Phos-Bind Powder for Dogs and Cats

Phos-Bind Powder for Dogs and Cats

For dogs and cats.

Product Description

Phos-Bind is a plain aluminum hydroxide powder from Rx Vitamins, used to bind dietary phosphorus in pets with reduced kidney function.

When the kidneys stop clearing phosphorus efficiently it accumulates in the blood, and elevated blood phosphorus is one of the better established drivers of how quickly kidney disease progresses. A phosphate binder works in the gut rather than the bloodstream. Mixed into food, the aluminum hydroxide binds phosphorus from that meal so it passes out in the stool instead of being absorbed.

What sets this one apart is that it is only aluminum hydroxide, with nothing else added. That matters when your veterinarian is adjusting a dose against bloodwork, since there is no second ingredient to account for, and it layers cleanly on top of a renal diet or other kidney supplements without overlapping them.

It is an unflavored fine powder and mixes into wet food readily.

Active Ingredients Per 1 Scoop (1/4 tsp)

• Aluminum hydroxide USP, 500 mg

How to Use

Follow your veterinarian's direction. The label directs 100 mg per kg of body weight daily, given with meals.

Give it with food rather than between meals. A binder only acts on phosphorus that is in the gut at the same time it is, so timing it to the meal is the whole point.

Expect the dose to change. The label calls for adjusting it against serum phosphorus rechecked every 2 to 4 weeks, so the starting amount is a starting point rather than a fixed dose.

Additional Information

For dogs and cats. This is a nutritional supplement, not an FDA-approved drug.

Safety in pregnant or breeding animals has not been proven. The manufacturer notes that aluminum toxicity has not been found to be a concern in dogs and cats at label doses.

Talk to your veterinarian

Phosphate binders are dosed against bloodwork rather than by eye, so this is one to start with your veterinarian and to keep the recheck phosphorus levels they schedule.

Mention everything else your pet takes. A binder sitting in the gut can reduce absorption of medications given at the same time, so spacing them apart is sometimes needed.
