Allergies are problems confronting the immune system in which there is a reaction of the immune system with environmental substances. This reaction causes inflammations, such as sneezing and asthma. Doctors test for allergies in various ways: they can draw a table of many squares on the back of a person; put a lot of different allergens on the skin with each in the different squares; after few seconds, if any raised area is noticed in any of the squares, then the person is possibly allergic to those different substances. The commonest type of allergy is seasonal allergies associated with pollens grains that emerge from plants that blossom, and dust. These floating and airborne particles affect the lungs, throat, eyes, nose and skin. Hay fever is associated with many symptoms which stimulate a terrible cold. Most hay fever come during the spring period when all plants nectars blossom, or in the fall as many things begin to dry out and particles fill the drier air.

Allergy medicationsThere are various allergy medications and treatments. If a person is suffering from an allergic reaction the most common medication is an anti-histamine. Conversely, most anti-histamines cause drowsiness, it is, therefore, impractical to be taken for long term use. Drug prescription companies have designed many types of “non-drowsy” medication that allows patients to take one pill daily to fight their allergies.

There are many theories that is tied around the reasons why people get allergies, but no one is pretty certain. The major theories are:

  • Hereditary
  • Hygiene
  • Environmental factors.

Some scientists and researchers believe that allergies are passed down through genes. Children who have allergies are likely to have parents who have the same allergies. Others believe that they are caused by a change in the life we human now live. A human may get allergies because they keep too much hygiene within the body and environment making certain pathogens that help the immune system strengthen non-effect.

Allergy Medications

Allergy medications are available as either pill, liquids, nasal sprays, eye-drops, inhalers, skin creams and injections. Some allergy medications exist as over-the-counter medications while others are available by prescription only. Below reveals the summary of the various types of allergy medications and why they are used.

Antihistamines

When the body comes into contact with whatever your allergic trigger is, whether pollen, ragweed, dust mites, pet dander for example – it generates a chemical known as histamine. Histamines cause the tissue in the nose to swell, the nose and eyes to run and sometimes itch, including the mouth. Sometimes you may also develop an itchy rash on your skin, called hives. Antihistamines lessen or block histamines (a symptom-causing chemical released by your immune system during an allergic reaction), so they can stop allergy symptoms.

Antihistamines perform very well to relieve symptoms of diverse types of allergies, including seasonal hay fever and both indoor and food allergies, but they automatically cannot relieve every symptom. Your doctor may recommend taking a decongestant to treat nasal congestion because some drugs are combined with an antihistamine and decongestant.

Antihistamines come in various forms such as tablets, liquids, nasal sprays, eye-drop, and capsules. Some of these allergy medications are prescribed while others can be bought over the counter (OTC) at your local pharmacy.

Tablets, Capsules and Liquids

Because some of these allergy medications can cause drowsiness and tiredness, they should not be taken when driving or performing any potentially dangerous activities. Oral antihistamines are available as over-the-counter medications and prescription drugs. However, these allergy medications ease itchy or watery eyes, hives, runny nose, swelling, and any other signs or symptoms of allergies.

Antihistamines medications that causes drowsiness include:

  • Diphenhydramine(Benadryl)
  • Chlorpheniramine

The antihistamines below are less likely to cause drowsiness:

  • Cetirizine (Zyrtec)
  • Loratadine (Alavert, Claritin)
  • Desloratadine(Clarinex)
  • Levocetirizine(Xyzal)
  • Fexofenadine(Allegra)

Nasal sprays

Antihistamine nasal sprays relieve sneezing, sinus congestion, itchy or runny nose and postnasal drip. The side effects of antihistamine nasal sprays may include a feeling of bitter taste, drowsiness or fatigue. Prescribed antihistamine nasal sprays include:

  • Allergy Medications and Nasal SprayOlopatadine (Patanase)
  • Budesonide (Rhinocort Aqua)
  • Fluticasone furoate (Veramyst)
  • Fluticasonepropionate(Flonase)
  • Azelastine (Astelin, Astepro)
  • Mometasone (Nasonex)

Eye-drops

Antihistamine eye-drops bring soothing ielief to the itching eyes and readily available as over-the-counter
or prescription medications. These drops may have a combination of antihistamines and other related medicines. The side effects may sometimes include headache and dry eyes. If antihistamine drops a sting or burn, try to keep them in the icebox or use cooled artificial-tear drops before you use the medicated drops. Examples of antihistamine eye-drops include:

  • Azelastine (Optivar)
  • Ketotifen (Alaway, Zaditor)
  • Olopatadine (Pataday, Patanol)
  • Emedastine (Emadine)
  • Pheniramine (Visine-A, Opcon-A, others)

Decongestants

Decongestants are used for quick and temporary relief of nasal and sinus congestion. The side effect can range from insomnia, headache, and increased blood pressure to inflammation. These types of medications are not always recommended for who pregnant women or for people with high blood pressure, glaucoma or hyperthyroidism, and cardiovascular disease.

Best Allergy Medication

Zyrtec and Claritin

Zyrtec contain cetirizine which is a non-sedating antihistamine as the active ingredient while Loratadine is the active ingredient in Claritin which is a non-sedating antihistamine is as well. These newly emerged allergy relief medicines are mostly preferred over the old allergy-relieving medications which regularly made people very drowsy and tired. However, some people using these types of medication may still experience drowsiness especially the users of Zyrtec. Zyrtec and Claritin medication may be very useful to people suffering from seasonal allergies (itchy eyes, runny nose, sneezing).

People who experience congestion may look for versions of these medicines that contain a decongestant. These medications are often marked with a “D” at the end of the medicine brand name. Claritin-D and Zyrtec-D, for example, contain a decongestant medication called pseudoephedrine. In some cases, products containing pseudoephedrine must be allowed to be prescribed by your doctor. You must talk with your doctor or pharmacist before taking Zyrtec-D or Claritin-D. This pseudoephedrine (decongestant) can raise the blood pressure and put extra tension on the kidneys. Decongestants like pseudoephedrine are also referred to as stimulants and can keep you awake at night. Children may be particularly sensitive to this effect.

Allergy medicationsZyrtec and Claritin are members of a class of substances called antihistamines. These medications are made in a way to bring calmness to the histamine reaction your body has when the cells are exposed to an allergen. The body sends out white blood cells and goes into fight mode when it encounters something to which it is allergic to producing a substance called histamine. The receptors for histamine are situated in the nose and all breathing passages, but they are similarly situated in the brain. This is mostly why antihistamines, which attack the action of histamine can have an effect on vigilance and makes you feel drowsy. These newly developed antihistamines are much less likely to cause that side effect.

Zyrtec is available in various forms and dose:

  • 10 mg of solid tablets
  • 5 mg and L0 mg of flavoured chewable tablets
  • 10 mg of dissolving tablets
  • 5 mg/ml of syrup and oral solution
  • 1 mg/mL of syrup oral solution.

The age and severity of symptoms depend on the amount of dose for Zyrtec. The daily dose for adults is should not exceed 5 mg or 10 mg. Adults who have chronic illness should take 5 mg or meet with their doctor before taking the product since it has more likelihood for sedation than Claritin. There is a wide variety of Zyrtec product to make it easier to give the right dose, so children can be given Zyrtec and don’t forget that children also differ in sizes and ages, so when in doubt start with a smaller dose. To achieve the best possible results, it is advisable you see your child’s doctor or a pharmacist before deciding on the dose to give your child and also check the package for dosing guidelines.

Forms and Dosing for Claritin

Claritin is available in many forms:

  • 10 mg solid tablets
  • 5 mg chewable tablets
  • 10 mg dissolving tablets
  • 5 mg/ml oral solution
  • 5 mg/ml oral syrup

The dose for both Zyrtec and Claritin depends largely on the severity of your symptoms and age. The day-to-day adult dose of Claritin is 10 mg per day, but some people may take 5 mg twice a day instead. Claritin is very active in the body for at least 24 hours.

The daily children dose of Claritin 5 mg, given once a day. There are various dose forms, including spiced syrups and solutions, chewable tablets to make it easier for your child to use.

Efficiency

Both Zyrtec and Claritin are more efficient at relieving symptoms of an allergy. In a comparative study, Zyrtec was found to be fast active medication than Claritin.
