loss of coordination), polyuria, polydipsia, nausea which may be accompanied
by vomiting, pancreatitis and erythematous dermatitis (bromide rash).
Uncommon adverse reactions are behavioural changes such as irritability or
restlessness.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse
reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated
reports).
Side effects may appear in dogs on higher doses of therapy, and symptoms
usually disappear after the dose is decreased. If the dog appears too sedated,
assess the serum concentrations of both bromide and phenobarbital to
determine whether the dose of either should be reduced.
If potassium bromide dose is reduced, serum bromide concentrations should be
monitored in order to ensure that they fall within the therapeutic range.
effect of administration of the product vary between individuals
(see section 4.9)
A high chloride intake can increase the elimination of bromide (see section 4.8).
Therefore, whilst it is not necessary for dogs receiving this product to be on a low
salt diet, an increase in the dog’s salt intake may require an adjustment in
bromide dose. The salt content of a dog’s diet during the treatment period should
not be altered drastically, and should be maintained at a stable level. It is
advisable not to change the dog’s diet during therapy.
i) Special precautions for use in animals
Do not abruptly discontinue therapy as this may precipitate seizures.
This product should be used with caution in dogs with mild or moderate
renal insufficiency, since excretion of bromide is reduced (see section
dietary chloride (salt) intake will decrease reabsorption of bromide by the
kidneys, causing decreased serum bromide concentrations, which could lead to

seizures. Conversely, changing to a diet low in chloride will cause bromide levels
to increase, which could cause bromide intoxication (see section 4.5 i and 4.10).
Loop diuretics (e.g. furosemide) can increase bromide excretion and can lower
the level of bromide in the blood.
Administration of fluids or drug formulations containing chloride can lower serum
bromide concentrations.
Bromide is synergistic with other GABA-ergic drugs such as phenobarbital.
