Allergy and Zyrtec information

Spring is the time for many people to suffer from the symptoms of seasonal allergies. The plants and flowers produce pollen and it can be easily inhaled by people. The pollen can be a severe allergen for people with allergies such as hay fever.

These allergic people start sneezing, cough, cannot breathe properly because of nasal congestion or runny nose, they can also suffer from itchy and runny eyes.

The immune system of an allergic person immediately reacts to the allergens by releasing histamine and attacking the allergens. This causes swelling, irritation of the nasal mucosa, and other symptoms.

There is a need to visit a doctor if you have symptoms of seasonal allergy. General practitioner can refer you to an allergist for special tests like skin tests or blood tests.

The treatment usually demands taking certain medicines and avoiding triggers of the allergies. Nasal sprays, eye drops and tablets can be recommended as various forms of medications used to prevent allergy symptoms and treat them.

Sometimes the treatment with drugs that combine two components is recommended. They relieve congestion, clear the nasal passages, decrease swelling, improve other symptoms.

Most allergic medicines are available without prescription. Still you should not use them without control. A doctor’s advice is always required.

Antihistamines are common medicines which are prescribed for the treatment of allergies. They are classified as first, second and third generation medicines. The newest medicines are characterized by fewer side effects associated with antihistamine use such as dizziness, sleepiness, drowsiness.

Today the antihistamine medicines can be taken once a day and this is a very convenient way of application.

Zyrtec (Cetirizine) is one of the medicines for the treatment of allergies available without prescription. It effectively reduces the symptoms of hay fever, sneezing, skin itching, coughing, swelling, watery eyes, runny nose.

Zyrtec comes in comfortable forms which can be useful for different categories of patients: tablets, chewable tablets, and syrup. This medicine is approved by the FDA as a safe and effective antihistamine.

Zyrtec use should be discussed with your doctor if you use other medicines including antihistamines, if you have liver or kidney problems.

Zyrtec treats allergies but can cause allergic reactions itself. So, if you experience allergic reactions to Zyrtec, it is necessary to stop taking it and consult your doctor.

This medicine is usually well-tolerated and does not cause sleepiness, still in some patients it may cause impaired thinking or reactions due to drowsiness. Such patients should be careful especially if they drive or operate other tasks demanding being alert.

Drinking alcohol can increase certain side effects of Zyrtec. It should not be mixed with alcoholic beverages.

Though Zyrtec is not expected to be harmful to an unborn baby, its application should be discussed with a doctor.

Zyrtec can pass into breast milk and may harm the baby, so a woman who is breast-feeding should not apply Zyrtec for her allergies.

Many drugs can interact with Zyrtec, especially medicines which can increase sleepiness. So, medicines like cold pills, pain relievers and other causing drowsiness should not be taken together with Zyrtec.

Testimonials about different drugs

hohmodrom_impotenceI took this drug several times and the effect was above all my expectations! For the first time I took 60 mg dose and I got severe headache. The result was as promised – no premature ejaculation and the possibility to have a real good sex. I could wait until my wife came, and then I ejaculated. But the next day I had headache. So for the next time I reduced the dose for half and took only 30 mg, and wonderful! I didn`t have any headache. In sex the results were OK too but frankly speaking I need more concentration for the ejaculation.
