Nycof D(14 mg+6.5 mg+2 mg)/5 ml

Nycof D (14 mg+6.5 mg+2 mg)/5 ml is an over-the-counter combination product used for the short-term, symptomatic relief of dry, irritating (non-productive) cough and associated upper respiratory symptoms of the common cold, such as throat irritation and throat discomfort.

• Established use: Temporary relief of cough due to minor throat and bronchial irritation associated with the common cold or inhaled irritants, in patients old enough per product labeling.
• Symptom-soothing adjunct: The levomenthol component provides a cooling, soothing sensation on the throat that can reduce the urge to cough and ease minor throat discomfort.
• Not indicated for: Productive (chesty) cough with thick mucus, chronic cough associated with asthma, chronic bronchitis, emphysema, or smoking, or cough accompanying a serious underlying condition — a physician should be consulted in these situations.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml is intended only for temporary self-treatment of mild, self-limited cold symptoms and is not a cure for the underlying cause of cough.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml combines three active ingredients, each contributing a distinct action to relieve cough and cold symptoms:

• Diphenhydramine (as hydrochloride) — a first-generation sedating antihistamine with additional antitussive (cough-suppressing) and anticholinergic activity.
• Dextromethorphan (as hydrobromide) — a centrally-acting, non-opioid antitussive that suppresses the brain's cough reflex.
• Levomenthol — a cooling, soothing agent that relieves minor throat irritation and gives a sensation of eased breathing.

Exact strengths per dose unit (syrup, lozenge, or other formulation) vary by manufacturer and product presentation; always check the product label/pack insert of the specific Nycof D (14 mg+6.5 mg+2 mg)/5 ml product dispensed for exact per-unit content.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml is a fixed-dose combination over-the-counter (OTC) cough and cold preparation. It pairs a sedating antihistamine and antitussive (diphenhydramine) with a centrally-acting cough suppressant (dextromethorphan) and a soothing, cooling agent (levomenthol) to provide multi-mechanism, short-term relief of dry cough and minor throat irritation that accompany upper respiratory tract infections such as the common cold.

It is available (formulation-dependent) as an oral liquid/syrup or lozenge for self-limited, short-course use, and is not intended to treat the underlying infection or replace medical care for persistent or worsening symptoms.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml belongs to the therapeutic class of OTC Cough and Cold Preparations, combining:

• A first-generation H1-antihistamine / antitussive (diphenhydramine)
• A non-opioid, centrally-acting antitussive (dextromethorphan)
• A topical/oral demulcent and cooling agent (levomenthol)

Nycof D (14 mg+6.5 mg+2 mg)/5 ml works through three complementary mechanisms:

Absorption of diphenhydramine and dextromethorphan occurs after oral administration, with hepatic metabolism (dextromethorphan mainly via CYP2D6) and renal excretion of metabolites; levomenthol acts predominantly locally on oropharyngeal mucosa.

Take Nycof D (14 mg+6.5 mg+2 mg)/5 ml exactly as directed on the product packaging.

• If a liquid/syrup, measure the dose using the marked measuring cup or oral syringe provided — not a household spoon.
• If a lozenge, allow it to dissolve slowly in the mouth; do not chew or swallow whole.
• May be taken with or without food.
• Because diphenhydramine causes drowsiness, an evening/nighttime dose is often preferred; avoid driving or operating machinery after use.
• Do not use for more than the short duration recommended on the label (see Duration of Treatment) without medical advice.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml has the following clinically significant interactions:

• Monoamine oxidase inhibitors (MAOIs): Concurrent use, or use within 14 days of stopping an MAOI, with the dextromethorphan component can precipitate serotonin syndrome (agitation, hyperthermia, autonomic instability) — combination is contraindicated (see Contraindications).
• Other CNS depressants (alcohol, sedatives, hypnotics, opioids, benzodiazepines): Additive sedation and respiratory/CNS depression when combined with the diphenhydramine component — avoid concurrent use.
• Other anticholinergic drugs (e.g., tricyclic antidepressants, other antihistamines): Additive anticholinergic effects (dry mouth, urinary retention, constipation, confusion) with diphenhydramine.
• Selective serotonin reuptake inhibitors (SSRIs) and other serotonergic drugs: Increased risk of serotonin syndrome with dextromethorphan; use with caution.

Reported side effects of Nycof D (14 mg+6.5 mg+2 mg)/5 ml include:

• Common: Drowsiness/sedation, dizziness, dry mouth, thickened bronchial secretions.
• Less common: Blurred vision, constipation, mild nausea/GI upset, mild throat/mouth tingling or cooling sensation from levomenthol.
• Uncommon but important: Urinary retention/difficulty urinating, palpitations, confusion or paradoxical excitation (more common in children and the elderly), impaired coordination.
• Rare/with misuse or overdose: Hallucinations, dissociative or euphoric effects (dextromethorphan misuse at high doses), serious anticholinergic toxicity.

Seek medical attention if severe drowsiness, difficulty breathing, irregular heartbeat, or signs of an allergic reaction occur.

Data on the combined use of Nycof D (14 mg+6.5 mg+2 mg)/5 ml in pregnancy and lactation are limited. As a precaution, this product should be used in pregnancy only if clearly needed and if the potential benefit justifies the potential risk to the fetus; a physician should be consulted before use, particularly in the first trimester.

Diphenhydramine and dextromethorphan are excreted in breast milk in small amounts; diphenhydramine may reduce milk supply and cause sedation/irritability in the nursing infant. Use during breastfeeding only under medical advice, favoring the lowest effective dose for the shortest necessary duration.

• Nycof D (14 mg+6.5 mg+2 mg)/5 ml may cause marked drowsiness; avoid driving, operating machinery, or consuming alcohol while using this product.
• Do not exceed the labeled dose or duration of use — for self-treatment, limit use to the short course indicated (see Duration of Treatment); persistent, recurrent, or worsening cough, cough with fever/rash/persistent headache, or cough lasting beyond the labeled duration warrants medical evaluation.
• The dextromethorphan component carries a risk of misuse/abuse at supratherapeutic doses due to dissociative effects — keep out of reach of adolescents and store securely.
• Use with caution in patients with narrow-angle glaucoma, urinary retention/prostatic enlargement, asthma or chronic obstructive pulmonary disease (impaired ability to clear thickened secretions), and in the elderly, who are more sensitive to anticholinergic and sedative effects (see Use in Special Populations).
• Use with caution in hepatic impairment (reduced dextromethorphan metabolism) and in poor CYP2D6 metabolizers.
• Not a substitute for medical evaluation of cough associated with excessive phlegm, chronic lung disease, or smoking.

Overdose of Nycof D (14 mg+6.5 mg+2 mg)/5 ml is a medical emergency. Features may include marked sedation or paradoxical CNS excitation/agitation, severe anticholinergic toxicity (dilated pupils, flushing, high fever, tachycardia, urinary retention, hallucinations), and, with large amounts of dextromethorphan, dissociative effects, seizures, or serotonin-syndrome-like features.

If overdose is suspected, seek immediate medical attention or contact a poison control center/emergency services right away. Do not attempt to treat an overdose at home.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml is intended for short-term, self-limited symptomatic use only — typically no more than 5–7 days. If cough or cold symptoms persist beyond this period, worsen, or are accompanied by high fever, rash, or persistent headache, discontinue use and consult a physician.

Antihistamine (first-generation H1-receptor antagonist) + Antitussive (non-opioid, centrally-acting cough suppressant) + Oral/topical demulcent and cooling agent — combined as an OTC cough and cold preparation.

Nycof D (14 mg+6.5 mg+2 mg)/5 ml relieves cough and throat irritation through combined central and local action: diphenhydramine's H1-blockade and CNS depression reduce cough reflex sensitivity and dry secretions; dextromethorphan raises the cough threshold at the brainstem cough center; and levomenthol produces a local cooling/soothing sensation on the throat mucosa that eases irritation and the urge to cough.

Use of Nycof D (14 mg+6.5 mg+2 mg)/5 ml in children requires caution:

• Not recommended in children below the minimum age stated on the specific product label (commonly under 4–6 years), consistent with regulatory advisories on OTC cough-and-cold combination products in young children, in whom serious adverse events (including fatalities) have been reported with such combinations.
• In older children (per product label, generally ≥6 or ≥12 years depending on formulation), use only a pediatric-appropriate strength and dose as directed on the label or by a physician.
• Safety and efficacy of this specific fixed-dose combination have not been formally established across all pediatric age groups; a physician or pharmacist should be consulted before use in any child.
