My Allergy Symptoms were Horrible too!

When I was in school, I was known as the boy that had severe allergies and I think that everybody felt bad for me. Every day, I would try to blow my nose in class but nothing came out despite how hard I blew because my nasal congestion was so bad. I couldn’t hide my severe sinus congestion, excessive and constant sneezing, nasal drip, and sinus headaches and they were unbearable.

This was a point in my life where I was ignorant about allergy treatment options, whether it be from natural or medical sources. I am not sure why I didn’t try to solve my annoying problem, but I guess that I was just a lazy teenager. But finally, I started getting the motivation to seek allergy treatment because my family members, doctor, and the media had suggested that I pop pills and snort liquids to deal with my problems.

Throughout my life now, I have probably tried almost every OTC allergy drug, as well as a few prescriptions, from Benadryl, Claritin, Zyrtec, Allegra, to Xyzal. I could probably go on a list all the stuff that didn’t genuinely work for me or treat my allergy problem effectively, but Allegra was one of the more efficient drug treatments that really helped my allergy symptoms for the short term.

I am not taking Allegra anymore because I have learned that our unique individual health is complex and takes time to understand and take advantage of. The best allergy treatment for me was a change in lifestyle and tweaking my diet to supplement my unique nutritional needs, as well as using gentle, natural alternatives to harsh drugs that can affect your body in adverse ways.

If you started taking Allegra or another Fexofenadine generic brand or are considering trying it, let me share some useful information that I’ve learned about it from a seasoned allergy sufferer (me) to help you out.

How Does Allegra Work for Allergies?

Fexofenadine is a compound that works as an antihistamine in our bodies. It basically reacts with histamine, a pro-inflammation chemical produced in response to the exposure of our bodies to allergens, and eliminates it from the body. This effectively soothes the direct cause of inflammation in our bodies for the short term.

Histamine is produced by our body’s immune system as a way to promote inflammation. You hear about inflammation all the time as being a bad thing to have, but this mechanism has a biological purpose.

When there is a deadly disease in your body, your immune system tries to kill it and eliminate it so you can survive. Therefore, it produces inflammation around the disease to try to squeeze it and kill it. However, your body puts deadly diseases on the same level as harmless pollen that you are allergic to for some reason.

Your body treats allergens like it’s a pathogen going to kill you. Basically, Fexofenadine and other antihistamines like it, simply stop your own body from producing unnecessary inflammation that could have adverse effects on other aspects of your health.

Allegra is a more recently researched and developed drug that is much newer than the first-generation antihistamines like Benadryl or Diphenhydramine. Fexofenadine boasts that it is a third-generation antihistamine that focuses on increased allergy relief efficiency for a longer duration with less harmful side effects like drowsiness. However, Allegra still gives you the potential for uncomfortable side effects that may make it not worth taking it for some individuals.

This study proves that real Allegra is twice as effective than a placebo. It does something for allergies.

Proper Fexofenadine Dose by Weight and Age

This unique compound has many different uses in the body that have been backed by scientific studies and research. Along with being able to soothe allergy symptoms from hay fever, it is also used for treatment of allergic rash or “chronic idiopathic urticaria.” But we are talking about using it for allergies here, obviously.

For children ages 11 and younger, medical professionals recommend that you supplement a child with a 30 milligram dose of Allegra without the consumption of fruit juice.

For everyone ages 12 and older, the recommended dosage starts at 60 milligrams and ends at 180 milligrams depending on what your unique allergy problem is and what your doctor says. I would say that 60 milligrams was more than enough for me anyway.

Check out my source on that.

I should add that it is highly recommended that you don’t consume fruit juice, especially grapefruit or other citrus while taking your allergy supplement with Fexofenadine because it can interact with the effectiveness of the drug. It can pretty much make it useless and do nothing if you drink fruit juice with it. Strange.

Is Fexofenadine Addictive and Will it Cause Withdrawal Symptoms?

The simple answer is: Yes, Allegra can cause a physical dependency that will make your body rely on its supplementation every day. With chronic long-term use, it is very likely that you will experience withdrawal symptoms after you stop taking it cold turkey.

Antihistamines like these have such a big impact on your health in many different ways that we do not recognize or consider. There’s evidence that suggests that your body starts to work around the supplementation of Allegra and once it is gone, your immune system will not know how to react.

When you are supplementing with Fexofenadine, you are completely masking the symptoms of histamine. Since the root cause of the problem still exists (you still being allergic to whatever it is you were reacting to) your body will slowly start to increase its levels of histamine to make up for its inefficiency.

Your body still sees a harmless allergen as a deadly invader and your immune system is like “What the hell? Why isn’t the histamine working? Let’s make more to get rid of this invader,” so higher levels of histamine and other allergy chemicals will be released. However, you won’t notice because you are in a constant Allegra haze and the histamine doesn’t have a chance to work because it is quickly eliminated. One the drug is gone, you will feel the full effects of your body’s confusion until it adapts over time and stabilizes itself like it always tries to do.

This is what causes withdrawal symptoms, just like what would happen if you were addicted to a stimulant drug that gives us feelings of pleasure. Your body just gets used to something constantly supplementing its natural chemicals so it stops adapting properly itself. Once the drug is gone, your body will start to realize that it needs to adapt so that you can have a harmonious state of health.

Check out more that I wrote about the long-term effects of antihistamines on our health in a more in-depth post.

But the Internet Says that Allegra isn’t Addictive!

Don’t let the internet fool you if you search the question “Can Allegra allergy treatment cause a physical dependence or addiction?” because you will likely get biased results that are trying to get you to buy something. In fact, when you search that, the literal Allegra website comes up. Are they going to tell you the truth that their chemical drug has implications? No, they want you to buy more of their shit and for you to not be afraid of it. A negative connotation to a product or skepticism about it makes you lose customers and they know this.

Of course they are going to tell you that “Allegra is not habit-forming and can safely be used on a daily basis” because they want your money and don’t really care about your health or funding research about the long-term effects of taking it. The truth will always set us free no matter what and that is my opinion. We need to be more skeptical about what is told to us because money will always be a possible ulterior motive that we should consider before making decisions, especially regarding our and our children’s health.

Review for Fexofenadine allergy allegra vs zyrtec vs claritin



Allegra (Fexofenadine) vs Xyzal (Levocetirizine) vs Zyrtec (Cetirizine) vs Claritin (Loratadine) vs Benadryl (Diphenhydramine)

Again, if you search on the internet for an accurate and honest comparison of these antihistamine tablets, then you will likely get a biased, inefficient answer that tries to make you buy something. Thankfully, I have extensive experience with all of these drugs and can give you a reasonable comparison.

Claritin or Loratadine is simply the most ineffective antihistamine I have ever tried. I remember trying this one first, taking it, and noticing no difference whatsoever. Then, I took triple the recommended dose and it made me feel very weird. This is a first-generation antihistamine so you probably shouldn’t expect anything more. I don’t recommend that you buy or take any of the first-generation antihistamines because they suck and they are potentially dangerous to your mental health.

Benadryl or Diphenhydramine is another first-generation drug that I don’t recommend even harder than Loratadine. There is extensive research that was released twenty years late that links the chronic use of Benadryl for allergies and insomnia to dementia and Alzheimer’s disease. It will get rid of your allergy symptoms for a few hours, but it will knock you out cold and make you stupid. I remember the cool kids in high school would take half a pack of Diphenhydramine to get high and I am afraid of the potential risks for their future mental health because of that.

Zyrtec or Cetirizine is a second-generation antihistamine for allergies that I also do not recommend. Although it is more effective at relieving your allergies faster and for a longer period of time, it is often criticized for its huge risk for addiction. So many adults and children are becoming physically dependent on Zyrtec due to its huge effect on the body. Many of you are struggling with this killer addiction to cetirizine and have stumbled upon this site in search of natural solutions for this problem.

Please try to not let yourself or your children become addicted to drugs like these. Some with severe allergies even check themselves into rehabilitation services after trying to stop taking Zyrtec cold turkey.

Xyzal, also known as Levocetirizine, is a third-generation antihistamine that is derived from the same chemical compound as Zyrtec. Notice how it simply has “Levo” added to “Cetirizine” because it is the racemic left enantiomer of Zyrtec. This means that the direction that the chemical compound is facing makes a huge difference in how long it will last in your system. Chemistry is complicated. 

This new drug Xyzal just recently got approved for OTC purchases without the need for a prescription. After trying it, it seems extremely effective in relieving my allergy symptoms quickly. However, I am very skeptical about the long-term effects that weren’t extensively studied yet. I haven’t taken it enough to experience any addictive potential or any side effects, but it made a very strong and clear difference that kind of scared me. I felt like I was crashing at the end of the day when I took it in the morning.

I made a post all about Xyzal or Levocetirizine OTC for allergies here you can check out. Let me know in a comment if you have tried this new OTC drug!

Natural and Gentle Alternatives to Antihistamine Drugs

I don’t rely on antihistamines anymore because of the long-term drawbacks it had on my health. I was becoming extremely addicted to them and the side effects were very annoying and not worth taking it in the first place. The withdrawal symptoms I had experienced after stopping with these drugs for my seasonal allergies were unbearable and made me crave the drugs again to relieve the pain from my reemerged allergy symptoms.

Also, it just seems like the effectiveness of them subsides over time. At first, they are awesome and they do the job, but eventually, they just return you to the state you were at before you were taking them with mild to moderate allergy symptoms.

So what really works for allergies and excess histamine then? That is what my site is all about: figuring out what is causing your allergies in your unique health and lifestyle and then treating these factors accordingly.

Unfortunately, there’s no single answer for why you have these annoying allergies because everybody is different due to genetics, diet, exercise, and the decisions you make in your lifestyle. Everything you do affects other aspects of your health and it’s probably very ignorant to deny that without respect to your future health and well-being.

Personally, I have found that my severe allergies to all the seasons and many different foods, including food intolerances and environmental sensitivities (that have gone away now) were due to poor personal lifestyle choices that I did not realize. Some unnoticeable conditions that were affecting my allergies included organic sulfur deficiency and malnourishment from essential minerals (which is becoming very common for young people) and common intestinal parasites in humans that worsen allergies.

After supplementing with a cheap organic and bioavailable form of sulfur, which is becoming scarce in our inorganic soils due to overpopulation, and doing a natural parasite cleanse, my allergies have improved tremendously. Some of my allergies don’t even exist anymore, I would say, like my legume intolerance, gustatory rhinitis, and histamine intolerance.

From time to time, I still experience harsh allergy symptoms during peak pollen days and I will resort to taking an antihistamine like Fexofenadine for quick and effective results so that I can get through my day easily. However, I want to reject potentially addictive and harmful drugs that can affect my health adversely, like these OTC antihistamine drugs.

What genuinely works during the allergy seasons for me is a natural and gentle nasal spray for allergies and making use of a nasal irrigation tool like a neti pot to relieve the physical causes of allergy symptoms that sets your immune system off. These, among many other things, have helped me treat my allergies naturally to the point where they don’t bother me at all throughout my busy productive day and I don’t even need drugs to mask the symptoms.

Fexofenadine HCl Allegra Allergy Review Questions

Should you take Allegra in the morning or night?

Professionals recommend that you take Allegra before you go to sleep to avoid the potential side effects of drowsiness throughout the day. This makes a lot of sense to me, but I have found that the benefits of taking it slightly wear off after I wake up in the morning. I like to take antihistamines in the morning because they just work better for me that way, but becoming drowsy is always a bummer to my day. I would say that it is up to the individual to determine what works best for their body.

Does Allegra cause weight gain?

This is a tricky question and I would say that it all depends on the individual’s health. I can tell you that all antihistamines do not affect my appetite in a significant way, but some insist that the psychiatric effects of Fexofenadine increase their appetite for more unhealthy food items. Of course, that can be a problem to consider if you are affected in this way. However, this stuff does not directly cause you to gain weight because it has nothing to do with calorie or sugar intake, which is generally the root cause of weight gain and obesity.

Does Fexofenadine make you drowsy?

This antihistamine makes some people drowsy, but it does not seem to be a major problem that is frequently talked about, unlike Benadryl and Zyrtec. Perhaps I have experienced slight drowsiness when taking Allegra, but it wasn’t significant enough to be a problem. That’s why I prefer to take it in the morning. But everyone will experience things differently.

Does Allegra expire and what is its shelf life?

Yes, this drug does expire eventually. Fexofenadine has a shelf-life of about 3 years. You shouldn’t take it after this time because many people have reported severe rashes and other symptoms as a result.

Does Fexofenadine cause anxiety or depression?

This doesn’t seem to be a problem for this medication in particular. It seems that Benadryl and Zyrtec have caused significant problems for some people suffering from mental illness. Personally, I haven’t noticed a mental difference when taking Allegra allergy medicine.

Is Allegra allergy or Fexofenadine an antihistamine or steroid?

Fexofenadine is an antihistamine, not a steroid. Usually, nasal sprays contain steroids to physically relieve inflammation in your sinuses.

Does Allegra keep you awake or cause insomnia?

No, it does not seem to have any stimulating effects at all. In fact, it might even make you slightly drowsy during the night time, actually helping some people fall asleep. Perhaps something else is keeping you up at night that we can discuss in the comments below.

  1. Thanks for the review on Allegra. I have had similiar results to Allegra in comparison to the others like Claritin or Zyrtec. Allegra has been the most effective for me. I also take Nasonex with my Allegra and this combination has drastically improved my allergy symptoms. However, I am starting to feel like I need it more throughout the year than just during the Spring, which is when I started using it initially.

    I have seasonal allergies, allergies to types of trees and grass outdoors, a long list food allergies and sensitivities (to foods I’ve eaten all my life but I just found out 8 years ago) and to formaldehyde.

      Thanks for visiting! Allegra has been very effective for me as well, when it comes to OTC antihistamines for allergies. However, it gave me some strange psychological symptoms when I tried to come off of it. Allegra gave me hallucinations in my peripheral vision. I would see shadow people and geometric gray patterns and the headache that accompanied was terrible. That’s why my review suggests that you try natural methods for allergies instead. Best to avoid a potential addiction and future problem.
