FAQs: Cytopoint vs. Benadryl

1. What is Cytopoint?

Cytopoint is a cutting-edge monoclonal antibody therapy designed to target and neutralize the cytokine IL-31, a key player in sending itch signals to dogs’ brains. Administered via subcutaneous injection by a veterinarian, its effects can last between 4 to 8 weeks.


  • Longer-lasting relief from itching.
  • Specific targeting of itch-causing cytokines.
  • Minimal side effects due to its natural breakdown in the dog’s body.

2. What is Benadryl?

Benadryl (diphenhydramine) is an over-the-counter antihistamine initially developed for humans but often prescribed for dogs to treat allergies. It functions by blocking histamine receptors, reducing symptoms of allergic reactions.


  • Easily accessible and can be purchased without a prescription.
  • Can treat various symptoms, including itching, swelling, and redness.
  • Well-known and has been used for years in both humans and pets.

3. The Showdown: Cytopoint vs. Benadryl


While Cytopoint offers targeted relief from itching due to its specialized mechanism, Benadryl acts more broadly. Some dogs may not respond to antihistamines like Benadryl, making Cytopoint a potentially more effective choice.


A single injection of Cytopoint can provide relief lasting several weeks. In contrast, Benadryl usually requires more frequent dosing, often several times a day, to maintain its effects.

Side Effects

Cytopoint boasts a natural breakdown in the body, resulting in minimal side effects. Benadryl, on the other hand, may cause drowsiness, dry mouth, or urinary retention in some dogs.


Benadryl is generally more affordable and accessible. However, the repeated doses needed might add up over time. Cytopoint can be costlier upfront but could be economical in the long run due to its long-lasting effects.

4. The Verdict

The best treatment largely depends on the dog’s specific needs, the severity of their allergies, and the owner’s preferences and budget. Some dogs might benefit from a combination approach. Always consult with a veterinarian to determine the best course of action.

  • Benadryl: Long-term usage can sometimes result in increased heart rate, respiratory depression, or hypersalivation. Regularly monitoring and discussing any observations with your veterinarian is crucial.

Q4: My dog didn’t respond to Cytopoint/Benadryl. Does this mean other treatments won’t work?

Answer: Not necessarily. Each dog’s allergic response is unique, and what works for one might not work for another. There are multiple pathways involved in allergic reactions, and if one treatment isn’t effective, another might be. Always explore alternative treatments with your veterinarian.

Q5: Are there natural alternatives I can explore for my dog’s allergies?

Answer: Yes, several natural remedies might help, like omega-3 fatty acid supplements, aloe vera, or oatmeal baths. However, while natural doesn’t always mean safe, it’s vital to discuss any alternative treatments with your vet.

Q6: How do I know if my dog’s itchiness is due to allergies or something else?

Answer: Allergies often present with symptoms like redness, swelling, frequent scratching, or even ear infections. However, other conditions like parasitic infestations, fungal infections, or underlying systemic issues can also cause similar symptoms. Accurate diagnosis via a veterinary examination is crucial before starting any treatment.

Q7: Can environmental changes help in alleviating my dog’s allergy symptoms?

Answer: Absolutely. Depending on the allergen causing the reaction, changes like using hypoallergenic bedding, air purifiers, regular baths, or even dietary modifications can significantly benefit dogs with allergies. Understanding the root cause is key.

Q8: How often will my dog need a Cytopoint injection?

Answer: The frequency varies among dogs. Some might require an injection every 4 weeks, while others can go up to 8 weeks or more between treatments. Monitoring your dog’s symptoms and regular check-ins with your vet will determine the optimal frequency.

Q9: How do Cytopoint and Benadryl function differently in alleviating itching?


  • Cytopoint: It operates as a targeted therapy, specifically neutralizing the cytokine IL-31, a key itch-inducing protein in dogs. By doing so, it directly targets and reduces the itch sensation.
  • Benadryl: As an antihistamine, Benadryl blocks histamine, a compound produced in response to allergens, from binding to its receptors. This prevents the common allergy symptoms, including itching.

Q10: Are there breeds that are more susceptible to adverse reactions from these treatments?

Answer: While no breed-specific contraindications are noted for either Cytopoint or Benadryl, some breeds may have a genetic predisposition to allergies or skin conditions. It’s vital to know your breed’s specific health nuances and work closely with a vet to tailor treatments accordingly.

Q11: Can diet play a role in how effective these treatments are?

Answer: Diet is intrinsically linked to overall health, including the immune system’s response. Some dogs might benefit from hypoallergenic diets or those enriched with specific nutrients that boost skin health. While diet alone might not determine the treatment’s success, it can play a supportive role in managing symptoms.

Q12: Are there specific seasons when my dog might require more frequent treatments?

Answer: Depending on your dog’s allergen triggers, certain seasons may exacerbate their symptoms. For example, pollen-related allergies might be more pronounced in spring and summer. Being observant and adjusting treatment frequency with seasonal changes can help maintain comfort.

Q13: Can I combine other treatments or therapies alongside Cytopoint and Benadryl?

Answer: Many vets often combine treatments to enhance efficacy, but it’s crucial to ensure there’s no adverse interaction between them. Discussing the entire spectrum of treatments your dog is on, even non-allergy related, is important for safe care.

Q14: Do these treatments offer relief from other allergy symptoms, like watery eyes or sneezing?


  • Cytopoint: Its primary function is to alleviate itching, so its efficacy on other allergy symptoms isn’t the central focus.
  • Benadryl: Being an antihistamine, it can indeed alleviate multiple allergy symptoms, including sneezing, runny nose, and watery eyes.

Q15: Is age a factor in determining the suitability of these treatments?

Answer: Age can influence drug metabolism and overall health status. While both treatments are used across various age groups, adjustments in dosage or frequency might be needed for very young or senior dogs. Regular vet check-ups are essential to monitor and adapt treatment protocols.

Q16: If my dog has a chronic illness, should I be concerned about using these medications?

Answer: Any pre-existing condition should be communicated to your veterinarian. While both treatments are generally safe, chronic illnesses might necessitate dose adjustments, increased monitoring, or alternative treatments to ensure no complications arise.

Q17: Are there long-term implications of consistently using Cytopoint or Benadryl?


  • Cytopoint: As a newer therapy, long-term studies are still ongoing. However, the treatment’s specificity (targeting only IL-31) might suggest fewer systemic side effects over time compared to broad-spectrum drugs.
