Oxymetazoline Hydrochloride

Oxymetazoline Hydrochloride is a topical nasal decongestant (sympathomimetic, alpha-adrenergic agonist) medicine available in Bangladesh under many brand names. Below are its uses, dosage, side effects and precautions — and all brands with their current prices.

Oxymetazoline Hydrochloride is used for the short-term relief of nasal congestion (blocked nose) due to:

• The common cold and flu-like illnesses
• Sinusitis — to ease pressure and help sinus drainage
• Allergic rhinitis and hay fever
• Ear (eustachian tube) congestion associated with colds, when a doctor advises
• Before some nasal examinations or procedures, on a doctor's instruction

It relieves the blockage so you can breathe and sleep more comfortably, but it does not cure the underlying cold, allergy or infection — and it must not be used beyond 3–5 days.

Use Oxymetazoline Hydrochloride exactly as directed on the label or by your doctor. The usual adult dose is 2–3 drops or sprays into each nostril twice daily (morning and night). Blow your nose gently first, keep your head upright while spraying, and sniff lightly.

• Never use it for more than 3–5 days in a row. Longer use causes rebound congestion (rhinitis medicamentosa), in which the nose becomes even more blocked than before
• Do not exceed the stated number of doses in 24 hours
• Children: use only a paediatric strength, and only on a doctor's advice — adult-strength drops or spray must never be given to young children
• Do not share your bottle with others, to avoid spreading infection

When used correctly for a few days, Oxymetazoline Hydrochloride is usually well tolerated. Possible side effects include:

• Temporary burning, stinging or dryness inside the nose
• Sneezing just after use
• Headache
• Rebound congestion — worsening blockage when the medicine is overused or used beyond 3–5 days

Rarely, enough medicine is absorbed to cause body-wide effects: fast or pounding heartbeat, raised blood pressure, nervousness, dizziness or sleeplessness — more likely with overuse, swallowing the solution or use in small children. Stop the medicine and seek medical advice if these occur.

• The 3–5 day limit is the most important rule. Using Oxymetazoline Hydrochloride longer leads to rebound congestion, and many people then become dependent on the spray for months — if your nose is still blocked after 5 days, see a doctor instead of continuing
• Consult a doctor before use if you have high blood pressure, heart disease, thyroid problems, diabetes, glaucoma or an enlarged prostate causing urinary difficulty
• Do not use it together with other decongestant tablets, syrups or sprays without medical advice
• Use only the paediatric strength for children, as advised by a doctor
• Avoid spraying toward the centre wall (septum) of the nose, and do not share the bottle
• Prolonged use can dry and damage the nasal lining

Although Oxymetazoline Hydrochloride acts mainly inside the nose, it can interact with some medicines. Tell your doctor or pharmacist if you take:

• Monoamine oxidase inhibitors (MAOIs) — currently or within the last 14 days: combining them with decongestants can cause a dangerous rise in blood pressure
• Tricyclic antidepressants such as amitriptyline — may exaggerate blood-pressure effects
• Other decongestants — oral pseudoephedrine or phenylephrine in cold-and-flu remedies: additive effects on heart rate and blood pressure
• Blood-pressure medicines — decongestants can work against them

Always mention every medicine, including over-the-counter cold remedies, before using Oxymetazoline Hydrochloride.

Do not use Oxymetazoline Hydrochloride if you:

• Are allergic to oxymetazoline or any other ingredient
• Have angle-closure glaucoma
• Have atrophic (dry) rhinitis
• Are taking, or have taken within 14 days, a monoamine oxidase inhibitor
• Have recently had surgery through the nose or skull base (for example, pituitary surgery)

Adult-strength preparations must not be used in infants and young children — serious side effects, including marked drowsiness, can occur. Children should receive only paediatric formulations prescribed by a doctor.

Pregnancy: Decongestant sprays narrow blood vessels, so they should not be used in pregnancy without medical advice. Occasional, short-term use at the lowest dose may be permitted by some doctors, but safer options — saline nasal washes, steam inhalation — are usually tried first. Always ask your doctor before using Oxymetazoline Hydrochloride while pregnant.

Breastfeeding: Very little oxymetazoline is expected to reach breast milk from nasal use, but data are limited. Use it during breastfeeding only on a doctor's advice, at the lowest effective dose and never beyond 3–5 days.

Store Oxymetazoline Hydrochloride below 30°C in a dry place, away from direct sunlight. Keep the cap tightly closed.

• Do not touch the dropper or spray nozzle to the nose, skin or any surface, and wipe the nozzle clean after use
• Use the bottle for one person only
• After first opening, discard the bottle within the period stated on the label (often about one month)
• Keep out of the reach and sight of children — swallowing this medicine is dangerous for a child
• Do not use after the expiry date
