Dr. Arjun Srivastav What Is Xovoltib 50 mg?
Xovoltib 50mg Tablet is used in the treatment of non-small cell lung cancer. It contains FDA-approved afatinib, which belongs to a group of anticancer medicines known as tyrosine kinase inhibitors (TKIs).
This medication is used in selected people with advanced or metastatic NSCLC, particularly when the tumour carries certain changes in the epidermal growth factor receptor (EGFR) gene. Testing the tumour can help the treating specialist determine whether an EGFR-targeted medicine is suitable.
The 50 mg mentioned in the product name refers to the tablet strength. It should not be taken to mean that every person receiving afatinib needs 50 mg each day. The prescribed dose can differ according to the treatment plan and may be changed if side effects occur.
Xovoltib 50 mg Uses
Xovoltib is prescribed for particular types of NSCLC rather than for lung cancer in general. Its use depends on the characteristics of the tumour and the indication for which it has been prescribed.
Your oncologist may consider it when:
- The cancer is non-small cell lung cancer.
- The disease is advanced or metastatic.
- Testing identifies an EGFR alteration for which afatinib is an appropriate treatment.
- The overall treatment history supports its use.
This medication has also been used in certain patients with squamous NSCLC following platinum-based chemotherapy, depending on the applicable treatment indication.
The decision is made from the pathology and molecular test results together with the patient’s previous and current cancer treatment.
How Does Xovoltib 50 mg Work?
Some lung cancer cells rely on receptor signals to receive instructions to grow and survive. The active ingredient interferes with several members of the ErbB receptor family, including EGFR.
By blocking these signalling pathways, it can slow the activity of cancer cells that depend on them. This is why identifying the molecular features of the tumour matters before choosing a targeted treatment.
The drug is different from conventional chemotherapy. It is designed to act on specific signalling proteins rather than working mainly by affecting rapidly dividing cells throughout the body.
Xovoltib 50 mg Dosage
The dose of this medicine is decided by the treating oncologist. Do not choose the dose based only on the strength printed on the tablet pack.
Depending on the indication and the patient’s tolerance, the prescribed dose may be adjusted during treatment. Dose reductions are commonly used when adverse reactions become difficult to manage.
Your doctor may therefore prescribe a strength lower than 50 mg or make another adjustment rather than asking you to continue the same dose despite troublesome reactions.
Take only the amount prescribed for you and do not alter the schedule without medical advice.
What If You Miss a Dose?
Do not take two tablets to make up for a missed dose. The appropriate action depends on how close you are to the next scheduled dose. If the next dose is due soon, the missed tablet may need to be skipped rather than taken late.
Different product information sources use specific time limits for deciding whether a missed dose should be taken. If you are unsure what to do, contact your pharmacist or oncology team rather than guessing.
What If You Take Too Much Xovoltib?
Taking more than prescribed can increase the likelihood or severity of adverse effects. If you accidentally take an extra dose, contact your doctor, pharmacist or an appropriate medical service for advice. Tell them the strength, number of tablets taken and approximate time of the dose.
Do not take another tablet later to compensate for the mistake unless a healthcare professional tells you to do so.
How to Take Xovoltib 50 mg
Take Xovoltib 50 mg exactly as directed by your oncologist. Keep these points in mind:
- Take this medication once daily, at about the same time each day.
- Swallow the tablet whole with a glass of water.
- Do not crush, chew or break the tablet unless your healthcare professional has given you specific instructions.
- Take it on an empty stomach, following the recommended gap between the tablet and meals.
- If you have difficulty swallowing the tablet, speak with your oncology team before changing the way you take it.
- Continue taking it for as long as your doctor recommends, even if you are feeling well.
The timing of food matters because eating can affect how it is absorbed.
Can Xovoltib 50 mg Be Taken With Food?
No. This medication should not be taken with a meal because food can affect its absorption.
Australian guidance advises taking it one hour before food or three hours after food. Follow the instructions supplied with your prescribed product and those given by your treating team.
Keeping the timing consistent can make the daily routine easier to manage.
Xovoltib 50 mg Side Effects
Side effects can vary between patients. Some are relatively common and can usually be managed with advice from the oncology team, while others require immediate assessment.

Xovoltib 50 mg Safety Precautions
Before treatment begins, tell your oncologist about your existing medical conditions and every medicine or supplement you take. Extra care may be needed if you have:
- Lung disease or previous lung problems
- Liver disease
- Kidney impairment
- A history of significant gastrointestinal problems
- Heart disease
- Existing eye problems
- A previous allergic reaction to the active ingredient
Diarrhoea deserves particular attention during treatment because substantial fluid loss can lead to dehydration. Your treatment team may give you instructions on managing it and when to contact them. Skin care may also become part of your routine, particularly if you develop dryness, rash or sensitivity.
Xovoltib 50 mg in Pregnancy and Breastfeeding
This medication can harm an unborn baby. If you are pregnant, planning a pregnancy or could become pregnant, discuss this with your doctor before treatment starts.
Women who can become pregnant should discuss suitable contraception with their healthcare professional. The prescribing information also recommends avoiding pregnancy for a specified period after the final dose.
Breastfeeding should not be continued during afatinib treatment and for the recommended period following the last dose. If pregnancy occurs while taking Xovoltib, contact your treating specialist as soon as possible.
Xovoltib 50 mg Drug Interactions
It can interact with medicines that affect how it is transported in the body. One group that deserves particular attention is P-glycoprotein (P-gp) inhibitors and inducers.
P-gp inhibitors may increase exposure to afatinib, while P-gp inducers can reduce exposure. Your doctor may therefore consider the medicines you are already taking before deciding on the appropriate regimen.bTell your healthcare professional about:
| Product or medicine | What to discuss |
| Prescription medicines | Some can alter afatinib exposure |
| P-gp inhibitors | May increase afatinib exposure |
| P-gp inducers | May reduce afatinib exposure |
| Non-prescription medicines | Should be checked before use |
| Vitamins and supplements | May not be suitable with cancer treatment |
| Herbal products | Their effects and interactions can be difficult to predict |
Never stop an existing prescription on your own because you have started Xovoltib.
Monitoring During Xovoltib Treatment
Regular follow-up is part of afatinib treatment. Your oncology team needs to assess both the cancer and your response to the medicine.
Depending on your circumstances, appointments may include:
- Reviewing symptoms and side effects
- Checking how well the cancer is responding
- Monitoring diarrhoea and skin reactions
- Assessing breathing-related symptoms
- Reviewing liver function
- Discussing eye or heart symptoms when relevant
- Deciding whether the current dose remains appropriate
If adverse effects become difficult to manage, your doctor may temporarily interrupt treatment or reduce the dose.

- Do not use tablets that are damaged, discoloured or otherwise appear unusual.
- Ask your pharmacist about the appropriate disposal of unused or expired tablets.
Xovoltib 50 mg is prescribed for selected cases of non-small cell lung cancer. The appropriate strength and treatment schedule depend on the individual patient’s cancer characteristics, response and tolerance, so the medicine should be used only as directed by the treating specialist.
The price, pack size and availability of Xovoltib 50 mg can vary depending on the supplier and current stock. Afatinib products have been registered in Australia, but the supply status of individual brands and strengths can change. The TGA has recorded the discontinuation of GIOTRIF 50 mg from the Australian market in January 2025, so the current availability of Xovoltib 50 mg should be confirmed before ordering.
For current product details, pricing and supply information, you can check AustraliaRXMeds before placing an order.
