It has been found that ranitidine (Zantac), contains an impurity called N-Nitrosodimethylamine (NDMA), a probable human carcinogen. Zantac is one of the most common over-the-counter medications used my millions of people around the world.

Still many questions are still out there about whether or not it is safe to take this medication, but as a precaution, I would strongly suggest that you do not, and that you share this information with anyone you know that might be taking it.

Listen to the below podcast if you have time, or if you’d like a brief and hastily-written summary, please read on!

Find a link to Dr. Peter Attia’s podcast “the drive” here, or from your favorite player. This particular podcast, #75 with David Light, speaks about a recent Zantac recall. During the interview, it is explained in detail the timeline of this issue, and how the FDA has moved on this information.

David Light is the CEO of Valisure, the company which alerted the FDA to the cancer concerns of Zantac back in June, and then filed a citizen petition on September 13, 2019. Valisure is an online pharmacy that tests all of its medications. We’ll get into, at another time, the dangers and fraud surrounding certain generic medicationsand manufacturers, but for now we’ll focus on this particular drug.

I would like to emphasize that this carcinogen, NDMA, is certainly a well-studied impurity, which is widely used in animal studies to induce cancer. Valisure found that through testing this product (and all products containing ranitidine, not just one brand or manufacturer), that they were ALL unstable and resulted in dangerous amounts of NDMA concentrations. Other studies that were cited in this podcast found dangerous amounts in urine and blood.

Since these announcements and discoveries, FDA has taken a very laid-back approach to this information, treating it like no big deal. This is a little scary, and there is a lot of information to back this up. Even if there is no issue, and all these studies are debunked, it’s still a silly idea for us to keep taking this medication. It’s not a life-saving medication, nor is this a life ending disease. There are alternatives, and if you are experiencing heartburn then there’s probably something going on in your system and our acupuncturists, herbal doctors, or functional medicine providers could help you get to the bottom of your discomfort.

OTC Alternatives (not the best, but they’re not Zantac!):
*Prilosec, Tums, Malox, Mylanta
–Just because I prefer medications that help to cure the underlying issue, and most meds just cover up the symptoms.

If you do have some of this in your medicine cabinet, and want to get rid of it, please dispose of responsibly! Most pharmacies have a way to dispose of medication – please do not throw away and DO NOT flush down the toilet. I’m not interested in this getting in our water.
