Sprycel (dasatinib) is a prescription drug that’s used to treat certain types of leukemia. The drug comes as an oral tablet that you usually take once per day.

Sprycel is prescribed to adults and certain children to treat specific types of leukemia that are Philadelphia chromosome positive.* These include acute lymphoblastic leukemia and chronic myeloid leukemia.

* The Philadelphia chromosome is an abnormal change in genes within cancer cells. If your leukemia is Philadelphia positive, it means your body has this change.

The active ingredient in Sprycel is dasatinib. (An active ingredient is what makes a drug work.)

Sprycel belongs to a group of drugs called kinase inhibitors.

What are the usual dosages of Sprycel in adults?

Your doctor will likely start by prescribing a low dosage and adjust it over time to reach the right amount for you. They’ll ultimately prescribe the smallest dosage that provides the desired effect.

The information below describes dosages that are commonly prescribed or recommended. But be sure to follow the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs.

Dosage for acute lymphoblastic leukemia (ALL)

Sprycel is prescribed to treat ALL in certain situations. The usual starting dosage of Sprycel for ALL in adults is 140 mg. You’ll take Sprycel once per day, either in the morning or in the evening.

Your doctor will monitor to determine how your body is responding to treatment and adjust your dosage if needed. The maximum dosage of Sprycel for adults with ALL is 180 mg once per day.

Dosage for chronic myeloid leukemia (CML)

Sprycel is prescribed to treat CML in certain situations. For adults, the usual starting dosage of Sprycel depends on the phase of CML.

For the chronic (first) phase, the usual starting dosage is 100 mg. For the accelerated (second) phase and the blast (third) phase, the usual starting dosage is 140 mg. For any phase of CML, you’ll take Sprycel once per day in the morning or evening.

Your doctor will monitor to determine how your body is responding to treatment and adjust your dosage if needed. For adults with chronic phase CML, the maximum dosage of Sprycel is 140 mg once per day. For adults with accelerated phase or blast phase CML, the maximum dosage is 180 mg once per day.

What’s the dosage of Sprycel for children?

Sprycel is prescribed to treat ALL and CML in certain children. Among other factors, children must be age 1 year or older. Dosage is based on the child’s weight in kilograms (kg). For reference, 1 kg is about 2.2 pounds (lb).

The following table includes the recommended starting dosages of Sprycel for children with ALL or CML.

Body weight in kgApproximate body weight in lbStarting dosage
10 kg to less than 20 kg22 lb to less than 44 lb40 mg once per day in the morning or evening
20 kg to less than 30 kg44 lb to less than 66 lb60 mg once per day in the morning or evening
30 kg to less than 45 kg66 lb to less than 99 lb70 mg once per day in the morning or evening
45 kg or more99 lb or more100 mg once per day in the morning or evening

Your child’s doctor will monitor to determine how your child’s body is responding to treatment. If needed, the doctor may adjust your child’s dosage. For children with ALL, the maximum dosage of Sprycel is 100 mg once per day. For children with CML, the maximum dosage is 120 mg once per day. But for both ALL and CML, the maximum dosage for a child still depends on their weight.

For an example of dosage, assume a doctor prescribes Sprycel for a child who’s not taking other medications. The child weighs 35 kg, which is about 77 lb. The child’s dosage would be 70 mg once per day to be taken in the morning or evening.

To learn more about Sprycel’s dosage for children, talk with your child’s doctor or a pharmacist.

Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.

If you miss a dose of Sprycel, skip the missed dose. Then take your next dose at its usual time. If you have questions about this, talk with your doctor or pharmacist.
