Do Antihistamines Cause Dementia
Long term use of some antihistamines may increase your risk of dementia. Diphenhydramine blocks the effects of a neurotransmitter called acetylcholine. This neurotransmitter is vital for memory and learning. Diphenhydramine increased the risk of dementia by 54% in one 3,000 patient study followed for seven years.
What Other Treatments Can I Try For Allergies
If you are concerned about an antihistamines side effects or drug interactions, there are alternative treatments.
Allergy sprays can be an effective treatment option. Nasal corticosteroids are safe for daily use and dont cause the same systemic side effects or interactions that daily pills can.
containing the active ingredient pseudoephedrine, like Sudafed, or phenylephrine, like Sudafed PE, help relieve nasal congestion and sinus pressure due to the common cold, sinusitis, allergic rhinitis, or hay fever.
Immunotherapy is a long-term treatment that decreases your sensitivity to allergens over time. By exposing your body slowly to the allergens that trigger your symptoms, youre able to build up a tolerance to the allergens. Immunotherapy is safe for both children and adults, but treatment can take up to 18 months to see an improvement in symptoms.
Lifestyle changes, such as reducing your exposure to allergy triggers or using a HEPA air filter, can help reduce your chance of experiencing symptoms during peak allergy season. If you feel like your antihistamine is no longer working, try a different one or consult with your allergist for more information.
Come Up With A System
I establish a system and modify it as needed. I tried using pillboxes to help me take the correct doses of medicines at the right times each day. But I liked keeping my pills in small plastic bags instead. Now that I have a child at home, I store all medicines in their original, child-proof bottles out of my child’s reach.

There are a few things you can do as the adult in the house to help prevent an overdose from diphenhydramine and all other drugs that may be in your home.
What Is Benadryl How Is It Taken Safely
Benadryl was the first antihistamine to receive approval from the Food and Drug Administration . The brand name was acquired by Johnson & Johnson in 2007 and the medication remains a widely-used treatment for allergies and mild cold symptoms.1
Since the medication has been available for several decades, safe dosage and elimination time are well understood. Benadryl is available in a variety of formulations, including tablets, liquid gels, and chewables. The standard dose of diphenhydramine in brand name Benadryl is 25 mg per dose for adults and 12.5 mg per dose in childrens formulas. For the average healthy adult, elimination half-life ranges from 6.7 to 11.7 hours.2 So between 6 to 12 hours after taking Benadryl, half the drug will be eliminated from the body. Within two days, the drug will be completely gone from the body.

How And When To Take Prednisolone
Take prednisolone exactly as your GP has advised.
Usually, youll take a single dose once a day in the morning so it does not:
- upset your stomach
- keep you awake at night
Your GP will decide on the dose. They might tell you to take it on alternate days.
In children, the dose is calculated based on their height and weight. So it may be lower than for an adult.
What To Take Instead
Nasal steroid sprays. These are actually the first line of treatment for people with seasonal allergies, and studies show they can be even more effective than oral antihistamines. Three that McGrath recommends are Nasacort AQ and Rhinocort Aqua , and Flonase Sensimist, an over-the-counter product.
To maximize effectiveness, use them the right way: Be sure to spray slightly to the outside of the nostril. Use the right hand to spray up the left nostril and the left hand to spray up the right nostril, McGrath says. You do not want to spray into the middle of your nose, the septum, as this causes increased risk of nosebleeds and irritation.
Certain over-the-counter oral antihistamines. If a nasal steroid spray isnt enough, you can pair it with an over-the-counter antihistamine. McGraths first choice for older adults is Allegra 180 mg. Its nonsedating as it does not cross the blood-brain barrier, so it doesn’t cause any drowsiness, he explains. If you dont have that on hand, he suggests Xyzal, which he says is less sedating than other brands.
Allergy immunotherapy. These are regular injections over a period of time generally around three to five years to stop or reduce allergy attacks. Each allergy shot contains a minuscule amount of what youre allergic to, to stimulate your immune system.

Zyrtec Side Effects To Be Aware Of
If you’ve ever slept 14 hours after popping a Benadryl, you’re well aware that some allergy meds can seriously knock you out. That’s not as common with Zyrtec, but 11 to 14 percent of people do report feeling sleepy after taking it, making it the most common side effect reported, says Boomershine.
Since the effects of Zyrtec last 24 hours, drowsiness can hit at any time. Avoid alcohol and be careful about driving if the med hits you with the sleepies, per the Zyrtec site.
Its annoying to feel as if youve inhaled a mouthful of sand. Less than 10 percent of Zyrtec poppers will wind up with a dry mouth, says Boomershine. When you have an allergic response, your tissues secrete more fluid , and antihistamines dry you up. She says that drinking water will help, as will switching to an alcohol-free mouthwash if youre using one that has alcohol in it, as that ingredient also dries you out.
Dizziness can be a rare potential side effect and may disappear after your body adjusts to the medication, per The Mayo Clinic. Give it time, but always check in with your doctor if youre concerned. And, just like drowsiness, hold off on driving if youre getting dizzy spells.
While Zyrtec may make adults sleepy, it can turn kids into little insomniacs, says Boomershine. Having them take the long-acting med earlier in the day wont help either since it lasts all day. Talk to their pediatrician about making a switch.
What Should I Avoid While Taking Allergy Relief
Allergy Relief may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Drinking alcohol can increase certain side effects of chlorpheniramine.
Ask a doctor or pharmacist before using any other cold, cough, allergy, or sleep medicine. Antihistamines are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Allergy Relief can decrease sweating and you may be more prone to heat stroke.

Are Antihistamines Safe For Dogs
Diphenhydramine is a common medication used to treat allergies, hives, food allergies, anxiety and other conditions in dogs. However, you should consult your veterinarian about the use of diphenhydramine in your pet. The dosage in dogs is based on their weight plus your veterinarian will want to examine your dog to be sure an antihistamine is the correct drug for the correct diagnosis. If an antihistamine is needed, your veterinarian will want to prescribe a brand that is specific to animals and at a dosage correct for your pet.
Is It Safe To Take Zyrtec Every Day
Yep. “When taken in the recommended doses, antihistamines can be taken daily. This is especially true with Zyrtec, since it doesn’t show decreasing effectiveness if used daily,” says Sima Patel, MD, an allergist at New York Allergy & Sinus Centers.
Zyrtec and other allergy medicines currently on the market are known as second-generation antihistamines, and have fewer and less severe side effects than the “first generation” of allergy medications did. So though you might experience some side effects while on allergy medicine, they shouldn’t persist once you’ve stopped taking it.
Still, it’s probably worth holding off on medication that you don’t need, says Dr. Patel. So if you aren’t having allergy symptoms or they get milder during a certain time of the year, that’s probably a good time to take a Zyrtec break. “We always want the least amount of medication to control symptoms. However, starting allergy medications two weeks prior to your symptomatic season is best to help prevent symptoms,” Dr. Patel says.
Mild side effects may be totally normal, but if you’re experiencing severe side effects, or persistent ones that just won’t go away, it’s best to talk to your doctor before you continue regular use of Zyrtec to see if its right for you.

Several Factors Impact How Quickly Benadryl Is Metabolized Including: 3
- Age: Adults over 65 years old and children younger than 12 years old metabolize diphenhydramine more slowly, so lower doses less often are safer.3
- Liver problems: Since the active ingredient in Benadryl is processed through the liver, anyone with decreased hepatic function will have difficulty safely consuming this drug.
- Kidney problems: The kidneys help to process toxins by passing them out through the bladder. People who have decreased renal function may have a tough time metabolizing Benadryl. Urinary pH can also impact how the body processes diphenhydramine.
- Hydration: People who do not drink sufficient water may struggle to eliminate diphenhydramine from their system.
- Low vs. high dose: Even healthy adults who take more than the recommended dose of Benadryl will experience consequences, such as taking longer to metabolize the drug. Taking the recommended dose of Benadryl for longer than recommended may also lead to tolerance as the drug builds up in the body, and that also might increase the medications elimination time.
- Other medications: Taking prescription drugs, or other over the counter drugs, along with Benadryl may change how the body metabolizes all the substances together.
- Body weight/mass: Different body types process different amounts of medication at different rates. This is true for prescription drugs, recreational substances like alcohol, and over the counter drugs like Benadryl.
Behind The Benadryl Challenge And Why Its Harmful
Teenagers are no strangers to taking on challenges. However, there is a challenge thats sweeping across social media networks, and has the potential to be deadly. The Benadryl Challenge has been made popular on TikTok, urging viewers to take large doses in some cases as much as 10 times the normal dose of the drug diphenhydramine in order to give the user hallucinations or a trip.
We talked to Frank Cunningham, M.D., director of the Pediatric Emergency Department at JFK University Medical Center to learn why the Benadryl Challenge is so harmful and things you can do as a caregiver to help.
Dr. Cunningham says that diphenhydramine, known more commonly by the brand name Benadryl, is an antihistamine and is commonly used in the treatment of allergies. The dose of Benadryl that kids are taking to hallucinate is very close to the dose that could be life-threatening.

How Do I Safely Take Otc Antihistamines
Read the directions on the label before taking any medicine. Learn how much to take and how often you should take it. If you have any questions about how much medicine to take, call your family doctor or pharmacist. Keep track of which OTC medicines you are using and when you take them. If you need to go to the doctor, take the list with you.
Follow these tips to make sure you are taking the right amount of medicine:
- Take only the amount recommended on the medicines label. Dont assume that more medicine will work better or quicker. Taking more than the recommended amount can be dangerous.
- Mixing medicines can be dangerous. If you take a prescription medicine, ask your doctor if its okay to also take an OTC antihistamine.
- Dont use more than 1 OTC antihistamine at a time unless your doctor says its okay. They may have similar active ingredients that add up to be too much medicine.
Is Mixing Allergy Meds Safe
You can safely mix different types of allergy medications, like Flonase, a nasal spray, and Claritin, an antihistamine. In fact, its often recommended by doctors. Choosing two allergy treatments that you take through different routes, like taking a pill and using eye drops, can decrease the risk of interactions between the medications.
While antihistamine pills can and are frequently combined with oral decongestants, like pseudoephedrine , they can have some adverse side effects. This can cause headaches, lightheadedness, a dry nose, and more. It is important that you talk with your doctor if you experience side effects from your medications.
It is not recommended to combine steroid nasal sprays with each other and it is not safe to mix different types of antihistamine allergy pills. If your allergy treatments are not as effective as you need, consult your doctor to adjust the dosage or your medication.
