Plavix allergic reactions can be treated with a combination of antihistamines and steroids, as per a latest study by doctors from the Thomas Jefferson University Hospital.

Plavix, or Clopidogrel, is considered to be one of the most prescribed drugs in the medical world. However, around six percent of this drug’s users complain of allergic reactions. But, the above findings clearly suggest that Plavix allergic reactions would no longer be a cause of concern.

The study was conducted with 24 patients who have shown signs of  Plavix allergies after coronary stent procedures. Twenty-one of twenty-four patients were able to stay with antihistamines and steroids after witnessing Plavix allergies in the past.

From ScienceDaily:

A clinical study of cardiac patients who suffered an allergic reaction to the widely-prescribed drug clopidogrel, also known by the pharmaceutical name Plavix, found that treatment with a combination of steroids and antihistamines can alleviate the allergic reaction symptoms thereby allowing patients to remain on the drug, say doctors from Thomas Jefferson University Hospital. The study followed 24 patients, who developed Plavix allergies after undergoing coronary stent procedures.

Eighty-eight percent (21 of 24) were able to stay on Plavix uninterrupted after being treated with the antihistamines and a short course of steroids. Primary Investigator Michael P. Savage, M.D., director, Cardiac Catheterization Laboratory at Thomas Jefferson University Hospital and Kimberly L. Campbell, M.D., cardiology fellow and lead author, presented their findings at the American College of Cardiology’s Annual Scientific Session on March 30 2009.

“This is a very important study for many cardiac patients but especially those with stents,” said Savage. “Every patient who receives a stent must take Plavix to help prevent stent thrombosis which is clotting of the stent. This obviously poses major problems if the patient suffers an allergic reaction to the medication. To discontinue taking the drug can lead to a heart attack which may be fatal. Those with a drug eluting stent are required to be on the drug for at least one year. Our patients with drug eluting stents actually averaged 17 months on Plavix versus the minimum of one year. That’s a very long time to not be on a medication that may save your life.”

The above findings clearly suggest that a combination of steroids and antihistamines can help patients continue its usage without any allergy symptoms. Such a treatment is also beneficial for all those patients who have received stent by protecting them against stent clotting.

This study by doctors from the Thomas Jefferson University Hospital is the first systematic study demonstrating Plavix allergy management without discontinuation.
