Can allergies cause fever and chills?

You can try drinking warm ginger tea or taking steam to feel comfortable. But fever and chills usually mean a viral illness, not just allergies, so please consult a doctor if your temperature is high.

No, typical allergies do not cause fever and chills. You should see a doctor as it is likely an infection.

I just recovered from this last week; I thought it was my usual dust allergy, but it turned out to be a sinus infection. The fever and chills were a clear sign of infection, and taking antibiotics prescribed by my doctor cleared it up.

Fever and chills suggest your immune system is battling an infection rather than an allergy. Keep your diet light with warm vegetable soups or dal khichdi, and avoid cold foods while you wait to see a doctor.

I agree with others, allergies rarely cause actual fever. Please consult a doctor to check for a cold or flu.

My family physician explained that allergies can block sinus drainage, which can sometimes lead to a secondary bacterial sinus infection. That secondary infection is what actually causes the fever and chills, so you should have a doctor examine you.
