I use afrin nose spray sometimes to relieve nose congestion. I know that it should not be used more than 4-7 days continuously so I respect the recommendation. It seems to me that afrin causes me stomach upset, nausea and sometimes dizziness. Is it possible that these symptoms are due to afrin?
It is possible and not rare to happen. Afrin may cause mild stomach upset, headache, dizziness, nervousness or even trouble sleeping. It is recommended to take plenty of water or other fluids while on afrin. I also have allergy problems very often and use afrin spray to relieve them, so am familiar with these adverse effects.
