Indications
- Promacta is indicated for the treatment of thrombocytopenia in patients with chronic immune thrombocytopenia (ITP) who have had an inadequate response to other treatments.
- It is prescribed to help increase platelet counts in patients with ITP, reducing the risk of bleeding episodes and the need for platelet transfusions.
- Promacta may also be used to treat thrombocytopenia in patients with chronic hepatitis C virus (HCV) infection to allow the initiation and maintenance of interferon-based therapy.
Dosage and administration
- The recommended dosage of Promacta for the treatment of chronic immune thrombocytopenia (ITP) is individualized based on the patient’s platelet count and response to treatment.
- Typically, the initial dosage of Promacta is 50 milligrams (mg) orally once daily.
- The dosage may be adjusted by the healthcare provider based on the patient’s platelet count, with a maximum recommended dosage of 75 mg once daily.
- Promacta should be taken on an empty stomach at least 1 hour before or 2 hours after eating food or consuming dairy products or calcium-fortified beverages.
- Swallow the tablet whole with a glass of water. Do not crush, chew, or break the tablet.
- It is important to take Promacta regularly to achieve and maintain optimal platelet counts.
- If a dose of Promacta is missed, take it as soon as remembered, unless it is almost time for the next scheduled dose. Do not double the dose to catch up.
- If you have any questions or concerns about the dosage or administration of Promacta, consult your healthcare provider.
