Torex Syrup

What It Is & Composition

Torex Cough Syrup is a prescription-only combination liquid (commonly available as 60–100 ml) produced by Torque Pharmaceuticals in India. Each 5 ml dose comprises:

• Diphenhydramine hydrochloride 12.5 mg – a first-generation antihistamine that blocks histamine to calm cough reflex, allergic burning, sneezing and post-nasal drip

• Ammonium chloride 125 mg – expectorant that increases airway secretions to loosen and liquify phlegm

• Terpin hydrate 7.5 mg – expectorant that thins mucus and promotes its mobility

• Sodium citrate 55 mg – a mucolytic that alkalinizes and breaks down dense mucus for easier expectoration

• Menthol (present in specific variants) – adds cooling relief and eases throat sensation

Mechanism of Action

• Thins and liquefy mucus (Ammonium chloride, Terpin hydrate)

• Breaks mucoprotein bonds (Sodium citrate)

• Suppresses cough reflex and soothe airway irritation (Diphenhydramine, Menthol)

Together, these actions help you cough out phlegm more easily, breathe more freely, and reduce throat discomfort.

Indications & Uses

Torex is best when mucus is thick or cough is triggered by seasonal allergies. Seek medical guidance if cough is protracted.

Key Benefits & Advantages

• Offers fast symptom relief, often starting within 30–60 minutes (though formal onset isn’t quantified in trials)

• Addresses multiple cough triggers: mucus, histamine, irritation, sneezing

• Easy-to-administer syrup format: ideal for those who dislike swallowing pills

• Non-addictive, intended for short-term use—generally up to 7 days unless guided by a physician

Dosage & How to Use

*Maximum daily intake is 20 mg diphenhydramine and 500 mg ammonium chloride (i.e., no more than 4 doses or 20 ml per day). Follow printed bottle instructions or physician advice.

Usage Tips: Shake bottle before measuring. Use a calibrated spoon or cup for accuracy. May be taken with or after food—dinner may help reduce nausea in sensitive individuals.

Side Effects

• Common (mild, usually self-limiting): drowsiness, dizziness, dry mouth, blurred vision, nausea, constipation, occasional headache

• Occasional: thickened secretions in lungs, light sedation, coordination impairment

• Rare but serious: allergic rash, tremors, confusion, urinary retention in sensitive individuals

These side effects reflect the antihistamine and expectorant actions. They typically resolve once medication stops. 1mg

Precautions & Contraindications

• Narrow-angle glaucoma, benign prostatic hyperplasia, urinary retention (diphenhydramine’s anticholinergic effects)

• Hypertension, arrhythmia, hyperthyroidism—may intensify side effects

• Recent use of Monoamine Oxidase Inhibitors (e.g. Selegiline, Phenelzine)—risk of serotonin syndrome

• Conditions requiring caution: liver or kidney impairment, elderly population
