Allergex: Uses, Dosage, Side Effects, Interactions

Allergex is a South African brand of loratadine, a medicine used to relieve symptoms of allergies, such as runny nose, sneezing, or itchy eyes, nose, or throat. Allergex is also given to help redness and itching caused by hives.

Each Allergex Non-Drowsy tablet contains 10 mgs of Loratadine which is micronized and 75 mg of lactose monohydrate, while 5 ml of Allergex Non-Drowsy syrup on the other hand, only contains 5 mg of micronised Loratadine, as well as 0, 1% m/v sodium benzoate as a preservative, as well as 1,000 mgs of sucrose.

Loratadine is in class of drugs called antihistamines. It works by blocking the effects of a substance called histamine in your body. The U.S. Food and Drug Administration (FDA) approved this medicine in 1993. Both Allergex Non-Drowsy syrup and tablets are indicated for the relief of symptoms associated with allergic rhinitis, rhinorrhoea (runny nose), itching of the nose and throat, chronic idiopathic urticaria (hives) and other allergic dermatoses (allergic skin reactions).

How long does Allergex stay in your system?

The elimination half-life of loratadine is 8–14 hours and that of its metabolite is 17–24 hours, which accounts for the 24-hour duration of action of the drug. Loratadine reaches peak plasma concentration in 1-2 hours; the metabolite does so in 3-4 hours. Allergex stay in your system for about 10 to 20 hours.

How many Allergex tablets can I take?

Use Allergex exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cold or allergy medicine is usually taken only for a short time until your symptoms clear up.

Allergex is usually taken once per day. Follow your doctor’s instructions.

Allergex Non-Drowsy Syrup can be prescribed to both adults and children of two years and over, but the tablets can only be used by adults. The dosage indicated for children and adults also vary.
