Perioperative Considerations Post-operative Advice Aluminium containing antacids should be used with caution in patients with renal impairment, particularly if also prescribed effervescent medications e.g. soluble paracetamol (see Further Information)1, 2. For patients on enteral feeds – see Interaction(s) with other Common Medicines used in the Perioperative Period. Patients Undergoing Anti-Reflux Surgery or Total Gastrectomy |

Interaction(s) with other Common Medicines used in the Perioperative Period |
Administration of antacids containing aluminium, calcium or magnesium might damage enteric coatings designed to prevent dissolution in the stomach and can impair absorption of other medications. If administering medication where a reduction in bioavailability could have a clinically significant effect on safety or efficacy (e.g. antimicrobials), administration of the medication should be separated from the antacid, to allow for appropriate absorption1, 4. Antimicrobials
Consult product literature for recommendations on separating doses to ensure absorption. Iron Corticosteroids Enteral feeds |
