Rx Vitamins Phos-Bind Powder Main Uses
Management of Hyperphosphatemia: Used to reduce elevated serum phosphorus levels, a common and damaging complication in pets with Chronic Kidney Disease (CKD).
Renal Health Support: Helps slow the progression of kidney disease by preventing the mineralization of soft tissues and secondary hyperparathyroidism caused by high phosphorus.
Dietary Phosphate Binding: Designed to be used alongside or in place of renal-specific diets to limit the amount of phosphorus absorbed from food into the bloodstream.
 
Rx Vitamins Phos-Bind Powder Active Ingredients
Aluminum Hydroxide (USP): A 100% pure, finely ground, "superfine" dried gel powder. Each scoop (depending on bottle size) typically contains 250 mg (1/8 tsp) or 500 mg (1/4 tsp) of USP-grade aluminum hydroxide.
Mechanism of Action: It acts as a "magnet" in the digestive tract. When mixed with food, the aluminum hydroxide binds to dietary phosphorus in the small intestine, creating insoluble aluminum phosphate complexes that are excreted in the feces rather than absorbed into the blood.
Inert Properties: It is tasteless and odorless, ensuring high palatability for pets that may already have a reduced appetite due to kidney issues.
 
Rx Vitamins Phos-Bind Powder Dosage & Administration
Standard Dosage: The general recommended starting dose is 100 mg per kg of body weight daily, divided between meals.
Canadian Specific Sizing (0.625 cc scoop):
≤ 2.5 kg: 1 scoop daily.
2.6–5.0 kg: 2 scoops daily.
7.6–10.0 kg: 4 scoops daily.
Administration: Must be given with meals. It can be mixed into wet food or adhered to dry kibble by adding a small amount of water or oil to the food before mixing in the powder.
Adjustments: Dosage should be adjusted every 2–4 weeks based on serial blood tests (serum phosphorus levels) performed by a veterinarian to reach a specific target range based on the pet's CKD stage.
 
Rx Vitamins Phos-Bind Powder Side Effects & Safety
Common Side Effects: Constipation is the most frequently reported side effect. This can often be managed by adding moisture or fiber to the diet under veterinary guidance.
Safety Warnings:
Monitoring: Use only under strict veterinary supervision. Regular bloodwork is required to ensure phosphorus levels do not drop too low (hypophosphatemia).
Drug Interactions: Can interfere with the absorption of other medications (e.g., tetracyclines, digoxin, or fluoroquinolones). It is generally recommended to separate administration of Phos-Bind from other oral medications by at least 2 hours.
