About ephedrine nasal drops
Tipo de medicamento | A nose (nasal) decongestant |
Usado para | A blocked nose (nasal congestion) |
Disponible como | Nose drops |
A common symptom of a cold is a blocked (congested) nose. A stuffy, blocked-up feeling in your nose can also occur in the absence of a cold. This is because the inside lining of your nose is sensitive to changes in the atmosphere (such as temperature and humidity changes) and this also can lead to symptoms of nasal congestion.
You may find a hot steamy shower or a steam inhalation will help to clear a blocked nose but, where this does not provide sufficient relief, a decongestant such as ephedrine may be useful. Ephedrine causes the small blood vessels in your nose to become narrower. This reduces the thickness of the lining of your nose which is causing the congestion, and relieves the blocked-up feeling.
Ephedrine nose drops (also called nasal drops) are available on a prescription from a doctor or dentist. You may also be able to buy a small pack of nose drops from a pharmacy, without a prescription. Ephedrine drops are suitable for adults and for children aged 12 years or over. They are not suitable for children under 12 years of age.
Before using ephedrine nasal drops
Volver al contenidoSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using ephedrine nasal drops it is important that your doctor, dentist, or pharmacist knows:
Si estás embarazada o amamantando.
If you have diabetes, high blood pressure, or heart disease.
If you have an overactive thyroid gland, or any problems with your prostate gland or kidneys.
Si alguna vez has tenido una reacción alérgica a un medicamento.
If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines. You must reportado use ephedrine if you have taken a medicine for depression, known as a monoamine-oxidase inhibitor (MAOI) within the previous two weeks.

How to use ephedrine nasal drops
Volver al contenidoSopla tu nariz suavemente para despejarla.
Unscrew the dropper from the bottle. Make sure the tip of the dropper is under the surface of the liquid in the bottle, and then squeeze the bulb of the dropper to part fill the dropper with the liquid.
Tilt your head back a little and bring the part-filled dropper close to one of your nostrils. (Do not put the dropper into your nostril.)
Gently squeeze the bulb of the dropper to release one or two drops of the liquid into your nostril. Repeat the process to release one or two drops into the other nostril also. Try not to touch your nose with the dropper as you do this.
Keep your head tilted back for a few moments to allow the drops to spread around the inside of your nose.
Close the bottle by screwing the dropper back on to the bottle gently.
Obteniendo el máximo de tu tratamiento
Volver al contenidoBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. This will give you a step-by-step guide of how to use the drops, and will also provide you with a full list of the side-effects which you may experience from using them.
The usual dose is one or two drops into each nostril, three or four times a day when needed. Do not use the drops more than four times a day.
Ephedrine nasal drops should be used for short periods of time only. Do not use them for more than seven days. This is because the downside of using the drops is that nasal congestion can often return (recur) when you stop using them. This is called rebound congestion, and it can lead to cycles of further problems with congestion. Using the drops for only a few days when necessary will help to prevent this from becoming a problem.
Bottles of nose drops should only be used by one person. This is to avoid spreading infection from one person to another. Do not 'share' the bottle with other people.
Nasal congestion can be eased by inhaling warm moist air. Many people find that having a hot shower is often the best way to relieve their symptoms.
