Vincristine® Injection for Cancer Treatment

Vincristine is a vinca alkaloid chemotherapy used in many cancers. This page explains access, clinic use, and storage, with US shipping from Canada and options for those without insurance. You will also find safety notes to discuss with your oncology team.

What Vincristine Is and How It Works

Vincristine® is an antineoplastic medicine from the vinca alkaloid class. It binds to tubulin, inhibits microtubule assembly, and arrests dividing cells during mitosis. The mechanism is cell cycle–specific and primarily affects rapidly proliferating tissue. Therapy is prepared and given by trained professionals in controlled settings to ensure safe handling and administration. Generic Vincristine Injection is indicated within multi‑agent regimens for hematologic and solid tumors as reflected on approved labeling. CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.

This therapy must only be given intravenously. Intrathecal administration is contraindicated and can be fatal. The treatment is commonly combined with complementary agents to target malignant cells through different pathways. Labeling outlines compatible diluents, recommended administration techniques, and precautions to minimize local tissue injury.

Who It’s For

This medicine is used as part of combination therapy for acute leukemia, Hodgkin lymphoma, non‑Hodgkin lymphoma, and selected pediatric solid tumors such as Wilms tumor and rhabdomyosarcoma. In adults, it may be included in protocol‑based regimens for other sensitive malignancies. People with significant pre‑existing neuropathy, severe hepatic impairment, or known hypersensitivity to any component may not be candidates. It should not be used during pregnancy unless the potential benefit justifies potential risks; breastfeeding is not recommended during treatment. Intrathecal use is strictly prohibited.

Dosage and Usage

Dosing follows established protocols. In many adult regimens, dose is calculated by body surface area and given once each week, with a maximum single dose specified on the label. Pediatric dosing is weight‑ or surface area–based. Administration is by slow intravenous injection or short infusion into a running IV line, prepared by pharmacy staff trained in hazardous drug compounding. Your prescriber determines the schedule, any holds between cycles, and supportive medicines such as antiemetics and laxatives.

Because this treatment is a vesicant, reliable venous access is essential. Extravasation may cause local pain, swelling, or tissue damage; report symptoms during administration immediately. Infusion lines are typically flushed per institutional procedures. Bowel regimens may be considered to reduce the risk of severe constipation or ileus; ask your prescriber what is appropriate for you. Do not self‑administer or attempt to adjust any dose.

Strengths and Forms

Vincristine Sulfate IV vials are supplied as preservative‑free single‑dose presentations suitable for preparation in a sterile pharmacy setting. Common presentations include:

• 1 mg/mL single‑dose vial
• 2 mg/2 mL single‑dose vial

Exact pack sizes and manufacturers may vary. Availability can differ by province and dispensing pharmacy. Your clinic or dispensing pharmacy selects an appropriate presentation based on the prescribed dose and current supply.

Missed Dose and Timing

If a scheduled dose is deferred due to lab results, intercurrent illness, or access issues, your care team will advise when to resume. Do not take extra doses to make up for a missed appointment. Contact your oncology clinic promptly if you miss or are late to a visit; the team will arrange rescheduling and determine if any monitoring is required before the next administration.

Storage and Travel Basics

Unopened vials are stored according to the product label, typically at controlled room temperature and protected from light in the original carton. Keep out of reach of children and away from moisture. Do not freeze. If your prescriber instructs you to supply vials to the infusion center, retain them in their packaging and bring them directly to the clinic on the day of treatment. Avoid leaving vials in a vehicle or in direct sunlight.

For travel, carry copies of your prescription and clinic contact details. Pack medicines securely in a rigid container to prevent breakage. Keep products with you rather than in checked luggage to reduce exposure to extreme temperatures. If a vial is damaged or leaking, do not handle it; contact the dispensing pharmacy or your clinic for instructions.

Benefits

• Well‑characterized microtubule inhibition within multi‑drug cancer regimens
• Once‑weekly administration in many protocols simplifies scheduling
• Preservative‑free single‑dose vials support precise dose preparation
• Broad compatibility with guideline‑supported combination protocols
• Supplied in formats suitable for sterile pharmacy compounding

Benefits depend on the disease setting, concomitant agents, and overall treatment plan determined by your oncology team. Discuss regimen goals and monitoring plans before starting.

Side Effects and Safety

• Numbness or tingling in hands or feet
• Constipation, abdominal cramps, or decreased bowel movements
• Nausea, vomiting, or reduced appetite
• Hair loss
• Jaw pain, muscle weakness, or difficulty walking
• Mouth sores
• Injection site irritation
• Fatigue

Serious effects can include severe neurotoxicity, bowel obstruction or ileus, seizures, low blood sodium from SIADH, breathing problems, and severe infection. Report neuropathic symptoms, severe constipation, abdominal swelling, or urinary retention urgently. This drug must never be given by the intrathecal route. Your team will monitor labs, neurological status, and overall tolerance across cycles and adjust the plan as clinically indicated.

Drug Interactions and Cautions

This treatment is metabolized mainly by CYP3A and is a P‑glycoprotein substrate. Potent CYP3A inhibitors can raise exposure and toxicity; examples include azole antifungals, certain macrolide antibiotics, and some HIV protease inhibitors. Strong inducers such as rifampin can lower levels. Concomitant use with other neurotoxic agents may increase neuropathy risk. Phenytoin exposure can decrease with vinca alkaloids, potentially reducing seizure control. Live vaccines are generally avoided during cytotoxic therapy. Use caution in hepatic impairment; your prescriber will consult the label for specific guidance.

What to Expect Over Time

Early cycles may bring constipation, reduced appetite, or tingling in the fingers and toes. Neuropathic symptoms can accumulate with continued dosing and may prompt schedule adjustments determined by your prescriber. Blood tests and clinical assessments guide treatment over successive cycles. Share new symptoms promptly, keep an updated medication list, and attend all laboratory and clinic visits to support safe care.

Compare With Alternatives

Oncology regimens often combine agents with complementary mechanisms. Anthracyclines such as Doxorubicin act through DNA intercalation and topoisomerase inhibition. Alkylating agents like Leukeran contribute cytotoxic effects via DNA cross‑linking. Selection depends on diagnosis, stage, prior therapy, and overall health. Your prescriber will align the protocol with disease biology and treatment goals.

Availability and Substitutions

Supply can vary by manufacturer and lot. If a specific vial size is out of stock, your prescriber may recommend an alternative presentation or adjust the plan to use an equivalent amount. If your care team directs you to supply this medicine for infusion, you can place a Vincristine refill online ahead of the next cycle to reduce delays. When a product is unavailable, your clinic may suggest an alternative agent that fits your regimen.

Patient Suitability and Cost-Saving Tips

Good candidates are those whose condition aligns with labeled indications and who can attend frequent monitoring visits. People with marked peripheral neuropathy, uncontrolled infection, or severe liver dysfunction may not be suitable. Pregnancy and breastfeeding are generally discouraged during therapy; discuss family planning before starting. To manage expenses, ask whether multiple vials for several weeks can be dispensed together, where appropriate, to reduce repeated dispensing fees. Schedule reminders for upcoming cycles and coordinate deliveries so your clinic has product available before your visit. Keep an updated medication list and share new over‑the‑counter products or supplements with your prescriber.
