Understanding Allergy and Hay Fever Medications
There are many types of medications available to combat the symptoms of allergies and hay fever. The types of medications include antihistamines (Claritin, Zyrtec), decongestants (Sudafed), anticholinergic nasal sprays (Atrovent), corticosteroid nasal sprays (Flonase, Nasonex), antiallergy eyedrops (Patanol), leukotriene inhibitors (Singulair), and mast cell inhibitors (Nasalcrom). -
Can Migraines Cause Fever and Chills
A migraine headache causes symptoms such as severe head pain and sensitivity to light, sound, or smells. Migraines do not, however, cause a fever or chills. Fever and chills may be red flags of another condition if accompanied by other signs such as night sweats, weight loss, or a sudden "thunderclap" headache. If these symptoms occur, you should see a doctor immediately. -
Can Scarlet Fever Go Away on Its Own
While scarlet fever can go away on its own, the illness can lead to complications including a serious disease called acute rheumatic fever which can damage the heart, so antibiotic treatment is recommended. Scarlet fever is a bacterial infection that causes a red rash and often a sore throat. Scarlet fever is caused by the same bacteria that cause strep throat. -
Can You Have a Fever with Allergies
Allergic reactions do not cause a fever. If you have allergy symptoms and a fever, you may have another condition such as bacterial or viral infection, extreme sunburn, heat exhaustion or heat stroke, or an inflammatory condition such as rheumatoid arthritis. See a doctor if you have allergy symptoms along with fever. Sudden, severe, widespread symptoms due to allergic reaction (anaphylaxis) are potentially life-threatening and require emergency care. -
Hay Fever vs Cold
Hay fever, or allergic rhinitis, is another term for allergies, caused by an immune overreaction to pollen and other allergens in the air. The common cold is an upper respiratory infection caused by a virus that usually affects the nose but may also affect the throat, sinuses, Eustachian tubes, trachea, larynx, and bronchial tubes - but not the lungs. -

A temperature of 99.9° F (in the armpit) would be considered a fever only in babies under one year. A core (rectal) body temperature of 100.4° F (38.0° C) or higher in adults, and 99° F (37.2° C) (armpit) or 100.4° F (38° C) (rectal) in babies under one year is considered a fever. -
Sore Throat

What Is Considered a Real Fever
A fever is a higher-than-normal body temperature. A fever is not an illness in itself, but a sign the body is fighting an infection. Fever is often defined as a core (rectal) body temperature of 100.4° F (38.0° C) or greater in adults and 99°F (37.2°C) (armpit) or 100.4°F (38°C) (rectal) in babies under one year. A fever usually isn't a concern unless it is 103° F (39.4° C) or higher.
