I take Modafinil. Could it interfere with my rabies vaccine?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am on an anti-rabies vaccination. I am very worried as I have been on other medications which I believe may interfere with rabies vaccine:

1. Modafinil.

2. Fat burner (Ingredients: Yohimbine, Bioperine, Guggulsterones, Synephrine, Caffeine).

Kindly help.

Answered by Dr. R. Rahul

Hello,

Welcome to icliniq.com.

As per your medical history, I would suggest that the above-mentioned medicine will not interfere with the rabies vaccine.

However, keep the rabies vaccine as the top priority and, if possible, stop other medications until the course is done, as rabies is a much more serious disease than fat burners.

Regards.

Patient's Query

Hello doctor,

Thank you for the reply.

I have been off these medicines for 21 days, but I still fear that they may interfere with my vaccination.

Kindly suggest.

Answered by Dr. R. Rahul

Hello,

Welcome back to icliniq.com.

It is good news that you are off for 21 days. I would like to ask you a few questions -

  1. Which vaccine are you taking, and what makes you say it interferes?
  2. Are you experiencing any side effects? Lastly, where was the bite, and was it a stray dog or a pet dog?

Regards.

Patient's Query

Hello doctor,

Thank you for the response.

It was a rabid dog that was killed by an animal doctor. He did not bite me, but a possible exposure since I handled him,and my hands have open wounds.

So I got tensed about the situation and came to know that many medicines interfere with rabies vaccine, and I could not find if Modalert interfered with rabies vaccine or not, also I am taking Abhayrab.

Kindly help.

Answered by Dr. R. Rahul

Hello,

Welcome back to icliniq.com.

Abhayrab is a very good vaccine, and as per your history, there has been no bite, so you come under the low-risk category for rabies.

Medications and vaccines work in totally different ways in our bodies, and you need not worry, as nothing will happen. The only thing is to complete the vaccination course, and everything will be fine. Do not worry.

Take care.
