Cough medications are commonly purchased to treat coughs that occur when you have an upper respiratory tract infection (URTI). Cough is often divided into a dry cough, and the cough chesty. However, it is believed that cough medicines do not work. However, some people feel that work for them and they are believed to be quite safe drugs. Children age six and under should only be administered simple cough mixtures such as glycerin, honey and lemon.
Coughing is an automatic (reflex) response to irritation of the airways in the lungs. The airways of the lungs can get irritated by a number of things – for example, too secretions (liquid), infections, allergens and irritant gases, or dust or smoke.
Having a cough is the main symptom of an upper respiratory tract infection (URTI). However, a cough can be a symptom of other diseases such as asthma or lung disease.
This brochure is only cough when used to treat coughs caused by URTI. It is assumed that you are sure that you know that I have nothing more serious or other cause of cough. Consult your doctor if you are unsure.
When you have a cough caused by a URTI, usually described as being a chesty cough or a dry cough. If you have a chesty cough this usually means your lungs are producing more mucus (fluid) than normal, because you have an infection, and a cough with this excess mucus. If you have a dry cough that usually means that you are coughing a lot, but there is mucus when you cough.
Infections of the throat (larynx), or the main airway (trachea), or airway to the lungs (bronchi) are common. These infections are sometimes called laryngitis, tracheitis, bronchitis or. Doctors often refer only to upper respiratory tract infection (URTI) to include any or all of these infections. IVRS Most are due to a viral infection. Cold symptoms can also occur if the infection affects the nose.
Symptoms usually peak after 2-3 days, and then gradually clear. However, the cough may persist after the infection is gone. This is due to inflammation in the airways, caused by infection, it may take a while to settle. It may take 2-3 weeks after other symptoms have disappeared, cough to clear completely.
Cough medicines are a group of drugs that aim to either suppress a dry cough, or are intended to help you cough up mucus (chesty cough) when you have a URTI. Cough medications that are intended to help eliminate dry cough are sometimes called antitussives. Cough medications that are intended to help you cough up mucus are sometimes called expectorants.
A lot of cough medicines are available to buy at pharmacies or supermarkets. They usually contain one or more of the following:
A glycerin, honey and lemon cough syrup is also available for purchase. This preparation has no active ingredient as such. Is believed to have a calming action.
Cough medications may also contain other drugs such as acetaminophen or ibuprofen. Some contain alcohol.
Cough medicines are believed to act in different ways, depending on what is the active ingredient:
There is good evidence from research studies that cough medicines work. Is believed to have little benefit in cough (or cold) symptoms. However, some people feel that work for them and these drugs are considered safe for the vast majority of adults and children over six years old.
If you have a dry cough, a preparation containing an antitussive dextromethorphan or pholcodine is best to try. If you have a chesty cough, a preparation containing an expectorant such as guaifenesin or ipecac is best to try. Your pharmacist can advise what may be right for you. If you are buying these drugs at the supermarket, which are usually clearly labeled on the box state what kind of cough that claim to help.
Some important considerations about cough medicines are:
For children under six years of age, just give them simple preparations such as glycerin, honey and lemon. Do not give to children who are under cough six years with any of the aforementioned active ingredients (antitussives, expectorants, antihistamines and decongestants). This is because the risk of a young child that has a side effect of these preparations is one greater than the benefit of the medicine.
Always check with your pharmacist before buying any medication at the pharmacy or supermarket to see if they are safe to take with any other medicines you are taking.
Some cough medicines contain other drugs as well. For example, some may contain paracetamol, ibuprofen, and some contain alcohol. This is important if you are already taking paracetamol or ibuprofen to relieve symptoms of infection (eg, high temperature). This is because you can take too much acetaminophen or ibuprofen (overdose), but not be aware of it. Taking too much acetaminophen can cause liver damage.
If you are taking aa particular type of antidepressant – monoamine oxidase (MAO) – these may react with certain ingredients in cough medicines. Taking this together can cause a huge spike in blood pressure (hypertensive crisis), or make you very excitable or depressed. In particular, people taking MAOIs should avoid dextromethorphan, ephedrine or pseudoephedrine while taking an MAOI antidepressant and for two weeks after it stopped.
Dextromethorphan when taken with an MAOI antidepressant may make you very excitable or depressed. Ephedrine, pseudoephedrine and phenylpropanolamine, when taken at the same time as an MAOI antidepressant, can cause large increases in blood pressure (hypertensive crisis).
Most people taking cough medicines have no side effects. Some cough medicines (eg pholcodine and diphenhydramine) can cause drowsiness. If you feel drowsy after taking a cough medicine, you should not drive or operate machinery. The booklet that comes with your medicine indicate whether the drug can cause drowsiness.
Pholcodine can cause constipation.

As with all medicines, cough medicines should only be taken for the shortest period of time, and most people only need to use a cough medicine for a few days. In general, most coughs do not last more than 2-3 weeks. If the cough lasts longer than this, then you should see your doctor.
Most people can take a cough medicine. The exception is children under six. These children should only be given cough medicines with no active ingredients – for example, glycerin, honey and lemon. If you are taking other medications or if you are not sure whether to take a cough medicine, ask your pharmacist.
