Applies to metoclopramide: oral solution, oral tablet, oral tablet disintegrating
Other dosage forms:
Oral route (Tablet)
Metoclopramide can cause tardive dyskinesia, a serious movement disorder that is often irreversible. The risk of developing tardive dyskinesia increases with duration of treatment and total cumulative dose. Discontinue metoclopramide in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide is stopped. Avoid treatment with Reglan for longer than 12 weeks because of the increased risk of developing TD with longer-term use.
Oral route (Tablet, Disintegrating; Solution)
Metoclopramide treatment can cause tardive dyskinesia, a serious movement disorder that is often irreversible. Risk is increased with duration of treatment and total cumulative dose. Discontinue metoclopramide therapy in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia, although symptoms may lessen or resolve after metoclopramide discontinuation. Prolonged treatment with metoclopramide (greater than 12 weeks) should be avoided in all but rare cases where therapeutic benefit outweighs the risks.
Along with its needed effects, metoclopramide may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur while taking metoclopramide:
Incidence not known
Get emergency help immediately if any of the following symptoms of overdose occur while taking metoclopramide:
Symptoms of overdose
Some side effects of metoclopramide may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine.

Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

Hypotension, bradycardia, shock, and other abnormalities or cardiac conduction occurred most frequently with IV formulations.
Cardiac arrest occurred shortly after IV administration, and may have been subsequent to bradycardia.
Sinus arrest and transient facial/upper body flushing occurred, particularly with IV administration. Flushing typically occurred without alterations in vital signs following high dose IVs.
Edema/fluid retention may be secondary to a transient increase in aldosterone levels.
Acute hypertension has occurred in patients with pheochromocytoma.
Hypertension has occurred in patients with/without pheochromocytoma.
Common (1% to 10%): Hypotension
Uncommon (0.1% to 1%): Bradycardia

Frequency not reported: Breast enlargement, impotence, priapism, sexual dysfunction, urinary frequency, urinary incontinence
