Cedar fever is a common affliction in Texas, especially when the colder months arrive. While cedar fever is not a contagious disease, its symptoms can be very uncomfortable and even debilitating for allergy sufferers.

Fortunately, there are a few ways to manage fever and find relief during the season. Urgent care clinics like City Doc also provide allergy testing and urgent care services for common non-life-threatening allergy symptoms.

Cedar Fever Season in Texas

In Texas, the mountain cedar tree (Juniperus ashei) sheds its pollen during the months leading up to winter, and this can lead to an increase in cedar fever cases — hence, the term cedar allergy season.

The months of December up to February are typically the peak of cedar allergy season in Texas, with cases extending up to March. As such, cedar fever is considered a seasonal allergy.

As with most seasonal allergies, however, fever can also occur during other times of the year. The levels of cedar pollen in the air may reach peak levels at different times than usual due to changes in weather or other factors.

What Is Cedar Fever?

Cedar fever, sometimes called hay fever, is a seasonal allergic reaction to pollen.

The term comes from the cedar mountain tree that is populous in Central Texas, but the allergy symptoms can be caused by any pollen-producing plant such as tree nuts and flowering plants.

When cedar pollen or allergens are breathed in, it can trigger an allergic reaction such as sneezing and watery eyes.

Hay fever is a similar condition but is often caused by grass, weeds, and dust mites.

Cedar fever is often confused with allergic rhinitis, but the two are actually quite different. Allergic rhinitis is a general term for any type of pollen-based allergy, and cedar fever specifically refers to the allergic reaction caused by the pollen from cedar trees in Texas.

What Are the Common Symptoms of Cedar Fever Allergy?

Mild symptoms of cedar fever include:

  • Itchy, watery eyes
  • Nasal congestion
  • Runny nose and sinus pressure
  • Sneezing
  • Sore throat
  • Fatigue
  • Low-grade fever

In some cases, cedar allergy can cause asthma and other respiratory issues such as a sinus infection.

However, emergency medical attention is needed if you notice the following symptoms of a severe allergic reaction:

  • Anaphylactic shock: Swelling of lips, eyes, and throat; difficulty breathing; dizziness; low blood pressure; rapid pulse
  • Chest tightness
  • Vomiting and/or diarrhea
  • Swelling in the throat and other areas

Causes of Cedar Fever

Cedar fever, in particular, is caused by the immune system’s allergic reaction to the pollen of mountain cedar trees. To a healthy immune system, mountain cedar pollen is harmless, but to an allergy-prone one, exposure can quickly become problematic.

The symptoms of fever can be exacerbated by other common allergy triggers such as:

  • Pet dander
  • Mold spores
  • Dust mites
  • Pollen from other plants and trees
  • Air pollution
  • Smoke, strong odors
  • Food allergies (in some cases)

How to Treat Texas Cedar Fever

Allergy Medications

Common allergic symptoms can be easily treated with over-the-counter medications such as:

  • antihistamines
  • decongestants
  • nasal sprays

For more severe allergic reactions, your doctor may prescribe stronger medications such as:

  • steroid nasal sprays
  • leukotriene modifiers

Allergy shots or drops (immunotherapy) are another option to reduce the sensitivity to cedar pollen and other allergens, but they should be discussed with an allergy specialist first.

Our allergy specialists at City Doc Urgent Care are happy to help you with your cedar fever symptoms and provide a treatment plan that works best for you.

Allergy Avoidance 

Avoiding outdoor activities during peak pollen times is one of the best ways to prevent fever.

Depending on your medical history, it’s also important to avoid other triggers that have caused your past allergic reactions. Generally, it’s advised to keep dust mites and pet dander in your home at a minimum by frequently cleaning, keeping windows closed, and using an air purifier.

Tips to Know When Preparing for Cedar Fever Season in Texas

If you are prone to allergies and live in Central Texas, preparation is key during the peak months of fever season. Here are some tips to help you:

1. Limit outdoor activities

Pollen levels tend to be highest from mid-December through mid-February. Consider staying home as much as possible during this time. Having an air purifier at home can also help reduce allergens.

2. Wear a mask outside

Wearing a face mask can help filter out the cedar pollen. Make sure to wear a mask rated for pollen allergens if you must go outside. If you also suffer from asthma, talk to your doctor about an appropriate mask for you.

3. Keep windows closed

Keeping your windows shut can help prevent cedar pollen from entering your home, so make sure to open them only when absolutely necessary. The same goes for driving in your car.

4. Change your clothes and wash off before coming inside

If you have been outside, make sure to change your clothes and take a shower before entering the house. This will help prevent any pollen from lingering and entering the home.

5. Check pollen levels before going outside

If you can, check your local weather and allergy forecasts so you know what to expect in terms of pollen levels. Some of the things you should watch out for are high humidity, windy conditions, and the presence of other allergens such as mold.
