With spring allergies in full swing and summer allergies on the way, many turn to over-the-counter (OTC) medications for relief. Antihistamine use, however, often comes with undesired side effects such as drowsiness, loss of libido, increased appetite, and depression. Additionally, recent studies suggest that common allergy drugs with antihistamines may have more severe impacts on health, creating additional risks for allergy sufferers. I can help with options for allergy relief when OTC medications raise concerns.

Caution with antihistamines

Researchers at the University of Oregon discovered that muscle recovery and muscle gain after exercise may be blunted by over the counter drugs commonly used for allergy and acid reflux. After rigorous exercise, thousands of genes activate to help the body recover. But with elevated antihistamine levels, nearly 30 percent of genes don’t respond as effectively.
It turns out that histamine, the bodily substance most often associated with allergy symptoms, is also important for helping blood vessels relax, increasing blood flow, and ensuring the body recovers. Antihistamines, therefore, could create problems for those who exercise often or competitively.

Antihistamines have also been identified as problematic for people with restless legs syndrome, a condition that affects nearly 12 million people in the US. OTC medications such as Benadryl, taken to relieve allergies, or sleeping pills with antihistamines, can make the symptoms worse. This creates added difficulties during allergy season and the need for alternatives for sleep aid and allergy relief.

Another recent study from the University of Washington’s School of Pharmacy links diphenhydramine use (common for allergy relief) to increased rates of dementia. Tracking 3,500 men and women over the age of 65 for an average of seven years, the study found that the use of anticholinergic drugs, including some antihistamines and antidepressants, resulted in an increase risk for dementia. Findings indicated that, “Taking an anticholinergic for the equivalent of three years or more was associated with a 54% higher dementia risk than taking the same dose for three months or less.” This finding adds to a growing body of research that says these drugs are not intended for long-term use.

Alternatives to antihistamines

Patients seeking alternatives to antihistamines for allergy relief have options at Heart Spring Health. I offer comprehensive allergy evaluation and testing followed by allergy treatment with a customized prescription of allergy drops tailored to address your specific allergic reactions. Also known as sublingual immunotherapy (SLIT), allergy drops are noninvasive, cost-effective, and convenient. No shots or antihistamines are necessary, and SLIT therapy is effective for people of all ages.

Over time, use of SLIT results in a decreased sensitivity to your allergens, decreased symptom severity, and decreased medication use when exposed to the allergens in the environment to which you are sensitive. SLIT works in a similar way to allergy shots, uses the same FDA-approved antigens, and is recognized internationally as safe and effective. By taking drops under the tongue, they are also easier to administer and result in fewer office visits.

If you are new to allergy drops, here’s how your treatment would begin:

1. Initiate a comprehensive allergy evaluation to assess symptoms and exposures
2. Complete allergy testing with skin prick or blood tests
3. Begin using your customized prescription of liquid allergy drops, taken under the tongue
4. Plan for long-term use for maximum relief (2-5 years)
