Mirtazapine Tablets, 7.5mg

Prescription Appetite Stimulant and Antiemetic Tablets for Dogs and Cats

Product Description

Mirtazapine Tablets 7.5 mg is a prescription antidepressant used off-label in dogs and cats primarily as an appetite stimulant and anti-nausea agent. It works by blocking chemical signals in the brain that trigger nausea and appetite suppression, helping pets with chronic illness, kidney disease, or gastrointestinal conditions maintain adequate food intake and body weight. It may also be used occasionally to support behavioural management in cats.

Benefits

• Appetite Stimulation: Encourages dogs and cats with anorexia or illness-related reluctance to eat to start taking in food again.
• Nausea and Vomiting Relief: Interrupts the gut-to-brain nausea signal, making it a useful option for pets dealing with frequent vomiting or treatment-related queasiness.
• Chemotherapy Support: Helps offset appetite loss and nausea in pets going through cancer treatment, keeping nutritional intake on track during therapy.
• Kidney Disease: Widely used in cats with chronic renal failure to nudge appetite and ease the nausea that comes with declining kidney function.
• Weight Loss Prevention: Helps reduce undesired weight loss in cats and dogs with dental, gastrointestinal, or other systemic diseases affecting their appetite.

Additional Information

Precautions

• Avoid After MAOI Use: Do not give mirtazapine to pets that have received a monoamine oxidase inhibitor (MAOI) within the previous 14 days.
• Liver or Kidney Disease: Pets with hepatic or renal impairment may need a lower dose, as the medication can stay active longer in their system.
• Cardiac Disease: Use with care in pets with known heart disease, as mirtazapine can affect both blood pressure and heart rate.
• Pregnancy: The safety of mirtazapine in pregnant or nursing animals is not yet established, so only use it when the benefits clearly outweigh the risks.
• Blood Disease Monitoring: Pets with a history of leukemia, low platelets, or blood disorders can still receive mirtazapine but will require regular blood work monitoring throughout.
• Drug Interactions: Inform your veterinarian of all medications your pet is currently taking, particularly SSRIs, tricyclic antidepressants, tramadol, or diazepam.

Possible Side Effects

• Drowsiness: Mild sedation is the most commonly reported side effect in both dogs and cats taking mirtazapine tablets.
• Vocalization in Cats: Cats may vocalise more than usual after receiving mirtazapine; contact your vet if this is excessive or distressing.
• Muscle Tremors: Trembling or shaking can occur and may be a sign of serotonin-related sensitivity; report to your veterinarian promptly if observed.
• Elevated Heart Rate: An increase in heart rate has been documented and is particularly relevant to monitor in pets with pre-existing cardiac conditions.
• Incoordination: Some pets may appear unsteady on their feet after dosing, which should be reported to the veterinarian if it persists or worsens.
• Serotonin Syndrome (Rare): Restlessness, agitation, high fever, and rapid breathing are warning signs of this serious but uncommon complication requiring immediate veterinary attention.

Ans: Mirtazapine is a prescription medication used off-label in cats and dogs primarily as an appetite stimulant and anti-nausea agent.

Q2: How long does mirtazapine take to work in cats and dogs?

Ans: Mirtazapine typically begins to take effect within one to two days of starting treatment, with noticeable improvement in appetite and reduction in nausea expected to follow. Effects last approximately 24 hours, though this may be prolonged in pets with liver or kidney disease.

Q4: Can mirtazapine be used in cats with chronic kidney disease?

Q5: Does mirtazapine require regular veterinary monitoring in pets?

Ans: Yes, particularly in pets with a history of blood disorders, liver, or kidney conditions.
