Acute urticaria in adults and children older than 6 months can be treated with cetirizine injection. Cetirizine belongs to the group of drugs known as antihistamines. It functions by inhibiting the body’s production of histamine, which is responsible for the symptoms of allergies.

Cetirizine is available as an intravenous solution (liquid) (into the vein). Normally, it is administered once per 24 hours as necessary. Use cetirizine as prescribed. Never take it in amounts or frequencies other than those specified on the package label or as advised by your doctor.

Cetirizine injections can be administered either in a hospital setting or at home. Your doctor will instruct you on how to administer cetirizine injection if you plan to do so at home. Make sure you comprehend these instructions, and if you have any issues, consult your healthcare professional.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

Before taking cetirizine,

• If you have any allergies to any medications, including cetirizine, levocetirizine, hydroxyzine (Vistaril), or any of the ingredients in cetirizine injection, notify your doctor and pharmacist right away.
• While using cetirizine, be sure to let your doctor and pharmacist know what prescription and over-the-counter drugs, vitamins, herbal items, and nutritional supplements you are currently taking or intend to use. Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.
• If you have kidney or liver problems now or in the past, let your doctor know.
• Inform your doctor if you are expecting, intend to get pregnant, or are nursing a baby. Call your doctor if you become pregnant while taking cetirizine.
• You need to be aware that cetirizine might make you sleepy. Prior to understanding how this drug affects you, avoid using machinery or driving a car.
• Keep in mind that drinking alcohol can worsen the drowsiness brought on by this drug. While using this medication, refrain from drinking alcoholic beverages.

Keep eating normally unless your doctor instructs you otherwise.

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at http://goo.gl/c4Rm4p for additional information.

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Moreover, information can be found online at https://www.poisonhelp.org/help. Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

Overdose symptoms could include:

• Fatigue
• Drowsiness

Keep all of your doctor’s appointments.

Ask any queries you may have regarding cetirizine to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
