Reglan tablets are indicated for the:
Limitations of Use:
Reglan tablets are not recommended for use in pediatric patients due to the risk of developing tardive dyskinesia (TD) and other extrapyramidal symptoms as well as the risk of methemoglobinemia in neonates [see Use in Specific Populations (8.4)].
Avoid treatment with Reglan for longer than 12 weeks because of the increased risk of developing TD with longer-term use [see Dosage and Administration (2.2, 2.3), Warnings and Precautions (5.1)].
Reglan tablets may be administered continuously or intermittently in patients with symptomatic gastroesophageal reflux who fail to respond to conventional therapy.
The recommended adult dosage of Reglan is 10 to 15 mg four times daily for 4 to 12 weeks. The treatment duration is determined by endoscopic response. Administer the dosage thirty minutes before each meal and at bedtime. The maximum recommended daily dosage is 60 mg.
Table 1 displays the recommended daily dosage and maximum daily dosage for adults and dosage adjustments for patients with moderate or severe hepatic impairment (Child-Pugh B or C), in patients with creatinine clearance less than 60 mL/minute, in cytochrome P450 2D6 (CYP2D6) poor metabolizers, and with concomitant use with strong CYP2D6 inhibitors.
If symptoms only occur intermittently or at specific times of the day, administer Reglan in single dose up to 20 mg prior to the provoking situation. Consider dosage reductions for the populations and situations in Table 1.
Table 1. Recommended Reglan Tablet Dosage in Patients with Gastroesophageal Reflux:
| Recommended Dosage | Maximum Recommended Daily Dosage | |
|---|---|---|
| Adult patients | 10 to 15 mg four times daily (thirty minutes before each meal and at bedtime) | 60 mg |
| Mild hepatic impairment (Child-Pugh A) | ||
| Elderly patients [see Use in Specific Populations (8.5)] | 5 mg1 four times daily (thirty minutes before each meal and at bedtime) | |
| Moderate or severe hepatic impairment (Child-Pugh B or C) [see Use in Specific Populations (8.7)] | 5 mg four times daily (thirty minutes before each meal and at bedtime), or 10 mg taken three times daily | 30 mg |
| CYP2D6 poor metabolizers [see Use in Specific Populations (8.9)] | ||
| Concomitant use with strong CYP2D6 inhibitors (e.g., quinidine, bupropion, fluoxetine, and paroxetine) [see Drug Interactions (7.1)] | ||
| Moderate or severe renal impairment (creatinine clearance less than or equal to 60 mL/minute) [see Use in Specific Populations (8.6)] | ||
| Patients with End-Stage Renal Disease (ESRD) including those treated with hemodialysis and continuous ambulatory peritoneal dialysis [see Use in Specific Populations (8.6)] | 5 mg four times daily (thirty minutes before each meal and at bedtime) or 10 mg twice daily | 20 mg |
1 Elderly patients may be more sensitive to the therapeutic or adverse effects of Reglan; therefore, consider a lower starting dosage of 5 mg four times daily with titration to the recommended adult dosage of 10 to 15 mg four times daily based upon response and tolerability.
The recommended adult dosage for the treatment of acute and recurrent diabetic gastroparesis is 10 mg four times daily for 2 to 8 weeks, depending on symptomatic response. Avoid Reglan treatment for greater than 12 weeks [see Warnings and Precautions (5.1)]. Administer the dosage thirty minutes before each meal and at bedtime. The maximum recommended daily dosage is 40 mg.
Table 2 displays the recommended daily dosage and maximum daily dosage for adults and dosage adjustments for patients with moderate or severe hepatic impairment (Child-Pugh B or C), in patients with creatinine clearance less than 60 mL/minute, in cytochrome P450 2D6 (CYP2D6) poor metabolizers, and with concomitant use with strong CYP2D6 inhibitors.
If patients with diabetic gastroparesis have severe nausea or vomiting and are unable to take oral Reglan tablets, consider starting therapy with metoclopramide injection given intramuscularly or intravenously for up to 10 days (see the prescribing information for metoclopramide injection). After patients are able to take oral therapy, switch to Reglan tablets.
Table 2. Recommended Reglan Tablet Dosage in Patients with Acute and Recurrent Diabetic Gastroparesis:
| Recommended Dosage | Maximum Recommended Daily Dosage | |
|---|---|---|
| Adult Patients | 10 mg four times daily (30 minutes before each meal and at bedtime) | 40 mg |
| Mild hepatic impairment (Child-Pugh A) | ||
| Elderly patients [see Use in Specific Populations (8.5)] | 5 mg1 four times daily (30 minutes before each meal and at bedtime) | |
| Moderate or severe hepatic impairment (Child-Pugh B or C) [see Use in Specific Populations (8.7)] | 5 mg four times daily (30 minutes before each meal and at bedtime) | 20 mg |
| CYP2D6 poor metabolizers [see Use in Specific Populations (8.9)] | ||
| Concomitant use with strong CYP2D6 inhibitors (e.g., quinidine). Avoid use with bupropion, fluoxetine, and paroxetine [see Drug Interactions (7.1)] | ||
| Moderate or severe renal impairment (creatinine clearance less than 60 mL/minute) [see Use in Specific Populations (8.6)] | ||
| Patients with End-Stage Renal Disease (ESRD) including those treated with hemodialysis and continuous ambulatory peritoneal dialysis [see Use in Specific Populations (8.6)] | 5 mg twice daily | 10 mg |
1 Elderly patients may be more sensitive to the therapeutic or adverse effects of Reglan; therefore, consider a lower dosage of 5 mg four times daily with titration to the recommended adult dosage of 10 mg four times daily based upon response and tolerability.
Manifestations of metoclopramide overdosage included drowsiness, disorientation, extrapyramidal reactions, other adverse reactions associated with metoclopramide use (including, e.g., methemoglobinemia), and sometimes death. Neuroleptic malignant syndrome (NMS) has been reported in association with metoclopramide overdose and concomitant treatment with another drug associated with NMS [see Warnings and Precautions (5.1, 5.2, 5.3)].
There are no specific antidotes for Reglan overdosage. If over-exposure occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.
Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency, which may be fatal.
Hemodialysis and continuous ambulatory peritoneal dialysis do not remove significant amounts of metoclopramide.
Dispense tablets in tight, light-resistant container. Store tablets at controlled room temperature between 20°C and 25°C (68°F and 77°F).
