A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Mirataz is a prescription appetite stimulation medication for cats that is used to help cats gain needed weight when addressing unintended feline weight loss. It is applied as a topical ointment and the active ingredient in the medication – Mirtazapine – is a presynaptic α-2 receptor antagonist medication that stimulates serotonin and histamine receptors to give the cat more of an appetite. Then with increased consumption of food comes the required weight gain needed for the animal to be at a healthier body weight. You can buy Mirataz from Canpharm.
Unintended Feline Weight Loss is a condition where a cat is in poorer health and suffering from malnutrition because of having an insufficient appetite. Their lack of a desire to eat normally is not due to any type of aversion to food or anything else of the sort, however, and instead is the result of an adjoining medical condition. These conditions include hyperthyroidism, chronic kidney disease, inflammatory bowel disease, pancreatitis, neoplasia, or liver failure.

What is Mirataz, and what is it used for?
Mirataz is a prescription transdermal ointment containing mirtazapine, which is used in cats to stimulate appetite and help manage weight loss. Mirtazapine, the active ingredient, has effects on neurotransmitters that can increase appetite and promote weight gain in cats suffering from underlying illnesses that cause a lack of appetite, such as kidney disease or cancer.
How does Mirataz work?
Mirataz (mirtazapine) works by influencing serotonin and norepinephrine levels in the brain, which are linked to appetite regulation. Its transdermal formulation allows it to be absorbed through the cat’s skin, offering a non-oral route to help stimulate eating behavior and assist with weight maintenance.
How is Mirataz applied?
Mirataz is typically applied once daily to the inner surface of the cat's ear (usually the pinna). A measured dose is administered by applying the ointment directly from the tube or with a gloved finger. Hands or gloves should be thoroughly washed after application to avoid accidental exposure.
How long does it take for Mirataz to start working?
Most cats begin to show increased appetite within 1 to 2 days of starting Mirataz treatment. However, the full effects may vary depending on the cat's individual response and the severity of its appetite loss.
What are the common side effects of Mirataz?
Common side effects of Mirataz include increased vocalization, mild sedation, or changes in behavior. Other side effects, although less common, can include vomiting or elevated liver enzymes. If any adverse reactions are observed, it’s important to contact a veterinarian.
Are there any cats that should not use Mirataz?
Mirataz should not be used in cats with a known hypersensitivity to mirtazapine or those with severe liver or kidney conditions without veterinary guidance. Pregnant or lactating cats should also not be given Mirataz without a veterinarian’s advice.
Can Mirataz interact with other medications?
Yes, Mirataz can interact with certain medications, including those that affect serotonin levels (like SSRIs or monoamine oxidase inhibitors). It’s important to inform the veterinarian of any other medications or supplements the cat is currently taking.
How should Mirataz be stored?
Store Mirataz at room temperature (68-77°F or 20-25°C) and keep it away from light and moisture. Ensure the tube is securely closed and kept out of reach of children and pets when not in use.
What should I do if I miss a dose?
If a dose of Mirataz is missed, apply it as soon as possible. If it’s close to the time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not apply extra to make up for a missed dose.
Is Mirataz safe for humans?
No, Mirataz is formulated specifically for feline use. Human exposure should be avoided, especially by children and pregnant individuals, as mirtazapine may be absorbed through human skin. In case of accidental human contact, the area should be washed immediately with soap and water, and medical advice should be sought if necessary.
