Medicine Overview of Leukin 50mg Tablet

Introduction

Leukin 50 is used in the treatment of blood cancer. It shows its working by decreasing the number of red blood cells, which is produced by the body.

Leukin 50 can be taken with or without food or you can have it one hour before or 2 hours after the meal. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to.

The most common side effects of this medicine include nausea, vomiting, rash, diarrhea, and loss of appetite. This medicine may reduce the number of blood cells (decrease red blood and white blood cells) in your blood, thereby, increasing the susceptibility to infections. Regular blood tests are required to check your blood cells along with heart, liver, and blood uric acid levels. You have to avoid driving or attention seeking activity if you experience dizziness while taking this medicine.

Before taking it, tell your doctor if you have heart disease, liver, or kidney problems or are taking any medicines to treat infections. Many other medicines can affect, or be affected by, this medicine so let your doctor know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. The use of effective contraception by both males and females during treatment is important to avoid pregnancy.

Acute Lymphatic Leukemia
Induction: 2.5 mg/kg PO qDay; usually 100-200 mg PO qDay in average adult (other agents preferred)
May increase by 5 mg/kg/day after 4 weeks
Maintenance: 1.5-2.5 mg/kg PO qDay

Mode of Action
Mercaptopurine is a purine antagonist which is converted intracellularly into its active nucleotides, including thioinosinic acid. The nucleotides inhibit several reactions which ultimately interferes with nucleic acid synthesis and prevents the formation of RNA and DNA.
Precaution

Hepatic or renal dysfunction; monitor hepatic function periodically. Mercaptopurine is potentially carcinogenic. Thiopurine S-methyl transferase (TPMT) deficiency; porphyria.
