Chlorphenoxamine

Chlorphenoxamine is a histamine antagonist, specifically an H1 antagonist, which is marketed in Europe by Boehringer Ingelheim and Sanofi Aventis under various trade names. It is used for the treatment of allergic reactions, and has sedative and analgesic effects.

Pharmacology

Chlorphenoxamine is an antihistamine, which means it works by blocking the action of histamine in the body. Histamine is a substance that the body produces in response to certain allergies or irritations. By blocking the action of histamine, chlorphenoxamine can help to alleviate the symptoms of allergic reactions, such as itching, sneezing, and watery eyes.

In addition to its antihistamine properties, chlorphenoxamine also has sedative and analgesic effects. This means it can help to reduce pain and induce sleep, which can be beneficial for individuals who are suffering from severe allergic reactions or other conditions that cause discomfort and difficulty sleeping.

Uses

Chlorphenoxamine is used for the treatment of various allergic reactions, including hay fever, urticaria (hives), and angioedema (swelling of the skin). It can also be used to alleviate the symptoms of the common cold and other upper respiratory tract infections.

In addition to these uses, chlorphenoxamine can also be used to help manage the symptoms of certain skin conditions, such as dermatitis and eczema. It can also be used to help manage the symptoms of certain eye conditions, such as conjunctivitis.

Side Effects

Like all medications, chlorphenoxamine can cause side effects. Some of the most common side effects include drowsiness, dizziness, and dry mouth. Less common side effects can include nausea, vomiting, and constipation.

In rare cases, chlorphenoxamine can cause serious side effects, such as confusion, hallucinations, and seizures. If you experience any of these side effects, you should seek medical attention immediately.
