Cold and cough combination medicines are usually used to provide relief for people suffering from the cough that often accompanies common ailments, including hay fever, influenza, and colds. These medicines are not effective in the treatment of the more chronic form of cough that often results from smoking, as a symptom of emphysema or asthma, or where the cough produces large quantities of phlegm or mucus.
Cold and cough combination medicines usually contain multiple active ingredients. For instance, some products are made up of a decongestant, an analgesic, and an antihistamine, as well as a drug to tackle the cough. When self-medicating, you must choose a medicine that best matches your symptoms. You should also look for a brand that contains those drugs that will best treat your symptoms. For the avoidance of doubt, ask your pharmacist for guidance.
Each different medicine will be made up of components that can cause different side effects and varied contraindications. You must, therefore, check the packaging to see what ingredients the product contains, before you start using it. There are a variety of components often found in cold and cough combination medicines:
Antihistamines prevent or relieve the symptoms that typically accompany allergies and hay fever. They may also be effective in tackling common cold symptoms, including sneezing and a runny nose. Antihistamines work by inhibiting the production of a naturally produced chemical known as histamine. Antihistamines that are used in these medicines typically include:
Decongestants are designed to cause the blood vessels in the nasal passages to become narrowed, effectively clearly congestion. This can also exacerbate hypertension in people who suffer from this malady. Decongestants that are commonly included in cold and cough combination medicines include:
Antitussives are used in cold and cough combination medicines to help relieve the symptoms of coughing. Antitussive drugs work on the area of the brain that triggers the cough response, dulling the response and thus preventing the feeling of the need to cough. Some antitussives contain narcotics, and there is a danger of addiction if the drugs are taken to excess or for long periods. Stopping the treatment abruptly may cause physical withdrawal symptoms.
Antitussives that contain narcotics include:
Expectorants have the effect of loosening any phlegm or mucus that has collected in your chest. Guaifenesin is the used in cold and cough combination medicines as an expectorant. Other expectorant ingredients include:

Some of the components of cold and cough combinations can pass through into breast milk and thus into a nursing infant. Acetaminophen, caffeine, and alcohol do pass into breast milk, but do not usually cause problems for nursing babies as the amounts are relatively small.
Antihistamine does pass into breast milk, and even small amounts can cause side effects, including irritability and overexcitement in the nursing infant. This drug can also mean a greatly reduced flow of milk in some people, so the baby may not receive the nutrition it needs, resulting in poor growth rates.
The narcotic substances that are contained in some cold and cough preparations generally include codeine. Codeine is synthesized by the body to form morphine, at different rates in different people. If a woman who is breastfeeding metabolizes morphine particularly quickly, there is a risk that a nursing infant could ingest an overdose of morphine. This will cause serious side effects in the child, potentially killing it. If you are breastfeeding, discuss the safe use of cold and cough combination medicines before you begin using them. It may be safer for your baby not to use this kind of medication, unless you are prepared to use an alternative feeding method while you are taking the medicine.

In children who suffer from cystic fibrosis, the side effects that can be caused by iodinated glycerol are much more likely to occur.
Some decongestant medicines may present a greater danger of blood vessel or heart disease to diabetes mellitus sufferers.
Medicines that contain salicylate or aspirin can cause a serious allergic reaction in people who have chronic lung diseases, asthma, or emphysema. This reaction makes breathing more problematic.
Some cough and cold combination medicines that contain antihistamines or anticholinergics can exacerbate problems such as enlarged prostate, difficult urination, and urinary tract blockage.

Patients who suffer from kidney problems should use this medication with caution, because these conditions can cause a build-up of medicine in the body, raising the chance of side effects.

When you are better and you no longer need the medicine, do not keep it. If you discover that your medicine is out of date, you should return it to the pharmacy and ask for a replacement.
It is important to dispose of any unused or out of date medication responsibly. Do not tip syrup down the sink or flush it away down the toilet. Wrap unused medicines in a sealed bag and place them in your trash where they cannot easily be got at by children or animals.
