A pharmacist has issued a stark warning on the potential dangers of mixing common medications with a particular fruit juice. According to Ian Budd, a UK-based prescribing pharmacist, statins, blood pressure
tablets, and antidepressants could all be impacted by grapefruit juice. Grapefruit juice is packed with vitamin C and offers benefits like boosting your immunity, supporting skin health through collagen production and protection from damage, and promoting hydration due to its high-water content. However, according to Budd, consuming the juice along with these medications could render the drugs less effective or, even in some instances, heighten the risk of side effects. “Grapefruit and grapefruit juice are one of the most common causes of food and medicine interactions,” Budd told Surrey Live.
Why is grapefruit juice not advised for those with high blood pressure?
According to experts, grapefruit juice contains natural chemicals that block an enzyme in your liver, which helps break down certain medicines. “When that happens, your body cannot process the drug as it normally would, so more of it stays in your system. That can make side effects stronger or more likely,” he added. Chemicals in grapefruit juice inhibit an enzyme known as CYP3A4, responsible for breaking down the medication, according to the Food and Drug Administration. And so, it is important to speak with your doctor before consuming grapefruit or grapefruit juice if you take blood pressure medication, as some drugs are more affected than others, and the effects can last for up to 24 hours. While statins are primarily for high cholesterol, data show a significant overlap in users with those who have high blood pressure. Across the world, over 200 million people take statins, and in the US, over 92 million adults use them. Studies indicate that about 74.9 per cent of those taking statins also take blood pressure medication, though it's important to note that statins are not a primary treatment for blood pressure.Side effects caused by grapefruit juice and statins
