In some dogs, trying to give them Benadryl to calm them may have the opposite effect and make them more anxious. In addition, Benadryl should not be given to animals with certain health conditions.
Benadryl has some efficacy in the prevention of motion sickness in dogs and as a mild sedative, but the effects are not the same as with people. Some dogs and cats can actually have the opposite reaction to Benadryl, causing hyperactivity instead of sedation.
Happy Thursday! We have our final day of mild conditions ahead of the big changes and severe weather threat that moves in for Friday. Enjoy the fast warm-up we will experience today. After starting in the low 30s we will quickly warm up with a mix of sun and clouds and end up in the 60s by the time we get into the afternoon.
Our mild weather comes to an end starting overnight tonight. Scattered showers and a few thunderstorms will be possible through the early morning hours of Friday. Most of this will be fast-moving and shouldn't impact the morning commute in a major way. The models are still coming together and have pushed the best chance of severe weather off to our northwest. The latest severe weather outlook from the storm prediction center introduced a Moderate (level 4) Risk for areas west of Peoria for Friday evening while maintaining an Enhanced (level 3) Risk for all of Central Illinois. Here is a look at our time frame.

Some allergic responses can be deadly. Some cats react so severely to insects or venomous reptiles that they cannot breathe without immediate veterinary care. This is especially true for brachycephalic or "smush face" breeds, like Persians, that already naturally have compromised airways without the added airway constriction that an allergic reaction can cause.
Diphenhydramine is a first-generation antihistamine with anticholinergic and sedative properties. It is most commonly used for the treatment of nausea, vomiting, allergic rhinitis, mild to severe allergic reactions (e.g., anaphylaxis), and as a mild sleep aid. While used for a wide array of medical indications, diphenhydramine is also one of the most commonly abused medications in the United States (U.S.). Acute intoxications of diphenhydramine can have severe, potentially fatal consequences if not managed appropriately in a timely manner.
Diphenhydramine can also have negative cardiovascular consequences in the setting of toxicity. ECG changes can be observed, which include the widening of the QRS-complex and tachycardia, possibly caused by the anticholinergic effects of diphenhydramine. More specifically, diphenhydramine can affect the delayed rectifier potassium ion channels of the heart as it can act as a blocker of potassium channels. These channels are responsible for the rapid component of the cardiac repolarizing current. This leads to the prolongation of the QT-interval and a flattening of the T-wave. As a result, individuals are at increased risk of developing potentially fatal arrhythmias, such as torsade de pointes.
Vd can also vary between age groups. For pediatric patients, the Vd is approximately 22 L/kg (range: 15 to 28 L/kg). For adult patients, the Vd is approximately 17 L/kg (range: 13 to 20 L/kg) and approximately 14 L/kg (range: 7 to 20 L/kg) for elderly patients. It is extensively metabolized by the liver via cytochrome P450 enzymes. Most of the diphenhydramine that is hepatically metabolized undergoes N-demethylation via CYP2D6, with minor demethylation occurring via CYP1A2, CYP2C9, AND CYP2C19. The drug undergoes metabolism to much smaller degrees in the pulmonary and renal system and is, thus, minimally removed by hemodialysis. Studies have shown that diphenhydramine toxicity is dose-dependent. One retrospective study observed that moderate symptoms, characterized as agitation, confusion, hallucinations, and ECG disturbances, occurred at doses of 0.3 grams. Furthermore, severe symptoms, characterized as delirium/psychosis, seizures, coma, and death, manifested at doses of 1 gram or more.
Patients with diphenhydramine toxicity present with an extension of adverse effects and generally include CNS depression and anticholinergic symptoms. Patients that present with mild to moderate poisoning exhibit more anticholinergic symptoms, which include dry mucous membranes, disorientation, tachycardia, mydriasis, urinary retention, hyperthermia, and decreased bowel sounds. Patients with more severe toxicity may also have severe delirium, seizures, psychosis, hypotension, dystonic reactions, hallucinations, and cardiac arrhythmias (i.e., QT prolongation and QRS prolongation). In rare cases, there are reports of rhabdomyolysis and renal failure in patients with prolonged agitation, coma, or seizures.
If the patient presents within 1 hour of ingestion of diphenhydramine, decontamination techniques may be considered. Single-dose activated charcoal may benefit, especially as anticholinergic effects may result in decreased gastrointestinal motility leading to delayed absorption of diphenhydramine. However, the use of charcoal is avoided in patients with altered mental status unless the airway is protected. Other decontamination procedures such as ipecac, cathartics, or gastric lavage have not been proven to be beneficial or routinely used due to lack of demonstrated efficacy and increased risk of complications.
"If your dog gets bit by a snake, stung by a bee or something, you should take them to the vet if it's real serious, but if they're just having a little allergic reaction, give them some Benadryl that you almost always have in your house. It's probably going to be more cost effective than something that is specifically for dogs," says Mark Mitchell.
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
Dear Doc: I was at a picnic over the weekend where there were lots of different kinds of foods. Being adventurous, I tried a bit of everything. Before long, I started to have trouble breathing, developed a rash, and had to be taken to the emergency room. I was told I had an allergic reaction and had to be treated with Benadryl. I have never had an allergic reaction before and am not allergic to anything I know of.How is this possible? Was it something I ate? How can I tell what it was, and how can I prevent it from happening again? 041b061a72
