4 Clinical Particulars

4.9 Overdose

Gastrointestinal effects such as nausea, vomiting and diarrhoea may be evident and symptoms of water/ electrolyte imbalance should be treated symptomatically. During the administration of high doses of amoxicillin, adequate fluid intake and urinary output must be maintained to minimize the possibility of amoxicillin crystalluria. Amoxicillin crystalluria, in some cases leading to renal failure, has been observed (see Section 4.4 Special Warnings and Precautions for Use).
Amoxicillin can be removed from the circulation by haemodialysis.
