Tasigna ^*

Tasigna is a targeted therapy used to treat Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML). This specific type of blood and bone marrow cancer is characterized by the overproduction of abnormal white blood cells. Tasigna works by blocking the signals that cause these cancerous cells to grow and multiply. It is not used for other types of cancer.

Tasigna begins to work soon after you start treatment, but the effects are seen over time. A response to Tasigna is measured by blood tests that count the number of cells with the Philadelphia chromosome. Your doctor will perform regular blood tests to monitor how well the medication is working. It may take several weeks or months to see significant improvement in your blood counts.

Tasigna must be taken on an empty stomach because food can increase the amount of the drug in your blood. This can lead to a higher risk of serious side effects. You should wait at least two hours after a meal before taking your dose and wait at least one hour after your dose before eating again. Following this schedule is critical for safety.

If you miss a dose of Tasigna, you should simply skip the missed dose and take your next dose at its regularly scheduled time. You should not take two doses at the same time or close together to make up for a missed one. Taking extra Tasigna can increase your risk of side effects. Consistency is important, so try to take it as prescribed.

Tasigna requires you to avoid certain foods and drinks, most importantly grapefruit. You should not consume grapefruit, grapefruit juice, or any supplements containing grapefruit extract. These products can increase the levels of Tasigna in your body to dangerous levels. Always follow the dietary instructions provided by your doctor to ensure your safety and the medication’s effectiveness during your treatment with this drug.

While taking Tasigna, your doctor will monitor you closely to manage potential side effects. This involves regular blood tests to check your blood cell counts, liver function, and electrolyte levels like potassium and magnesium. You will also have periodic electrocardiograms (ECGs) to check your heart’s electrical activity. These regular checks help ensure the treatment is both safe and effective for you.

Tasigna can increase the risk of serious heart problems, including a condition called QT prolongation, which affects the heart's rhythm. It can also lead to blockages in arteries, heart attack, and stroke. Your doctor will check your heart health before you start Tasigna and will monitor it regularly during treatment. It is crucial to report any chest pain, dizziness, or shortness of breath to your doctor immediately.

Tasigna may cause hair loss (alopecia) as a side effect in some patients. This is listed as a very common side effect, meaning it can occur in more than one in ten people taking the drug. The extent of hair loss can vary from person to person. If you are concerned about this side effect, you should discuss it with your healthcare provider for management advice.

Tasigna can cause serious harm to an unborn baby, so you should not become pregnant while taking it. Women who are able to become pregnant must use effective contraception during their entire treatment and for at least two weeks after their final dose. If you are planning a pregnancy or become pregnant, you must inform your doctor immediately to discuss the potential risks.

Tasigna capsules should be swallowed whole, but there is an alternative if you cannot. You can open an individual capsule and mix its entire contents with one teaspoon of applesauce. You must eat the mixture immediately. Do not use any other food besides applesauce, and do not store the mixture for later use. This ensures you receive the correct dose of the medication.

Tasigna is a long-term treatment for a chronic condition, and many patients continue taking it for many years. The duration of your treatment depends on how well you respond to the medication and manage any side effects. In some cases, your doctor may consider stopping treatment if you achieve a deep, stable remission. Discontinuation must always be supervised by your doctor.

Tasigna can interact with many other medicines, which can affect how it works or increase your risk of severe side effects. This includes some common prescription drugs, over-the-counter medications, and herbal supplements like St. John's wort. Always provide your doctor with a complete list of all medications and supplements you are taking before you start Tasigna, and before starting any new ones.

Tasigna capsules should be stored at room temperature, below 86°F (30°C). Keep the medicine in its original packaging to protect it from moisture. As with all prescription medications, it is very important to keep Tasigna out of the sight and reach of children and pets. Do not use any capsules that are past their expiration date or if the packaging appears damaged.

Tasigna is approved for use in children with newly diagnosed Philadelphia chromosome-positive CML. The dosage for children is carefully calculated by the doctor based on the child’s body surface area and should not exceed the maximum adult dose. One of the potential side effects in children and adolescents is a slowing of growth, which will be monitored by their healthcare provider.
