What happens if I take 2 loratadine? ›

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. See individual product pages for label directions.

You may only need to take loratadine on a day when you have symptoms, for instance if you've been exposed to a trigger such as animal hair. Or you may need to take it regularly to prevent symptoms, such as hay fever during spring and summer. Try to take loratadine at about the same time every day.

Patients should not take loratadine with other CNS depressants such as diphenhydramine, dextromethorphan, or pseudoephedrine as it may cause dose-related sedation. There is no evidence for increased adverse events when combining loratadine and oral contraceptives.

Decongestants: These offer the fastest relief. Nasal spray options should work within about 10 minutes, and oral options work within 30 to 60 minutes. Oral antihistamines: These are another quick-relief option. Many work within about 1 to 2 hours.

No, with loratadine tablets, you should not take a 5-milligram (mg) or 20-mg dose. The maximum recommended dosage of loratadine is 10 mg in 24 hours. Taking a higher dose of loratadine, such as 20 mg, may cause an antihistamine overdose or increase your risk of side effects.

Combining two or more oral antihistamines can lead to additional side effects and potentially an antihistamine overdose. Signs of an overdose may include the following: Fast or racing heartbeat. Dry mouth.

You can take it at any time of the day, morning or night. You can have it with or without food. Food or time do not affect the efficacy of this medicine.

Non-drowsy options like loratadine and cetirizine are among the safest choices for long-term allergy relief. Both medications work by blocking the effects of histamine, and people generally tolerate them well.

Zyrtec. Zyrtec (cetirizine) is the strongest of the second-generation antihistamines, says Dr. Garcia-Ibáñez. And because there is less chance of toxicity with this medication, the dosage can be increased substantially, at the discretion of your doctor, he says.

Hepatotoxicity. Loratadine and desloratadine use are associated with a low rate of liver enzyme elevations which are usually asymptomatic, mild and self-limited even without modification of the dose.

Is loratadine safe for the heart? ›

Cardiac Arrythmia Risk.

Newer antihistamines like fexofenadine, ceterizine and loratadine are all fairly safe for the heart, with fexofenadine seeming to be the absolute safest if you are at risk of arrythmia.

Some of the most serious side effects of loratadine require daily use over weeks and months to become a problem. Though rare, delayed side effects include seizures, liver problems, blood clotting problems, constipation, and weight gain.

Astepro (azelastine) nasal spray, and non-drowsy oral antihistamines, such as Allegra (fexofenadine) are also first-choice options. All of these allergy medications are safe for older adults. Nasalcrom (cromolyn) and antihistamine eye drops, such as Zatidor (ketotifen), are also safe but may be less effective.

Allergies happen when your body's immune system reacts to certain substances as though they are harmful. Allergy symptoms may not go away unless you avoid your triggers, stick to your medications, find the right combination of medications, and consider surgery.

Allergists recommend long-acting, non-sedating antihistamines — ones that won't make you sleepy — for everyday use. Though you may know them by their brand names, the generic versions tackle the same problems: Cetirizine (Zyrtec®, Aller-Tec®, Wall-Zyr®). Fexofenadine (Allegra®, Aller-ease®, Aller-Fex®, Wal-Fex®).

Claritin^® has been available on the market since 1993 and is one of the most popular antihistamines today. But is it possible for someone to overdose on Claritin^®? The short answer is, yes, it is possible to overdose on Claritin^®.

It is important to take allergy pills and antihistamines as directed. If your allergy medications do not provide enough relief from your symptoms, do not take additional doses. Instead, reach out to your doctor to find a more effective allergy treatment plan.

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.
