There are plenty of antibiotics out there, and they are all formulated to treat different kinds of issues. Some of the antibiotics that we humans use can even be prescribed for our horses, too! One example of an antibiotic such as this is SMZ. Read on to learn more about the antibiotic SMZ, including what it is and what sorts of ailments it is prescribed to treat— we will also go over how much of the medicine to administer to your horse when needed.

What Is SMZ?

Of course, the first question is, what exactly is SMZ? SMZ is an antibiotic, and it is a combination of two antibiotics that are known as sulfamethoxazole and trimethoprim. Typically, SMZ is an oral antibiotic that can be administered either in paste or in tablet form.

This combination antibiotic can be used to treat many different kinds of bacterial infections and is used for humans, animals, and horses. Of course, for the purpose of this article, we will be discussing how SMZ pertains to our equine partners specifically. We will go over the different types of infections that it can treat in more detail below.

What Does SMZ Do For Your Horse?

As mentioned above, SMZ is a combination antibiotic. There are several different kinds of infections that it is able to treat and may be prescribed by your vet to target. SMZ is known as being effective against gram-negative bacteria and gram-positive bacteria, too. Examples of these kinds of bacteria are E. coli and Listeria monocytogenes.

The most common uses for SMZ are to treat bacterial infections that affect areas of the body such as the middle ear, urinary tract, intestines, and respiratory system. In addition to this, SMZ has been found to be effective in treating a specific kind of pneumonia. This pneumonia is known as pneumocystis type, and can be found in both humans and animals. When it occurs in horses, it usually appears in foals and steadily worsens if not treated.

How Much SMZ Should You Give Your Horse?

Of course, the most important rule when administering SMZ or any antibiotic or medication is to follow the directions given to you by your vet. Typically, though, the rule of thumb for SMZ is to give your horse a dosage based on their mass. They should be given 75 to 100 milligrams of SMZ for every kilogram of their body weight. It is important to follow these instructions carefully to avoid side effects that could possibly occur from consuming too much of the medicine.

Some of the side effects of SMZ include issues like nausea, vomiting, and loss of appetite. They may also have allergic reactions or diarrhea. Some invisible symptoms of SMZ  include issus like anemia— a decrease in red blood cells— and leucopenia— a decrease in white blood cells. If your horse is exhibiting any of these symptoms, you should contact your vet at once and cease administering the antibiotic to your horse in the meantime.
