IM IV (Children): 4–10 mcg/kg/dose every 3–4 hr.
PO (Children): 40–100 mcg/kg/dose 3–4 times/day.
IV (Adults and Children): 200 mcg for each 1 mg of neostigmine or 5 mg of pyridostigmine given at the same time.
PO (Adults): 1–2 mg 2–3 times daily. An additional 2 mg may be given at bedtime; may be ↓ to 1 mg twice daily (not to exceed 8 mg/day). Orally disintegrating tablet (Dartisla ODT)– 1.7 mg 2–3 times daily (1.7–mg orally disintegrating tablet = 2–mg regular oral tablet).

In Combination with: neostigmine (Prevduo). See combination drugs.
- Assess heart rate, BP, and respiratory rate before and periodically during parenteral therapy.
- Monitor intake and output ratios in geriatric or surgical patients; glycopyrrolate may cause urinary retention. Instruct patient to void before parenteral administration.
- Assess patient routinely for abdominal distention and auscultate for bowel sounds. If constipation becomes a problem, increasing fluids and adding bulk to the diet may help alleviate the constipating effects of the drug.
- Periodic intraocular pressure determinations should be made for patients receiving long-term therapy.
Pedi: Monitor amount and frequency of drooling periodically during therapy.
- Assess for hyperexcitability, a paradoxical response that may occur in children.
Lab Test Considerations:
Antagonizes effects of pentagastrin and histamine during the gastric acid secretion test. Avoid administration for 24 hr preceding the test.

- Do not administer cloudy or discolored solution.

- Advise patient to change positions slowly to minimize the effects of drug-induced orthostatic hypotension.
- Caution patient to avoid extremes of temperature. This medication decreases the ability to sweat and may increase the risk of heat stroke.
