Other uses for this medicine

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Is dasatinib available as a generic drug?

GENERIC AVAILABLE: No

Which drugs or supplements interact with dasatinib?

The blood concentration of dasatinib may be increased by several drugs that reduce its break down by liver enzymes. Increased blood concentrations of dasatinib may increase the occurrence of adverse effects. Examples include ketoconazole, itraconazole (Sporanox), clarithromycin (Biaxin), atazanavir (Reyataz), indinavir (Crixivan), nelfinavir (Viracept), ritonavir (Norvir), saquinavir (Invirase), telithromycin (Ketek), voriconazole (Vfend), and grapefruit juice. A dose reduction should be considered if there are no alternative medications that will not interact with dasatinib, for example a reduction in dose from 100 mg to 20 mg or 140 mg to 40 mg daily.

Certain drugs decrease the concentration of dasatinib resulting in decreased blood levels and possibly reduced effect. Examples include dexamethasone, carbamazepine, phenobarbital, rifampin, phenobarbital, and St John's Wort. A dose increase should be considered if dasatinib is combined with such drugs.

Drugs that reduce production of acid in the stomach reduce the absorption of dasatinib. Examples include proton pump inhibitors (PPIs) such as omeprazole (Prilosec) and H2 blocking drugs such as famotidine (Pepcid). Antacids used 2 hours before or after administration of dasatinib are reasonable alternatives to drugs that reduce the production of acid in the stomach.

Dasatinib increases the blood concentration of simvastatin (Zocor) by reducing the activity of enzymes that break down simvastatin in the liver. This may increase the side effects of simvastatin. Dasatinib may interact with other drugs that are broken down in a similar way as simvastatin.

Uses For Sprycel

Dasatinib is used to treat different types of leukemia. Leukemia is a type of cancer where the body makes too many abnormal white blood cells. It belongs to the general group of medicines known as antineoplastics or cancer medicines. Dasatinib interferes with the growth of cancer cells, which are eventually destroyed by the body.

This medicine is available only with your doctor's prescription.

Drug Interactions

Drugs That May Increase Dasatinib Plasma Concentrations

CYP3A4 Inhibitors: Dasatinib is a CYP3A4 substrate. In a trial of 18 patients with solid tumors, 20-mg Sprycel once daily coadministered with 200 mg of ketoconazole twice daily increased the dasatinib Cmax and AUC by four- and five-fold, respectively. Concomitant use of Sprycel and drugs that inhibit CYP3A4 may increase exposure to dasatinib and should be avoided. In patients receiving treatment with Sprycel, close monitoring for toxicity and a Sprycel dose reduction should be considered if systemic administration of a potent CYP3A4 inhibitor cannot be avoided [see Dosage and Administration (2.1)].

Drugs That May Decrease Dasatinib Plasma Concentrations

CYP3A4 Inducers: When a single morning dose of Sprycel was administered following 8 days of continuous evening administration of 600 mg of rifampin, a potent CYP3A4 inducer, the mean Cmax and AUC of dasatinib were decreased by 81% and 82%, respectively. Alternative agents with less enzyme induction potential should be considered. If Sprycel must be administered with a CYP3A4 inducer, a dose increase in Sprycel should be considered [see Dosage and Administration (2.1)].

Antacids: Nonclinical data demonstrate that the solubility of dasatinib is pH dependent. In a trial of 24 healthy subjects, administration of 30 mL of aluminum hydroxide/magnesium hydroxide 2 hours prior to a single 50-mg dose of Sprycel was associated with no relevant change in dasatinib AUC; however, the dasatinib Cmax increased 26%. When 30 mL of aluminum hydroxide/magnesium hydroxide was administered to the same subjects concomitantly with a 50-mg dose of Sprycel, a 55% reduction in dasatinib AUC and a 58% reduction in Cmax were observed. Simultaneous administration of Sprycel with antacids should be avoided. If antacid therapy is needed, the antacid dose should be administered at least 2 hours prior to or 2 hours after the dose of Sprycel.

H2 Antagonists/Proton Pump Inhibitors: Long-term suppression of gastric acid secretion by H2 antagonists or proton pump inhibitors (e.g., famotidine and omeprazole) is likely to reduce dasatinib exposure. In a trial of 24 healthy subjects, administration of a single 50-mg dose of Sprycel 10 hours following famotidine reduced the AUC and Cmax of dasatinib by 61% and 63%, respectively. In a trial of 14 healthy subjects, administration of a single 100-mg dose of Sprycel 22 hours following a 40-mg omeprazole dose at steady state reduced the AUC and Cmax of dasatinib by 43% and 42%, respectively. The concomitant use of H2 antagonists or proton pump inhibitors with Sprycel is not recommended. The use of antacids (at least 2 hours prior to or 2 hours after the dose of Sprycel) should be considered in place of H2 antagonists or proton pump inhibitors in patients receiving Sprycel therapy.

Drugs That May Have Their Plasma Concentration Altered By Dasatinib

CYP3A4 Substrates: Single-dose data from a trial of 54 healthy subjects indicate that the mean Cmax and AUC of simvastatin, a CYP3A4 substrate, were increased by 37% and 20%, respectively, when simvastatin was administered in combination with a single 100-mg dose of Sprycel. Therefore, CYP3A4 substrates known to have a narrow therapeutic index such as alfentanil, astemizole, terfenadine, cisapride, cyclosporine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, or ergot alkaloids (ergotamine, dihydroergotamine) should be administered with caution in patients receiving Sprycel.

How should I take Sprycel?

Take Sprycel exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

You may take the medicine with or without food. Take the medicine at the same time each day.

Do not crush, chew, or break a Sprycel tablet. Swallow it whole.

Do not use a pill that has been accidentally broken. The medicine from a crushed or broken pill can be dangerous if it gets in your eyes, mouth, or nose, or on your skin. If this occurs, wash your skin with soap and water or rinse your eyes with water. Ask your doctor or pharmacist how to safely handle and dispose of a broken tablet or capsule.

Sprycel can lower blood cells that help your body fight infections and help your blood to clot. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results of these tests.

Do not change your dose or stop using Sprycel without your doctor's advice.

Store at room temperature away from moisture and heat.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

What should I avoid while taking Sprycel?

Grapefruit and grapefruit juice may interact with dasatinib and lead to unwanted side effects. Avoid the use of grapefruit products while taking Sprycel.

Avoid taking an antacid within 2 hours before or after you take Sprycel. Some antacids can make it harder for your body to absorb dasatinib.

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Dasatinib can pass into body fluids (urine, feces, vomit). Caregivers should wear rubber gloves while cleaning up a patient's body fluids, handling contaminated trash or laundry or changing diapers. Wash ands before and after removing gloves. Wash soiled clothing and linens separately from other laundry.
