What is SDA LABORATORIES Diphenhydramine?

This product is a fast-acting antihistamine containing 50 mg of diphenhydramine per capsule. Diphenhydramine is an active ingredient widely used for the temporary relief of symptoms associated with seasonal and perennial allergies. Each bottle contains 1000 capsules, providing a prolonged supply for continuous control of allergic discomfort.

Benefits for allergies

Diphenhydramine works by blocking the action of histamine, a substance the body releases during an allergic reaction. This helps reduce symptoms such as sneezing, runny nose, itchy throat, and watery eyes. Its fast-acting formula allows for relief to be felt shortly after ingestion, making it especially useful during acute flare-ups or exposure to allergens like pollen, dust mites, or pet dander.

Furthermore, this medication is suitable for both indoor and outdoor allergies, offering year-round versatility. Many users appreciate the convenience of having a large supply that avoids frequent purchases.

Active ingredient and its function

The sole active ingredient is diphenhydramine hydrochloride in 50 mg doses. Diphenhydramine belongs to the group of first-generation antihistamines. Its mechanism involves antagonizing histamine H1 receptors, which decreases the intensity of allergic symptoms. Unlike more modern antihistamines, this one can cause drowsiness, so caution is recommended when driving or operating machinery.

How to take this antihistamine

For adults and children over 12 years of age, the recommended dose is one capsule (50 mg) every 4 to 6 hours as needed. Do not exceed 6 capsules (300 mg) in 24 hours. It is important to follow the package directions and not exceed the recommended dose. This medication can be taken with or without food. If symptoms persist, consult your doctor.

Possible side effects and precautions

The most common side effect is drowsiness. Dry mouth, dizziness, or blurred vision may also occur. It should not be combined with alcohol or other central nervous system depressants. It is contraindicated in children under 6 years of age and in people with narrow-angle glaucoma, prostatic hypertrophy, or asthma. During pregnancy or breastfeeding, consult your healthcare professional before use. Keep out of reach of children.
