Product Description

Hertab 250 mg contains lapatinib, an oral targeted anticancer medicine used in adults with HER2-positive breast cancer when your oncology team determines it is appropriate. This product is supplied as 250 mg tablets in a 1 pack / 30 tabs presentation, designed to support planned therapy and structured monitoring. Lapatinib is not a general-purpose medicine and should only be used within a confirmed diagnosis and a specialist-led treatment plan.

In HER2-positive breast cancer, treatment decisions are individualized and may depend on whether the disease is advanced or metastatic, what therapies have been used before, and how the cancer is behaving on scans and laboratory assessments. Lapatinib is often used in combination regimens rather than as a stand-alone treatment, and your oncologist will explain the role of the medicine, the expected goals, and the monitoring schedule. Do not start, stop, or change the way you take Hertab 250 mg without medical supervision, and do not rely on general online information to replace a personalised oncology plan.

Generic Meds Mart supplies Hertab 250 mg lapatinib tablets in original manufacturer packaging sourced through licensed channels. The outer carton and blisters typically show the brand name, strength, active ingredient, batch number, and expiry date so your clinic or pharmacy can verify the product on receipt. Orders are packed in discreet outer parcels to support privacy, and delivery options are designed for international customers. If you are comparing options, confirm the correct strength and pack size with your care team before ordering and avoid making decisions based only on lapatinib price.

Key Uses

Hertab 250 mg lapatinib is used in HER2-positive breast cancer when inhibition of HER2-driven signalling is clinically appropriate and the patient’s overall treatment plan supports an oral targeted option. In advanced or metastatic settings, lapatinib may be used as part of a combination regimen selected by an oncologist, especially when a structured oral schedule is helpful for ongoing treatment coordination and monitoring.

Your oncology team will define whether lapatinib is being used alongside another anticancer medicine, how response will be assessed, and what symptoms or lab changes should trigger contact with the clinic. Because targeted therapy still carries meaningful risks, lapatinib treatment is typically paired with monitoring for side effects, interactions, and adherence to the planned schedule. Always follow your specialist’s instructions, and if you need to order lapatinib online, do so only after your regimen and follow-up plan are clearly confirmed.

How Lapatinib Works in Chemotherapy

Lapatinib works by inhibiting specific tyrosine kinases linked to tumour growth signals, particularly HER2 (ErbB2) and, in many cases, EGFR (ErbB1). In HER2-positive breast cancer, overactive HER2 signalling can drive uncontrolled cell growth and survival pathways. By blocking the intracellular kinase activity, lapatinib reduces downstream signalling that cancer cells use to proliferate and resist cell death, which can contribute to disease control when taken consistently within the prescribed regimen.

Because this mechanism is targeted signal inhibition rather than traditional DNA-damaging chemotherapy, lapatinib has a side-effect profile that differs from many classic cytotoxic agents. However, monitoring remains essential, and treatment may require supportive care, dose adjustments, or temporary interruption depending on tolerability. Your oncologist balances expected benefit with safety considerations such as gastrointestinal effects, liver function changes, and potential cardiac effects in susceptible patients.

Dosage & Administration

Hertab 250 mg tablets are taken by mouth exactly as prescribed by your oncologist. Lapatinib is commonly taken once daily as a total dose made up of multiple 250 mg tablets, and it may be scheduled in combination with other anticancer medicines depending on the protocol. Swallow tablets whole with water and do not crush or split them unless your clinic provides a specific instruction. Try to take the medicine at the same time each day to support consistent exposure and reliable monitoring.

Drug interactions can be clinically important with lapatinib. Some medicines can increase or decrease lapatinib levels in the body, including certain antibiotics, antifungals, anticonvulsants, and herbal products such as St John’s wort. Always share a complete list of prescription medicines, over-the-counter products, and supplements with your oncology team and pharmacist. Never self-adjust dosing, and if a dose is missed, follow your clinic’s guidance rather than taking extra tablets to “catch up.”

Precautions

Lapatinib can cause diarrhoea and dehydration, which may become serious if not managed early. Your oncology team may provide a plan for anti-diarrhoeal treatment, hydration, and when to contact the clinic. Liver function changes can occur, so scheduled blood tests are important even if you feel well. Report symptoms such as yellowing of the skin or eyes, dark urine, severe fatigue, or persistent abdominal pain promptly.

Cardiac effects such as reduced left ventricular ejection fraction can occur in some patients, particularly those with existing heart disease or other risk factors, so your oncologist may arrange baseline and follow-up heart monitoring when appropriate. Lung toxicity is uncommon but can be serious, so new or worsening shortness of breath, cough, or fever should be assessed urgently. Lapatinib may harm an unborn baby, so effective contraception is required during treatment, and pregnancy planning must be discussed with your specialist.

Lapatinib Side Effects

Common side effects

Common lapatinib side effects may include diarrhoea, nausea, vomiting, reduced appetite, abdominal discomfort, fatigue, headache, mouth soreness, and skin changes such as rash or dryness. Some patients notice soreness of hands or feet when lapatinib is combined with other agents, and blood tests may show liver enzyme changes that require monitoring. Many side effects can be managed with supportive care when reported early, but you should not change the dose on your own.

Serious side effects

Serious side effects require urgent medical attention and may include severe or persistent diarrhoea with dehydration, significant liver injury, new or worsening shortness of breath, chest pain, fainting, or signs of a clinically important heart problem. Severe skin reactions are rare but can occur, especially if accompanied by fever, blistering, or widespread pain. If you experience alarming symptoms, seek urgent medical care and tell clinicians you are taking lapatinib.

Storage

Store Hertab 250 mg tablets below 25–30 °C, protected from moisture and direct light, and keep them in the original blister packaging until use to reduce mix-ups and maintain stability. Keep all medicines out of reach of children and pets. Do not use tablets after the expiry date printed on the carton or blisters, and follow pharmacist guidance for safe disposal of unused or expired tablets.
