Bloxiverz (neostigmine methylsulfate) injection is a cholinesterase inhibitor used after surgery to reverse the effects of non-depolarizing neuromuscular blocking agents.

Dosage of Bloxiverz is based on the patient's weight. The drug is administered intravenously and is injected slowly over a period of at least 1 minute. Bloxiverz may interact with other drugs that may alter the activity of metabolizing enzymes or transporters. Tell your doctor all medications and supplements you use. During pregnancy, Bloxiverz should be used only if needed. It is unknown if this drug passes in breast milk. Consult your doctor before breastfeeding.

SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse reactions to neostigmine methylsulfate are most often attributable to exaggerated pharmacological effects, in particular, at muscarinic receptor sites. The use of an anticholinergic agent, e.g., atropine sulfate or glycopyrrolate, may prevent or mitigate these reactions.

Quantitative adverse event data are available from trials of neostigmine methylsulfate in which 200 adult patients were exposed to the product. The following table lists the adverse reactions that occurred with an overall frequency of 1% or greater.

System Organ Class Adverse Reaction
Cardiovascular Disorders bradycardia, hypotension, tachycardia/heart rate increase
Gastrointestinal Disorders dry mouth, nausea, post-procedural nausea, vomiting
General Disorders and Administration Site Conditions incision site complication, pharyngolaryngeal pain, procedural complication, procedural pain

Skin and Subcutaneous Tissue Disorders pruritus

Post Marketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
