Alu-tab (Aluminium Hydroxide)

The active ingredient, Aluminum hydroxide found in Alu-tab acts as an oral antacid and phosphate binder. Its primary use in pets is to address high phosphate levels that are often seen in cases of kidney dysfunction. It's important to note that the use of aluminium hydroxide in cats and dogs for these conditions is considered "off label".

The active component, Aluminium Hydroxide functions as a phosphate binder. In cases of kidney dysfunction, the kidneys are less efficient at eliminating phosphate from the body. Elevated phosphate levels can lead to various health problems, including further deterioration of kidney function. When Aluminum Hydroxide is ingested, it binds to phosphate in the intestines. This bound phosphate is then excreted in the faeces, rather than being absorbed into the bloodstream, thereby helping to lower the body’s overall phosphate levels.

In addition, although not its primary use in dogs and cats, Aluminum Hydroxide also has antacid properties. It can reduce stomach acid production, which may be beneficial in pets suffering from certain gastrointestinal conditions. This can help in managing symptoms like stomach ulcers or gastritis, although this is a secondary benefit compared to its role in managing phosphate levels.

Alu-tab is administered orally in tablet form. The medication is usually given just before feeding or mixed into food. It's crucial to follow the veterinarian’s instructions carefully, as the prescribed directions might differ significantly from the label’s suggestions.

Expected Onset and Duration

The effects of Alu-tab generally begin within one to two hours of administration. However, its effectiveness may not be immediately observable, necessitating laboratory tests to evaluate its impact. Typically, this medication ceases working within 24 hours of administration.

Missed dose:

If a dose is missed, it should be given as soon as remembered. However, if it’s almost time for the next dose, skip the missed dose and resume the regular schedule. Avoid giving two doses at once or extra doses.

Overdose:

Overdose can lead to low blood phosphate levels, increased calcium loss, and, in rare cases, aluminium toxicity, indicated by weakness and walking difficulties. If you observe this contact your vet immediately or contact the National Poisons Centre at www.poisons.co.nz/animal-helpline/ or phone 0800 869 738.

Alu-tab should be used with caution in pets with gastrointestinal obstructions or a tendency for constipation.  

This medication can affect the absorption of other drugs. It is typically advised to administer Alu-tab two hours before or after other medications. Notable interactions can include allopurinol and aspirin. Always inform the veterinarian about any other medications your pet is taking.

While generally safe, some pets may experience constipation. If this occurs, contact your veterinarian.

Tablets should be kept in a sealed container, at room temperature and away from moisture. For safety keep out of reach of children and other pets.

Regular monitoring for aluminium toxicity and blood phosphate levels is crucial. Initial monthly checks are recommended, followed by 3 monthly reviews once levels stabilise.

Can Alu-tab be used for any pet?

• This medication is specifically used for cats and dogs. Its use should be based on a veterinarian's prescription.

How quickly does it take for Alu-tab’s to work?

• The effects usually start within 1-2 hours, but laboratory tests are often needed to gauge its effectiveness.

What are the main side effects?

• The most common side effect is constipation. In rare cases, long-term use can lead to aluminium toxicity. Contacting your veterinarian if these occur is imperative.

Can Alu-tab interact with other medications?

• Yes, some medications can affect the absorption. It is important to talk to your veterinarian on how to safely administer medications together.
