HI, thanks for using healthcare magic
Almost anything can cause an
allergic reaction. This is because persons react differently to plants, animals, environmental stimulants (eg dust, pollen, perfume odours), medications, food.
What may provoke a reaction in one person may not do so in another.
Allergic reactions can present in different ways, the most common ways are skin rash, swelling,
post nasal drip of mucus, itching,
difficulty breathing. In the case of foods some persons may have vomiting or diarrhoea,
indigestion.
Excess salivation is not a common presentation of allergies though everyone is different. If you are noting a decrease in symptoms with the use of the medication then it is possible that it was an
allergic response.
It would be difficult , however, to say what you are allergic to.
I hope this helps
