VPXL (Voxilaprevir + Velpatasvir) – Patient Information

VPXL is an oral antiviral medicine used in the treatment of chronic Hepatitis C virus (HCV) infection. It combines two active ingredients—voxilaprevir and velpatasvir—in a single daily regimen. This combination is designed to target multiple steps in the HCV life cycle, helping achieve sustained viral response (a cure in most cases).

This information is intended to help you understand how VPXL works, how it is typically taken, and what to consider for safety and interactions. Always follow the directions provided by your healthcare professional and read the consumer medicine information (CMI) supplied with your product.

Indications (what VPXL is used for)

VPXL is used to treat chronic hepatitis C virus (HCV) infection in adults. It is suitable for many HCV genotypes and is commonly considered for people who have:

• Not previously received HCV treatment, or
• Previously received certain HCV medicines and require a retreatment option, depending on their clinical situation.

Your healthcare professional will determine the appropriate regimen based on:

• HCV genotype (if known)
• Previous treatment history
• Liver status (e.g., compensated cirrhosis)
• Drug interaction risks
• Kidney function (including whether dialysis is involved)

How VPXL works (mechanism of action)

Hepatitis C replicates using specific viral proteins and enzymes. VPXL contains two medicines that work at different points in this process:

• Velpatasvir: blocks the NS5A protein, a key factor for HCV replication and assembly.
• Voxilaprevir: inhibits the NS3/4A protease, preventing the virus from processing proteins correctly for replication.

Combined effect: Using both NS5A inhibition and NS3/4A protease inhibition together improves the chance of viral suppression and a durable cure across many HCV genotypes.

Pharmacokinetics (how the body handles the medicine)

Pharmacokinetics (PK) describes how the medicine is absorbed, distributed, metabolised, and eliminated. While individual results vary, the following points are generally relevant:

• Absorption: VPXL components are absorbed after oral dosing.
• Time to effect: Viral load typically decreases quickly after starting therapy, though monitoring is still required.
• Distribution: The medicines distribute into tissues, including areas involved in HCV replication.
• Metabolism: Both components are processed mainly by the liver (via drug-metabolising enzymes).
• Elimination: Metabolites are eliminated through the body, largely via hepatic and biliary pathways.

Clinical implication: Because these medicines are metabolised by the liver, liver impairment and interacting medicines can influence blood levels. This is why careful medication review is essential.

Typical use and treatment timing

VPXL is taken as a course of therapy. Many people take it for 12 weeks, but your exact duration may differ depending on your circumstances and previous treatment.

When should you take VPXL?

• Once daily at the same time each day (to help maintain consistent blood levels).
• You can take it with food or without food in many cases; however, food can influence absorption for certain medicines, so follow the guidance provided for your regimen.
• If you miss a dose, follow your healthcare professional’s instructions or the directions in the CMI.

Monitoring: Your clinician may arrange blood tests during treatment and after completion to confirm that the virus is no longer detectable (commonly referred to as sustained virologic response, SVR).

Food interactions

Food may affect the absorption of some antiviral medicines. With VPXL, the key practical points are:

• General advice: Follow the instructions provided with your medicine and regimen. If your CMI states that it can be taken with or without food, you can usually choose whichever fits your routine.
• Avoid extremes: If you experience stomach upset, consider taking it with a meal (unless your clinician advised otherwise).
• Reduce risk with antacids and acid-reducing agents: Medicines that significantly change stomach acidity can reduce absorption of some components.

Important: Acid-reducing medicines—especially proton pump inhibitors (PPIs) and some H2 blockers—often require careful timing or may be unsuitable depending on dose and regimen. Always discuss these with your healthcare professional.

Alcohol interactions

There is no single “universal” alcohol interaction that applies to all people in all situations. However, alcohol can worsen liver inflammation and damage, which is especially relevant for people with HCV and/or liver scarring.

• Recommended approach: Limit or avoid alcohol during HCV treatment and while your liver recovers.
• Safety: If you choose to drink alcohol, do so only after discussing with your clinician, and keep it minimal.

Why it matters: HCV can already affect the liver. Even small-to-moderate alcohol intake can increase the risk of progression in some individuals. Achieving viral cure is a major step, but liver health still needs protection.

Medicine interactions (drug–drug interactions)

VPXL can interact with other medicines because its components may be affected by liver enzymes and transport proteins. Some interactions can reduce effectiveness, while others can increase side effects.

Always provide a complete list of everything you take to your clinician or pharmacist, including:

• Prescription medicines
• Over-the-counter products
• Herbal supplements
• Vitamins or “natural” remedies

Common interaction categories to discuss

• Acid-reducing medicines (e.g., PPIs, H2 blockers, antacids)
• Seizure medicines (some can strongly affect antiviral levels)
• Rifampicin/rifabutin (used for certain infections)
• Anticoagulants (e.g., warfarin) and medicines affecting clotting
• Antiarrhythmics and other cardiac medicines
• St John’s wort and other herbal inducers
• HIV medicines (some combinations require careful adjustment)

What to do: Your pharmacist can check interactions and advise timing adjustments where appropriate. Do not start or stop medicines on your own.

Dosing (how to take VPXL)

Dose and duration must be personalised. Use only the regimen your healthcare professional prescribes for you.

Typical adult dosing

• Adults: commonly one dose once daily for 12 weeks, depending on prior treatment and liver status.

Swallowing: Take the tablet whole with water. If you have difficulty swallowing, speak with your healthcare professional—do not crush or modify unless specifically advised.

If you miss a dose

Missing doses can reduce treatment success. If you miss a dose, follow the instructions in the CMI or your healthcare professional’s plan. In general, many antiviral regimens provide guidance such as whether to take it as soon as you remember or skip if close to the next dose. Because timing guidance can vary, use the product directions specific to your VPXL pack.

Safety profile (who should take care)

Most people tolerate VPXL well. However, like all medicines, it can cause side effects. Some risks are more likely when interacting medicines are also used.

Common side effects

• Headache
• Nausea
• Tiredness or fatigue
• Diarrhoea
• Reduced appetite

Less common but important reactions

Contact urgent medical help if you experience signs of severe allergy or other serious issues, such as:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing
• Severe rash or blistering skin
• Uncontrolled vomiting or severe persistent abdominal pain

Liver status considerations

Because these medicines involve the liver in metabolism and because the liver is central to HCV-related disease, your clinician will assess:

• Whether you have cirrhosis and whether it is compensated
• Baseline liver blood tests
• Ongoing monitoring during therapy

Kidney function

Many patients with reduced kidney function can still be treated, but dosing decisions may require review. Always provide your most recent kidney test results to your clinician.

Practical use tips (getting the best results)

• Take at the same time daily to build a routine.
• Keep a medication schedule (calendar reminder or mobile alarm).
• Do not stop early even if you feel better—completion is important for cure rates.
• Avoid starting new supplements without checking interactions.
• Attend follow-up blood tests as advised to confirm response and monitor safety.
• Tell your healthcare team about all medications—including herbal products.

Alternative options for HCV treatment (discuss with your clinician)

Hepatitis C treatment options are tailored to genotype, prior therapy, and liver status. Depending on your situation, clinicians may consider other direct-acting antivirals such as:

• Glecaprevir/pibrentasvir
• Sofosbuvir-containing regimens
• Other pangenotypic combinations (depending on clinical scenario)

Why your doctor chooses a specific regimen: Not all treatments are appropriate for every previous treatment history or liver condition. VPXL may be preferred in certain cases, especially where retreatment is needed.

If you want to explore alternatives, ask your healthcare professional about:

• Expected cure rates for your specific HCV profile
• Duration of therapy
• Interaction risks with your current medicines
• Whether acid-reducing medicines can be used alongside your plan
