Clomipramine for Dogs

Clomipramine (brand: Clomicalm) is a prescription anxiety/behavior medication for dogs. It’s in the tricyclic antidepressant (TCA) class. Top uses: FDA‑approved to help treat canine separation anxiety as part of a behavior plan. Veterinarians may also prescribe it for other anxiety-related issues or certain repetitive/compulsive behaviors (e.g., excessive licking or tail chasing). Your veterinarian can discuss expected benefits, timeline, and what to monitor at home. Safety note for reception: This is Rx‑only for dogs. If an owner reports the dog swallowed extra doses or is showing severe signs like seizures, collapse, or extreme lethargy, escalate to the veterinarian or direct them to an emergency clinic/poison control immediately.

Common owner FAQs (use these short Q&As in plain language): - What is clomipramine for? It’s a prescription medicine for dogs with separation anxiety and is used together with a behavior/training plan. It’s approved for dogs over 6 months of age. Improvement is not instant—most dogs need several weeks before you notice clear changes. Your veterinarian can discuss expected timelines and any plan adjustments. - Will it make my dog sleepy? Some dogs seem a bit tired at first. Mild stomach upset (vomiting/diarrhea) or lower appetite can happen. If signs are severe, last more than a day, or your dog seems very agitated, call us so the veterinarian can advise. If your dog collapses, has seizures, a very fast/irregular heartbeat, or a high fever, seek emergency care now. - Can I give it with food? Yes. It can be given with or without food; if it upsets the stomach, giving with a small amount of food may help. Ask our veterinarian before making any medication changes. - What if I miss a dose? If you remember later, give the dose unless it’s close to the next scheduled time—then skip the missed dose and resume the regular schedule. Don’t double up. If multiple doses are missed, our veterinarian can advise how to get back on track. - Is it safe with other meds or flea/tick collars? Some combinations are unsafe. Do not use clomipramine with monoamine oxidase inhibitors (for example, selegiline/Anipryl) or certain older tick collars that contain amitraz, and a 14‑day separation from those products is recommended. Always tell us about all medicines and supplements your dog gets—your veterinarian will confirm what’s safe.

What owners most often report when starting clomipramine: mild sleepiness/low energy and stomach upset (vomiting, soft stool/diarrhea, or a temporary drop in appetite). Increased thirst/dry mouth may be noticed, and some dogs may urinate more often. These effects were among the most common events in clinical trials for Clomicalm (vomiting, lethargy, diarrhea) and are also described in client handouts; they are typically mild. Your veterinarian can discuss what’s expected for this individual dog. ([drugs.com](https://www.drugs.com/vet/clomicalm-clomipramine-hydrochloride.html?utm_source=openai)) Call the clinic the same day if: vomiting happens more than once; diarrhea or poor appetite lasts beyond 24 hours; the dog seems unusually listless or confused; you notice marked behavior changes (new agitation or aggression); or thirst/urination increases noticeably. Seek urgent/emergency care now for seizures, collapse/fainting, very fast or very slow/irregular heartbeat, high body temperature (hot to the touch, excessive panting), tremors, or inability to urinate—these can be serious reactions reported with tricyclic antidepressants and on the product label. Do not change how the medication is given unless the veterinarian directs you; your veterinarian can advise on next steps. ([drugs.com](https://www.drugs.com/pro/clomicalm.html?utm_source=openai))

Available forms and how to give: Clomipramine for dogs is dispensed as veterinary tablets (brand Clomicalm; generics also exist). Clomicalm tablets come in several strengths; current U.S. labeling lists 5, 20, and 80 mg, and FDA‑approved generics are available in 5, 20, 40, and 80 mg. Give at the same time each day. It’s fine to give with a small amount of food—this can reduce stomach upset and the drug is absorbed well when given with food. Do not crush or open tablets unless the veterinarian specifically okays it; many medicines are very bitter when crushed and pets may refuse the dose or only eat part of it. Keep out of reach of children and wash hands after handling. Your veterinarian can discuss the best way to give it for your dog’s plan. [No dosing amounts to be given by front desk.] Troubleshooting a dog that won’t take it: Try a pill pocket or a tiny “treat sandwich” (a few empty treats first, then the hidden tablet, then another treat). You can also place the tablet at the back of the tongue and offer a small water or food “chaser.” Avoid mixing a crushed pill into a full meal—bitter taste can lead to partial dosing. If tablets are a struggle, your veterinarian can authorize a compounding pharmacy to make a flavored liquid, capsule, or chew to improve acceptance and will advise which form is appropriate. If vomiting occurs: Giving with a small amount of food often helps. If the dog vomits soon after dosing, check for an intact tablet in the vomit and call the clinic before redosing. Escalate same day if vomiting happens more than once, if the dog can’t keep water down, if you see blood, or if the pet is very lethargic—these warrant urgent veterinary attention. If you suspect a double dose or other ingestion, contact us and/or ASPCA Animal Poison Control. Your veterinarian can guide any changes to how it’s given.

Clomipramine (brand: Clomicalm) is a prescription-only medication for dogs. All refills require a valid prescription from our veterinarian and an active veterinarian–client–patient relationship (VCPR). Follow clinic policy for recheck timing; your veterinarian will advise when a progress exam or lab monitoring is due before approving refills. Standard turnaround for non-urgent refills is 1–2 business days; same-day approval is not guaranteed. When taking a refill request, collect: pet and owner name, medication name as shown on the label, tablet size on the label, directions on the label, how many doses remain, preferred pharmacy (in-house or outside), and the pharmacy’s phone/fax or e-prescribe details. For online pharmacies, we can send the prescription directly or provide a written script; use only pharmacies that require veterinary authorization and are appropriately licensed. If the caller reports severe vomiting/diarrhea, marked sedation or agitation, tremors, seizures, fainting, or fast/irregular heartbeat, pause the refill and connect them with a veterinarian immediately; if collapse, seizures, or breathing trouble are occurring now, direct them to the nearest emergency clinic. Your veterinarian can discuss refill quantities, recheck intervals, and any needed monitoring or behavior follow-up.

Escalate to a veterinarian or technician immediately for any of the following while a dog is taking clomipramine (Clomicalm): seizures; collapse or fainting; trouble breathing; very fast or irregular heartbeat; high fever; severe agitation, shaking/tremors, muscle stiffness, or sudden confusion; repeated vomiting or diarrhea with marked lethargy; or unusual bleeding/bruising. These can represent serious adverse reactions, including rare neurologic or cardiac effects. Your veterinarian can discuss which side effects are expected versus dangerous and what monitoring is appropriate. Suspected overdose or drug interactions are emergencies. Red flags of overdose or serotonin toxicity (more likely if combined with other behavior meds such as SSRIs, MAOIs like selegiline, trazodone, or tramadol) include tremors, incoordination/wobbly gait, dilated pupils, vocalization, rapid heart rate, high body temperature, and seizures. If a pet may have chewed into the bottle or received extra doses, escalate immediately. Treat facial swelling, hives, sudden vomiting/diarrhea, or any breathing change as a potential severe allergic reaction—get a veterinarian/tech now. If the clinic cannot be reached and overdose is suspected, direct the caller to the nearest emergency hospital; poison control resources are also available (ASPCA APCC 888-426-4435; Pet Poison Helpline 855-764-7661).

Clomipramine (Clomicalm) can interact with several other medicines. The most important red flag is any monoamine oxidase inhibitor (MAOI) such as selegiline (Anipryl) or amitraz tick products (e.g., Preventic/mitaban dips). The product label says clomipramine must not be used together with MAOIs and requires a 14‑day separation, so alert a veterinarian immediately if these are mentioned. Medicines that affect blood pressure/heart rhythm (sympathomimetics) or strongly increase sedation also need veterinarian review before combining with clomipramine. Your veterinarian can discuss if a washout or alternative plan is needed before any changes are made. Common meds to ask about and flag for review: trazodone (situational anxiety), fluoxetine/other antidepressants, tramadol (pain), phenylpropanolamine/Proin (urinary incontinence), and recent or current use of selegiline or amitraz collars/dips. Also flag certain antifungals (ketoconazole/itraconazole), some antibiotics (e.g., macrolides), cimetidine, anesthetics/sedatives, and phenobarbital or phenytoin (these can change clomipramine levels or increase side effects). If the pet is scheduled for sedation/anesthesia, make sure the medical team knows the dog is on clomipramine. Do not advise starting, stopping, or changing any medication; the veterinarian will decide the plan. OTC items owners often give that warrant a check-in: antihistamines like diphenhydramine (Benadryl) due to added drowsiness; cough/cold syrups with dextromethorphan (can contribute to serotonin-related side effects); and serotonin-related supplements like St. John’s wort or 5‑HTP. If an owner reports restlessness, agitation, tremors/shivering, vomiting/diarrhea, fever, very fast heart rate, severe lethargy, or collapse after combining medicines or giving an OTC product, escalate immediately—this may be an emergency. Your veterinarian can advise on safe alternatives and whether any monitoring or washout is needed.

Storage: Keep Clomicalm (clomipramine) tablets in a dry place at controlled room temperature (59–77°F / 15–25°C). Store in the original, tightly closed manufacturer container. These tablets are formulated with meat components (palatable), so keep the bottle locked away and out of sight/reach of pets and children—do not leave it on counters, in bags, or in easily opened drawers. Your veterinarian can advise on any clinic-specific storage instructions at pickup. Shelf life after opening: The U.S. label does not list a special “discard after opening” period for the tablets. Use the product until the printed expiration date when stored properly in the original closed container. If your clinic repackages tablets into a different vial, follow the clinic label’s beyond‑use date and ask the veterinarian if there are questions. Disposal: Prefer a drug take‑back program. If no take‑back is available and the medicine is not on the FDA flush list, mix tablets (do not crush) with something unappealing like used coffee grounds or cat litter, seal in a bag or container, and place in household trash. Remove personal information from empty bottles. Do not flush unless the drug is on the FDA flush list. If a child or another pet accidentally swallows tablets, or a dog eats more than prescribed, this is urgent—direct the owner to contact Poison Control/seek human medical care or go to an emergency veterinary hospital immediately. Your veterinarian can discuss next steps after urgent care is arranged.

Before or soon after starting clomipramine, the veterinarian may order baseline tests—especially liver values—and sometimes an electrocardiogram (ECG). Because clomipramine and other tricyclic antidepressants can take about 1–4 weeks to show benefit, plan a progress check within that window so the doctor can review behavior changes and any side effects; the exact timing is set by the veterinarian. Clomipramine’s full effect may take a few weeks, with gradual improvements sometimes noted after a few days. There is no single universal lab schedule for dogs on clomipramine. The product label advises periodic rechecks of bloodwork during treatment, and the doctor may request liver enzyme monitoring during longer-term use or when other medications are given. Let the team know if outside labs are planned, as clomipramine can affect some test results (thyroid and glucose). The label also notes that safety beyond 12 weeks has not been fully evaluated; your veterinarian will determine duration and follow-up needs. At home, owners should watch for common issues like vomiting, diarrhea, tiredness, appetite changes, or trouble urinating. Escalate immediately for seizures, collapse/fainting, very fast or irregular heartbeat, fever, or abnormal bleeding—these require emergency care now. For any medication questions or to individualize monitoring, your veterinarian can discuss the specific plan with the owner.

Clomipramine (brand: Clomicalm) is a prescription behavior medication for dogs that helps with separation anxiety and is meant to be used together with a behavior plan from the veterinarian. It is not recommended for male breeding dogs and must not be used with monoamine oxidase inhibitors (for example, selegiline/Anipryl or amitraz collars) or in dogs with a history of seizures—these checks should be confirmed by the care team. Commonly reported effects include vomiting, sleepiness, diarrhea, and decreased appetite; your veterinarian can discuss what is expected versus concerning for the individual pet. Front-desk triage: if a caller reports collapse, a seizure, very fast or irregular heartbeat, severe vomiting/diarrhea, extreme lethargy, or an accidental overdose (extra pills chewed or swallowed), instruct them to seek emergency care immediately and notify the medical team. For non-urgent questions (missed dose, mild stomach upset, timing with food, interactions with other meds, training guidance), schedule a same-day callback or appointment with the veterinarian; do not give dosing or start/stop advice. Phrases to avoid: “It’s safe to start/stop,” “Give an extra dose,” “It works for aggression,” or “It’s fine with all meds/collars.” Safer alternatives: “Because this drug can interact with certain medications and flea/tick collars and isn’t for some dogs, the veterinarian will advise,” and “Please don’t change how you’re giving it until the doctor confirms the plan.”
