Zyrtec, while generally safe, can cause side effects in some people. These are usually mild and temporary.
- Drowsiness: This is the most common side effect. Avoid driving or operating machinery if you feel sleepy. Dry mouth: Drink plenty of water. Headache: Over-the-counter pain relievers may help. If headaches are severe or persistent, contact your doctor. Nausea: Take Zyrtec with food to minimize this. Fatigue: This can vary in intensity. Rest when needed.
Rare, but more serious, side effects include fast heartbeat, seizures, and allergic reactions. Seek immediate medical attention if you experience any of these.
Before taking Zyrtec:
Inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements. Certain interactions are possible. Discuss your medical history, especially if you have kidney or liver problems, heart conditions, or a history of seizures. Consult your doctor before using Zyrtec if you are pregnant, breastfeeding, or planning to become pregnant. Follow the dosage instructions carefully. Do not exceed the recommended dose.
If side effects are bothersome or persistent, talk to your doctor or pharmacist. They can advise on management or alternative allergy treatments.
