Claritin Allergy Drug Could Hold the Key To Killing Lyme Disease

FROM: Rodale News, “Common Allergy Drug Could Kill Lyme Disease”:

“A popular drug that targets allergy symptoms could also kill off Lyme disease germs, a new study suggests. A study, funded by the Bay Area Lyme Foundation and conducted by Stanford School of Medicine researchers, shows that loratadine (marketed as Claritin), a common antihistamine frequently taken to treat allergy symptoms, may be able to help kill Borrelia burgdorferi, the bacteria associated with Lyme disease that’s often transmitted by ticks.”

“Our results bring us closer to the possibility of discovering the first targeted therapy to treat Lyme disease,” says Jayakumar Rajadas, PhD, Director of the Biomaterials and Advanced Drug Delivery Lab (BioADD), Stanford School of Medicine, and lead author of the study. “It’s exciting to see first-hand that our insights into the metabolic activity of this elusive bacteria may give us the ability to actually kill it.”

The results of this new laboratory study show that loratadine and specifically its metabolite, desloratadine, are able to prevent manganese (Mn) from entering the cell wall of the bacteria that causes Lyme disease, starving the bacteria and causing it to die in test tubes. The antihistamine accomplishes this by inhibiting the bacteria’s transport system.

Manganese is required for certain metabolic processes of Borrelia burgdorferi and also plays an important role in numerous biological processes in the human body. Previous research shows that in general, bacteria scavenge the body for trace metals that circulate in the blood and have developed special adaptations on their cell walls to internalize these metals. Lyme transport protein important to Lyme germs, BmtA, binds with manganese to bring it into the bacteria, and studies have shown that BmtA and manganese are required to make the bacteria harmful to the human body.”

    I have Lyme Disease for almost 4 years now. Was treated late (5 months after symptoms and rash occurred) with intravenous drugs for one month. Was not cured.
    As soon as I read this today went out and bought Claritin and took the 24 hour dose. Already head fog, vision disturbance and itchy skin rash is dissipating. Hope it continues. Also I will watch not to take extra manganese(which I was taking).
    Thank you, thank you, thank you!!!!!!

    Thank you so much for sending me this article.

      My comment is about Claritin & its effect. I have breast cancer & am on a medication Aromasin for 5 years. However, the bone & joint pain is unbearable. I would not be able to stay on it if I didn’t happen upon hearing about Claritin, 24 hr. 10mgs, 1 x day from a friend. I bought it immediately and within 24 hrs., 90% of my pain has disappeared. I will take this Claritin for as long as I can, as it is certainly a wonder drug…I have no idea how or why it works so well but please pass this on to friends & family because it is truly a life saver. You have nothing to lose by taking this, it’s easy (the generic brand even works and the cost is minimal).

      Hello Dolores how are you doing. I have a 15 year old who might have lyme disease. we are waiting to se a specialist. We took him a week after he was bitten and was given 21 days of antibiotic. I read the article of Claritin and was also going to go and buy it and give it to my baby. But my husband said its best to wait to see the Doc on Dec 15. Just curious if its working?

    My husband has Lymes in Florida. Test never came back positive but he had the rash for several years and our PCP didn’t know what it was so he just kept giving cream. Finally we changed PCP and he immediately diagnosed as Lymes rash. We really need a doctor who will treat him. His test do not come back positive but he has headaches, loss of memory, large knuckles, has had knee replacement, gets very confused, and last but not least, had the horrible neck pain, but it never came back after the oral antibiotics. It is the only symptom that the oral antibiotics helped and that was only a two week presciption. Could you please tell me who a Lymes doctor is in Central Florida that really will treat it? Everyone takes the test and says that they didn’t see the rash so they don’t consider he has it. Please, we are in Winter Haven Fl. but will drive.
