The end produtcs are removed through the kidneys or lungs. Excessive administration can cause metabolic alkalosis whic is worse than the metabolic acidosis being treated
Hydrogen Ion + Bicarbonate Ion <> Carbonic Acid <> Water+Carbon Dioxide
Severe acidosis; Cardiac arrest, after ventilation and other problems have been corrected; Tricyclic antidepressent overdose
There are no Contraindications when used in the treatment of severe acidosis
