How to use Lenvima

Read the Patient Information Leaflet if available from your pharmacist before you start taking lenvatinib and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once daily. Swallow the capsules whole. If you have trouble swallowing the capsules whole, place the capsules in a glass with a small amount of water or apple juice (1 tablespoon/15 milliliters). Let the capsules sit in the liquid for 10 minutes. Do not crush or break the capsules. After 10 minutes, stir the contents of the glass for at least 3 minutes. Drink all of the mixture right away. Then rinse the glass with another small amount of water or apple juice and drink the rinsing liquid to make sure you have taken the entire dose. Do not prepare a supply in advance.

The dosage is based on your medical condition, response to treatment, and laboratory tests.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Do not increase your dose or use this drug more often or for longer than prescribed. Your condition will not improve any faster, and your risk of serious side effects will increase.

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.

Dry mouth, hoarseness, nose bleeds, tiredness, weight loss, headache, muscle/joint pain, trouble sleeping, change in taste, diarrhea, constipation, upset stomach, nausea, vomiting, or loss of appetite may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Vomiting or diarrhea that doesn't stop may result in a serious loss of body water (dehydration). Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual dry mouth/thirst, dizziness, or lightheadedness.

To relieve dry mouth, suck (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.

Pain or sores in the mouth and throat may occur. Brush your teeth carefully/gently, avoid using mouthwash that contains alcohol, and rinse your mouth frequently with cool water mixed with baking soda or salt. It may also be best to eat soft, moist foods.

Temporary hair loss may occur. Normal hair growth should return after treatment has ended.
