Experienced and professional animal trainer provide their insights in answering this question :
A. While this is not a commonly used drug in veterinary medicine I can find some references that vets have used it at 2mg/kg. At 90 pounds your dog is about 40 kilos, so the suggested dose for him would be 80 mg. So at 150 mg you might see signs of “serotonin syndrome”, which could include a lot of things including diarrhea, increased heart rate and breathing rate, confusion, stumbling, and high blood pressure. I would advise taking him in to a vet so that they can induce vomiting and try to get the pill out, and then treat as appropriately if toxicity signs occur.

Contact your veterinarian immediately. Your veterinarian may instruct you to induce vomiting, however, do not induce vomiting unless instructed to.
Venlafaxine (Effexor©)

Cats ingesting this medication may show clinical signs for 24 to 48 hours. Treatment is the same as other SSRI drugs: emesis and activated charcoal if asymptomatic, monitor the cardiovascular system and watch for tremors and seizures.

Dosage for depression

Dosage increases: If needed, your doctor may increase your dosage to 150 mg per day. Typical maximum dosage: 225 mg per day. If you have more severe depression, your doctor may prescribe a dosage as high as 375 mg per day, taken in three divided doses.

Usual Adult Dose for Depression

Maintenance dose: 75 to 150 mg orally per day, given in divided doses. Maximum dose: Moderately depressed outpatients: 225 mg/day.

Contact your veterinarian immediately. Your veterinarian may instruct you to induce vomiting, however, do not induce vomiting unless instructed to. Bring the medication your animal ingested along with the label or package insert to allow your veterinarian to calculate the dose received.
The toxic dose varies by drug with Venlafaxine having the highest risk of toxicity in overdose: ingestion of >2 g is associated with seizures and serotonergic toxidrome. ingestion of >5 g is associated with a 50% risk of seizures. ingestion of >8 g is associated with cardiotoxicity.
Antidepressants (e.g., Effexor, Cymbalta, Prozac, Lexapro) – While these and other antidepressant drugs are occasionally used in pets, overdoses can lead to serious neurological problems such as sedation, incoordination, tremors and seizures.
SSRI toxicity occurs due toan increased level of serotonin in the central nervous system. If an animal ingests multiple types of antidepressants, they may develop serotonin syndrome which can be life threatening.
Venlafaxine XL 150 mg is a treatment for adults with depression. It is also a treatment for adults with the following anxiety disorders: generalised anxiety disorder, social anxiety disorder (fear or avoidance of social situations) and panic disorder (panic attacks).
A second 8-week study evaluating Effexor XR doses of 75 and 150 mg/day and placebo showed that both doses were more effective than placebo on some of these same outcomes; however, the 75 mg/day dose was more consistently effective than the 150 mg/day dose.
Is there any food or drink I need to avoid? You can eat and drink normally while taking venlafaxine.
So it takes about 5 hours for your body to get rid of half of a dose of Effexor XR. It usually takes about four to five half-lives for a drug to leave your system entirely. For Effexor XR, this means the drug will stay in your system for about 25 hours.
Call your veterinarian immediately if you suspect your dog to have consumed un-prescribed doses of antidepressant medications. Your veterinarian may recommend you induce vomiting in your pet by oral administration of hydrogen peroxide. Transport your pet to your veterinarian as per their recommendations.
Pet poisoning due to these accidents are common and can be very serious. If your dog eats pills for humans, it can be very scary. You`ll likely need to call your veterinarian right away, especially if you suspect what they`ve swallowed is potentially poisonous.
Many different drugs can cause poisoning in dogs when they are not given as prescribed. This is especially true of medications that were intended for humans. Veterinarians define medication overdose in dogs as drug poisoning. Depending on the drug and the amount ingested, this can cause serious illness and even death.
are trying to become pregnant, are already pregnant or you are breastfeeding. have glaucoma – venlafaxine can increase the pressure in your eye. have epilepsy or are having electroconvulsive treatment – venlafaxine may increase your risk of having a fit or seizure.
Descriptions. Venlafaxine is used to treat depression. It is also used to treat general anxiety disorder, social anxiety disorder, and panic disorder. Venlafaxine belongs to a group of medicines known as serotonin and norepinephrine reuptake inhibitors (SNRI).
One study found that Effexor was one of the most effective antidepressants. 5 While Effexor can be a strong antidepressant, individual effects and tolerance may vary.
Venlafaxine can provoke dose-dependent blood pressure elevation, sometimes requiring treatment discontinuation. Exposure to venlafaxine during the second and third trimesters of pregnancy increases the risk of pre-eclampsia and eclampsia.
#1: Non-steroidal anti-inflammatory medications and cats

Acetaminophen (i.e., Tylenol) — Ingestion can cause anemia, liver toxicity, and kidney disease. One regular strength pill can cause toxicity within three hours of ingestion, and two pills can be deadly.

Drugs can be fatal or cause long-term damage in pets. Some of the symptoms that pets experience after ingesting medication can include stomach upset, elevated heart rate, lethargy, and loss of coordination.
Toxicity to pets

At even therapeutic doses, it can result in moderate to severe clinical signs. With accidental poisoning or ingestion, clinical signs from SSRIs include sedation or central nervous system (CNS) stimulation, anorexia, and lethargy. With larger poisonings, serotonin syndrome can be seen.

Overdose symptoms have been reported in doses as low as 200 mg. SSRIs: Typical dose of SSRIs is between 20 and 80 mg daily. SNRIs: Typical dose ranges from 75 and 225 mg daily. Overdose symptoms have been reported in doses as low as 2,000 mg.
The recommended starting dose for prolonged-release venlafaxine is 75 mg given once daily. Patients not responding to the initial 75 mg/day dose may benefit from dose increases up to a 300 mg/day dose and a maximum dose of 375 mg/day.

Q. My 90lb swallowed a Venlafaxine – 150mg Er Cap , do I need to take him to the vet:?
ANSWER : A. While this is not a commonly used drug in veterinary medicine I can find some references that vets have used it at 2mg/kg. At 90 pounds your dog is about 40 kilos, so the suggested dose for him would be 80 mg. So at 150 mg you might see signs of “serotonin syndrome”, which could include a lot of things including diarrhea, increased heart rate and breathing rate, confusion, stumbling, and high blood pressure.

Q. My kitten has a very bloated stomach. Do I need to see a vet or do I buy a dewormer? we just found this kitten on the side of the road.
ANSWER : A. If it is a stray then you need to see your vet as soon as possible for a full examination. Yes you need a wormer but you need a good quality one from your vet, the over the counter ones are not as effective. You also need to treat for fleas and get vaccines. Your vet will be able to do all this and check that there aren’t any other medical problems that need attention.

Q. We think our dog had a stroke:( he is 14 years old, a cocker spaniel mix. Do we need to take him to an emergency vet or should he be fine until mornin
ANSWER : A. If it was a stroke (vestibular syndrome) there is little the vet will do for the first 24-48 hours apart from giving an anti vomiting injection. You need to wait and see how well the dog responds after the episode to see if he fully recovers, sometimes they partially recover but may end up with a head tilt.
If it was a seizure they normally only last seconds and then within an hour the dog is back to normal. Again you don`t need to consult your vet straight away but monitor him. Some dogs may have one seizure but never again. If this is what it was then see your vet if your dog has another one.

Q. My dog is a rake of bones after nursing nine puppies I have her on a multivitamin fish oil milk replacer and have wormed her she is on fromm pup food
ANSWER : A. There is a formula that will give you a rough guideline of caloric needs. Take yours dogs healthy body weight in lbs and divide by 2.2. This is now your dogs weight in kg. Take this weight and multiply by 30. To this number, add 70. This final number is considered your dogs Resting Metabolic Rate. Take this number (RMR) and multiply it by 4. This will be the low end of calories needed. Now take the RMR and multiply by 8. This is the high end of calories needed. Almost there… One more step… On the back of the dog food you can see how many kcal/cup of dog food. If you divide the caloric need ranges by this number you will see how many cups of food daily. I hope this helps. Please consult with me if you want me to go through this with you.

Q. How do I know if I am losing my cat. She is 8 and weighs about 20lbs. She is having issues breathing and I don’t have any money to take her to the vet
ANSWER : A. Your cat really should be seen by a vet. Her weight may be the only thing causing her breathing problems, but without an exam, there’s no way to know for sure.

Q. What are the ways and/or steps to become a veterinarian?
ANSWER : A. Being a veterinarian is a rewarding career, but does involve a lot of schooling, experience and knowledge. Many people try out veterinary medicine through being a tech or assistant first, then continue on to veterinary school if they decide that is the path for them. If you are still in high school, the best way to start gaining experience is just by volunteering at your local animal shelter. Some clinics will also hire kennel technicians, a good starting job that gets you into a clinic and viewing procedures while working your way up. You can major in anything you want in college, however there are class prerequisites that must be met to apply for vet school. Majoring in a degree program such as biology, zoology or animal sciences often meets these requirements without having to take extra classes. Working summers as a tech or assistant, staying active in local animal groups and maintaining a high GPA will make you an ideal candidate. Once you are ready to apply for vet school you will need to take a GRE which is an exam graduate and medical schools use to determine how well you might do. Vet schools tend to look for applicants who are active in the community, have experience and have good grades. If considered, you will then have an interview to determine if you’re a good fit! Vet school itself requires four years, the first two focused on classroom and theory subjects such as anatomy, physiology and pathology. Your third year becomes more hands on with lots of labs and “shadowing” of vets in the school. Fourth year is usually entirely clinical rotations to give you a taste of all the things veterinary medicine offers!

Q. I just adopted my cat, about 7 months old, and he has discharged, a greenish color, coming from his eyes. Was told it was stress but what else?
ANSWER : A. I would call the rescue and explain your concerns. I wouldn’t think green mucus coming from eyes means stress and maybe whoever told you that was trying to just brush off the symptoms has nothing to worry about. Rescues normally guarantee the health of their animals and should cover the cost of medical bills if you need to take the cat into the vet. Green color can mean infection. Is the cat sneezing? Could it be an upper respiratory infection? Try to explain to the rescue they need to take the animal into the vet. If they aren’t interested in helping please take the cat to the vet as soon as you can. Make sure to bring all records you have on the cat incase the doctor’s office see’s any mistakes or missing fecal tests/vaccinations they would like to do at a later date with the cat (If the cat is sick they would never give vaccinations the same day).

Q. My dog cracked his nail horizontally, I put neosporine on it with gauze and a sock for no snagging. What should I do and what would a vet cost?
ANSWER : A. It depends on how deep it’s cut and if it’s going to snag on something and rip the entire nail off. It would probably be best to go to the vet now rather than later when a more serious injury occurs. The cost really depends on where you live and what the vet decides to do. I really can’t give much of an estimate other than the initial cost of a sick exam (which also varies from vet to vet). Call the vet and when you make the appointment ask how much a sick exam costs, that will be your initial payment (Amount just to see the vet).
