food.
If a patient vomits more than 4 hours after taking Eviplera they do not need to take another dose of Eviplera until the next regularly scheduled dose.

Dose adjustment
If Eviplera is co-administered with rifabutin, an additional 25 mg tablet of rilpivirine per day is recommended to be taken concomitantly with Eviplera, for the duration of the rifabutin co- administration (see section 4.5).

Special populations

Elderly
Eviplera has not been studied in patients over the age of 65 years. Eviplera should be administered with caution to elderly patients (see sections 4.4 and 5.2).

Renal impairment
Treatment with Eviplera 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).

Limited data from clinical studies support once daily dosing of Eviplera in patients with mild renal impairment (creatinine clearance (CrCl) 50-80 mL/min). However, long-term safety data for the emtricitabine and tenofovir disoproxil components of Eviplera have not been evaluated in patients with mild renal impairment. Therefore, in patients with mild renal impairment Eviplera should only be used if the potential benefits of treatment outweigh the potential risks (see sections 4.4 and 5.2).

Eviplera is not recommended for patients with moderate or severe renal impairment (CrCl < 50 mL/min). Patients with moderate or severe renal impairment require a dose interval adjustment of emtricitabine and tenofovir disoproxil that cannot be achieved with the combination tablet (see sections 4.4 and 5.2).

Hepatic impairment
There is limited information regarding the use of Eviplera in patients with mild or moderate hepatic impairment (Child-Pugh-Turcotte (CPT) Score A or B). No dose adjustment of Eviplera is required in patients with mild or moderate hepatic impairment. Eviplera should be used with caution in patients with moderate hepatic impairment. Eviplera has not been studied in patients with severe hepatic impairment (CPT Score C). Therefore, Eviplera is not recommended in patients with severe hepatic impairment (see sections 4.4 and 5.2).

If Eviplera is discontinued in patients co-infected with HIV and hepatitis B virus (HBV), these patients should be closely monitored for evidence of exacerbation of hepatitis (see section 4.4).

Paediatric population
The safety and efficacy of Eviplera in children under the age of 18 years have not been established.
Currently available data are described in section 5.2, but no recommendation on a posology can be made.

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

Method of administration

Eviplera must be taken orally, once daily with food (see section 5.2). It is recommended that Eviplera be swallowed whole with water. The film-coated tablet should not be chewed, crushed or split as it may impact the absorption of Eviplera.
