Chronic allergies affect millions of people around the globe, and there’s no denying the discomfort they cause. A 2017 study published in The Journal of Allergy and Clinical Immunology has found that 80 percent of those with seasonal allergies report moderate-to-severe symptoms that significantly impair their quality of life. But although allergies can’t be cured outright, those afflicted can take over-the-counter medications to alleviate some of the symptoms, which may include sneezing, runny nose, coughing and water eyes.

According to Laura Moore, MD, allergist-immunologist at the Allergy, Asthma and Immunology Center of Alaska, allergy medications available today can be broken down into the three main categories: oral antihistamines, nasal steroids, and eye drops.

Individuals who suffer from allergies may take one medication from each category (nasal steroid, eye drop, and oral antihistamine) at the same time, says Dr. Moore. However, you should never double up (i.e. use multiple nasal steroids together). If symptoms persist, it’s best to schedule an appointment with an allergist. You might require prescription treatment options and/or immunotherapy.

But for most people, a regimen of over-the-counter allergy medications can help. Here’s what you need to know.

Oral Antihistamines

According to Moore, oral antihistamines can be good for combatting those common allergy symptoms such as sneezing, itching, and watery/drippy nose and eyes. And fortunately, most people have no issue tolerating these medications. They can be taken daily or as needed. However, before popping a pill, make sure you look carefully to see if it could make you drowsy so you take it at the appropriate times.

Here are the four main long-acting oral antihistamines available over-the-counter:

Claritin 24-Hour Allergy Tablets

Allergies can wreak havoc on your daily life. Sneezing, congestion and a runny nose are just a few of the symptoms that make it tough to get through the day. And while there are plenty of over-the-counter (OTC) allergy medications available, not all are created equal—some can make you feel drowsy or groggy.

That said, there are plenty of allergy medication options available that won’t make you feel sleepy. A variety of forms, including tablets, liquids and nasal sprays are available at a local retailer or online without a prescription.

If you’re looking for a non-drowsy allergy medicine that will still provide relief from your symptoms, there are a few things to keep in mind. Here’s an overview of how non-drowsy allergy medicines work, as well as their potential side effects and expert-backed recommendations.

What Is Non-Drowsy Allergy Medicine?

Non-drowsy allergy medicine is a type of medication that relieves allergy symptoms without making you feel tired. Their chemical makeup is different from traditional antihistamines (a common class of allergy medication), which can cause drowsiness as a side effect.

“Non-drowsy, also known as second-generation antihistamines, are less soluble in lipids and consequently have reduced capability to penetrate the blood-brain barrier,” says William Harris, M.D., an allergist with Providence St. Joseph Hospital in Orange County, California. “Thus, they are less active in the brain, resulting in lower sedation.”

First-generation antihistamines, such as Benadryl (diphenhydramine) or Chlor-Trimeton (chlorpheniramine), often cause drowsiness because they’re more likely to cross the blood-brain barrier. Second-generation antihistamines, such as Claritin (loratadine) or Zyrtec (cetirizine), are less likely to cause drowsiness because they don’t cross the blood-brain barrier as easily.

How Does Non-Drowsy Allergy Medicine Work?

Non-drowsy allergy medicine works by blocking the effects of histamines. Histamines are chemicals that are released in your body when you’re exposed to allergens, such as pollen or pet dander. Blocking the effects of histamines can help relieve the symptoms of allergies.

“All antihistamines work the same,” explains Dr. Harris. “By blocking histamines, they all relieve the symptoms of allergies, including sneezing, runny nose, itchy eyes and congestion.”

When considering trying a non-drowsy allergy medicine, first, take a look at the active ingredients. Second, take note of any possible side effects. And lastly, be sure to read the labels carefully before purchasing.

Types of Non-Drowsy Allergy Medicine

There are a variety of non-drowsy allergy medications available. They come in several forms, including pills, liquids and nasal sprays. Some are available over-the-counter, while others are available by prescription only.

Non-drowsy allergy medications are available as:

  • Pills: Oral pills are the most common type of allergy medication. They’re easy to take and can be taken with or without food.
  • Liquid: Liquid forms of antihistamines are available for both adults and children. They’re usually taken with a measuring spoon or syringe.
  • Nasal spray: Nasal sprays are used to relieve nasal congestion. They’re usually taken once or twice a day.
  • Eye drops: Eye drops are used to relieve itchy, watery eyes. They’re usually used as needed to control symptoms.

Allegra (fexofenadine)

Allegra (fexofenadine) is a fast-acting and non-drowsy antihistamine that works to relieve the symptoms of allergies. It’s available over-the-counter (OTC) without a prescription. For adults, Allegra is available in tablet and gelcap form. Its children’s version is available in liquid and dissolvable tablet form.

Claritin (loratadine)

Another non-drowsy OTC option, Claritin (loratadine) is available in tablet, gelcap, dissolvable tablet, chewable and liquid form.

You shouldn’t take Claritin if you’re allergic to loratadine or any of the other ingredients in Claritin. If you have kidney disease, liver disease or any other medical conditions, talk to your provider before taking Claritin.

Flonase (fluticasone)

For those with more severe allergies, Flonase (fluticasone) is a prescription-strength, non-drowsy nasal spray. It’s now available as an OTC option without the need for a prescription. Flonase works by blocking the release of histamines and can relieve allergy symptoms far beyond nasal congestion, including sneezing, runny nose and watery eyes. This 24-hour spray is a good choice for adults and children ages four and older.

You shouldn’t use Flonase if you’re allergic to fluticasone or any of the other ingredients in Flonase. If you have any medical conditions such as tuberculosis, liver disease or glaucoma, talk to your provider before using Flonase. You also shouldn’t use Flonase if you have an open sore in your nose.

Nasacort (triamcinolone)

Nasacort (triamcinolone) is another prescription-strength, non-drowsy nasal spray option that’s available without a prescription. It works by blocking the release of histamines in the body and can provide relief from nasal congestion, runny nose, itchy nose and sneezing. Nasacort is available as a 24-hour spray and is a good choice for both children and adults.

You shouldn’t use Nasacort if you’re allergic to triamcinolone or any of the other ingredients in Nasacort. Talk to your health care provider before using Nasacort if you have tuberculosis, increased pressure behind the eye (intraocular pressure), have glaucoma or have recently taken corticosteroids.

Xyzal (levocetirizine)

Another 24-hour option, Xyzal (levocetirizine) is an antihistamine that reduces sneezing, scratchy throat, runny nose, itching and watery eyes in adults and children ages six and up.

Zyrtec (cetirizine HCL)

Zyrtec (cetirizine HCL) is an antihistamine that comes in standard capsule, tablet, gelcap, liquid and dissolvable tablet form. It’s available for adults and children at least two years of age and may be taken once or twice daily for indoor and outdoor allergy relief. Age requirements and directions vary by form, so it’s important to read the label of each Zyrtec product carefully before choosing the best option. Children between the age of two and six years old should only take the Children’s Allergy Syrup.

As with any medication, don’t take Zyrtec if you’ve ever had an allergic reaction to cetirizine, hydroxyzine or any other ingredient in the medication. Talk to your health care provider before taking this medication if you have liver, kidney disease or any other health problems.

Risks and Side Effects of Non-Drowsy Allergy Medicines

Like all medications, there are some risks and side effects associated with non-drowsy allergy medicines. Common antihistamine side effects, according to Dr. Harris, include:

  • Dry mouth
  • Headache
  • Drowsiness
  • Indigestion or upset stomach
  • Nervousness

When choosing a non-drowsy allergy medicine, it’s important to weigh the risks and benefits of each option. If you’re not sure which medication is right for you, talk to your health care provider.

Who Should Take Non-Drowsy Allergy Medicine?

Non-drowsy allergy medicine is safe for most people. However, they may not be right for everyone. If you have a history of seizures, kidney disease, liver disease or are pregnant or breastfeeding, talk to your doctor before taking any non-drowsy allergy medicine.

When to See a Doctor

The severity of your allergies and the symptoms you’re experiencing will determine when you need to see a doctor, notes Dr. Harris. If your allergies are mild, over-the-counter medications may be all you need. However, if your allergies are moderate to severe, you may need prescription medication.

Dr. Harris recommends seeing a doctor for your allergy symptoms if:

  • Your symptoms aren’t controlled with OTC allergy medications
  • You experience significant side effects from OTC allergy medications
  • You wish to identify potential allergen triggers in your work or home environment

Your allergy symptoms shouldn’t interfere with your quality of life. If they are, it may be time to see a doctor. There are medications and treatments available that can provide significant relief for your allergy symptoms.

What allergy medicine is best for congestion?

Nasal steroids are a type of nose spray and are often the first drugs recommended for allergies. They're a powerful way to fight stuffiness because they get to the root of the problem..
Beclomethasone (Beconase).
Fluticasone (Flonase).
Mometasone (Nasonex).
Triamcinolone (Nasacort).

What allergy medicine will dry up a runny nose?

An antihistamine is the best medicine for allergy-related runny noses. Antihistamines block histamines, the culprit behind common allergy symptoms such as watery eyes and runny noses. Diphenhydramine and chlorpheniramine are the two most common antihistamines, but they cause drowsiness.

Is Zyrtec or Claritin better for congestion?

Claritin-D and Zyrtec-D are effective for allergy symptoms. With an added decongestant, both medications are effective for treating sinus pressure and nasal congestion. Some studies suggest that Zyrtec is more potent than Claritin. However, Zyrtec may have more sedative effects than Claritin.

Which is better for a runny nose antihistamine or decongestant?

Which one should you take? For true cold symptoms, a decongestant will provide more relief than an antihistamine. If you notice your “cold” symptoms occur at the same time each year (spring for examine), or are consistent year-round, you may actually have allergies that could benefit from antihistamine medication.
