Medically reviewed by Drugs.com. Last updated on Sep 26, 2023.

Warning

Intravenous route (Solution)

For intravenous use only; fatal if given by other routes. To reduce the potential for fatal medication errors due to incorrect route of administration proper dilution, product labeling and packaging is necessary. Intravenous needle or catheter must be properly positioned before any vinCRIStine is injected, as leakage into the surrounding tissue may cause considerable irritation. If extravasation occurs, the injection should be discontinued immediately, and any remaining portion of the dose should then be introduced into another vein. Local injection of hyaluronidase and the application of moderate heat to the area of leakage help disperse the drug and are thought to minimize discomfort and the possibility of cellulitis.

Musculoskeletal

Frequency not reported: Neurotoxicity is the most common dose-limiting side effect of this drug. Frequently, there is a sequence to the development of neuromuscular side effects. Initially, only sensory impairment and paresthesia

may develop. With continued treatment, neuritic pain and later, motor difficulties may occur. Loss of deep-tendon reflexes, foot drop, wrist drop, ataxia, and paralysis have been reported with continued administration. Cranial nerve manifestations, including isolated paresis and/or paralysis of muscles controlled by cranial motor nerves, may occur in the absence of motor impairment elsewhere; extra-ocular and laryngeal muscles are those most commonly involved. Numbness of the fingers and toes, atrophy, cramps, slapping gait, and difficulty in walking or inability to walk, may occur. Jaw pain, pharyngeal pain, parotid gland pain, bone pain, back pain, limb pain, and myalgias have been reported; pain in these areas may be severe.^[Ref]

Psychiatric

Frequency not reported: Depression, agitation, insomnia, hallucinations^[Ref]

General
