Question

PHARMACOLOGY

Because "Mrs. Norris" the cat is aggravating his allergies and the oral antihistamines haven't been working as well, Mr. Hagrid has also been using a nasal decongestant spray several times daily for the past few weeks. He tells you the nasal spray does not seem to be helping anymore, even though he has increased the amount of sprays he is using. Mr. Hagrid is desperately looking to you for a solution to his allergy problem or he says that, "as for that cat, 'Mrs. Norris, I'd like to introduce her to my dog Fang sometime" 3. How do you explain the reaction Mr. Hagrid is having to the nasal spray? 4. Would you expect Mr. Hagrid to be able to continue to use the nasal spray without interruption? Why or why not?

Answer 1

3. Mr. Hagrid might have Rhinitis Medicamentosa, a condition that occurs due to over usage of decongestant nasal sprays. The chemicals in the nasal sprays helps in opening up the blocked areas by shrinking the congested blood vessels.Over usage of these sprays causes the blood vessels not to respond,leaving allergic reaction the same.

4. Mr. Hagrid should continue using it for few days without stopping at once. The nasal decongestant spray cannot be stopped at once,as it can cause more irritation and swelling.So the use should only be reduced gradually and when it is stopped completely,an alternative solution can be done.
