What is the best over the counter non drowsy allergy medicine

Allergic reactions can include rhinitis (inflammation of the nasal passages, also known as "hay fever"); asthma; skin allergies; or rarely, anaphylaxis, which is a potentially fatal allergic reaction that requires emergency treatment and may produce vomiting, diarrhea, difficulty breathing or a drop in blood pressure.

After obtaining your medical history and conducting a thorough examination, your physician can determine whether your difficulties do indeed stem from allergies; if so, your physician can offer you one or more of the following options for relieving your symptoms:

Bronchodilators

Bronchodilators are available as inhalers, pills, liquids, and injections to treat asthma.

Prescription-Strength Antihistamines and Decongestants

Prescription-strength antihistamines and decongestants are often the same strength as OTC varieties.

Clarinex (desloratadine) is only available with a prescription.

Corticosteroids

Corticosteroids are anti-inflammatory medicines come in several forms, including nasal sprays love Flonase (fluticasone). Corticosteroids also come as inhalers, pills, and injections. Inhalers are often prescribed for the long-term management of allergy-induced asthma. Topical creams and ointments are used to treat skin-related allergy symptoms.

Potent Corticosteroid Drugs Tame Inflammation Quickly

Anti-Leukotrienes

Medications love Singulair (montelukast sodium) are anti-leukotrienes, which are used to treat allergic rhinitis as well as asthma by fighting chemicals called leukotrienes, which increase inflammation.

Anti-Immunoglobulin (IgE) Antibodies

People with severe, persistent asthma due to allergies may benefit from anti-IgE antibody injections, which prevent the release of histamine. These antibodies also cause the symptoms of rhinitis, but their use for that condition has not been approved because of the availability of other, less-expensive remedies that do not require injections.

Your doctor or physician can also refer you to an allergist for further examination.

An allergist can act out allergy skin or blood tests and give allergy shots if needed.

Allegra and Zyrtec are both antihistamines, but is one more effective or less likely to cause sedation than the other?

Allegra has the lowest risk of sedation out of every antihistamines so is preferred if an antihistamine is needed for people working in safety-critical jobs. Even though Zyrtec is 3.5 times more likely to cause sedation than Allegra, it is still much less sedating than some older antihistamines such as promethazine.

Other differences:

  1. Allegra should not be taken with grapefruit juice.

    Zyrtec has no reported food interactions.

  2. Allegra works within two hours and Zyrtec works within one hour.
  3. Several studies own found cetirizine (Zyrtec) to be more effective than fexofenadine (Allegra) at relieving symptoms of allergic rhinitis and urticaria, and it appears to own a longer duration of action.
  4. Studies own not compared the effects of Allegra and Zyrtec for conditions such as postnasal drip, but research suggests intranasal antihistamines such as azelastine are more effective.
  5. Zyrtec and Allegra should not be taken at the same time, instead, if symptoms are persisting, it is better to take another drug with a diverse mechanism of action.

Allegra is a brand name for the drug fexofenadine and Zyrtec is a brand name for the drug cetirizine.

Both fexofenadine and cetirizine are favorite antihistamines with numerous similarities but there are some significant differences.

Which is more sedating? Allegra or Zyrtec?

Allegra (fexofenadine) and Zyrtec (cetirizine) are second-generation antihistamines. Second-generation antihistamines were first developed in the 1990s to provide allergy relief without the unwanted side effect of sedation common to first-generation antihistamines such as promethazine and diphenhydramine. However, it soon became apparent that not every second-generation antihistamines were equal when it came to not causing drowsiness or affecting other thought processes.

Cetirizine is significantly more likely than fexofenadine to cause drowsiness.

Fexofenadine (Allegra), even in dosages exceeding those recommended, is the least sedating of every second-generation antihistamines, so is considered the antihistamine of choice for people in safety-critical jobs such as airline pilots.

Which is more effective for Allergic rhinitis?

Trials own shown both Allegra (fexofenadine) and Zyrtec (cetirizine) are significantly more effective than placebo (a pretend pill) for reducing symptoms associated with allergic rhinitis, hay fever, and other allergies.

Trials own not consistently shown that one antihistamine is more effective than another; however, one trial reported cetirizine produced a 26% greater reduction in the number of allergic rhinitis symptoms at 12 hours and 14% greater reduction in symptoms overall compared with fexofenadine. Cetirizine also appeared more effective for symptoms such as runny nose, sneezing, itchy/watery eyes, and itchy nose, mouth or throat. Cetirizine was slightly more likely (0.8%) than fexofenadine to cause drowsiness.

Another trial reported similar findings (33% greater reduction in allergic rhinitis symptoms) and also found cetirizine had a longer duration of effect.

Intranasal or ophthalmic (into the eye) antihistamines own a quicker onset of action than oral antihistamines (within about 15 minutes); however, they need to be istered several times daily. In people with allergic rhinoconjunctivitis and predominantly eye symptoms, ophthalmic antihistamines work much quicker (within 3 to 15 minutes) and are much more effective than any other form of treatment. Intranasal antihistamines are as effective as intranasal cromolyn, intranasal nedocromil, and leukotriene modifiers in seasonal allergic rhinitis; however, are not as effective at relieving nasal congestion and other symptoms as intranasal glucocorticoids.

Allegra Vs Zyrtec for urticaria and other skin reactions

All second generation antihistamines, including Allegra and Zyrtec, are effective for acute and chronic urticaria, although more trials own been conducted in people with chronic urticaria.

One trial found cetirizine to be more effective than fexofenadine at relieving symptoms in 97 patients with chronic urticaria with 51.9% of participants taking cetirizine reporting themselves as symptom-free after 28 days of treatment compared with only 4.4% of participants taking fexofenadine. Partial improvement was reported by 36.5% of people assigned cetirizine (42.2% assigned fexofenadine) and 11.5% experienced no improvement with cetirizine (53.3% with fexofenadine). No difference in side effects was noted between the two.

Allegra Vs Zyrtec for Postnasal Drip

Post nasal drip may happen for various reasons — allergies (particularly to dairy), colds or flu, various drugs (including birth control pills and high blood pressure tablets), freezing temperatures, bright lights, hormonal changes and spicy foods.

Thin postnasal drip secretions caused by allergies may be treated with antihistamines.

Second-generation antihistamines such as Allegra and Zyrtec may offer better relief than older-type antihistamines such as promethazine (older antihistamines tend to thicken post-nasal secretions). Intranasal antihistamines, such as azelastine, own a faster onset of action (15 minutes) and appear more effective than oral antihistamines although require more frequent istration.

What is the best over the counter non drowsy allergy medicine

Other treatments include decongestants, cromolyn, and corticosteroid nasal sprays.

In the treatment of post nasal drip caused by nonallergic causes, oral second-generation antihistamines are not extremely effective. However, the intranasal antihistamine azelastine is effective.

What is the best over the counter non drowsy allergy medicine

Azelastine improves every rhinitis symptoms including nasal congestion, postnasal drip, sneezing and sleeping difficulty. The most common side effect is a metallic aftertaste; however, this is more likely at higher dosages and tends to dissipate with continued use.

Allegra Vs Zyrtec To Relieve Freezing Symptoms

Second-generation antihistamines (such as Allegra and Zyrtec) own limited effectiveness at relieving symptoms of freezing such as a runny nose and sneezing (only 45% of adults felt better after using them compared to 35% with placebo [a pretend pill]). Effects were only noticeable if used within the first two days of a freezing, use of antihistamines made no difference thereafter.

Allegra Vs Zyrtec: istration

The antihistamine effects of Allegra and Zyrtec final for at least 24 hours, therefore, they are both given once daily.

Fexofenadine, the athletic ingredient of Allegra works within two hours. Cetirizine, the athletic ingredient of Zyrtec works within one hour.

Allegra Vs Zyrtec: Side Effects, Interactions and Price

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea. Zyrtec is 3.5 times more likely than Allegra to cause sedation; however, Zyrtec is still much less sedating than older antihistamines such as promethazine.

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea.

Every the second generation antihistamines currently on the market appear free from adverse cardiovascular effects. Few major interactions own been reported with either Allegra or Zyrtec; however, there is the possibility that side effects such as sedation, confusion, and mental alertness may be enhanced if given with other drugs with this side effect.

Grapefruit juice appears to decrease the rate and extent of absorption of fexofenadine (Allegra) by about 30%. Cetirizine (Zyrtec) has no reported interactions with grapefruit or grapefruit products. More studies are needed to determine if there are any interactions between second generation antihistamines and herbal products and other types of food.

Always speak with your doctor of pharmacist before using any drugs in combination.

Cost is similar for 30 Allegra and 30 Zyrtec tablets and both are available as generics.
