Clomipramine for Scorpion: Uses, Dosing & Side Effects

This information is for educational purposes only. Never give your pet any medication without your veterinarian's guidance. Dosing, frequency, and safety depend on your pet's specific health profile.

Clomipramine is a tricyclic antidepressant that changes how certain brain chemicals, especially serotonin, are handled. In veterinary medicine, the FDA-approved canine use is separation anxiety in dogs older than 6 months, and it is meant to be used with behavior modification, not as a stand-alone fix.

You may also hear the brand name Clomicalm. Your vet may prescribe clomipramine off-label in some pets for compulsive or anxiety-related behaviors, but the strongest labeled evidence is in dogs with separation anxiety. It is not a sedative, so many pets do not look immediately calmer after the first dose.

One important note for this page: despite the title wording, clomipramine is a medication used in veterinary patients such as dogs and sometimes cats. It is not a standard medication for scorpions, and any use in an exotic species would require direct guidance from a veterinarian with appropriate species expertise.

In dogs, clomipramine is used as part of a comprehensive behavioral management program for separation anxiety. That usually means medication is paired with home changes and training steps such as desensitization, predictable departures, and avoiding punishment-based responses.

Your vet may also consider clomipramine for some anxiety disorders, phobias, or compulsive behaviors when the history and exam support that plan. In cats, veterinary references describe off-label use for some compulsive behaviors or urine spraying, but cats can be more sensitive to side effects.

This medication is not usually chosen as an as-needed drug for a single stressful event. It often takes several weeks to judge benefit, so pet parents should expect follow-up visits and dose adjustments rather than instant results.

Clomipramine dosing must come from your vet, because the right dose depends on species, body weight, medical history, and the reason it is being used. For the FDA-approved canine label, the recommended total daily dose is 2 to 4 mg/kg/day by mouth, given once daily or divided twice daily based on response and tolerance.

The labeled dog tablets are available in 5 mg, 20 mg, 40 mg, and 80 mg strengths. Your vet may start on the lower end of the range or split the daily dose to reduce stomach upset or sleepiness early in treatment. Because behavior medications often need time, your vet may recommend a trial of several weeks before deciding whether the plan is helping enough.

Do not change the dose, stop suddenly, or combine clomipramine with other behavior medications unless your vet tells you to. If a dose is missed, contact your veterinary team for instructions. In many cases, they will advise either giving it when remembered or skipping it if the next dose is close, but the safest plan depends on your pet's schedule and other medications.

Common side effects in dogs include vomiting, lethargy, diarrhea, increased thirst, and decreased appetite. In clinical field studies, vomiting and lethargy were among the most commonly reported reactions. Some pets also develop dry mouth, constipation, tremors, or behavior changes.

More serious problems need prompt veterinary attention. Call your vet right away if you notice seizures, collapse, confusion, fever, fast or irregular heartbeat, marked agitation, severe weakness, or trouble urinating. Liver-related problems have also been reported, especially in pets with pre-existing liver disease.

Cats may be more sensitive to adverse effects than dogs. Signs such as drooling, unsteadiness, or a poor haircoat have been reported in cats. If your pet seems dramatically worse after starting the medication, or if there is any chance of an overdose, see your vet immediately.

Clomipramine has several important drug interactions, so your vet needs a full list of all prescriptions, preventives, supplements, and herbal products your pet receives. The most important labeled warning is to avoid monoamine oxidase inhibitors (MAOIs) at the same time or within 14 days before or after clomipramine. In veterinary medicine, examples include selegiline and amitraz products.

Other medications that can increase risk include drugs that lower the seizure threshold, other serotonergic medications such as some antidepressants, and medicines that can add to sedation or affect heart rhythm. Because clomipramine can also influence some lab values, your vet may want baseline or follow-up testing in pets with liver, kidney, thyroid, heart, or seizure concerns.

Clomipramine is also contraindicated in dogs with a history of seizures, in dogs with known hypersensitivity to tricyclic antidepressants, and it should not be used in breeding male dogs. Always ask before combining it with flea/tick products, behavior medications, sleep aids, or over-the-counter human medicines.
