If you are taking sudafed for more than 5 days in a row, please STOP as you will get exactly the opposite symptoms since you started. This is called tachyphylaxis
, meaning you develop tolerance to the chemical quickly and get the worse symptoms.
Antihistamines, nasal sprays for 2 weeks would be worthwhile (antihistamine nasal spray like azelastine
or combined with a steroid
for 6 weeks).
Allergy testing by skin prick tests or specific IgE blood test
will be worthwhile if these symptoms do come in circles or have a seasonal pattern.
