Physical Incompatibility: Since the stability of glycopyrrolate is questionable above a pH of 6.0 do not combine glycopyrrolate injection in the same syringe with Brevital® (methohexital Na); Chloromycetin® (chloramphenicol Na succinate); Dramamine® (dimenhydrinate); Nembutal® (pentobarbital Na); Pentothal® (thiopental Na); Seconal® (secobarbital Na); sodium bicarbonate (Abbott); Valium® (diazepam); Decadron® (dexamethasone Na phosphate); or Talwin® (pentazocine lactate).These mixtures will result in a pH higher than 6.0 and may result in gas production or precipitation.
In Anesthesia: Glycopyrrolate injection is indicated for use as a preoperative antimuscarinic to reduce salivary, tracheobronchial, and pharyngeal secretions; to reduce the volume and free acidity of gastric secretions; and, to block cardiac vagal inhibitory reflexes during induction of anesthesia and intubation.
When indicated, glycopyrrolate injection may be used intraoperatively to counteract surgically or drug-induced or vagal reflexes associated arrhythmias.Glycopyrrolate protects against the peripheral muscarinic effects (e.g., bradycardia and excessive secretions) of cholinergic agents such as neostigmine and pyridostigmine given to reverse the neuromuscular blockade due to non-depolarizing muscle relaxants.
This drug should be used with great caution, if at all, in patients with glaucoma.Exposure to excessive amounts of benzyl alcohol has been associated with toxicity (hypotension, metabolic acidosis), particularly in neonates, and an increased incidence of kernicterus, particularly in small preterm infants.
There have been rare reports of deaths, primarily in preterm infants, associated with exposure to excessive amounts of benzyl alcohol.
The amount of benzyl alcohol from medications is usually considered negligible compared to that received in flush solutions containing benzyl alcohol.
Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered.
The amount of benzyl alcohol at which toxicity may occur is not known.
If the patient requires more than the recommended dosages or other medications containing this preservative, the practitioner must consider the daily metabolic load of benzyl alcohol from these combined sources (see PRECAUTIONS, Pediatric Use).Glycopyrrolate injection may produce drowsiness or blurred vision.
The patient should be cautioned regarding activities requiring mental alertness such as operating a motor vehicle or other machinery or performing hazardous work while taking this drug.In addition, in the presence of fever, high environmental temperature and/or during physical exercise, heat prostration can occur with use of anticholinergic agents including glycopyrrolate (due to decreased sweating), particularly in children and the elderly.Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy.In this instance treatment with glycopyrrolate injection would be inappropriate and possibly harmful.
