Each year in SA, about five million people
contract influenza and 9 500 people die from causes related to the flu
according to the National Institute of Communicable Diseases (NICD). General
complications from a cold or flu can include bacterial pneumonia and a
worsening of chronic medical conditions such as congestive heart failure,
asthma or diabetes.
Mariska Fouche, spokesperson for Pharma
Dynamics, says when certain colds and flu drugs are taken in combination with
other chronic medications, it could lead to serious complications.
“What is most alarming is that while most
South Africans choose to self-medicate a cold and flu these days, very few are
familiar with the active ingredients in cough, cold or flu pharmaceuticals and
how these interact with their chronic drug regime.”
What to watch for
Fouche lists the following medications to
watch out for because of possible drug interactions.
“Pseudoephedrine and phenylephrine are stimulants and should be avoided if you suffer from diabetes, heart disease, thyroid disease or glaucoma. These products interfere with blood pressure medications and can cause erratic heart palpitations and raise your blood pressure, which can be extremely dangerous when you suffer from these conditions.
“Stimulants are often used in cold and flu
medication because of their nasal decongestive properties but have a major
adverse effect on patients suffering from high blood pressure.
“If you consider that almost three in 10
adults in SA – 6.3 million people – have high blood pressure, they could be
mixing a potentially dangerous cocktail when taking the wrong cold and flu
remedies, so be sure to read the label first of every OTC medication or speak
to a pharmacist before making the purchase,” she advises.
For those with sensitive stomachs, Fouche
suggests opting for an over-the-counter cold and flu drug that doesn’t contain
aspirin.
“Aspirin is known to irritate the stomach
lining. Most cold and flu medications contain a general pain reliever for aches
and pains associated with the condition, so rather choose a remedy which
contains paracetamol instead.
“Diabetics always need to look for alcohol-
and sugar-free cold and flu medications, containing artificial sweeteners such
as aspartame and sorbitol which are generally considered to be safe for
patients with diabetes.”
Aspirin, ibuprofen and naproxen should also
be avoided and diabetics are advised to always monitor their blood glucose
levels more closely when taking cold and flu medication or any OTC medication
for that matter.
“Saline nasal sprays and antihistamines are
also safe options to relieve nasal congestion and for those who prefer herbal
remedies rather steer clear of Echinacea if you are on methotrexate for the
treatment of rheumatoid arthritis or corticosteroids for any reason.
“Efferflu C is a widely used OTC cold and
flu drug and is recommended by doctors and pharmacists as safe in patients
suffering from heart disease, asthma, stomach ulcers and diabetes.
“However if you take medication for any chronic ailment, always check in with your doctor if your cold symptoms last longer than 10 days or if you develop a fever of over 38°C, a sinus headache, earache, thick green nasal discharge or phlegm, or a cough that doesn’t go away after your other cold symptoms subside,” says Fouche.
