<s>[INST] Hello and good day....I recently 1 week now have welcomed a puppy into our home and although I know that some breeds are better for allergies I have a mixed breed but the symptoms are unbearable.....which antihistamine would be safer than others to relieve my classic symptoms and is there anything else I can do to live with my pet and not get serious future problems with my health due to antihistamines daily.Also I am confused...do I look for loratadine or desloratadine tablets...help plsRegards, linda [/INST] Thanks for your query.Brief answer: Yes,you can take any of the antihistamines(Loratadine/desloratadine/fexofenadine ) to relief your current symptoms of allergy.Detailed answer:I understand that you are very much affectionate towards your puppy.You are talented enough that you have found out the cause of your allergy. Many allergens are found in animals’ hair, saliva, urine, stool and shed skin.The best treatment for allergy is to avoid allergen or its source if possible.If your allergy is due to puppy, I would request you to keep a distance from it. Otherwise it may create other health problems like asthma in future. Antihistamine is useful to relief symptoms but long term use of a medicine is hardly rational.Hope this answers your query.Wish you good health. </s>
