Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and reduce inflammation. Antacids are medications used to neutralize stomach acid and treat conditions such as heartburn and indigestion.

According to a study published in the Journal of Clinical Pharmacology [2], taking antacids with ibuprofen may decrease the absorption of ibuprofen, resulting in decreased effectiveness of the medication. Therefore, it is recommended to take ibuprofen at least 30 minutes before or 2 hours after taking an antacid to avoid any potential interaction.

Additionally, the website of Alberta Health Services [3] advises against taking ibuprofen or other NSAIDs with antacids as they may increase the risk of stomach irritation, bleeding, and ulcers. It is important to consult with a healthcare provider before taking any medication, especially if you have a history of stomach problems or other medical conditions.

In conclusion, it is not recommended to take Advil (ibuprofen) with antacids as it may decrease the effectiveness of the medication and increase the risk of stomach irritation, bleeding, and ulcers. It is important to follow the instructions on the medication label and consult with a healthcare provider before taking any medication.
