Acidurin contains ammonium chloride, a urinary acidifier. It lowers urine pH, which vets use as part of managing certain urinary crystals and stones. It is not a treatment for every urinary problem — some crystal types form in acidic urine and would be made worse — so use it only on the advice of your veterinarian, who will set the dose and usually recheck urine pH.
100mg tablets in a bottle of 100. See more in Health Care and the Apex range.
