Migraines and Headaches: Sinus Headaches

Sinuses are air-filled cavities (spaces) located in your forehead, cheekbones, and behind the bridge of your nose. The sinuses produce a thin mucus that drains out of the channels of the nose. When a sinus becomes inflamed, usually as the result of an allergic reaction, a tumor, or an infection, the inflammation will prevent the outflow of mucus and cause a pain similar to that of a headache.

What Are the Symptoms of Sinus Headaches?

Sinus headaches are associated with a deep and constant pain in the cheekbones, forehead or bridge of the nose. The pain usually intensifies with sudden head movement or straining. The pain is usually accompanied by other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, and facial swelling.

Sinuses

Whether your headache symptoms can actually be attributed to the sinuses will need to be determined by your doctor. If your headache is truly caused by a sinus blockage, such as an infection, you will likely have a fever. CT scans or MRI along with a physical examination are usually conducted to determine if there is a blockage in your sinuses.

How Are Sinus Headaches Treated?

Treatment of sinus headaches is usually directed toward symptom relief and treating the infection. Treatment might include antibiotics for the infection, as well as a short period of antihistamines (such as Benadryl) or decongestants (such as Sudafed) to treat the symptoms. If you take decongestants, but do not have a true sinus headache, the medication could make your headache worse. Be sure to see your doctor before taking any medications.

Other medications to treat sinus infections include pain-relievers and vasoconstrictors (to decrease nasal congestion). If the pain continues after using pain-relievers, corticosteroids may be prescribed to further decrease the inflammation. When an allergen is causing the sinus flare-ups, preventive allergy therapy is often needed.

Decongestant medications can be used to relieve headaches associated with sinus infections. Decongestants help relieve headache symptoms because they constrict blood vessels that cause headache pain. However, decongestant use can be habit-forming. If your headaches seem to be relieved by decongestants but you do not have a sinus infection, you may actually have a migraine or tension headache, which require specific treatment.

Can Allergies Cause Headaches?

It is a misconception that allergies cause headaches. However, allergies can cause sinus congestion, which can lead to headache pain. If you have allergies, the treatment for your allergy will not relieve your headache pain. The two conditions generally must be treated separately. See your doctor to ensure proper treatment.

TOPAMAX is approved for migraine prevention in adults only.
TOPAMAX is not used to stop a migraine after it starts.

IMPORTANT SAFETY INFORMATION

Serious risks associated with TOPAMAX include lowered bicarbonate levels in the blood resulting in an increase in the acidity of the blood (metabolic acidosis). Symptoms could include hyperventilation (rapid, deep breathing), tiredness, loss of appetite, irregular heartbeat or changes in the level of alertness. Call your doctor immediately if you get these symptoms. Your doctor may want to do simple blood tests. Chronic, untreated metabolic acidosis may increase the risk for kidney stones or bone disease.

Other serious risks include decreased sweating, increased body temperature, kidney stones, sleepiness, dizziness, confusion, difficulty concentrating, and increased eye pressure (glaucoma). Call your doctor immediately if you have any decrease in vision or eye pain. These problems can lead to blindness if not treated right away.

More common side effects are tingling in arms and legs, loss of appetite, tiredness, nausea, diarrhea, taste change and weight loss.

Tell your doctor about other medications you take. Please see full U.S. Prescribing Information.
