Alavert is an antihistamine medication available over-the-counter. Compared with other non-prescription antihistamines, this drug is less likely to cause drowsiness. Because it works by blocking a specific type of histamine receptor in the body, Alavert can help relieve and prevent allergy symptoms. The medication comes in the form of tablets or orally disintegrating tablets. Possible side effects include headaches, fatigue, and dry mouth.
What Is Alavert?Alavert® (loratadine) is an antihistamine medication available without a prescription. It is also available in combination with a decongestant (see Alavert-D for more information). Compared to many non-prescription antihistamines, Alavert is much less likely to cause drowsiness.
How Does It Work?Alavert is part of a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body known as H1 receptors.
