Crisvin® 1mg/1ml Injection (Vincristine) – Chemotherapy (Rx)

Quick answer: Crisvin 1mg (vincristine) is a vinca alkaloid chemotherapy for leukaemia, lymphoma and several childhood cancers. A trained doctor or nurse gives it only into a vein, never into the spine. MedHub supplies it on prescription and delivers across Pakistan in a cold-chain box.

For patients and families

What is Crisvin 1mg?

Crisvin 1mg is a clear liquid in a 1 ml vial, made in Pakistan by Pharmasol. Its active ingredient, vincristine, comes from the periwinkle plant family and belongs to the vinca alkaloids. It stops cancer cells from splitting into new cells, which slows the disease down.

What is it used for?

Vincristine is part of many standard treatment plans, always combined with other medicines. Oncologists use it for:

• Acute leukaemia: especially acute lymphoblastic leukaemia in children and adults.
• Hodgkin and non-Hodgkin lymphoma: as one part of a multi-drug regimen.
• Childhood solid tumours: such as neuroblastoma, Wilms tumour and rhabdomyosarcoma.

Your oncologist chooses the regimen after reviewing your diagnosis, blood tests and treatment history.

How is it given?

This medicine goes into a vein only. A trained doctor or nurse gives it at a hospital or day-care unit, and the team checks the drip site closely because the liquid can damage skin if it leaks outside the vein. It must never go into the spine or the fluid around the spinal cord, because that can be fatal. Your doctor decides the dose and the schedule.

Common side effects

• Constipation and stomach cramps
• Tingling, numbness or weakness in the fingers and toes
• Hair thinning, which usually grows back
• Jaw pain, tiredness and low blood counts

Tell your care team straight away if you have a fever, severe stomach pain, no bowel movement for several days, trouble walking, drooping eyelids, or pain, redness or swelling where the drip goes in.

Storage

Keep the vial in a fridge at 2–8°C, inside its box and away from light. Hospitals normally store it for you. Read how we keep medicines cold during delivery to see how we protect the vials on the way.
