Medications and dietary supplements to avoid taking with aspirin
Pharmacists and doctors have warned against the dangers of combining aspirin with several common dietary supplements, emphasizing that this medication, one of the oldest painkillers available over the counter, can still cause real harm if used without adequate awareness of its drug interactions. Renowned pharmacist Aukain explained that some dietary supplements increase the risk of bleeding when taken with aspirin, making their combination medically inadvisable.
Pharmacist Karasin stressed that many people overlook a crucial step: openly discussing with a doctor or pharmacist all prescribed and over-the-counter medications, as well as vitamins and supplements. She noted that “aspirin seems familiar because it has been around for generations, but its common availability and over-the-counter status do not mean it is harmless.”
According to medical sources, some dietary supplements most associated with an increased risk of bleeding when taken with aspirin include Ginkgo biloba, known for its blood-thinning effects; garlic supplements in various concentrations; fish oil, particularly at high doses; and vitamin E with prolonged use.
In addition to supplements, Aukain warned against anticoagulant medications such as warfarin, apixaban, rivaroxaban, and clopidogrel, explaining that combining them with aspirin significantly increases the likelihood of internal bleeding. She also pointed out that other common medications, such as prednisone and methylprednisolone, may raise the risk of stomach irritation and bleeding when used concurrently with aspirin.
The warnings were not limited to medications and supplements alone. Aukain highlighted the need to pay attention to the ingredients of some over-the-counter products, such as headache, cold, allergy, nasal congestion, and heartburn medications, as they may contain aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) without the consumer easily noticing.
Regarding diet, sources clarified that most foods, including grapefruit, do not interact with aspirin.
Experts emphasize that the best solution remains open and ongoing dialogue with a doctor or pharmacist before starting any new dietary supplement while taking aspirin, especially for individuals taking multiple medications simultaneously, to avoid serious drug interactions.
