Drug Challenges

There are many medications for which there is no allergy skin test available and no accurate blood test. Your doctor will get a detailed history. In some cases, if the physician feels it is safe, they may recommend a drug challenge.

This involves administering the medication in the allergist’s office in a very small dose and then increasing the dose 2-3 times to reach a normal dose.

This can be the most effective way to determine if you are allergic to a drug or not. It will be up to the physician if they feel this is the right plan for you.

Patient Stories

“My family has been under the care of Dr. Clarke and her wonderful staff for almost 10 years. If you want to feel like family and taken well care of this is the place to go. My allergies and asthma have been better than they ever have with the help of Dr. Clarke and her staff. So, if you have suffered from lifelong allergies and asthma this is the place to go.”
