Medication query. Proper answer sir pls!

Hlo doctor,I was diagnosed for having cholinergic urticaria by my doctor and he prescribed me some medications and shampoo + Lotion but these tablets( Tenzine and Dazit for 2 weeks ) have some adverse side effects which i read from google is it safe for me to have this for 2 weeks bcoz i am scared it's side-effects may cause some other problems in my body or my body may get weaker just for removing symptoms of urticaria .I want to get an answer according to you is it safe for me to consume these tablets with adverse side effects for 2 weeks,is it sure that urticaria will go after that or it may become habitual like you consume hives go and you miss one does it happens again . I want to know a proper answer sir pls Thankyou so much .
