Loratadine is the generic name of an existing approved brand-name drug called Claritin. It is a second-generation histamine H1 receptor antagonist that works by blocking the action of histamine receptors in the human body, preventing the immune system’s reactions which cause allergy symptoms.
This drug was originally manufactured by Bayer Healthcare, a German company, and first approved by the US Food and Drug Administration in 1993.
This antihistamine is typically used to treat a runny nose, sneezing, watery eyes, skin rash, hives, itching, and other allergy or cold symptoms.
Allergy involves an exaggerated response of the immune system, usually to common substances, like – pollen or foods. If an individual is allergic to a substance, like – pollen, his immune system reacts to the substance as if it was harmful and foreign, and tries to destroy it.
Individuals who have allergies are usually allergic to one or more of the following:
- pet dander;
- certain plants;
- certain medications, like – aspirin or penicillin;
- certain foods, like – shellfish or nuts;
- insect bites;
- bee stings.
Note – perennial allergies can occur throughout the year, while seasonal allergies (like hay fever) happen at specific times of the year.
Syrup – the usual recommended dose for children 2 to under 6 years of age is 1 tsp per day. The maximum recommended dose is 1 teaspoonful in 24 hours. The usual recommended dose for adults and children 6 years and over is 2 tsp per day. The maximum recommended dose is 2 teaspoonfuls in 24 hours.
Capsules – the usual recommended dose for adults and children 12 years of age and older is 10 mg once per day with water.
Tablets – the usual recommended dose for adults and children 12 years of age and older is 10 mg once per day.
Notes – this medicine is typically given once per day in the morning, however, it can depend whether the antihistamine has any sedating effect on the patient and the timing of the symptoms.
Because serious adverse effects (even death) can occur from the misuse of this drug in very young children, do not give this antihistamine to a child younger than 2 years old.
Contact your healthcare professional immediately if an overdose is suspected. Symptoms of overdose may include:
- increased heart rate;

High & Abuse
Since this antihistamine medicine is available as over-the-counter and has no recreational value, it is not presumed that adolescents or young adults could use it to get high.
However, you might be interested that Benadryl (an antihistamine which reduces the effects of natural chemical histamine in the human body) does have some potential recreational effect as a deliriant at doses of 500 mg.
It is not a good idea to mix alcohol with loratadine since alcohol will worsen the sedative side effects of this medicine, usually to an unpredictable degree. In general, combining alcohol and medications also may increase the side effects, like:
- liver damage;
- heart problems;
- impaired breathing;
- internal bleeding;
- loss of coordination;
- abnormal behavior;
- changes in blood pressure.
Important note – drinking alcoholic beverages while taking antihistamines can lead to serious injuries, particularly among seniors. Also, ask your healthcare professional if you have any questions about how alcohol might interact with any medication you are using.
