Antibiotics generally have no effect on symptoms of colds, flu

There are consequences for prescribing antibiotics when they aren’t needed, write Guylene Theriault and Wendy Levinson.

Cold and flu season for many Canadians means getting ready to have their lives and routines thrown off by painful and annoying symptoms. This can mean days off work or school dealing with sore throats, nasal congestion and fever. For parents, it can be challenging to try to comfort young kids with fever, coughing or ear pain.

As doctors, we know that doctors and patients would love a quick fix — a magic bullet to deal with these symptoms. Patients want to get their lives back to normal as quickly as possible.

Unfortunately, antibiotics are not usually the answer. Antibiotics are commonly misused because people believe they will treat the symptoms of colds and flus. In fact, fever, cough and ear pain are usually due to viruses that are not affected by antibiotics. More than half of all antibiotic prescriptions in Canada are estimated to be unnecessary and ineffective.

Common conditions that are usually viral in nature but that are often prescribed antibiotics unnecessarily include sinus infections, ear infections and chest colds (or bronchitis).

Antibiotics do not typically help for any of these conditions and the symptoms will get better with simple rest and time.

It’s hard for us as physicians not to be able to offer a cure and hard sometimes for our patients to accept that there isn’t much to be done aside from managing their symptoms and waiting it out.

A good first step is for doctors and patients to have a conversation about the downsides of unnecessary antibiotics. What harm can taking unnecessary antibiotics do? Plenty.

When trying to treat symptoms that are caused by viral infections, antibiotics don’t help and can actually make patients feel worse.

Antibiotics work by stopping illness-causing bacteria from growing and multiplying.

When diseases are viral in origin, not bacterial, antibiotics have no impact.

Using an antibiotic when not needed also promotes the growth of bacteria that are resistant to commonly used antibiotics.

This makes patients, especially the elderly, more vulnerable to antibiotic-resistant infections and undermines the good antibiotics can do for us and others when they are truly needed.

There are also side-effects to taking antibiotics.

About one in four people who take antibiotics experiences stomach upset, dizziness or skin rashes.

There’s a new tool that you may notice in your doctor’s office to help have conversations about when antibiotics aren’t necessary — it’s called a “viral prescription pad.”

This is a tear off sheet similar to what you might receive for a prescription, except it contains information about symptom-relieving strategies for fevers, aches and pains. It also explains the risks of unnecessary antibiotics and offers examples of when you should go back to see the doctor should symptoms worsen.

Receiving no antibiotics for a cold or flu does not mean no treatment. It just means a different approach.

One way to start the conversation about whether or not an antibiotic is really necessary is to use these three questions developed by Choosing Wisely Canada when talking with your doctor: Do I really need antibiotics? What are the risks?

Are there simpler, safer options?
