If a negative reaction occurs, please call your veterinary office.

The term hypercalcemia is used when the level of calcium in the blood is higher than normal. Calcium levels are controlled by a pair of parathyroid glands. High calcium levels may signal the presence of serious underlying disease including kidney failure, adrenal gland failure, a parathyroid gland tumor, and some types of cancer. Pets with hypercalcemia may show signs of weakness, listlessness, increased drinking and urination, and loss of appetite. Your veterinarian will perform diagnostic tests which may include total calcium, ionized calcium, albumin, and parathyroid hormone levels.

Hyperlipidemia refers to elevated levels of lipids (fats) in the bloodstream and can be due to several causes. Often times there are no clinical signs. Hyperlipidemia is confirmed using a 12-18 hours fasting sample. The pet's medical history and a search for an underlying cause is important for its treatment. If no underlying cause is found, your pet will need to start eating a low-fat, high-fiber diets, and may be started on the appropriate medications and supplements.

Hyperthyroidism is a common condition in older cats caused by excess thyroid hormone release resulting in an increased metabolic state. Hyperthyroidism can cause weight loss despite a good appetite, increased water consumption and urination, vomiting, diarrhea, cardiomyopathy, and hypertension. Diagnosis is made by testing blood thyroid hormone levels. Several successful treatment options exist, including medication, thyroidectomy, radioactive iodine, and a prescription diet. The prognosis with treatment is generally good.

Calcium is a mineral that is found in small quantities throughout the body and plays an important role in muscle contraction, transmission of nerve impulses, blood clotting, and bone growth. Hypocalcemia means that the level of calcium in the bloodstream is low. Early signs of hypocalcemia include restlessness, stiffness, weakness, irritability, muscle tremors and hypersensitivity (exaggerated responsiveness) to touch and sound. Calcium and phosphorus levels are closely inter-related and when phosphorus levels increase as a result of chronic kidney disease, calcium levels decrease. With hypocalcemia due to chronic renal failure, treatment is directed at lowering the serum phosphate concentrations by dietary restriction of phosphorus and administration of intestinal phosphate binders. Hypocalcemia may also occur with lactation in a nursing mother cat, low blood protein levels, pancreatitis, certain drugs and toxins, and as a post-operative complication following surgical treatment for hyperthyroidism. If the hypocalcemia is severe, immediate correction of the decreased levels will require calcium injections.

Hypochlorous acid (HOCl) topical is used for the management of skin conditions such as wounds, abscesses, cuts, abrasions, skin irritations, ulcers, post-surgical incision sites, and burns. It may be used to prevent or treat bacterial skin infections, including methicillin-resistant staphylococcus aureus (MRSA). Hypochlorous acid also has antifungal and antiviral properties and is reported to reduce inflammation, pain, and itching.

Hypokalemia is a term that refers to a low blood concentration of potassium. Potassium is an important electrolyte within the body and is vital for the normal function of muscles and nerves. Mild to moderate hypokalemia often does not cause clinical sigs, but severe hypokalemia can result in generalized muscle weakness, lack of appetite, and some cats may become constipated. The underlying cause of hypokalemia is often chronic kidney failure. Hypokalemia and its associated clinical signs may be quickly corrected by potassium supplementation. Depending on the cause, it may be necessary to continue supplementing potassium permanently.
