Moderate, acute overdosage may result in belching and gastro-intestinal disturbances. Treatment would be withdrawal of the product and symptomatic measures, as appropriate.
Severe acute overdosage may precipitate sodium overload (hypernatraemia or hyperosmolality) and possibly metabolic alkalosis. Symptoms may include restlessness, weakness, thirst, reduced salivation, dizziness, headache and possibly hypotension and tachycardia.

Acute ingestion of the neat powder may lead to gastric irritation, gas liberation and possibly stomach perforation. Treatment would be gastric lavage and general supportive and symptomatic measures.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
This product is an antacid.
Sodium bicarbonate ) These react in the glass of water to produce sodium
Sodium carbonate ) citrate, which has antacid buffering properties, and
Citric acid ) carbon dioxide which facilitates eructation. A slight
excess of sodium bicarbonate remains with a small, direct acid neutralising contribution.
5.2 Pharmacokinetic properties
Since the antacid combination acts locally in the stomach and the components are all dissolved, a consideration of their systemic bioavailability and pharmacokinetic behaviour is not appropriate to safety and efficacy considerations.
Residual sodium and citrate ions available for absorption are safely handled by the body and excreted by normal metabolic routes.
5.3 Preclinical safety data
Preclinical safety data on these active ingredients in the literature, have not revealed any pertinent and conclusive findings which are of relevance to the recommended dosage and use of the product.
