Discover the best allergy medicine for effective relief from seasonal allergies, hay fever, and other allergy symptoms. Combat sneezing, itchy eyes, and nasal congestion.

Seasonal allergies hit millions in the U.S. yearly.1 Finding the right allergy medicine means lessening sneezing, itchy eyes, and a runny nose. This guide shows different allergy medicines. It tells how to use them for longer relief.

Key Takeaways

  • Antihistamines like Cetirizine and Loratadine are less likely to cause drowsiness compared to older antihistamines.2
  • Decongestants can cause side effects like trouble sleeping, headaches, and increased blood pressure.2
  • Corticosteroid nasal sprays can relieve stuffiness, sneezing, and runny nose but may have side effects.2
  • Mast cell stabilizers and leukotriene inhibitors can help prevent and relieve allergy symptoms.2
  • Immunotherapy and biological medications offer long-term allergy relief for some individuals.2

Understanding Allergy Medications

Allergy medicines come in many forms. You can get them as pills, liquids, and more. Some are easy to buy, while others need a doctor’s note. The main types include antihistamines and corticosteroids. There are also decongestants and other special kinds.2 Each one works on specific allergy signs like itching and sneezing. They even help with blocked noses and swelling. Knowing about these can help you pick the best one for you.

Types of Allergy Medicines

Antihistamines help with allergy symptoms but can make you tired. Options not likely to make you sleepy are available too.2 Decongestants like Sudafed are often mixed with antihistamines for extra help. This mix is useful for allergies that bring both sneezing and stuffiness.2 Nasal sprays with corticosteroids help open your nose and stop sneezing. They can cause slight irritation in your nose.2

Symptoms Targeted by Different Medications

Inhalers with corticosteroids and bronchodilators are for asthma.2 In severe cases, you might get oral corticosteroids, but they can have bad side effects.2 Immunotherapy involves getting shots to build up a tolerance. This can teach your body not to overreact to allergens.2 For some, there are tablets you put under your tongue. These tablets help with pollen and dust allergies.2 Injections known as biological medicines target certain immune responses. Their main side effects include some irritation at the injection site.2

Pollen from trees causes allergies in early spring.3 By late spring and early summer, grass pollen is a big issue.3 Later in the year, weed pollen, especially from ragweed, can cause allergies too.3 Some molds also trigger allergies.3 The amount of pollen in the air changes from place to place.3 Be careful, as some antihistamines may make you drowsy. This can affect your ability to drive or use machines.3 Nasal sprays with corticosteroids help with stuffy nose and swelling.3 Decongestants, which you can also find as nose sprays, are good for short-term use.3 The kind with pseudoephedrine is not out on shelves to stop it from being misused.3 If you use nose sprays with decongestants too much, it can backfire. It can make the stuffiness worse.3

Allergy shots increase your tolerance to allergens over time.3 They are given as shots or tablets under the tongue.3 Taking tablets under the tongue should start a few months before your allergy season. This way, it works best.3 Make sure to read the label on nonprescription medicines before giving them to kids.3 Some allergy medicines are not for kids under 12, so be careful.3 Doctors recommend special medicines if children have allergies.3

Antihistamines: Battling Histamine

Antihistamines stop histamine from causing allergy symptoms.4 First-generation antihistamines can make you sleepy because they travel to the brain easily. This includes drugs like Chlor-Trimeton and Benadryl.4 On the other hand, second-generation antihistamines, like Zyrtec and Claritin, don’t make you as sleepy. They don’t move into the brain as much.4

Oral Antihistamines

Oral antihistamines relieve runny noses, itchiness, and watery eyes.5 They ease hive symptoms too. Second-generation ones cause less sleepiness than the first.5 Antihistamines work their best between 30 minutes and 3 hours after you take them.5

Antihistamine Nasal Sprays

Antihistamine nasal sprays, such as Astelin and Patanase, help with nasal problems.4 They reduce swelling and make your nose feel less stuffed quickly.4

Antihistamine Eye Drops

Antihistamine eye drops ease itchy, red, and swollen eyes.4 Drugs like Alaway and Pataday stop histamine reactions in the eyes. This helps with allergy eye symptoms.4


Corticosteroids: Reducing Inflammation

Corticosteroids are great at reducing inflammation, which is good for fighting allergy symptoms.2 Things like nasal sprays can really help with a stuffy nose, sneezing, and runny nose.2 They’re a common choice for dealing with allergies or asthma from things in the air.2 If your eyes are itchy, red, or watery, special eye drops can calm them down.2

Corticosteroid Nasal Sprays

2 Corticosteroid nasal sprays do a lot by easing the swelling in your nose. This helps with symptoms like a stuffed-up nose, sneezing, and a runny one.2 You might take these sprays every day to keep chronic allergy symptoms in check.2

Inhaled Corticosteroids

2 People turn to inhaled corticosteroids for asthma that gets worse around certain allergens. These drugs keep the swelling in the airways down. As a result, you see less wheezing, coughing, and find it easier to breathe.

Corticosteroid Eye Drops

If your eyes just won’t stop being itchy, red, and watery, there’s relief in corticosteroid eye drops.2 Drugs like fluorometholone (Flarex) and loteprednol (Alrex) bring down the inflammation in your eye, making you feel better.

Oral Corticosteroids

Corticosteroids you take by mouth, such as prednisone, might be a last resort for severe allergy reactions.2 Yet, they can cause more side effects than sprays or eye drops.6 These side effects include anxiety, depression, and changes in vision, among others.6 Doctors try to use the smallest effective dose to limit risks and change it as needed.6 Using too much can be very dangerous.6

Decongestants: Relieving Nasal Congestion

Decongestants lessen the swelling and inflammation in your nose. This eases breathing when you’re congested.4 However, decongestants should not be used if you have conditions like high blood pressure or heart problems.4

Oral Decongestants

Oral decongestants help with congestion due to allergies.4 Sudafed and Sudafed PE are common decongestant pills you can find at the store.4

Nasal Decongestant Sprays and Drops

Nasal sprays like Afrin or Tyzine give fast relief. But only use them for a little while to avoid making your congestion worse later.42 Sprays like Afrin and Tyzine are examples. They’re good for a quick fix but don’t use them for more than three days straight.2

Combination Decongestant-Antihistamine Products

Some allergy medicines fight congestion and other symptoms. Things like Zyrtec-D and Allegra-D are good examples.4 They combine decongestants and antihistamines for better allergy relief.2 You can find these combos in products like Zyrtec-D 12 Hour, Clarinex-D, and more.2

best allergy medicine: A Comprehensive Guide

Evaluating Effectiveness

When picking the best allergy medicine, effectiveness and side effects matter.2 Some work quickly but might make you feel tired or raise your blood pressure. Others are gentler but take more time to work.7 The gravity of your symptoms and your health conditions play a role.2 Talking to your doctor is key to finding the right one for you.

Considering Side Effects

Thinking about the best allergy medicine means also thinking of the side effects.2 Drowsiness can come from drugs like Diphenhydramine and Chlorpheniramine. Those that cause less sleepiness include Cetirizine, Desloratadine, Fexofenadine, Levocetirizine, and Loratadine.2 Decongestants like pseudoephedrine may cause problems sleeping, headaches, high blood pressure, and irritability.2 Knowing these effects helps you and your doctor make a smart choice for relief.

Mast Cell Stabilizers: Blocking Chemical Release

Mast cell stabilizers stop the body from releasing chemicals like histamine. These chemicals cause allergy symptoms.8 Drugs that stabilize mast cells help avoid allergic reactions from common allergens. This includes conditions like bronchial asthma, allergic conjunctivitis, and vernal keratoconjunctivitis.8 Finding new and more affordable mast cell stabilizers that need less frequent dosing is crucial.8

Nasal Mast Cell Stabilizers

Nasal mast cell stabilizers can prevent or relieve issues like nasal congestion and sneezing.9 They include cromolyn sodium, lodoxamide, and pemirolast. These drugs stop mast cells from releasing their contents. But, they might take days to weeks to work fully.9 Lodoxamide is particularly good at making the mast-cell membrane stable. In fact, it’s 2500 times more effective than cromolyn sodium at this.9

Eye Drop Mast Cell Stabilizers

For eye problems like itching and watering, eye drops with mast cell stabilizers are helpful. These include cromolyn, lodoxamide, and nedocromil. They can ease symptoms.9 The human eye has millions of mast cells.9 Loteprednol etabonate (0.2%) helps with eye allergies for a short time.9 But, it does not have a 100% positive effect.9 Another medicine, emedastine difumarate (0.05%), increases the risk of headaches by 11%.9 Yet, levocabastine hydrochloride works fast and lasts about 4 hours.9 Olopatadine hydrochloride (0.1%) lasts at least 8 hours.9 However, ketotifen fumarate (0.025%) may cause side effects in about 10 to 25% of people.9 Alcaftadine 0.25% works quickly and its effect can last up to 16 hours. This was found in a study on allergic conjunctivitis.9

Mast cell stabilizers are quite safe, but they might take some time to start working fully.8

Leukotriene Inhibitors: Targeting Leukotrienes

Leukotriene inhibitors are prescription drugs like montelukast (Singulair). They work by stopping the effects of leukotrienes, which cause allergy symptoms. These symptoms include a stuffed-up or runny nose and sneezing.2 Although helpful in treating hay fever, leukotriene inhibitors can also lead to psychological side effects. Some people might experience anxiety, depression, and even have thoughts of hurting themselves.2

There are different types of leukotriene modifiers such as montelukast, zafirlukast, and zileuton.10 Montelukast can treat asthma and allergies, while zafirlukast and zileuton work for asthma only.10 These modifiers are great at making breathing easier, helping one exercise with breathing issues, keeping airways clear, and reducing chest and throat mucus. They also prevent allergy and asthma attacks, making them lighter and less often.10

Montelukast and zafirlukast stop a certain leukotriene receptor and are good for asthma in the long run.11 Montelukast can also help with hay fever symptoms. Yet, it’s advised to not use montelukast alone as the first treatment for hay fever.11

Using leukotriene inhibitors is effective for some allergy symptoms. But, it’s key to understand possible side effects. Always work closely with your doctor for the best treatment plan.21011

Allergen Immunotherapy: Long-Term Relief

Allergen immunotherapy, known as allergy shots or desensitization, offers lasting relief.2 It involves a series of injections with more and more allergens.2 This trains the immune system to not overreact to the triggers over time.

Allergy Shots

Allergy shots, or SCIT, use a common method for fighting allergies.2 They expose the body to small doses of allergens like pollen or pet dander.2 This exposure helps the immune system learn not to react strongly to these substances, reducing symptoms.

Sublingual Immunotherapy (SLIT)

In SLIT, the allergen extract goes under the tongue to be absorbed.12 This method gradually reduces the body’s allergic responses by introducing small amounts of allergens.12 It’s done through FDA-approved tablets or customized drops, depending on the allergen.12

Both allergy shots and SLIT are good at easing many allergy symptoms, including congestion and itchy eyes.212 They offer solid, long-lasting relief for those with intense seasonal allergies.

Biological Medications: Targeting Specific Reactions

Biological medications are a new kind of allergy treatments aiming at precise immune reactions. They include drugs like dupilumab for allergic skin cases and omalizumab for asthma or hives that don’t improve with normal meds.13 These medicines go directly to the source, shutting down harmful protein or cell actions. But, they might make the skin where you get the shot red, itchy, or sore.

13 The FDA has given the thumbs up to Xolair, Nucala, Fasenra, Cinqair, Dupixent, and Tezspire for severe asthma.13 For some, they help cut down how often asthma hits.13 Doctors use a few tests to find which biologic best suits your asthma type.

13 Using biologics can lower your chances of bad asthma attacks and visits to the ER. They also mean you won’t need as many other asthma drugs, making your lungs work better.13 They don’t replace your rescue inhaler but offer another layer of help.13 Each biologic focuses on a different cause of asthma, helping your body fight back in its unique way.

14 Xolair is great for tough allergic asthma.14 Nucala helps with eosinophilic asthma.14 Fasenra, approved in 2017, battles against severe eosinophilic asthma.14 As for Cinqair, it’s for older eosinophilic asthma patients to prevent severe attacks.14 Altus Biologics specializes in setting up biologic treatments in healthcare settings, making it easier for doctors to give these needed treatments.

15 Five biologics are approved for allergic asthma, with Xolair designed just for this. The others help with eosinophilic asthma.15 Omalizumab, though an injection, is good even for kids 6 and up.15 They cut down ER trips, need for steroids, and help you breathe better, plus making your usual asthma drugs do more.15 And the best part? They’re safer than regular steroids, which can do more harm.

15 Biologics, by choosing which asthma parts to attack, cause less whole-body trouble than steroids.15 They do lower some of your immune system, and that can raise the risk of certain infections, although very rare.15 Side effects are usually minor, like a sore throat or muscle pain, but a doctor will keep an eye on you for a bit after your shot just in case.

Emergency Epinephrine Shots: Treating Anaphylaxis

Epinephrine shots are given using devices like EpiPen or Auvi-Q to counter anaphylaxis, a severe allergic reaction.16 Anaphylaxis may cause a tight throat, trouble breathing, and a quick blood pressure drop.16 Those at risk should have an auto-injector for emergencies.16 Knowing how to use it and getting help right away is crucial.

17 These shots treat reactions to bug bites, foods, drugs, latex, and more.17 They work by opening airways and tightening blood vessels, countering anaphylaxis.17 The shot is given just under the skin or into a muscle for it to work.

16 Anaphylaxis can hit fast after contact with an allergen. Without treatment, it can prove fatal within 30 minutes in some.16 Antihistamines like Benadryl aren’t strong enough for anaphylaxis.16 Things like meds, latex, foods, and insect bites often cause it.

16 Carrying an epinephrine shot is vital if you’ve had bad allergic reactions before.17 It’s wise to have two shots because one might not be enough.17 A shot usually has only one use of epinephrine.

16 Anaphylaxis needs several hours of hospital care afterward.16 If someone stops showing signs like breathing or moving, do CPR fast.16 Anaphylaxis signs can come back, needing rapid care again.

16 Trust in guides like The Merck Manual for battling anaphylaxis.17 If symptoms continue after a shot, a doctor might say to use another.17 More than two shots in an episode are for pros to decide.

Managing Seasonal Allergies

Seasonal allergies impact millions every year. It’s tough to handle these conditions.18 Symptoms often include sneezing, congestion, and a runny nose. These effects can make daily life hard.18 The spring season is a big trigger for these allergies. Pollen in the air can worsen the symptoms a lot.18 Besides taking medications, there are many ways to cope with seasonal allergies.

Reducing Exposure to Allergens

To deal with seasonal allergies, it’s smart to cut down on things that trigger them. For example, it helps to stay inside with windows shut on windy days. Also, try not to be outside when pollen is high.18 A face mask can be useful during yard work.

Monitoring Pollen Counts

It’s also key to keep an eye on pollen levels. Checking pollen forecasts helps plan ways to avoid it.18 This way, people can adjust their activities to limit allergy reactions.

Keeping Indoor Air Clean

Keeping the indoor air clean is another good idea. Use air conditioners and dehumidifiers to keep the air fresh. Also, high-efficiency filters can help.18 These changes make the living space less likely to cause allergy problems.

Oral Decongestants (Pseudoephedrine)These help with stuffy noses and are sold over-the-counter.2
Combination Antihistamine-Decongestant Medications (Zyrtec-D, Clarinex-D, Allegra-D, Claritin-D)They offer both antihistamine and decongestant in one form.2
Corticosteroid Nasal Sprays (Budesonide, Fluticasone, Mometasone, Triamcinolone)These are recommended first for allergies. But, they may take a while to work.19
Mast Cell Stabilizers (Cromolyn Nasal Spray)These sprays work differently and need to be used more often. They can take a month to show effect.19

Although over-the-counter options and alternative treatments can help, talking to a healthcare provider is key. They can guide you to the best and safest strategies for your allergies.

When to Consult a Healthcare Professional

If your allergy symptoms keep happening or get worse, even after trying over-the-counter or home treatments, you should see a healthcare pro. A specialist, like an allergist or immunologist, can do tests to find out what you’re allergic to.20 Knowing this helps them pick the best treatment, which could be medicine, shots, or both. They’ll also check how bad your allergies are and if you might have asthma or other serious problems. Then, they’ll suggest what you should do next.

If store medicines don’t help or if you’re not sure what’s causing your symptoms, it’s a good idea to talk to a pro.20 They can figure out the best way to handle your allergies. This may stop any bad issues from happening later on.
