Brief Answer:
Nasal sprays r extremely safe, if problem, see doc
Detailed Answer:
Hi, thanks for asking.
The nasal sprays are one of the safest way of treating
nasal allergy. There are very few side effects which be further minimized by intermittently breaking their use for few days but even a continuous use is perfectly safe. Common side effects are - Irritation in nose,
nausea,
vomiting, coughing. Another side effect on long term use reported is
fungal infection in nose and throat but this is very rare and can be minimized by intermittent use. Always start a new drug after consulting a specialist doctor of that field and same is true for this drug also. In case symptoms like fever, rash, severe throat pain or whitish patches in oral cavity, do consult your doctor. Another misconception is that once you start using these, you will always need these - is a misconception.
Regarding
homeopathy, its not my expertise, thus I will not be able to comment on it.
Take care.
