OTC ( Over The Counter ) Decongestants ( Sympathomimetics) _____________________________________________________ -Sympathomimetics (as : pseudoephedrine) can be effective in reducing nasal congestion. -Nasal decongestants work by constricting the dilated blood vessels in the nasal mucosa. - The nasal membranes are effectively shrunk, so drainage of mucus and circulation of air are improved and the feeling of nasal stuffiness is relieved. - These medicines can be given orally or applied topically. - Tablets and syrups are available, as are nasal sprays and drops. - If nasal sprays/drops are to be recommended, the pharmacist should advise the patient not to use the product for longer than 7 days. - Rebound congestion (rhinitis medicamentosa) can occur with topically applied but not oral sympathomimetics. - The decongestant effects of topical products containing oxymetazoline or xylometazoline are longer lasting (up to 6 h) than those of some other preparations such as ephedrine. - The pharmacist can give useful advice about the correct way to administer nasal drops and sprays.
