An antibiotic the FDA approves for use in dogs and cats, Albon is the brand name for the drug sulfadimethoxine. Albon is classified to treat bacterial infections and, per the FDA, "enteritis associated with coccidiosis in dogs," an inflammation and infection in the small intestine caused by excessive coccidia protozoa. Albon is available in both pill and liquid form. As with all medication, Albon has certain side effects the dog and its owner may find undesirable.
Doctors Foster and Smith Pharmacy is clear on Albon's Patient Information Sheet that a dog may be allergic to Albon. They list the symptoms of an allergic reaction as "facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma." Doctors Foster and Smith also caution Albon may cause sensitivity to sunlight and recommend a veterinarian be contacted immediately if any of the listed signs are present.
A serious side effect of Albon is arthritic inflammation that--when severe enough--may cause the dog to become lame, according to Doctors Foster and Smith.
Albon may affect the dog's blood health in two ways: anemia and loss of blood. Should the dog become anemic while taking Albon, it will become lethargic. Another sign of anemia is the gums becoming more pale. Dr. Wendy Brooks reports on The Pet Pharmacy's website that Albon may also cause a condition known as blood dyscrasias. Blood dyscrasias is "abnormal blood cells or proportions of different blood cells," says Dr. Brooks. Depending upon which types of cells blood dyscrasias affects, bleeding tendencies like hemophilia may occur. Blood dyscrasias is a syndrome often associated with the arthritic inflammation side effect as well.
A common side effect of antibiotics is vomiting and diarrhea. A dog taking Albon may not only suffer from that, but may also lose its appetite and develop a fever, reports Doctors Foster and Smith and VetInfo4Dogs.com.
Although this side effect is fairly uncommon, keratoconjunctivitis, also known as KCS or dry eye, might appear in a dog on Albon for an extended period. Doctors Foster and Smith report symptoms of KCS are eye redness, discharge and squinting.
Use of Albon may form sulfa crystals in the dog's urine. Provided the animal is well hydrated, Doctors Foster and Smith assure the crystals do not cause any serious problems. VetInfo4Dogs.com, however, warns that should the dog become dehydrated, it may develop a urinary tract infection. Balancing the dog's water intake is critical as well, because Albon causes increased thirst and urination which may damage the kidneys.
