How much Zyrtec should adults take. What is the correct Zyrtec dosage for children. Are there different dosing recommendations for various Zyrtec products. What factors affect Zyrtec dosing.

Understanding Zyrtec and Its Active Ingredient Cetirizine

Zyrtec is a popular over-the-counter antihistamine medication used to treat allergy symptoms. Its active ingredient, cetirizine hydrochloride, works by blocking histamine receptors in the body, thereby reducing allergic reactions. Zyrtec is available in various forms, including tablets, chewable tablets, and liquid syrup, catering to different age groups and preferences.

Cetirizine belongs to the second-generation antihistamine class, known for causing less drowsiness compared to first-generation antihistamines. This makes Zyrtec a preferred choice for many allergy sufferers who need relief without significant sedation.

How does Zyrtec work?

Zyrtec works by selectively inhibiting peripheral H1 receptors, which are responsible for allergic symptoms. By blocking these receptors, cetirizine prevents histamine from binding to them, thus reducing allergy symptoms such as sneezing, runny nose, itchy eyes, and skin reactions.

Zyrtec Dosing for Adults: Guidelines and Recommendations

For adults under 65 years of age, the recommended Zyrtec dosage is generally 10 mg once daily. This can be taken as one 10 mg tablet, two 5 mg tablets, or 10 mL of syrup. In some cases, particularly for less severe symptoms, a 5 mg dose may be sufficient.

• Standard adult dose: 10 mg once daily
• Maximum daily dose: 10 mg
• For milder symptoms: 5 mg may be appropriate

Adults aged 65 and over should consult a doctor before taking Zyrtec, as dosing may need to be adjusted based on individual health factors.

Can adults take Zyrtec with food?

Yes, adults can take Zyrtec with or without food. The medication’s absorption is not significantly affected by food intake, making it a convenient option for those with varying schedules or dietary habits.

Zyrtec Dosing for Children: Age-Specific Guidelines

Zyrtec dosing for children varies based on age and product formulation. It’s crucial to follow the recommended dosages to ensure safety and efficacy.

Children 6 to 11 years old

For children aged 6 to 11 years, the recommended Zyrtec dosage ranges from 5 mg to 10 mg once daily, depending on symptom severity. This can be administered as:

• One 5 mg or 10 mg tablet
• 5 mL or 10 mL of syrup
• One 5 mg or 10 mg chewable tablet

Children 2 to 5 years old

For children aged 2 to 5 years, the initial recommended dose is 2.5 mL (½ teaspoon) of syrup once daily. If needed, this can be increased to:

• 2.5 mL (½ teaspoon) of syrup every 12 hours
• One 5 mg chewable tablet once daily

Children under 2 years old

For children under 2 years of age, it’s essential to consult a doctor before administering Zyrtec. The dosing for this age group is more specific and requires professional guidance.

Special Considerations for Zyrtec Dosing

While Zyrtec is generally safe for most people, certain groups may require special considerations when it comes to dosing.

Patients with liver or kidney disease

Individuals with liver or kidney disease should consult a doctor before taking Zyrtec. These conditions can affect how the body processes and eliminates the medication, potentially requiring dosage adjustments.

Elderly patients (65 years and older)

Older adults may be more sensitive to the effects of Zyrtec and may require lower doses. It’s recommended that patients 65 years and older consult with a healthcare provider to determine the appropriate dosage.

Frequently Asked Questions About Zyrtec Dosing

Here are some common questions people have about Zyrtec dosing:

Can I take more than the recommended dose of Zyrtec?

No, it’s not recommended to exceed the prescribed dosage of Zyrtec. Taking more than the recommended dose doesn’t increase its effectiveness and may lead to increased side effects. Always follow the dosing instructions provided by your healthcare provider or on the product label.

How long does it take for Zyrtec to start working?

Zyrtec typically begins to work within an hour of taking the medication. However, the full effects may not be noticeable until after a few days of consistent use.

Can I take Zyrtec long-term?

Zyrtec is generally safe for long-term use in most people. However, if you find yourself needing to take it regularly for an extended period, it’s best to consult with your healthcare provider to ensure it’s the most appropriate treatment for your condition.

Is it safe to take Zyrtec with other medications?

While Zyrtec is generally safe to take with most medications, it’s always best to consult with your healthcare provider or pharmacist about potential drug interactions. Certain medications, particularly those that cause drowsiness, may interact with Zyrtec.

Comparing Zyrtec to Other Antihistamines

Zyrtec is one of several second-generation antihistamines available over the counter. Understanding how it compares to other options can help in making an informed choice.

Zyrtec vs. Claritin

Both Zyrtec (cetirizine) and Claritin (loratadine) are effective antihistamines, but they may work differently for different people:

• Zyrtec may provide faster relief but is more likely to cause drowsiness
• Claritin may take longer to take effect but is less likely to cause drowsiness
• Both are typically taken once daily

Zyrtec vs. Allegra

Zyrtec and Allegra (fexofenadine) are both effective antihistamines with some differences:

• Zyrtec may be more effective for some people but has a higher chance of causing drowsiness
• Allegra is less likely to cause drowsiness and may be preferred by those who are sensitive to sedating effects
• Allegra’s absorption can be affected by certain fruit juices, while Zyrtec is not affected by food

The choice between these antihistamines often comes down to individual response and tolerance. It’s worth noting that some people may find one more effective than others, so it may take some trial and error to find the best option.

Tips for Maximizing Zyrtec’s Effectiveness

To get the most out of your Zyrtec treatment, consider the following tips:

1. Take Zyrtec at the same time each day to maintain consistent levels in your body
2. For seasonal allergies, start taking Zyrtec before the allergy season begins
3. Be patient – it may take a few days of regular use to experience the full benefits
4. Combine Zyrtec with other allergy management strategies, such as avoiding triggers and using nasal sprays when recommended
5. Stay hydrated, as antihistamines can have a mild dehydrating effect
6. If drowsiness occurs, consider taking Zyrtec in the evening

Remember, while Zyrtec can be highly effective in managing allergy symptoms, it’s always best to consult with a healthcare professional for personalized advice, especially if you have ongoing or severe allergy issues.

Generic name: cetirizine hydrochloride
Dosage form: tablets, chewable tablets, syrup
Drug class: Antihistamines

Medically reviewed by Drugs.com. Last updated on Sep 26, 2022.

ZYRTEC can be taken without regard to food consumption. ZYRTEC is available as 5 mg and 10 mg tablets, 1 mg/mL syrup, and 5 mg and 10 mg chewable tablets which can be taken with or without water.

Adults and Children 12 Years and Older

The recommended initial dose of ZYRTEC is 5 mg or 10 mg per day in adults and children 12 years and older, depending on symptom severity. Most patients in clinical trials started at 10 mg. ZYRTEC is given as a single daily dose. The time of administration may be varied to suit individual patient needs.

Children 6 to 11 Years

The recommended initial dose of ZYRTEC in children aged 6 to 11 years is 5 mg or 10 mg once daily depending on symptom severity. The time of administration may be varied to suit individual patient needs.

Children 2 to 5 Years

The recommended initial dose of ZYRTEC in children aged 2 to 5 years is 2.5 mg (½ teaspoon) syrup once daily. The dosage in this age group can be increased to a maximum dose of 5 mg per day given as 1 teaspoon syrup once a day or one ½ teaspoon syrup given every 12 hours, or one 5 mg chewable tablet once a day.

Children 6 months to <2 years

The recommended dose of ZYRTEC syrup in children 6 months to 23 months of age is 2.5 mg (½ teaspoon) once daily. The dose in children 12 to 23 months of age can be increased to a maximum dose of 5 mg per day, given as ½ teaspoon (2. 5 mg) every 12 hours. Syrup is recommended for children under the age of 2 years.

Dose Adjustment for Renal and Hepatic Impairment

In patients 12 years of age and older with decreased renal function (creatinine clearance 11–31 mL/min), patients on hemodialysis (creatinine clearance less than 7 mL/min), and in hepatically impaired patients, a dose of 5 mg once daily is recommended. Similarly, pediatric patients aged 6 to 11 years with impaired renal or hepatic function should use the lower recommended dose. Because of the difficulty in reliably administering doses of less than 2.5 mg (½ teaspoon) of ZYRTEC syrup and in the absence of pharmacokinetic and safety information for cetirizine in children below the age of 6 years with impaired renal or hepatic function, its use in this impaired patient population is not recommended.

Dose Adjustment for Geriatric Patients

In patients 77 years of age and older, a dose of 5 mg once daily is recommended.

Allergic rhinitis is a disease accompanied by itching in the nasal cavity, endless watery discharge from the nose, paroxysmal sneezing and absolute nasal congestion. And such symptoms appear with the beginning of flowering plants. It’s all about the reaction of the body to irritating factors from the outside. In the case of allergic rhinitis, this is plant pollen.

During this period, people suffering from this disease are helped by antihistamines. One of them is Zyrtec. We asked pharmacist Kristina Khokhrina to tell us more about it, and this is what she told us: what it is used for, what is included in the composition of the product, in what dosage it is used and whether it is suitable for children. We also provided a small list of similar antihistamines and found differences between Zirtek and Zodak, Citrine and Erius.

Zyrtec: what

Zyrtec is used for for allergies. The main indications for the use of Zirtek:

• allergic rhinitis
• allergic conjunctivitis
• symptoms of chronic urticaria

The drug acts on the skin one hour after ingestion. Maximum efficiency is achieved within 2-12 hours. The effect gradually decreases, but persists for a day.

Zyrtec: active ingredient

Zyrtec: composition

Zyrtec is available in two forms: drops and tablets. Let’s talk about the composition of both drugs. The active substance in both forms is the same, only the auxiliary components change, since they determine the form of the drug.

Zyrtec drops: glycerol, propylene glycol, sodium saccharinate, methylparabenzene, propylparabenzene, sodium acetate, glacial acetic acid, purified water.

Zyrtec tablets: microcrystalline cellulose, lactose monohydrate, colloidal silicon dioxide, magnesium stearate, hypromellose, titanium dioxide, macrogol.

Zyrtec: dosage

The dosage of Zyrtec is determined by the amount of active ingredient per 1 ml drops or 1 tablet. In both cases, cetirizine is contained in a dosage of 10 mg.

The drug is prescribed for adults and children from 6 months. For each age, a certain dose is established. The manufacturer recommends taking Zirtek in the evening, as the symptoms of allergic diseases are most pronounced at night. It is taken with or without food and can be taken with water as needed.

Adults are advised to take 20 drops or 1 tablet once a day, which corresponds to a dosage of the substance 10 mg. Reception Zirtek in drops can be single in the evening or divided into 2 doses. For example, 10 drops in the morning and evening.

Zyrtec side effects

Zyrtec may rarely cause the following side effects:

• general fatigue
• dizziness
• headache
• abdominal pain
• dry mouth
• nausea
• drowsiness

Children may additionally develop diarrhea. When taking medication, pay attention to your condition. If any changes appear, described or not described in the instructions, or if allergy symptoms increase, consult a doctor.

Zyrtec Drops for Children

Zyrtec should only be used in children aged 6 to 12 months on prescription and under the supervision of a physician. The drug is prescribed depending on age:

• 6 to 12 months: Take 5 drops (2.5 mg) once a day
• 1 to 6 years: Take 5 drops (2.5 mg) twice a day in the morning and evening, or 10 drops (5 mg) once a day in the evening
• 6 to 12 years: Take 20 drops (10 mg) once daily
• over 12 years old: take 20 drops (10 mg) once a day

Zyrtec may be used during pregnancy after consulting a physician only if the intended benefit to the mother outweighs the potential risk to the fetus. The same applies to use during lactation, since cetirizine passes into the mother’s breast milk.

Zyrtec: analogues

Zyrtec is one of the representatives of the group of antihistamines. Its analogues contain the same active ingredient: cetirizine:

• Cetirizine
• Zincette
• Zodak
• Cetrin
• Sensor
• Soloneks

Preparations with a different composition, for example, Erius, can also be analogues of Zirtek. Let’s compare Zodak with some of the remedies from this list.

Zyrtec or Zodak: which is better

The preparations have the same active substance, which defines them as antiallergic agents. Indications for use, dosage of the active substance, side effects and other characteristics of Zirtek and Zodak are the same.

The drugs are as similar as possible and even have the same forms of release: drops and tablets. The only difference is the manufacturers. Zyrtec is made in Switzerland, and Zodak is made in Russia, which is reflected in the price of the funds. Therefore, when choosing what is better to buy: Zodak or Zirtek, be guided by your preference, since the drugs are identical in terms of effectiveness.

Zyrtec or Cetrin: which is better

Similar to Zyrtec, Cetrin contains the same active ingredient in the same dosage of tofu. According to their characteristics, the preparations are identical, except that only Cetrin’s indications are slightly wider. It is additionally used for:

• itching allergic dermatoses: atopic dermatitis, etc.
• angioedema angioedema

Cetrin is available in tablet form only and is indicated for use in adults and children over 6 years of age, just like Zyrtec tablets. Manufacturers of drugs are also different, Citrine is produced in India. When choosing products, pay attention to the age of the patient and your preference in the manufacturer.

Zirtek or Erius: what is better

Zirtek and Erius are drugs for allergic manifestations. Their most important difference is the active substance.

Erius – contains desloratadine. It is produced in the form of tablets and syrup. The dosage of the active substance is 5 mg per 1 tablet and 0.5 mg per 1 ml of syrup. Erius is used by adults and children from 12 years old, and syrup can be given from 1 year old. The use of Erius does not adversely affect driving.

The method of administration depends on the age of the patient. Of course, manufacturers also differ: Erius is a Belgian drug.

Zyrtec – contains cetirizine. There are much more contraindications for use than Erius. Caution should be exercised when driving vehicles, as cetirizine causes drowsiness.

Thus, when choosing an antihistamine Erius or Zodak, pay attention to the list of contraindications and side effects. Especially if your activity is connected with increased concentration of attention.

Summary

• Zyrtec is an antihistamine that is used to eliminate allergic reactions in allergic rhinitis and conjunctivitis, as well as urticaria.
