You may choose to take ZYRTEC by mouth with a meal to avoid an upset stomach or without one.
Drug Class and Mechanism
ZYRTEC falls under antihistamine and it works by blocking the action of histamine and reduces the symptoms of an allergic reaction.
Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
Store ZYRTEC at room temperature 20-25 degrees C(68-77 degrees F). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.
Doctors advise against using ZYRTEC if you are allergic to any ingredient in it or to hydroxyzine.
Discuss your past/current medical history in detail with your doctor before beginning treatment with any new medication. If you are using any herbal supplements or over the counter medication, including vitamin pills, then mention it to your doctor.
Your condition might be monitored or the dosage might be modified to suit you if you have conditions like kidney or liver problems, or are receiving dialysis.
If you are expecting a child or are planning to have a child in the near future, then consult your doctor before using ZYRTEC to discuss any possible threats to the unborn baby.
If you are a nursing mother and breast feed your baby, then too, seek consultation before using ZYRTEC as some drugs are excreted in the breast milk and may enter the baby.
