#2: You Aren't Consistent With Your Medication Take one Claritin every day for it to be the most effective, but don't take more than one pill a day, even if you missed a pill the day before. Taking multiple pills a day increases your risk of serious side effects.
What happens if I take more than one dose of Claritin®? Taking more than the recommended dose of Claritin® may cause drowsiness. In the case of overdose, get medical help or contact a Poison Control Center right away- always follow label directions.
Do not take more than one dose in 24 hours. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Common medications like Zyrtec, Allegra, Flonase, and Claritin don't usually stop working. It's time to check for new allergies if your nose is still stuffy and you can't stop sneezing after taking your regular allergy medicine. You may need a new treatment plan, not just more medication.
Loratadine is generally very safe. If you or your child take too much, it is unlikely to harm you.
Even if you're severely suffering from allergies, with incredibly watery eyes or a scratchy throat, it's not recommended to take more than the daily dosage as there can be side effects that occur.
If a healthy adult takes only a slightly higher dose of antihistamine, such as accidentally taking two pills instead of one, their symptoms may not be serious, or they may not have any symptoms. However, a larger overdose, especially in children or older adults, may cause serious symptoms.
Why do antihistamines stop working? Antihistamines can stop working because your allergies might be getting worse or you might have immune system changes due to aging. You also might not be taking the medication as directed. If you take an antihistamine after being exposed to an allergy trigger, it won't work as well.
Sometimes, despite aggressive allergy treatment, nasal congestion persists. It's possible that the culprit is sinusitis. Sinusitis, not to be confused with rhinitis, is characterized by inflammation of the nasal passages and sinuses. Swelling can cause sinus drainage passages to become blocked and mucus to accumulate.
Can you take Zyrtec and Claritin the same day? While you shouldn't take Zyrtec and Claritin at the same time, you may be able to take Zyrtec and Claritin on the same day, depending on when you took your last dose. For instance, Claritin comes in both 12-hour and 24-hour tablets.
“Zyrtec is found to be more potent, or stronger, in laboratory studies, compared with Claritin,” says Dr. Kung. “It also reaches a higher concentration in the skin, which can be more helpful for skin-related allergies. However, Zyrtec has a greater chance of making you sleepy while taking it.”
Taking more than the usual dose is unlikely to harm you or your child. If you take an extra dose, you might get some of the common side effects. If this happens or you're concerned, contact your doctor.
Antihistamines are used to relieve or prevent the symptoms of your medical problem. Take them only as directed. Do not take more of them and do not take them more often than recommended on the label, unless otherwise directed by your doctor. To do so may increase the chance of side effects.

If there is no histamine, then antihistamines can't relieve symptoms. If antihistamines aren't working for you and you have allergy-like symptoms, it may not be a bad allergy season—but instead something non-allergic you're reacting to. Symptoms of nonallergic rhinitis include: Sneezing.

In general, an oral antihistamine tablet will start to work within 30 minutes and reach its maximum effect in about 2 hours. You will know when an antihistamine starts to work when it starts to relieve allergy symptoms, such as congestion, runny nose, itchy eyes or skin rash.
