During an allergic reaction, your immune system releases a chemical called histamine, which is responsible for the symptoms of an allergy. Antihistamines work by opposing the actions of histamine by stopping histamine from binding to its target sites in the body.

The chemical structure of drowsy antihistamines means they can enter the brain through what is known as the blood-brain barrier. This makes them more likely to cause drowsiness compared to other antihistamines. Another antihistamine may be a better choice if you need to stay alert, such as for driving or performing skilled tasks.

This medication should not be used by children under 2 years old unless under instruction by your doctor. Like all medications, don’t take them if you have previously had an allergic reaction to the medication, if you have severe kidney or liver problems, or if you have other medications or medical conditions that you would normally discuss with your doctor or pharmacist before starting something new. Do not take it if you have breathing problems, glaucoma, or an enlarged prostate.

Some people are bound to get unwanted side effects as with any medication. Common symptoms include drowsiness, dry mouth, headaches, dizziness, blurred vision, and lack of concentration.
