Lorazepam (brand name Ativan) is a prescription anti‑anxiety and calming medication in the benzodiazepine class. In dogs, it’s used for short‑term fear/anxiety situations (for example, thunderstorms, fireworks, travel, or vet visits). Veterinarians may also use lorazepam in‑clinic to help stop active seizures. It is Rx‑only and a U.S. Schedule IV controlled substance.
This drug is commonly used extra‑label in veterinary medicine. Your veterinarian can discuss if it’s appropriate for your dog and what to expect. If a dog becomes extremely drowsy, unsteady, unusually agitated, vomits repeatedly, or has trouble breathing after a dose, contact the clinic immediately or seek emergency care.
Front desk script: Lorazepam—brand name Ativan—is a benzodiazepine used to help calm dogs during short‑term anxiety, like storms or vet visits. Our vets may also use it in the hospital to help stop seizures. It’s prescription‑only and a Schedule IV controlled medication, so we need a current prescription and secure handling. Your veterinarian can advise if this is right for your dog and how it should be used. If your dog seems extremely sleepy, wobbly, unusually agitated, or has trouble breathing after a dose, contact us right away or go to the nearest emergency clinic.
Common owner FAQs (plain language)
Q: What is lorazepam and why was it prescribed? A: Lorazepam (brand: Ativan) is a benzodiazepine used by veterinarians to help with short‑term anxiety in dogs and may also be used in hospital settings for seizures. It’s an “off‑label” use in pets and must be used only under your veterinarian’s direction.
Q: How fast will it work and how might my dog act? A: It often starts working within about an hour. Many dogs get sleepy or a bit wobbly; a small number can act the opposite—restless, agitated, or unusually vocal. Supervise your dog the first time it’s given and call us if you’re worried.
Q: Can it be given with food? What if I miss a dose? A: It can be given with or without food; giving with a small meal or treat may help if the stomach seems upset. If a dose is missed, do not double up—call us for instructions. Do not stop or change how you give it unless your veterinarian tells you to.
Q: Is it safe with my dog’s other meds or health issues? A: Your veterinarian must review all medications and supplements first. Lorazepam can interact with other drugs that cause drowsiness (sedatives, pain meds), some antidepressants (like fluoxetine or tricyclics), antacids, theophylline/aminophylline, and others. It shouldn’t be used in pets with severe breathing problems or significant liver disease; use caution with glaucoma, kidney disease, and in seniors.
Q: What side effects are urgent? A: Call the clinic the same day for severe wobbliness, persistent vomiting, or marked agitation. Go to emergency care now if your dog is hard to wake, collapses, has trouble breathing, or you suspect an overdose or pill‑raid; you can also call Pet Poison Helpline (855‑764‑7661) or ASPCA Animal Poison Control (888‑426‑4435). Yellow gums/eyes (possible jaundice) also needs prompt veterinary attention. Store lorazepam locked up—it's a Schedule IV controlled medicine; never share human medication with pets. Your veterinarian can discuss what to expect for your dog and any monitoring needed.
Front desk script: Lorazepam, also called Ativan, was prescribed to help with your dog’s short‑term anxiety. It can make dogs sleepy or wobbly, but a few dogs may act more restless—please supervise the first use and call us if you’re concerned. Don’t change the dose, timing, or stop the medication without speaking with our veterinarian. If your dog is extremely drowsy, hard to wake, has trouble breathing, collapses, or may have eaten extra pills, go to the ER immediately and you can also call Pet Poison Helpline at 855‑764‑7661 or ASPCA Animal Poison Control at 888‑426‑4435.
What owners most often report after a dose of lorazepam: their dog seems very sleepy, wobbly/unstable on their feet, a bit weak, or drools more than usual. These effects are expected with benzodiazepines and are typically short‑lived; for most dogs they wear off within about a day, though effects can last longer in pets with liver or kidney disease. Ask the owner to keep the dog in a safe, quiet area and use ramps or gates to prevent stairs/falls.
Less common, some dogs show the opposite reaction ("paradoxical"): restlessness, pacing, louder vocalizing, increased anxiety, or unusual/aggressive behavior. If an owner reports these changes, separate the dog from children/other pets for safety and schedule a same‑day veterinarian call-back. The veterinarian can discuss whether these reactions are acceptable or if the plan should be adjusted.
Escalate immediately if an owner reports any of the following: the dog is very hard to wake or won’t respond, can’t stand, collapses, has trouble breathing, has repeated vomiting, has pale/blue gums, or you see yellow gums/eyes. Also escalate if an extra dose may have been given, the dog chewed into the bottle, or another sedative was given as well—these are emergencies; direct the owner to the nearest emergency clinic or animal poison control while you alert the medical team.
Front desk script: Thanks for calling—some sleepiness and wobbliness can be normal after lorazepam and often wear off within a day. If your dog seems unusually agitated, vocal, or aggressive, please keep them separated from kids and other pets and I’ll have our veterinarian call you today to advise next steps. If your dog is very hard to wake, can’t stand, is having trouble breathing, or may have gotten an extra dose, please go to the nearest emergency vet now and call us on the way. Your veterinarian can discuss what to expect and whether any changes are needed.
Forms and giving: Lorazepam for dogs is dispensed as human‑labeled tablets or an oral liquid. It can be given with or without food; if it upsets the stomach when given on an empty stomach, future doses can be given with a small snack. Tablets can dissolve quickly in the mouth—placing the pill toward the back of the cheek and then offering a treat may help. Measure liquids carefully. Do not change how you give it (crushing, splitting, changing timing) without veterinary guidance.
Pilling tricks: Hide tablets in a tiny bite of soft, moldable food (pill pockets, cheese, peanut butter without xylitol) and follow with a “chaser” treat so your dog swallows before tasting the pill. Offer one or two plain treats, then the medicated one, then another plain treat to encourage quick swallowing. A pill‑giving device or a compounded flavored liquid/chew may be options if pilling is a struggle—your veterinarian can discuss pros/cons. Avoid any product sweetened with xylitol (some human liquids and sugar‑free foods), which is toxic to dogs.
Troubleshooting and when to call: If your dog spits out the dose, try again with a fresh treat. If your dog vomits after a dose or can’t keep medicine down, call the clinic before giving more. Seek emergency care now for extreme sleepiness or unresponsiveness, severe wobbliness, trouble breathing, collapse, or severe agitation. For ongoing problems taking the medication, your veterinarian can recommend safe flavoring/compounding options and review any other medicines or supplements for possible interactions.
Front desk script: Lorazepam comes as a tablet or a liquid. Most dogs take it best when it’s hidden in a small treat; if it upsets the stomach on an empty tummy, a small snack with the dose can help. If your dog vomits after a dose or won’t keep it down, please call us before giving another dose—we can ask the doctor about a flavored compounded version. If you see extreme sleepiness, trouble breathing, collapse, or severe agitation, go to the nearest emergency vet right away.
Lorazepam (Ativan) is a Schedule IV controlled substance and is prescription-only. Under federal law, Schedule III–IV prescriptions may be refilled up to five times within six months from the date written; after that, a new prescription is required. Refills must be approved by the veterinarian and an active veterinarian‑client‑patient relationship (VCPR) is required; state rules may add requirements (for example, exam timing or e‑prescribing). Your veterinarian can advise whether a recheck exam is needed before continuing refills.
Refill call checklist: confirm pet and client identity, medication name and form (tablet/liquid), preferred pharmacy (name, city/state), how much is left and the last dose given, any new side effects or behavior changes, and any upcoming events that may affect timing (travel, known stressors). Standard clinic turnaround is typically 1–2 business days; controlled‑substance requests may take longer. Early refills may be limited by law—note reasons like travel if applicable and route to the veterinarian for approval.
Online pharmacy requests: use only licensed U.S. pharmacies that will obtain a valid prescription from the veterinarian. Look for signs of legitimacy (for example, a .pharmacy domain or state licensure) and avoid sites that do not require a prescription. The clinic can send prescriptions directly (e‑prescribe where permitted by DEA and state law, or written), rather than signing pre‑populated forms. If a caller reports severe distress, collapse, trouble breathing, or an active seizure, instruct them to seek emergency care immediately and alert the veterinarian.
Front desk script: Thanks for calling about a lorazepam refill. Because lorazepam is a Schedule IV controlled medication, our doctor must review and approve each refill; we typically need up to 1–2 business days. May I confirm your pet’s name, the medication and form, your preferred pharmacy, how much you have left, and any new concerns you’ve noticed? If the doctor needs a recheck to continue this medication, we’ll contact you to schedule. If your dog is in severe distress or having a seizure right now, please go to the nearest emergency hospital and let us know.
Escalate to a veterinarian or technician immediately if a dog on lorazepam has any trouble breathing (slow, shallow, labored), blue or very pale gums, collapse, unresponsiveness, severe or rapidly worsening sleepiness, cannot stand/walk without falling, or has a sudden change to extreme agitation or aggression after a dose. Treat any suspected extra dose, unknown ingestion, or mix-up with human benzodiazepines as an emergency; bring the pill bottle(s) so the team can see the drug name and strength. Respiratory depression, profound sedation, incoordination, confusion, vomiting, and in severe cases coma can occur with benzodiazepine overdose.
Escalate urgently for possible severe allergic reaction: new facial/muzzle swelling, hives, vomiting/diarrhea with sudden lethargy, or any breathing change—these can progress quickly and need emergency evaluation. Also alert the vet promptly if you notice yellow skin/gums/eyes (jaundice) or unusual behavior changes (paradoxical excitement, increased anxiety). For any questions about side effects or whether lorazepam is appropriate with a pet’s conditions or other medicines, your veterinarian can discuss the plan and risks.
Front desk script: Based on what you’re describing, this could be an emergency related to lorazepam. Please come in now or go straight to the nearest emergency hospital, and bring the medication bottle with you. If you suspect an extra or unknown dose, you can also call Pet Poison Helpline at 855-764-7661 or ASPCA Animal Poison Control at 888-426-4435 on your way. Our veterinarian will advise you on next steps once your dog is assessed.
Key interaction flags with lorazepam (Ativan) in dogs: alert the veterinarian if the pet is also on any central nervous system depressants (for example trazodone, gabapentin, opioids/tramadol, sedating antihistamines), as combined use can increase sleepiness, wobbliness, and—in severe cases—slow or difficult breathing. Other listed interactions include SSRIs such as fluoxetine, tricyclic antidepressants, antacids, carbonic anhydrase inhibitors, hepatic enzyme inducers/inhibitors (for example phenobarbital), and theophylline/aminophylline. Do not advise any dose changes; your veterinarian can discuss if timing adjustments, monitoring, or medication changes are needed. ([vcahospitals.com](https://vcahospitals.com/foster/know-your-pet/lorazepam))
Commonly co‑prescribed medications you may hear from owners: trazodone (for situational anxiety), gabapentin (for anxiety/pain), fluoxetine (behavioral/SSRI), phenobarbital (seizure control), and tramadol/opioids (pain). These fall into interaction categories above—mainly additive sedation/CNS depression or potential changes in drug levels—so flag these for veterinarian review. If an owner mentions over‑the‑counter products, pay special attention to diphenhydramine/“Benadryl” (sedating antihistamine), antacids (e.g., famotidine, omeprazole, Tums), CBD products, and melatonin; these can increase drowsiness with lorazepam or otherwise interact and should be cleared by the veterinarian first. ([vcahospitals.com](https://vcahospitals.com/foster/know-your-pet/lorazepam))
Escalate immediately if the pet has severe lethargy, is hard to wake, shows slowed or labored breathing, collapses, or has unexpected agitation/tremors after a medication mix or possible extra dose—these can be signs of benzodiazepine toxicity or serious interaction; direct the client to the nearest emergency hospital and notify the medical team. Your veterinarian can also advise when to contact poison control if a non‑prescribed human sedative was given.

Front desk script: Thanks for letting me know about the other medications. Some drugs and OTC products can increase drowsiness or change how lorazepam works, so I’m going to flag this for our veterinarian to review today. Please don’t change or skip any doses until the doctor advises. If you notice your dog is extremely sleepy, hard to wake, unsteady, or having trouble breathing, go to the nearest emergency clinic now and call us on the way.
Clinic handling: Lorazepam (Ativan) is a Schedule IV controlled drug—keep clinic stock and filled prescriptions secured in a locked, substantially constructed cabinet with access restricted per DEA/clinic policy. For owner pickup, confirm a child‑resistant cap unless otherwise directed and remind clients to keep the label intact. If there are any questions about formulation or storage on the label, your veterinarian can discuss specifics for that pet.
Owner storage reminders: For tablets, store tightly closed at room temperature (about 68–77°F/20–25°C), with brief excursions allowed, away from heat, moisture, and direct light. If the prescription is the oral concentrate (Lorazepam Intensol 2 mg/mL), it must be kept refrigerated at 36–46°F (2–8°C), protected from light, dispensed only in its original bottle with the calibrated oral syringe, and the opened bottle must be discarded 90 days after first opening—have the owner write the open date on the bottle. If the medication is a compounded liquid, storage temperature and “use‑by” date come from the dispensing pharmacy’s label; defer to the veterinarian/pharmacist if unclear.
Safety and disposal: Emphasize pet‑ and child‑proof storage (locked or well out of reach—never on countertops, nightstands, purses, or backpacks). For unused or expired lorazepam, recommend a drug take‑back site or mail‑back. If no take‑back is available, and because lorazepam is not on FDA’s Flush List, advise disposing in household trash only after mixing with an unpalatable material (e.g., used coffee grounds/cat litter) and sealing in a bag or container; do not flush. If a child or another pet may have ingested lorazepam—or if the pet shows severe sleepiness, trouble breathing, or collapse—treat this as an emergency and seek immediate veterinary care or contact an animal poison control center.
What to monitor: Lorazepam mainly needs clinical (at‑home) monitoring. Watch for expected sedation as well as wobbliness or incoordination, weakness, drooling, or unusual agitation/paradoxical excitement. Your veterinarian may simply ask how the dog is responding; no routine laboratory testing is typically required for lorazepam itself, but the doctor may request exams and labs if use is long‑term or if the pet has liver or kidney concerns or is on other sedating medicines. Do not leave the pet unattended with the first few doses. Improvements in anxiety signs may be seen within 1–2 days. Your veterinarian can discuss exactly when to recheck and whether any bloodwork is needed. ([vcahospitals.com](https://vcahospitals.com/foster/know-your-pet/lorazepam?utm_source=openai))
When to schedule: Book follow‑ups strictly per the doctor’s note. For situational use (e.g., noise or travel), the doctor may want a check‑in after an exposure to see if the plan is working; for ongoing use or medically complex patients, the doctor may set periodic rechecks and possibly labs. Escalate immediately if owners report red‑flag signs: severe or persistent sedation, trouble breathing, collapse, extreme agitation, or yellow gums/eyes—direct them to emergency care now and notify the medical team. ([petmd.com](https://www.petmd.com/dog/poisoning/benzodiazepine-medication-toxicity-dogs?utm_source=openai))
Refills/logistics: Lorazepam is a Schedule IV controlled drug. Under U.S. federal law, Schedule III–IV prescriptions cannot be refilled more than five times or beyond six months from the original date; state laws and clinic policies may be stricter. Ask owners to request refills ahead of running out so the veterinarian can review and authorize. ([law.cornell.edu](https://www.law.cornell.edu/cfr/text/21/1306.22?utm_source=openai))
Front desk script: I’ll follow the doctor’s plan for follow‑up—some pets need only a check‑in to see how lorazepam is working, and the doctor will tell us if labs are needed. Please watch for sedation, wobbliness, or any unusual agitation; if you ever see severe sleepiness, trouble breathing, collapse, or yellow gums or eyes, seek emergency care now and then call us. Because lorazepam is a Schedule IV controlled medication, refills are limited by law, so please request them a few days before you run out. If you’d like, I can confirm the timing of your pet’s next recheck with the veterinarian.
Lorazepam (brand name Ativan) is a prescription benzodiazepine sometimes used in dogs for short‑term anxiety relief and, in clinics, for emergency seizure control. It is a DEA Schedule IV controlled substance, so prescribing, dispensing, and refills must follow federal and state rules; do not share this medication and store it securely away from children and pets. Use in animals is extra‑label under a veterinarian’s direction. ([petmd.com](https://www.petmd.com/pet-medication/lorazepam-dogs?utm_source=openai))
Common effects include sleepiness and unsteady walking. Some dogs can show the opposite reaction (restlessness or aggression). Concerning signs after a dose or accidental ingestion include severe sedation, incoordination, agitation, vomiting, trouble breathing, or collapse—treat this as urgent and seek emergency veterinary care or contact Pet Poison Helpline (855‑764‑7661) or ASPCA Animal Poison Control (888‑426‑4435). ([petpoisonhelpline.com](https://www.petpoisonhelpline.com/poison/benzodiazepines/?utm_source=openai))
Front desk scope: do not provide dosing or timing advice and do not advise starting or stopping lorazepam; your veterinarian can discuss whether it’s appropriate for a specific dog, potential interactions, and monitoring. Refill requests may require veterinarian approval and may take additional time due to Schedule IV requirements. Phrases to avoid: “Give X amount,” “It’s safe to start/stop,” or “It’s fine to use from a human prescription.” ([petmd.com](https://www.petmd.com/pet-medication/lorazepam-dogs?utm_source=openai))
