Product Description

Herduo 250 mg contains lapatinib, an oral targeted medicine used in adults with HER2-positive breast cancer when your oncology specialist determines it is suitable. Lapatinib is typically used for advanced or metastatic breast cancer in defined regimens, including combinations where a HER2-targeted approach is needed and treatment goals require long-term disease control. Herduo is supplied as 250 mg tablets in a 1 pack / 30 tabs presentation, supporting planned dosing and ongoing monitoring.

Unlike infusion-based biologic therapies, lapatinib is taken by mouth, but it still requires careful specialist oversight. Your oncologist considers tumour biology (including HER2 status), prior treatments, liver function, heart risk, drug interactions, and tolerability before choosing a lapatinib-containing plan. Herduo 250 mg is not a medicine to start, stop, or modify without medical guidance, and it should not be used as a substitute for specialist care.

Generic Meds Mart supplies Herduo 250 mg lapatinib tablets in original manufacturer packaging sourced through licensed channels. The carton and blisters typically show the brand name, strength, active ingredient, batch number, and expiry date so your pharmacy or clinic can verify the product on receipt. Orders are shipped in discreet outer packaging, pricing is displayed in USD, and delivery options support patients coordinating refills with oncology follow-up.

Key Uses

Herduo 250 mg lapatinib is used as part of specialist-led treatment plans for HER2-positive breast cancer, most often in advanced settings where targeted therapy is needed. Lapatinib may be used after progression on prior HER2-directed treatments, or as recommended by local guidelines for specific patient profiles.

Depending on the protocol, lapatinib may be combined with other anticancer medicines such as capecitabine, or used with endocrine therapy in hormone receptor-positive, HER2-positive disease when a dual approach is appropriate. The exact regimen, line of therapy, and monitoring schedule are defined by your oncologist, and therapy should be reviewed regularly to balance benefit and tolerability.

How Lapatinib Works in Chemotherapy

Lapatinib is a small-molecule tyrosine kinase inhibitor that targets the intracellular domains of HER2 (ErbB2) and EGFR (ErbB1). In HER2-positive breast cancer, HER2-driven signalling can promote tumour cell growth and survival. By inhibiting these kinases, lapatinib reduces downstream signalling through pathways involved in proliferation and resistance, which can contribute to disease control when the medicine is taken consistently as prescribed.

Because lapatinib acts on signalling rather than directly damaging DNA, its effect depends on sustained exposure and adherence to the dosing plan. This targeted mechanism also explains why the side effect profile differs from classic cytotoxic chemotherapy, although serious risks can still occur and require monitoring. Your oncology team may monitor liver tests, heart function where relevant, and symptoms suggesting toxicity or interactions.

Dosage & Administration

Herduo 250 mg tablets are taken by mouth exactly as prescribed by your oncologist. Total daily doses in lapatinib regimens are commonly in the range of 1250–1500 mg per day, which means multiple 250 mg tablets taken once daily, but the exact number of tablets, timing, and duration depend on the combination regimen and your individual factors.

Swallow tablets whole with water and take them at the same time each day. Follow your clinician’s advice on whether to take lapatinib with food or on an empty stomach, as administration instructions can affect absorption. Do not take extra tablets to make up for a missed dose unless your oncology team explicitly instructs you to do so.

Precautions

Lapatinib can affect the liver, and your oncologist may order baseline and periodic liver function tests during treatment. Contact your clinic urgently if you develop symptoms such as yellowing of the skin or eyes, dark urine, severe abdominal pain, or unusual fatigue. Lapatinib can also affect heart function in some patients, so new shortness of breath, swelling, chest discomfort, or palpitations should be assessed promptly.

Drug interactions matter. Some medicines can increase or decrease lapatinib levels, including certain antibiotics, antifungals, anticonvulsants, and herbal products such as St John’s wort. Always share a complete list of prescriptions, over-the-counter products, and supplements with your oncology pharmacist. Pregnancy should be avoided during therapy, and contraception planning should be discussed with your specialist.

Lapatinib Side Effects

Common side effects

Common lapatinib side effects may include diarrhoea, nausea, vomiting, loss of appetite, fatigue, rash or acne-like skin changes, mouth soreness, and hand–foot skin reactions when used with other medicines. Mild changes in liver tests can occur on monitoring. Tell your clinic early about diarrhoea or worsening skin reactions so supportive care can be started promptly and treatment interruptions can be avoided where possible.

Serious side effects

Serious side effects require urgent medical attention and may include severe or persistent diarrhoea with dehydration, significant liver injury, severe skin reactions with blistering or peeling, new or worsening shortness of breath, heart rhythm disturbances, or symptoms of reduced heart function. Signs of infection, high fever, confusion, fainting, or rapidly worsening symptoms should be treated as urgent. If you experience severe adverse effects, do not self-adjust the dose; contact your oncology team immediately for instructions.

Storage

Store Herduo 250 mg in the original packaging below 25–30 °C, protected from moisture and direct light. Keep medicines out of reach of children and do not use tablets after the expiry date printed on the pack. If you are travelling or coordinating shipments, keep tablets in the labelled blister or bottle to avoid mix-ups and to support verification by your clinic.
