Things You'll Need:
- Prescription for Zyrtec
-
Step 1
Visit your doctor to discuss your allergies and get a prescription for Zyrtec. The adult form of the medication is available as tablets, chewables or a syrup. Children from 6 months of age and older can take Zyrtec syrup and the chewable tablets are approved for children older than 2 years old.
-
Step 2
Ask your doctor for a prescription for Zyrtec-D if you need a decongestant in addition to the antihistamine in order to combat your allergies. This is an extended-release form of the drug that is effective for 12 hours.
-
Step 3
Follow the dosage instructions exactly as they are written. Some forms of Zyrtec are taken once daily, while others can be split up and taken twice a day. Ask your doctor or pharmacist questions about the dosage if you have any doubt about it.
-
Step 4
Put your Zyrtec in a closed cabinet or on high shelf, where animals and children cannot reach it. Keep it away from light, heat and moisture to maintain the effectiveness of the drug.
-
Step 5
Avoid taking doses of Zyrtec too close together. If you forget a dose, take it when you remember it. If it is almost time to take another dose, take a single dose rather than doubling up on the medication.
-
Step 6
Inform yourself about the side effects of Zyrtec. You may experience a dry mouth, dizziness, fatigue or stomach pain when first starting the medication. After your body adjusts to the drug, side effects generally lessen or disappear completely.
