2.1 Dosing Information
TAJ PHARMA Hydroxyurea is used alone or in conjunction with other antitumor agents or radiation therapy to treat neoplastic diseases. Individualize treatment based on tumor type, disease state, response to treatment, patient risk factors, and current clinical practice standards.
Base all dosage on the patient’s actual or ideal weight, whichever is less.
TAJ PHARMA Hydroxyurea is a cytotoxic drug. Follow applicable special handling and disposal procedures [see REFERENCES (15)].
Prophylactic administration of folic acid is recommended [see Warnings and Precautions (5.7)].
2.2 Dose Modifications for Toxicity
Monitor for the following and reduce the dose or discontinue TAJ PHARMA Hydroxyurea accordingly:
·         Myelosuppression [see Warnings and Precautions (5.1)].
·         Cutaneous vasculitis [see Warnings and Precautions (5.4)]
Monitor blood counts at least once a week during TAJ PHARMA Hydroxyurea therapy. Severe anemia must be corrected before initiating therapy with TAJ PHARMA Hydroxyurea. Consider dose modifications for other toxicities.
2.3 Dose Modifications for Renal Impairment
Reduce the dose of TAJ PHARMA Hydroxyurea capsules by 50% in patients with measured creatinine clearance of less than 60 mL/min or with end-stage renal disease (ESRD) [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

Capsules:
·         500 mg dark green opaque (cap) printed “724” in white ink/ pink opaque (body) printed “taj” in black ink.
TAJ PHARMA Hydroxyurea capsules are contraindicated in patients who have demonstrated a previous hypersensitivity to TAJ PHARMA Hydroxyurea or any other component of the formulation.
5.1 Myelosuppression
TAJ PHARMA Hydroxyurea causes severe myelosuppression. Treatment with TAJ PHARMA Hydroxyurea should not be initiated if bone marrow function is markedly depressed. Bone marrow suppression may occur, and leukopenia is generally its first and most common manifestation. Thrombocytopenia and anemia occur less often and are seldom seen without a preceding leukopenia.  Bone marrow depression is more likely in patients who have previously received radiotherapy or cytotoxic cancer chemotherapeutic agents; use TAJ PHARMA Hydroxyurea cautiously in such patients.
Evaluate hematologic status prior to and during treatment with TAJ PHARMA Hydroxyurea capsules. Provide supportive care and modify dose or discontinue TAJ PHARMA Hydroxyurea as needed. Recovery from myelosuppression is usually rapid when therapy is interrupted.
5.2 Malignancies
TAJ PHARMA Hydroxyurea is a human carcinogen. In patients receiving long-term TAJ PHARMA Hydroxyurea for myeloproliferative disorders, secondary leukemia has been reported. Skin cancer has also been reported in patients receiving long-term TAJ PHARMA Hydroxyurea. Advise protection from sun exposure and monitor for the development of secondary malignancies.
5.3 Embryo-Fetal Toxicity
Based on the mechanism of action and findings in animals, TAJ PHARMA Hydroxyurea can cause fetal harm when administered to a pregnant woman. TAJ PHARMA Hydroxyurea was embryotoxic and teratogenic in rats and rabbits at doses 0.8 times and 0.3 times, respectively, the maximum recommended human daily dose on a mg/m2 basis.  Advise pregnant women of the potential risk to a fetus [see Use in Specific Populations (8.1)].
Advise females of reproductive potential to use effective contraception during and after treatment with TAJ PHARMA Hydroxyurea capsules for at least 6 months after therapy.  Advise males of reproductive potential to use effective contraception during and after treatment with TAJ PHARMA Hydroxyurea capsules for at least 1 year after therapy [see Use in Specific Populations (8.1, 8.3)].
5.4 Vasculitic Toxicities
Cutaneous vasculitic toxicities, including vasculitic ulcerations and gangrene, have occurred in patients with myeloproliferative disorders during therapy with TAJ PHARMA Hydroxyurea. These vasculitic toxicities were reported most often in patients with a history of, or currently receiving, interferon therapy. If cutaneous vasculitic ulcers occur, institute treatment and discontinue TAJ PHARMA Hydroxyurea capsules.
5.5 Live Vaccinations
Avoid use of live vaccine in patients taking TAJ PHARMA Hydroxyurea capsules. Concomitant use of TAJ PHARMA Hydroxyurea capsules with a live virus vaccine may potentiate the replication of the virus and/or may increase the adverse reaction of the vaccine because normal defense mechanisms may be suppressed by TAJ PHARMA Hydroxyurea capsules. Vaccination with live vaccines in a patient receiving TAJ PHARMA Hydroxyurea capsules may result in severe infection. Patient’s antibody response to vaccines may be decreased. Consider consultation with a specialist.
5.6 Risks with Concomitant Use of Antiretroviral Drugs
Pancreatitis, hepatotoxicity, and peripheral neuropathy have occurred when TAJ PHARMA Hydroxyurea was administered concomitantly with antiretroviral drugs, including didanosine and stavudine [see Drug Interactions (7.1)].
5.7 Radiation Recall
Patients who have received irradiation therapy in the past may have an exacerbation of postirradiation erythema. Monitor for skin erythema in patients who previously received radiation and manage symptomatically.
5.8 Macrocytosis
TAJ PHARMA Hydroxyurea capsules may cause macrocytosis, which is self-limiting, and is often seen early in the course of treatment. The morphologic change resembles pernicious anemia, but is not related to vitamin B12 or folic acid deficiency. This may mask the diagnosis of pernicious anemia. Prophylactic administration of folic acid is recommended.
The following adverse reactions are described in detail in other labeling sections:
·         Myelosuppression [see Warnings and Precautions (5.1)]
·         Malignancies [see Warnings and Precautions (5.2)]
·         Embryo-fetal toxicity [see Warnings and Precautions (5.3)]
·         Vasculitic toxicities [see Warnings and Precautions (5.4)]
·         Risks with concomitant use of antiretroviral drugs [see Warnings and Precautions (5.6)]
·         Radiation recall [see Warnings and Precautions (5.7)]
·         Macrocytosis [see Warnings and Precautions (5.8)]
Postmarketing Experience
The following adverse reactions have been identified during postapproval use of TAJ PHARMA Hydroxyurea capsules.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency.
·         Reproductive System and Breast disorders: azoospermia, and oligospermia
·         Gastrointestinal disorders: stomatitis, nausea, vomiting, diarrhea, and constipation
·         Metabolism and Nutrition disorders: anorexia, tumor lysis syndrome
·         Skin and subcutaneous tissue disorders: maculopapular rash, skin ulceration, dermatomyositis-like skin changes, peripheral and facial erythema, hyperpigmentation, atrophy of skin and nails, scaling, violet papules, and alopecia
·         Renal and urinary disorders: dysuria, elevations in serum uric acid, blood urea nitrogen (BUN), and creatinine levels
·         Nervous system disorders: headache, dizziness, drowsiness, disorientation, hallucinations, and convulsions
·         General disorders: fever, chills, malaise, edema, and asthenia
·         Hepatobiliary disorders: elevation of hepatic enzymes, cholestasis, and hepatitis
·         Respiratory disorders: diffuse pulmonary infiltrates, dyspnea, and pulmonary fibrosis
Adverse reactions observed with combined TAJ PHARMA Hydroxyurea and irradiation therapy are similar to those reported with the use of TAJ PHARMA Hydroxyurea or radiation treatment alone. These effects primarily include bone marrow depression (anemia and leukopenia), gastric irritation, and mucositis. Almost all patients receiving an adequate course of combined TAJ PHARMA Hydroxyurea and irradiation therapy will demonstrate concurrent leukopenia. Platelet depression (<100,000 cells/mm3) has occurred in the presence of marked leukopenia. TAJ PHARMA Hydroxyurea capsules may potentiate some adverse reactions usually seen with irradiation alone, such as gastric distress and mucositis.
7.1 Increased Toxicity with Concomitant Use of Antiretroviral Drugs
Pancreatitis
In patients with HIV infection during therapy with TAJ PHARMA Hydroxyurea and didanosine, with or without stavudine, fatal and nonfatal pancreatitis have occurred. TAJ PHARMA Hydroxyurea is not indicated for the treatment of HIV infection; however, if patients with HIV infection are treated with TAJ PHARMA Hydroxyurea, and in particular, in combination with didanosine and/or stavudine, close monitoring for signs and symptoms of pancreatitis is recommended. Permanently discontinue therapy with TAJ PHARMA Hydroxyurea in patients who develop signs and symptoms of pancreatitis.
Hepatotoxicity
Hepatotoxicity and hepatic failure resulting in death have been reported during postmarketing surveillance in patients with HIV infection treated with TAJ PHARMA Hydroxyurea and other antiretroviral drugs. Fatal hepatic events were reported most often in patients treated with the combination of TAJ PHARMA Hydroxyurea, didanosine, and stavudine. Avoid this combination.
Peripheral Neuropathy
Peripheral neuropathy, which was severe in some cases, has been reported in patients with HIV infection receiving TAJ PHARMA Hydroxyurea in combination with antiretroviral drugs, including didanosine, with or without stavudine.
7.2 Test Interference
Interference with Uric Acid, Urea, or Lactic Acid Assays
Studies have shown that there is an analytical interference of TAJ PHARMA Hydroxyurea with the enzymes (urease, uricase, and lactate dehydrogenase) used in the determination of urea, uric acid, and lactic acid, rendering falsely elevated results of these in patients treated with TAJ PHARMA Hydroxyurea.
8.1 Pregnancy
Risk Summary
TAJ PHARMA Hydroxyurea capsules can cause fetal harm based on findings from animal studies and the drug’s mechanism of action [see Clinical Pharmacology (12.1)]. There are no data with TAJ PHARMA Hydroxyurea capsules use in pregnant women to inform a drug-associated risk. In animal reproduction studies, administration of TAJ PHARMA Hydroxyurea to pregnant rats and rabbits during organogenesis produced embryotoxic and teratogenic effects at doses 0.8 times and 0.3 times, respectively, the maximum recommended human daily dose on a mg/m2basis (see Data). Advise women of the potential risk to a fetus and to avoid becoming pregnant while being treated with TAJ PHARMA Hydroxyurea capsules.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data
Animal Data
TAJ PHARMA Hydroxyurea has been demonstrated to be a potent teratogen in a wide variety of animal models, including mice, hamsters, cats, miniature swine, dogs, and monkeys at doses within 1-fold of the human dose given on a mg/m2 basis. TAJ PHARMA Hydroxyurea is embryotoxic and causes fetal malformations (partially ossified cranial bones, absence of eye sockets, hydrocephaly, bipartite sternebrae, missing lumbar vertebrae) at 180 mg/kg/day (about 0.8 times the maximum recommended human daily dose on a mg/m2basis) in rats and at 30 mg/kg/day (about 0.3 times the maximum recommended human daily dose on a mg/m2 basis) in rabbits. Embryotoxicity was characterized by decreased fetal viability, reduced live litter sizes, and developmental delays. TAJ PHARMA Hydroxyurea crosses the placenta. Single doses of ≥375 mg/kg (about 1.7 times the maximum recommended human daily dose on a mg/m2 basis) to rats caused growth retardation and impaired learning ability.
8.2 Lactation
Risk Summary
TAJ PHARMA Hydroxyurea is excreted in human milk. Because of the potential for serious adverse reactions in a breastfed infant from TAJ PHARMA Hydroxyurea, including carcinogenicity, discontinue breastfeeding during treatment with TAJ PHARMA Hydroxyurea capsules.
8.3 Females and Males of Reproductive Potential
Pregnancy Testing
Verify the pregnancy status of females of reproductive potential prior to initiating TAJ PHARMA Hydroxyurea capsules therapy.
Contraception
Females
TAJ PHARMA Hydroxyurea capsules can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during and after treatment with TAJ PHARMA Hydroxyurea capsules for at least 6 months after therapy. Advise females to immediately report pregnancy.
Males
TAJ PHARMA Hydroxyurea capsules may damage spermatozoa and testicular tissue, resulting in possible genetic abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during and after treatment with TAJ PHARMA Hydroxyurea capsules for at least 1 year after therapy [see Nonclinical Toxicology (13.1)].
Infertility
Males
Based on findings in animals and humans, male fertility may be compromised by treatment with TAJ PHARMA Hydroxyurea capsules. Azoospermia or oligospermia, sometimes reversible, has been observed in men. Inform male patients about the possibility of sperm conservation before the start of therapy [see Adverse Reactions (6) and Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
Safety and effectiveness in pediatric patients have not been established.
8.5 Geriatric Use
Elderly patients may be more sensitive to the effects of TAJ PHARMA Hydroxyurea, and may require a lower dose regimen. TAJ PHARMA Hydroxyurea is excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Dosage and Administration (2.3)].
8.6 Renal Impairment
The exposure to TAJ PHARMA Hydroxyurea is higher in patients with creatinine clearance of less than 60 mL/min or in patients with end-stage renal desease (ESRD). Reduce dosage and closely monitor the hematologic parameters when TAJ PHARMA Hydroxyurea capsules is to be administered to these patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
There are no data that support specific guidance for dosage adjustment in patients with hepatic impairment. Close monitoring of hematologic parameters is advised in these patients.
Acute mucocutaneous toxicity has been reported in patients receiving TAJ PHARMA Hydroxyurea at dosages several times the therapeutic dose. Soreness, violet erythema, edema on palms and soles followed by scaling of hands and feet, severe generalized hyperpigmentation of the skin, and stomatitis have also been observed.

12.1 Mechanism of Action
The precise mechanism by which TAJ PHARMA Hydroxyurea produces its antineoplastic effects cannot, at present, be described.  However, the reports of various studies in tissue culture in rats and humans lend support to the hypothesis that TAJ PHARMA Hydroxyurea causes an immediate inhibition of DNA synthesis by acting as a ribonucleotide reductase inhibitor, without interfering with the synthesis of ribonucleic acid or of protein. This hypothesis explains why, under certain conditions, TAJ PHARMA Hydroxyurea may induce teratogenic effects.
Three mechanisms of action have been postulated for the increased effectiveness of concomitant use of TAJ PHARMA Hydroxyurea therapy with irradiation on squamous cell (epidermoid) carcinomas of the head and neck. In vitro studies utilizing Chinese hamster cells suggest that TAJ PHARMA Hydroxyurea (1) is lethal to normally radioresistant S-stage cells, and (2) holds other cells of the cell cycle in the G1 or pre-DNA synthesis stage where they are most susceptible to the effects of irradiation. The third mechanism of action has been theorized on the basis of in vitro studies of HeLa cells. It appears that TAJ PHARMA Hydroxyurea, by inhibition of DNA synthesis, hinders the normal repair process of cells damaged but not killed by irradiation, thereby decreasing their survival rate; RNA and protein synthesis have shown no alteration.
12.3 Pharmacokinetics
Absorption
Following oral administration of TAJ PHARMA Hydroxyurea capsules, TAJ PHARMA Hydroxyurea reaches peak plasma concentrations in 1 to 4 hours. Mean peak plasma concentrations and AUCs increase more than proportionally with increase of dose.
There are no data on the effect of food on the absorption of TAJ PHARMA Hydroxyurea.
Distribution
TAJ PHARMA Hydroxyurea distributes throughout the body with a volume of distribution approximating total body water.
TAJ PHARMA Hydroxyurea concentrates in leukocytes and erythrocytes.
Metabolism
Up to 60% of an oral dose undergoes conversion through saturable hepatic metabolism and a minor pathway of degradation by urease found in intestinal bacteria.
Excretion
In patients with sickle cell anemia, the mean cumulative urinary recovery of TAJ PHARMA Hydroxyurea was about 40% of the administered dose.
Specific Populations
Renal Impairment
The effect of renal impairment on the pharmacokinetics of TAJ PHARMA Hydroxyurea was assessed in adult patients with sickle cell disease and renal impairment. Patients with normal renal function (creatinine clearance [CrCl] >80 mL/min), mild (CrCl 50 to 80 mL/min), moderate (CrCl =30 to <50 mL/min), or severe (<30 mL/min) renal impairment received a single oral dose of 15 mg/kg TAJ PHARMA Hydroxyurea.  Patients with ESRD received two doses of 15 mg/kg separated by 7 days; the first was given following a 4-hour hemodialysis session, the second prior to hemodialysis. The exposure to TAJ PHARMA Hydroxyurea (mean AUC) in patients with CrCl <60 mL/min and those with ESRD was 64% higher than in patients with normal renal function (CrCl >60 mL/min). Reduce the dose of TAJ PHARMA Hydroxyurea capsules when it is administered to patients with creatinine clearance of <60 mL/min or with ESRD following hemodialysis [see Dosage and Administration (2.3) and Use in Specific Populations (8.6)].
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Conventional long-term studies to evaluate the carcinogenic potential of TAJ PHARMA Hydroxyurea capsules have not been performed. However, intraperitoneal administration of 125 to 250 mg/kg TAJ PHARMA Hydroxyurea (about 0.6 to 1.2 times the maximum recommended human oral daily dose on a mg/m2 basis) thrice weekly for 6 months to female rats increased the incidence of mammary tumors in rats surviving to 18 months compared to control. TAJ PHARMA Hydroxyurea is mutagenic in vitro to bacteria, fungi, protozoa, and mammalian cells. TAJ PHARMA Hydroxyurea is clastogenic in vitro (hamster cells, human lymphoblasts) and in vivo(SCE assay in rodents, mouse micronucleus assay). TAJ PHARMA Hydroxyurea causes the transformation of rodent embryo cells to a tumorigenic phenotype.
TAJ PHARMA Hydroxyurea administered to male rats at 60 mg/kg/day (about 0.3 times the maximum recommended human daily dose on a mg/m2 basis) produced testicular atrophy, decreased spermatogenesis, and significantly reduced their ability to impregnate females.
