Uses for neostigmine
Neostigmine injection is used to treat a muscle disease called myasthenia gravis.
Neostigmine injection is also used to prevent or treat certain kidney or intestinal problems. Neostigmine is also given after surgery to help reverse the effects of certain types of medicines that have been used to relax the muscles.
Neostigmine is available only with your doctor's prescription.
Before using neostigmine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For neostigmine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to neostigmine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of neostigmine injection in children. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of Bloxiverz™ in children. However, infants and small children may be more sensitive to the effects of neostigmine.
No information is available on the relationship of age to the effects of neostigmine injection in geriatric patients.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of Bloxiverz™ in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution for patients receiving Bloxiverz™.
