Avoid the use of alcohol, sedatives, and tranquilizers as cetirizine can increase the risk of drowsiness. Cetirizine may cause central nervous system depression; avoid activities requiring mental alertness until accustomed to the medication. See "What Are Side Effects Associated with Using Cetirizine?"
Do not use with any other antihistamines applied to the skin (such as diphenhydramine cream, ointment, spray) because increased side effects may occur. Cetirizine is very similar to hydroxyzine and levocetirizine. Do not use these medications while using cetirizine.
The antihistamine in this medicine will add to the effects of alcohol and other CNS depressants including tricyclic antidepressants (medicines that slow down the nervous system, possibly causing drowsiness).
It's fine to take cetirizine in combination with other forms of medicine for hay fever, for example nasal sprays, such as Beconase or eye drops such as Opticrom. However, you should not take other medicines containing antihistamines in combination with cetirizine.
CETIRIZINE+PARACETAMOL+PHENYLEPHRINE should be taken as prescribed by the doctor. Your doctor will recommend how often you take CETIRIZINE+PARACETAMOL+PHENYLEPHRINE based on your medical condition. Some people may experience drowsiness, nausea, fatigue, dryness in the mouth, headache, and vomiting.
Cetirizine is an antihistamine medication that treats allergy symptoms like itchy eyes, sneezing, a stuffy nose or hives. A common brand name for this medication is Zyrtec®.
Oral antihistamines, such as Zyrtec and Benadryl, shouldn't be taken together without a healthcare provider's OK. Taking oral antihistamines together can lead to additional side effects and potentially an antihistamine overdose. Signs of an overdose may include the following: Fast or racing heartbeat.
Common side effects include headaches, dry mouth, feeling sick, dizziness and diarrhoea. Some brands of cetirizine come as capsules. These may contain soya oil. Do not take cetirizine capsules if you are allergic to peanuts or soya.
Claritin and Zyrtec are effective and safe for most people with minor allergies.
Official answer. Cetirizine can be taken at any time of the day. In most people it is non-sedating, so they take it in the morning. However, a percentage of people do find it to be sedating so if it does make you drowsy it is best to take it in the evening.
Cetirizine reaches peak plasma concentration after approximately one hour. Its effects typically begin after 20 to 60 minutes and persist for at least 24 hours. Food does not affect the extent of exposure (AUC) of cetirizine, but the time to attain peak concentration is delayed by 1.7 hours.
Sandoz issued a voluntary recall of 1,023,430 units of Zyrtec (10 mg) capsules as a result of failed impurities and a specification being reported for impurity at the 21-month stability time point, according to an FDA Enforcement Report.
This leads to clearing of nasal congestion, but it may also cause an increase in blood pressure in patients who have high blood pressure.
Alcohol can increase the nervous system side effects of cetirizine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with cetirizine.
No interactions were found between cetirizine and Vitamin C.
One study of 92 people with chronic itchiness saw that patients who took the antihistamines cetirizine and hydroxyzine reported an increase in depression and anxiety.
Based on pre-clinical and clinical evidence, it appears that loratadine, cetirizine, and fexofenadine are safe from cardiac arrhythmia via the IKr channel, whereas astemizole and terfenadine have a propensity to cause ventricular tachyarrhythmias.
Zyrtec (cetirizine) is the strongest of the second-generation antihistamines, says Dr. Garcia-Ibáñez. And because there is less chance of toxicity with this medication, the dosage can be increased substantially, at the discretion of your doctor, he says. Zyrtec is an effective treatment for allergy symptoms and hives.

This is a therapeutic duplication and it is usually recommended to take only one antihistamine at any time, however if you have been prescribed to take both together then it is appropriate. If you do experience any odd symptoms please see your doctor.
Cetirizine, a metabolite of hydroxyzine, is an antihistamine with as distinguishing features: 1) exquisite anti-H1 specificity: cetirizine appears unique in being devoid of action on receptors other than the H1 receptor; 2) potency: at unit dose it is the most potent antihistamine in the skin and the lung; 3) absence ...
“Zyrtec is found to be more potent, or stronger, in laboratory studies, compared with Claritin,” says Dr. Kung. “It also reaches a higher concentration in the skin, which can be more helpful for skin-related allergies. However, Zyrtec has a greater chance of making you sleepy while taking it.”
