Diphenhydramine

Diphenhydramine is a first-generation antihistamine primarily indicated to treat symptoms of allergies and hay fever. It also helps with short-term sleep issues and motion sickness, and may assist with certain movement disorders like Parkinson’s disease. Unlike newer antihistamines, Diphenhydramine can cross the blood-brain barrier, leading to its sedative effects. While effective, it should be used with caution, particularly in elderly individuals, due to an increased risk of cognitive decline and anticholinergic side effects. Caution is also advised when combining it with other central nervous system depressants, such as alcohol or sedatives. You can buy Diphenhydramine online from Canada using a valid doctor’s prescription.

Diphenhydramine functions by blocking histamine receptors, which are natural substances in the body that play an important role in immune responses. This drug targets H1 receptors specifically, preventing histamine from causing symptoms such as sneezing, itching & swelling. Additionally, it blocks acetylcholine receptors, which contributes to its sedative effects and can help with motion sickness. It can also help alleviate symptoms of Parkinson’s disease by reducing involuntary movements.

Common Diphenhydramine side effects may include:

• Dizziness
• Drowsiness
• Upset stomach

Serious side effects (rare):

Note: Call your healthcare provider if you experience any serious symptoms or unusual changes.
