Zyrtec to Block Histamine Effect

Zyrtec, also known as Cetirizine, belongs to a group of antihistamines that are potent to decrease the effect of naturally produced histamine in the organism. Histamine is the body chemical that can produce numerous undesirable symptoms, including watery eyes, sneezing, runny nose, itching and others. Zyrtec, in its turn, is aimed at blocking the action of the chemical and eliminating possible allergy or flu symptoms. Additionally, the drug is used to improve swelling and itching caused by hives (chronic urticaria). Your doctor may recommend Zyrtec for other uses, not mentioned in the safety guide.

Vital Information to Consider before Zyrtec Use

Taking Zyrtec without previous doctor’s consultation you risk getting devastating side effects and dangerous condition aggravation. Ask your doctor if you can take the medication safely. Provide the specialist with a complete list of health problems you have. Do not administer the drug in case you are allergic to its active ingredient Cetirizine or similar remedies.

Pregnant and breastfeeding women should avoid medication use to prevent their children from possible Zyrtec effect. Thus, inform your doctor if you are breastfeeding, pregnant or plan to become such.

As any other powerful treatment, Zyrtec can lead to severe complications if combined with other drugs. Tell your doctor about other prescription and non-prescription medicines, herbal products and other supplements you are using to decrease the risk of possible drug interactions. Definite pharmaceuticals combined with Zyrtec can make you extremely sleepy. They include the following:

In case you have missed one dose, take Zyrtec pill as fast as possible, but skip if the following scheduled one should be taken in a short while. Never increase or double the next dose to avoid overuse.

Possible Zyrtec Side Effects
