Anti-itch medications are commonly used in veterinary medicine to help manage itchy skin (pruritus) in dogs. They can be used for a variety of conditions, including allergies, parasites and other skin problems. Most medications are suitable for dogs of different ages, but there are certain types that may not be recommended for young dogs.

There are different types of anti-itch medications and different ways to give them, including tablets, injections and topical treatments such as sprays. Your vet will help you choose the most appropriate medication and dose for your dog based on the cause of their itching and their individual needs. The medical term for itching is pruritus.

What is anti-itch medication used for in dogs?

Anti-itch medication can help manage itching in dogs caused by a range of conditions. Itching can appear as scratching, biting, licking or chewing at themselves. Persistent itching can cause significant discomfort and lead to self-trauma, so reducing the itch can help break the itch-scratch cycle while the underlying cause is investigated.

Anti-itch medication may be used for short-term or longer-term treatment, depending on the cause and severity of the itching.

Common uses of anti-itch medication in dogs include:

• Allergies: including flea, food and environmental allergies

• Skin and ear infections: Reducing itching can help prevent further irritation and self-trauma while the infection is treated.

• Parasites: Some parasites can cause intense itching. Appropriate parasite treatment is also needed to address the underlying cause.

How does anti-itch medication work in dogs?

There are many treatment options available to help control itching and inflammation. Your vet will choose the most appropriate treatment based on your dog's symptoms, health and individual circumstances.

Prescription medications

• Corticosteroids: Medicines such as prednisolone can quickly reduce inflammation and itching. They can be given as tablets, injections or topical treatments such as sprays and creams. Topical treatments may be suitable when itching or skin lesions are mild and localised, while other forms may be used for more widespread or severe symptoms.

• Immunomodulating medication: Ciclosporin can be used for longer-term management of allergic skin disease. It works by modifying the immune response that contributes to allergic inflammation.

• JAK inhibitors: Medicines such as oclacitinib, ilunocitinib and atinvicitinib work by blocking specific pathways involved in itching and inflammation. They can provide rapid relief from itching and may be used for short-term flare-ups or longer-term management, depending on the individual dog.

• Antibody injections: Lokivetmab is an injection that targets a specific protein involved in the itch pathway. It can provide relief from itching for several weeks in many dogs and can be repeated as needed, depending on your dog's response.

• Allergen-specific immunotherapy: This involves giving gradually increasing amounts of the allergens your dog has been identified as sensitive to, with the aim of changing the immune response over time. It is usually considered for longer-term management and is tailored to the individual dog. It can be effective in some dogs, but not all dogs respond to treatment.

Over-the-counter options

• Supplements containing omega-3 fatty acids can help support healthy skin. They can be useful as part of a wider treatment plan for allergic skin disease, although they are not a replacement for other treatments when these are needed.

• Topical products containing ingredients such as antiseptics can also help manage irritated skin and reduce excess bacteria or yeast. These may include shampoos, mousses, or pads and can be used alongside other treatments when recommended by your vet.

Your vet may recommend one or more of these treatments depending on your dog’s symptoms, how severe they are, and how they respond to treatment. It can take some time to find the approach that works best for an individual dog, and a combination of treatments may be used to keep their symptoms under control and maintain their quality of life.

How to use anti-itch medication in dogs

Always follow your vet's instructions when giving medication to your dog.

• Giving more than prescribed or missing doses can affect how well the medication works and may increase the risk of side effects.

• Do not change the dose or stop the medication suddenly unless your vet advises you to. Some treatments need to be reduced gradually, particularly after longer courses or higher doses.

• Some medications may need to be given with food or at a specific time of day. Follow the instructions provided by your vet.

If your dog needs anti-itch medication for a longer period, your vet may recommend regular check-ups to assess their response to treatment and monitor for side effects. Some medications may also require blood tests during long-term treatment. The type and frequency of monitoring will depend on the medication your dog is taking and their individual health.

Most common side effects of anti-itch medication in dogs

The possible side effects of anti-itch medications vary depending on the type of medication and how it is given.

They may include:

• Increased thirst, urination or appetite

• Lethargy

• Panting

• Vomiting or diarrhoea

• Drooling

• Changes to the skin or gums

• Redness, swelling or itching at an injection site

• Allergic reactions

Your vet will discuss the potential side effects of any medication prescribed for your dog and advise you what to lo

ok out for. Contact your vet if you notice any concerning signs after starting treatment.

What to do if your dog shows any of these problems

Speak to a vet if your dog develops any new or concerning symptoms. They can advise whether the symptoms could be related to the medication and what to do next.

What to expect from treatment

Anti-itch medication can be an important part of managing your dog’s comfort, but it is not always the only treatment needed. Your vet may look for and treat the underlying cause of the itching, which often includes allergies, parasites or an infection.

There are several different anti-itch treatments available, and the best option will depend on your dog’s symptoms, the cause of their itching and how they respond to treatment. Your vet may recommend one treatment or a combination of treatments, and this may change over time as your dog’s needs change.

If your dog needs anti-itch medication for a longer period, regular check-ups may be recommended to monitor their response and check for any side effects.
