Reason #: Botched Diagnosis
Getting a correct diagnosis also plays a big role in keeping allergy symptoms at bay.
Patients often try to self-diagnose when it comes to things like allergies and sinus headaches, but they don’t always get it right. Maybe you’re sure it’s an allergy, and it’s not. Or maybe you think you’ve got a sinus infection, but you really have an allergy.
If your diagnosis is wrong, your treatment may be all wrong. For instance, if you actually have a tension headache, using an antihistamine won’t improve the situation, says Corinna Bowser, MD, an allergist in Narberth, Pa.
The fix: If you have allergic symptoms or suspect you have an allergy, consult a doctor to find out if it really is an allergy.

How Do I Know Whether I Have Seasonal Or Perennial Allergic Rhinitis
Symptoms for both seasonal and perennial allergic rhinitis are generally the same â nasal congestion, runny nose, itching, sneezing, and sometimes watery and itchy eyes. However, symptoms for seasonal allergic rhinitis generally appear according to the season commonly associated with the particular allergy you have. For example, if you have an allergy to tree pollen, your symptoms would usually appear in the spring.
Perennial allergic rhinitis symptoms occur as a result of allergens that you are exposed to year-round, such as dust mites and animal dander. For a diagnosis of whether you have seasonal or perennial allergic rhinitis , you should make an appointment with your doctor.
What About Allergy Shots
Out of an abundance of caution, you should avoid getting any routine allergy shots on the same day as your COVID-19 vaccination, says Abinash Virk, M.D., an infectious disease expert at the Mayo Clinic.
The reason: There isnt enough research to determine whether getting the vaccine on the same day as an allergy shot is safe and effective, since any injection has the possibility, however faint, of messing with your bodys immune response. In this case, its just best to err on the side of caution. The recommended wait is similar to how we separate vaccines from the COVID-19 vaccine by 14 days, notes Dr. Virk. We recommend 48-hour separation from allergy shots to decrease the risk of adverse effects from the vaccine.
Experts at Penn Medicine, meanwhile, recommend separating shots by at least one full week. Ultimately, the decision will be up to you and your doctor, who knows your medical history and can take a personalized approach to your needs.
The same goes for prescription steroid medications for allergies, like Depo-Medrol and Kenalog, which have the potential to meddle with your immune systems reaction to the COVID-19 vaccines, Dr. Parikh says.

When You Take Allergy Medicine Every Day This Is What Happens
Spring is a great time of year. The weather gets warmer, the days get longer, but if you’re prone to allergies, the increased dust, pollen, and everything in between can make the season unbearable.;
Antihistamines, or allergy medicines, are used to control how much histamine, a chemical made by the immune system in response to allergens, the body produces. But like a lot of medications, allergy pills come with side effects, which can include drowsiness, dry mouth, weight gain, an increased heart rate, headaches, a sore throat, and nausea.;
There can also be rare side effects when a person abruptly stops taking allergy pills after regular use. According to Sandra Lin, MD, a professor and the vice director of Otolaryngology-Head & Neck Surgery at John Hopkins School of Medicine, halting pill usage can result in itchy skin and disrupted sleep .
But what happens when someone takes medicine for allergies every single day for an extended period of time? Is that okay? Is it harmful? After all, 50 million Americans must put up with an array of allergens each year .
Skip Having A Drink With Dinner
Drinking any type of alcohol increases blood flow to the linings of your nose and can make nasal allergy symptoms worse, notes Dykewicz. Also, if youre someone who has year-round nasal issues, including frequent congestion, this scenario can be complicated by alcohol. When seasonal allergies hit and youre already feeling congested, skip the beer or wine to avoid worsening your allergy symptoms.

What Are Antihistamines
Antihistamines are a class of drugs used to control the bodys production of histamine, a chemical made by your immune system in response to common allergens like mold, dust, pollen, ragweed, pets, insect bites/stings, latex, and food. The release of too much histamine spurs bothersome symptoms like itchy eyes, coughing, sneezing, runny nose, congestion, itchy throat, itchy skin, rashes, wheezing, shortness of breath, nausea, vomiting, insomnia, and fatigue.
Antihistamines are classified into two groups:;
Seasonal allergies are typically limited to the spring, summer, and early fall, but perennial allergies can occur year-round. If its not possible to eliminate exposure to your allergy trigger, you may keep daily symptoms under control with an antihistamine.
How To Take It
Adults and children 6 years and older can take cetirizine capsules and tablets.
The usual dosage for adults younger than 65 years and children who are 6 years and older is one 10-milligram dose per day.
You shouldnt take more than 10 mg in 24 hours. Your doctor may recommend a 5-mg dose once or twice per day if your allergies are mild.
Talk to your doctor about dosage for people who:
- are 2 to 6 years old
- are older than 65 years
- have liver or kidney disease
Cetirizine is a newer, second-generation antihistamine. Unlike first-generation antihistamines, cetirizine is less likely to cause side effects such as dangerous drowsiness, dry mouth, blurred vision, and overheating.
That said, Cetirizine can cause adverse effects, such as:
- some drowsiness
- diarrhea
- vomiting
Tell your doctor about any unexpected side effects that you have while taking cetirizine. Also, discuss any ongoing or bothersome side effects. These side effects are usually not emergencies.
Following are a few things to consider before taking cetirizine.

What Happens If I Miss A Dose
Since cold or allergy medicine is taken as needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
Shower Immediately After Being Outside
When you spend a lot of time outside, particularly if youre working out in the yard, pollen can end up on your skin and hair, worsening;allergy;symptoms. If youre highly allergic to pollen, its a good idea to take a second shower after you come inside to rinse away the pollen and avoid allergy symptoms, explains Mark S. Dykewicz, MD, a professor of internal medicine and the director of allergy and immunology at the Wake Forest University School of Medicine in Winston-Salem, North Carolina.

Comparing Claritin Zyrtec And Allegra
Claritin, Zyrtec, and Allegra are all considered newer generation antihistamines. First-generation antihistamines, such as Benadryl and Atarax , can be helpful for allergies and hives as well, but their use is limited due to side effects such as fatigue and sedation .
So while Claritin, Zyrtec, and Allegra are all newer generation antihistamines that can treat hay fever or hives, there may be some advantages for each of these over the others.
What Can You Do If Your Allergy Medication Is Not Working
Allergy shots, also known as immunotherapy, may eliminate or lessen allergy symptoms if medications are ineffective or intolerable. Immunotherapy works by reducing sensitivity to allergens. Each shot contains a small, but increasing, amount of allergen. This challenges the body to build up tolerance over time. The drawbacks to immunotherapy include use of shots, cost and the fact it may take many months to complete.

Talking With Your Doctor
The best antihistamine choice for any one person is based on the degree of symptom relief desired and the degree of side effects you’re willing to tolerate.
For mild to moderate allergy symptoms, Allegra may be preferable to drugs such as Zyrtec since these other drugs are more sedating. Yet for severe symptoms that are interfering with work, school, or play, a medication such as Zyrtec may be needed.
Note that every person is different. This means that despite what studies say, there are many people who do not experience any fatigue on Zyrtec or Xyzal. Likewise, there are people who;do;experience fatigue on Allegra.
It’s sometimes helpful to try different medications to see which works best for you as an individual. If you try this, though, talk with your doctor first.
You might keep a journal to get an objective measure of which drug works best. For instance, you can write down your most annoying symptoms, and rank them from 1 to 10 based on how well they are controlled by different medications.
Talk with an allergist about the possibility of;allergy testing;and;allergy shots. While allergy shots require more follow-up they can sometimes cure allergies so that medications are no longer needed. In addition, it’s thought that allergy shots may sometimes help prevent the development of new allergies.
Can Allergy Medications Harm Your Brain
It’s allergy season and many of us will be reaching into the medicine cabinet for relief. But it is important to choose wisely, as some allergy medications can harm brain health and increase dementia risk.
Diphenhydramine is a first-generation antihistamine medication . In addition to treating allergy and cold symptoms such as sneezing and watery eyes, it also blocks the actions of acetylcholine. This is a neurotransmitter that is important for brain functions including learning and memory. Diphenhydramine is classified as an anticholinergic drug, and a study of this class of drug found that increased use is associated with an up to 54% increased risk of dementia .
SAFER ALTERNATIVES
The good news is that newer antihistamines equal the effectiveness of diphenhydramine with few or no cognitive side effects. These medications were developed to minimize adverse events common to diphenhydramine and other older antihistamines .
If you’re older or have concerns about brain health, consider an allergy medication other than diphenhydramine. In addition to the medications above, topical nasal sprays and allergy shots are available by prescription and can also help alleviate symptoms. As always, it’s a good idea to discuss your options with a medical professional.

Effectiveness And Speed Of Relief
Besides dosing, there are some slight differences in how quickly or well the drugs work.;For example, while Claritin is effective for treating hay fever and hives, other antihistamines, such as;Zyrtec and;Allegra, work better and faster and last longer.
Zyrtec and Allegra work quickly for the treatment of allergic rhinitis and hives, typically within less than an hour. On the other hand, studies show that Claritin takes many hours to start working.
Studies show that Allegra is nearly as good as;Zyrtec;at treating hayfever. However, Zyrtec and its isomer Xyzal appear to be better medicines for the;treatment of hives.
There are also some unexpected nuances associated with each of the antihistamines. For example, if you’re taking Allegra, it’s important to avoid drinking fruit juice for one to two hours before you take the medication and one to two hours after. Juices such as orange juice or grapefruit juice;can decrease the absorption of Allegra;by nearly half.
