A Guide to the 5 Most Common Pet and Animal Medications
Caring for your pets or animals, whether they’ve got paws, hooves, feathers or fur, means being ready for the unexpected. From family pets to barn cats and from backyard chickens to horses, keeping them healthy is a top priority, and having easy, affordable access to common pet and animal medications from a trusted online pet pharmacy makes it easier.
For everyday care and for unexpected health issues, knowing the role pet medications play can make all the difference for your dog, cat, horse or herd.
Our pet and animal pharmacy has rounded up the five most commonly prescribed pet, horse, and livestock medications to help you feel more informed.
1. Antibiotics
When a bacterial infection occurs, antibiotics are often the first line of defense. These medications are used to treat infections in the skin, ears, respiratory tract, urinary system and more. Common examples include Amoxicillin, Cephalexin and Clavamox.
Antibiotics work by either killing the bacteria or by preventing them from multiplying, giving the immune system a better chance to fight. As with any medication, antibiotics must be used correctly. That’s why it’s important to follow your vet’s instructions closely and always finish the full course, even if your animal seems better. Using pet or animal antibiotics incorrectly can lead to antibiotic resistance, making future infections harder to treat.
Watch for side effects like vomiting, diarrhea, or allergic reactions. And never use leftover meds from a previous illness, as they may be ineffective or even harmful.
2. Parasite preventatives
Parasites like fleas, ticks, heartworms, mites and worms can affect everything from your dog’s comfort to your horse’s performance. In some cases, parasites pose a serious health risk, including weight loss, digestive problems, anemia, and other life-threatening complications.
Administering parasite preventatives is one of the most important steps in preventing disease and discomfort in pets and animals. Tractor Supply Rx offers a large selection of top flea and tick preventatives, heartworm prevention, and dewormers in oral, topical, and injectable forms.
For best results, most vets recommend applying parasite prevention year-round. Always follow the package instructions or your vet’s advice when administering flea, tick, and heartworm prevention to avoid overdosing, which can be dangerous, and to avoid underdosing, which leaves your pet or animal vulnerable to infestations.
3. Non-steroidal anti-inflammatory drugs (NSAIDs)
From joint pain to post-surgery recovery, NSAIDs help manage pain and inflammation. Common choices include Carprofen (Rimadyl), Meloxicam (Metacam) and Deracoxib (Deramaxx).
These medications block the enzymes that cause swelling and discomfort, so they are often prescribed for conditions such as arthritis, soft tissue injuries, or age-related pain. Because NSAIDs can affect kidney and liver function, your vet may recommend bloodwork before and during treatment to ensure safe, long-term use of this pet medication.
4. Calming and anti-anxiety medications
Behavioral issues like anxiety, aggression, or fear can take a toll on both animals and their owners. When training alone isn’t enough, your vet may prescribe dog and cat calming medications such as Fluoxetine (Reconcile/Prozac), Clomipramine (Clomicalm) or Alprazolam (Xanax).
These cat and dog calming medications help to stabilize mood and reduce anxiety or compulsive behavior. They work best when combined with training and positive reinforcement. If your pet or animal is exhibiting signs of behavioral distress, consult your veterinarian to explore a comprehensive treatment plan.
5. Steroids (Corticosteroids)
When inflammation is severe, whether from allergies, immune conditions or trauma, steroids can provide fast, effective relief. Vets often prescribe Prednisone, Prednisolone or Dexamethasone to control symptoms and calm the immune system.
Steroids help to reduce swelling and block inflammatory responses at the cellular level. But long-term use can come with risks, including increased hunger, thirst, weight gain, and a weakened immune system. Your vet will work to keep doses low and duration short, balancing relief with safety.
