Dr. Arjun Srivastav What Is Erlonat 100 mg?
Erlonat 100 mg is a targeted anticancer medicine containing 100 mg of erlotinib per tablet. Erlotinib belongs to a group of medicines called tyrosine kinase inhibitors, which act on signals involved in cancer-cell growth.
The medicine works by blocking the epidermal growth factor receptor (EGFR), a protein that helps regulate cell growth and division. In cancers that respond to this treatment, blocking EGFR signalling can slow the growth of cancer cells.
Erlonat is prescribed for selected patients with non-small cell lung cancer and may be used alongside gemcitabine for certain cases of pancreatic cancer. Its suitability depends on the diagnosis, tumour characteristics, and prescribed treatment plan.
What Is Erlonat 100 mg Used For?
Erlonat 100 mg is used in specific cancer-treatment settings rather than for every type of lung or pancreatic cancer.
- Non-small cell lung cancer (NSCLC): Erlotinib may be prescribed for eligible patients with locally advanced or metastatic NSCLC, depending on the clinical circumstances and applicable treatment guidance.
- Pancreatic cancer: It may be used with gemcitabine for certain patients with locally advanced, unresectable or metastatic pancreatic cancer.
The appropriate regimen depends on the patient’s diagnosis and medical assessment. A cancer specialist determines whether it is suitable and whether it should be used alone or with another medicine.
How Does Erlonat 100 mg Work?
Erlotinib targets EGFR, a receptor involved in pathways that tell certain cells to grow and divide. Some cancer cells rely on these signals to support their growth.
By inhibiting EGFR tyrosine kinase activity, erlotinib interferes with these pathways. This can slow cancer cell growth in patients whose disease is suitable for the treatment.
Unlike conventional chemotherapy, which affects rapidly dividing cells through different mechanisms, the medicine works by targeting a particular signalling pathway. It is still a cancer medicine and can cause serious adverse effects, so treatment requires medical supervision.
How to Take Erlonat 100 mg
Follow the instructions provided by your oncologist and the prescribing information for your medicine.
- Take the tablet by mouth at the prescribed time each day.
- It is generally taken on an empty stomach, at least one hour before food or two hours after eating.
- Swallow the tablet whole with water unless your healthcare professional provides different instructions.
- Tell your treating team about all prescription and non-prescription medicines, vitamins, supplements, or herbal products you use.
- Continue treatment for the duration advised by your oncologist. Do not change the dose or stop treatment on your own.
If swallowing the tablet is difficult or you cannot keep it down, contact your healthcare team for advice rather than changing how you take it.
Erlonat 100 mg Dosage
The appropriate medicine dose depends on the cancer being treated, the treatment regimen, other medicines, and how well the patient tolerates therapy.
For context, Australian product information for erlotinib lists different usual doses for different indications. A 150 mg daily dose is listed for NSCLC, while 100 mg daily is listed for pancreatic cancer when the drug is combined with gemcitabine. These are prescribing-information reference doses, not instructions to start or change treatment independently.
Missed Dose
If you miss a dose, follow the instructions provided by your oncology team or pharmacist. Do not take an extra tablet to make up for the missed dose without professional advice.
Overdose
Taking more erlonat 100 tablets than prescribed may increase the risk of serious adverse effects. Seek urgent medical advice if you have taken too much, even if you feel well.
Erlonat 100 mg Side Effects

Seek emergency assistance for severe breathing difficulty or other immediately life-threatening symptoms. Do not wait for a routine appointment if a serious reaction is suspected.
Drug Interactions
Other medicines can change erlotinib levels in the body or affect how well it works. Give your oncologist and pharmacist a complete list of your medicines before treatment begins and whenever something changes.
| Medicine or substance | Why it matters |
| Acid-reducing medicines, including proton pump inhibitors | Raising stomach pH can reduce erlotinib absorption. The combination should be reviewed by the treating team. |
| Certain antibiotics and antifungals | Some medicines affect CYP3A4 enzymes, which can change erlotinib exposure. |
| Certain seizure medicines | Enzyme-inducing medicines, such as carbamazepine or phenytoin, may lower erlotinib levels. |
| Warfarin and other relevant anticoagulants | Closer monitoring may be required because of potential interactions and bleeding risks. |
| Smoking | Cigarette smoking can reduce erlotinib exposure and affect treatment. Tell your oncologist if you smoke or stop smoking. |
This table gives examples, not a complete interaction list. Do not stop a prescribed medicine or alter its timing without advice from your healthcare professional. Acid-reducing treatments in particular need individual review because the appropriate management depends on the medicine involved.
Safety Advice
Heart Health
Inform your doctor about existing heart conditions and report new chest discomfort, fainting or unusual breathlessness.
