Administration Guidelines for Metoclopramide in Felines

Metoclopramide Hydrochloride 10 mg Tablets are prescribed to cats to manage vomiting, nausea, delayed gastric emptying, and gastrointestinal stasis. Proper dosing and administration are crucial for ensuring the medication is both effective and safe.

General Dosing Guidelines

The standard oral dosage for cats is typically:

0.2–0.5 mg per kg of body weight, given every 8 hours (three times a day), or as prescribed by a veterinarian.

Dosage (By Weight)

Note: Tablets may need to be split or compounded into smaller doses by a veterinary pharmacist for accuracy.

Duration of Use

• Short-term treatment: Typically 3 to 5 days for acute vomiting or nausea.
• Chronic or supportive use: May be extended under strict veterinary monitoring, especially for conditions like gastroparesis or chemotherapy-induced nausea.

Administration Tips

• Give with or without food: May be administered on an empty stomach or with a small amount of food if preferred.
• If vomiting persists within 30 minutes of dosing, re-dosing may be considered under veterinary advice.
• For cats that resist pills, compounded liquid formulations may be easier to administer and allow for more precise dosing.

Adjustments & Monitoring

• Elderly or debilitated cats may require more cautious administration and observation.
• Monitor for any side effects like restlessness, sedation, or tremors. Adjust or discontinue under vet supervision.

Veterinary Advice

Always administer exactly as prescribed by your veterinarian. Do not exceed the recommended dose without consulting a professional, as higher doses may increase the risk of central nervous system side effects.

Pro Tip for Pet Owners

If splitting tablets is difficult or causes dosage inconsistency, ask your vet for a compounded formulation (liquid or chewable), especially for smaller cats or those on multiple medications.

Safety Guidelines and Potential Side Effect

When used responsibly under veterinary supervision, Metoclopramide Hydrochloride 10 mg Tablets are generally safe and effective for treating gastrointestinal disturbances in cats. However, like any medication, there are important precautions and potential side effects to be aware of.

Safety Profile

• Veterinary Approved: Widely used in small animal practice for over 40 years.
• Non-sedating in most cats when used at standard doses.
• Short-acting with a relatively quick clearance, minimizing the risk of long-term buildup.

Precautions

Before starting treatment, your veterinarian will consider the following:

• Do not use in cats with suspected GI obstruction, perforation, or hemorrhage, as Metoclopramide increases gastrointestinal motility.
• Use cautiously in cats with:
  • Kidney or liver disease (dose adjustment may be necessary).
  • Seizure disorders, due to a rare risk of neurologic side effects.
• Avoid concurrent use with phenothiazine-based drugs (e.g., acepromazine), as they may increase the risk of central nervous system reactions.
• Monitor cats with heart conditions closely if used long-term.

Possible Side Effects

• Mild drowsiness or sedation
• Occasional restlessness or hyperactivity
• Rare muscle tremors or twitching
• Possible diarrhea or constipation
• Rare vocalization or behavior changes
• Very rare seizures in sensitive cats

Contraindications & Drug Interactions

While Metoclopramide Hydrochloride 10 mg Tablets are generally safe when used under veterinary supervision, there are specific conditions and drug combinations where use should be avoided or carefully monitored. Understanding these is crucial to preventing complications and ensuring the medication’s effectiveness.

Contraindications

1. Gastrointestinal Obstruction or Perforation
   • Stimulating GI motility in these cases can worsen the condition and lead to rupture or hemorrhage.
2. Epilepsy or Seizure Disorders
   • May lower seizure threshold, increasing the risk of convulsions.
3. GI Bleeding or Intestinal Hemorrhage
   • Increases motility and may lead to further complications.
