Retevmo ^*

Retevmo should be taken as prescribed, but if you miss a dose, your action depends on the timing. If it is more than 6 hours until your next scheduled dose, take the missed dose as soon as possible. If it is less than 6 hours until your next dose, you should skip the missed dose completely. Do not take two doses at once to make up for a missed one.

Retevmo can be taken either with or without food, providing flexibility for your daily schedule. Taking it with a meal does not significantly change how the medication is absorbed by your body. It is most important to take your doses at roughly the same times each day to maintain a consistent level of the drug in your system. Swallow the capsules whole with water.

Retevmo capsules should be stored at room temperature, between 68°F to 77°F (20°C to 25°C). Keep the medication in its original container with the lid tightly closed to protect it from moisture and light. Do not store it in a bathroom or other humid environment. Be sure to keep this and all other medicines out of the reach of children and pets for their safety.

There is no specific contraindication against moderate alcohol use with Retevmo, but it is wise to be cautious. Both alcohol and Retevmo can affect the liver. Combining them could potentially increase the risk of liver-related side effects. You should discuss your alcohol consumption with your doctor. They can provide personalized advice based on your overall health and liver function.

Retevmo begins to work as soon as it enters your system, but the time it takes to see a response varies. Some patients may notice an improvement in symptoms or a reduction in tumor size within the first couple of months. For others, it might take longer. Your oncologist will monitor your progress with regular scans and tests to determine how effective the treatment is for you.

Yes, Retevmo can cause high blood pressure (hypertension), which is one of its common side effects. Your doctor will monitor your blood pressure regularly before you start and during your treatment. If your blood pressure becomes too high, your doctor may prescribe medication to control it or adjust your Retevmo dose. It is important to report any symptoms like headaches or dizziness.

If you vomit after taking a dose of Retevmo, you should not take another dose to replace it. Simply wait and take your next dose at its regularly scheduled time. Taking an extra dose could increase the risk of experiencing side effects. If vomiting becomes a persistent problem, you should contact your healthcare provider for advice as they may be able to help manage the nausea.

Retevmo can interact with several other drugs, which may affect how it works or increase your risk of side effects. It is very important to tell your doctor about all medicines you take. This includes prescriptions, over-the-counter drugs, and herbal supplements. Specifically, drugs known as strong CYP3A inhibitors or inducers can have significant interactions. During treatment with Retevmo, you should avoid taking over-the-counter substances containing St. John’s wort and antacids that contain aluminum, magnesium, or calcium. Consult a doctor for more information on how to take Retevmo with these medicines.

Yes, Retevmo can cause fatigue or a feeling of weakness in many patients. This is one of the most common side effects associated with the treatment. It is important to listen to your body and get enough rest. Pacing your activities throughout the day can also help manage tiredness. If the fatigue becomes severe and interferes with your daily life, discuss it with your healthcare team.

Retevmo is not considered a traditional chemotherapy. It is a type of targeted therapy. Unlike traditional chemotherapy, which can affect all rapidly dividing cells, Retevmo specifically targets and inhibits the altered RET proteins that drive tumor growth. This targeted approach often results in a different and sometimes more manageable side effect profile compared to conventional chemo.

Retevmo can cause harm to an unborn baby, so you should not become pregnant while taking it. Women who are able to become pregnant should use effective birth control during treatment and for at least one week after the final dose. Men with female partners who can become pregnant should also use effective contraception during treatment and for one week after the last dose.

Retevmo is different because it is a precision medicine that targets a specific genetic driver of cancer. Its active ingredient, selpercatinib, works by blocking RET kinase enzymes, which are abnormal in certain lung and thyroid tumors. This is unlike radiation or traditional chemotherapy. This targeted action makes Retevmo a valuable option only for patients with confirmed RET gene alterations.

Retevmo is not typically associated with the complete hair loss often seen with traditional chemotherapy. While a skin rash can occur, and some minor hair thinning is possible, widespread hair loss is not a commonly reported side effect. As a targeted therapy, it has a different mechanism of action. If you experience any unusual hair changes, you should still mention them to your doctor.

While taking Retevmo, your doctor will require regular lab tests to monitor your health. These tests typically include liver function tests to check for liver toxicity and a complete blood count. Your doctor will also regularly check your electrolytes and may perform an electrocardiogram (ECG) to monitor your heart's electrical activity. This routine monitoring helps ensure the treatment is safe for you.

Retevmo is approved for use in some pediatric patients. It can be prescribed for children aged 12 years and older who have specific types of advanced thyroid cancer (RET-mutant medullary thyroid cancer or RET fusion-positive thyroid cancer). It is not currently approved for children with non-small cell lung cancer. The dosage for children is based on body weight.
