Lenvima (Lenvatinib) Dosage: A Comprehensive Guide for Indian Patients

Understanding Lenvima (Lenvatinib) Dosage for Cancer Treatment in India

Lenvima, with the active ingredient lenvatinib, is a vital prescription medication used in the treatment of various types of cancer. As a kinase inhibitor, it plays a crucial role in managing advanced stages of certain cancers. This guide aims to provide clear, practical information about Lenvima dosages, strengths, and how to take it, specifically tailored for patients in India. It's essential to remember that this information is for educational purposes and should not replace the advice of your healthcare provider.

What is Lenvima and How Does it Work?

Lenvima belongs to a class of drugs known as kinase inhibitors. Kinases are proteins that help cells grow and divide. In certain cancers, these kinases can become overactive, leading to uncontrolled cell growth. Lenvima works by blocking the action of these specific kinases, thereby slowing down or stopping the growth of cancer cells. It is typically administered as an oral capsule.

Lenvima Strengths and Forms

Lenvima is available in oral capsule form and comes in two primary strengths:

• 4 milligrams (mg)
• 10 milligrams (mg)

The specific strength prescribed will depend on the type and stage of cancer, as well as individual patient factors.

Dosage for Different Types of Cancer

The dosage of Lenvima is highly individualized and depends on several factors, including the specific type of cancer being treated, the patient's body weight, and how well the patient tolerates the medication. Your doctor will determine the most appropriate dosage for you. Below are common dosage guidelines for different conditions:

1. Advanced Renal Cell Carcinoma (RCC)

When used to treat advanced RCC, Lenvima is often prescribed in combination with other cancer medications like pembrolizumab (Keytruda) or everolimus (Afinitor, Zortress). The dosage regimen can vary:

• Lenvima in combination with pembrolizumab: Typically, Lenvima is taken as a 20 mg capsule once daily. Pembrolizumab is administered as an intravenous (IV) infusion every 3 weeks.
• Lenvima in combination with everolimus: Both Lenvima (18 mg oral capsule) and everolimus (5 mg oral tablet) are usually taken once per day.

It is crucial to adhere strictly to the prescribed schedule for both medications.

2. Advanced Endometrial Cancer

For adults with advanced endometrial cancer that has progressed after previous treatments and is not suitable for surgery or radiation, Lenvima is commonly prescribed alongside pembrolizumab (Keytruda). The typical dosage involves:

• Lenvima 20 mg taken once daily.
• Pembrolizumab 200 mg given as an IV infusion every 3 weeks.

Your doctor will provide precise instructions on how to take these medications.

3. Differentiated Thyroid Cancer (DTC)

For differentiated thyroid cancer (DTC) that has spread or recurred after treatment, the dosage of Lenvima is typically:

• 24 mg taken once per day.

This dosage may be adjusted by your doctor based on your response and tolerance.

4. Hepatocellular Carcinoma (HCC)

In adults with hepatocellular carcinoma (HCC) that cannot be treated with surgery, Lenvima is used as a first-line treatment. The dosage for HCC is based on the patient's body weight:

• If you weigh 60 kg (approximately 132 lb) or more: 12 mg taken once daily.
• If you weigh less than 60 kg: 8 mg taken once daily.

Your doctor will calculate the correct dosage based on your weight.

How to Take Lenvima Capsules

Lenvima capsules should be taken orally, usually once a day. It is important to swallow the capsules whole with water. Do not crush, chew, or break the capsules.

Special Instructions for Taking Lenvima Capsules:

In some cases, if swallowing the capsule whole is difficult, the contents can be dissolved in water or apple juice. Follow these steps carefully:

1. Add 3 milliliters (mL) of water or apple juice to a small cup.
2. Add the Lenvima capsules to the liquid.
3. Let the capsules dissolve completely for at least 10 minutes.
4. Stir the mixture for at least 3 minutes to ensure all capsules have fully dissolved.
5. Consume the mixture immediately.

If you are unable to consume the mixture immediately after preparation, it should be discarded. Always follow your doctor's specific instructions regarding the administration of Lenvima.

Dosage Adjustments and Side Effects

Your doctor may need to adjust your Lenvima dosage based on your response to the treatment, any side effects you experience, or other health conditions you may have, such as severe liver or kidney disease. It is crucial to report any new or worsening symptoms to your doctor promptly.

Common side effects can include high blood pressure, fatigue, diarrhea, decreased appetite, weight loss, and others. Your healthcare team will monitor you closely for side effects and manage them as needed.

When to Consult Your Doctor

It is essential to consult your doctor or healthcare provider for any questions regarding your Lenvima dosage or treatment plan. Always take the medication exactly as prescribed. Do not change your dosage or stop taking Lenvima without consulting your doctor first. Seek immediate medical attention if you experience severe side effects or have concerns about your treatment.
