Contraindications
- Hypersensitivity to the active substances or to any of the excipients
- Severe hepatic impairment (Child-Pugh C)
- Concomitant use with atazanavir-containing products, atorvastatin, simvastatin, dabigatran etexilate or ethinyl oestradiol-containing products
- Concomitant use with strong P-gp and CYP3A inducers (e.g. rifampicin, carbamazepine, St John's wort (Hypericum perforatum), phenobarbital, phenytoin and primidone)
Side effects
- Headache (very common)
- Fatigue (very common)
- Diarrhoea and nausea (common)
- Asthenia (common)
- Elevation in total bilirubin (common)
- Angioedema (uncommon); pruritus (frequency not known)
Interactions
- Glecaprevir and pibrentasvir inhibit P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and organic anion transporting polypeptide (OATP) 1B1/1B3 - co-administration may increase plasma concentrations of substrates of these transporters (e.g. dabigatran etexilate)
- Strong P-gp/CYP3A inducers (rifampicin, carbamazepine, St John's wort, phenobarbital, phenytoin, primidone) - contraindicated
- Statins (atorvastatin, simvastatin) and atazanavir-containing products - contraindicated
- Ethinyl oestradiol-containing products - contraindicated
- Co-administration is not recommended with several further medicinal products as detailed in SPC section 4.5 (full section truncated in the fetched source)
Clinical monograph
How it works
Glecaprevir inhibits the HCV NS3/4A protease required for viral polyprotein processing, while pibrentasvir inhibits the NS5A protein essential for viral replication and assembly, giving complementary pangenotypic activity.
Prescribing in practice
- It is contraindicated in decompensated (Child-Pugh C) liver disease, and cases of hepatitis B reactivation mean patients should be screened for HBV before starting.
- It is a substrate and inhibitor of P-glycoprotein and BCRP and interacts with statins, certain anticonvulsants, rifampicin and ethinylestradiol-containing products, which must be reviewed.
- Tablets should be taken with food once daily to ensure adequate absorption.
Monitoring
Check hepatitis B status and baseline liver function before treatment, with on-treatment monitoring guided by the degree of underlying liver disease.
Counselling the patient
- Take the tablets with food at the same time each day to complete the short course.
- Tell your prescriber about all other medicines, including statins and any herbal products such as St John's wort.
- Mention any past hepatitis B infection so it can be monitored during treatment.
Evidence & guidelines
