...your health and medication related questions addressed by a Pharmacist
Dear RX Rated:
I’ve wondered whether or not the cold drugs bought at the pharmacy actually cure a cold. A friend of mine and I were going back and forth about this the last time I became sick. I’m not one to take medications unless I absolutely have to. What do you think?

That is a great question. I’m sure you’ve heard friends telling you, “you better get on top of that cold before it gets bad” as they ramble to find the Pseudofed in the medicine cabinet. Or you have seen your mother, girlfriend, or boyfriend taking the quickest route to the pharmacy to grab a box of Theraflu. Something about sipping that hot cup of steaming medicinal goodness just makes you feel like surely this will get rid of your cold. Don’t let it be lemon or honey flavored. You can almost feel their love steaming straight out of the cup, along with a quick route to recovery.
These common cold products are great for making you feel more comfortable, or maybe even help you make it through another work day (when you really should be keeping your cooties at home). But will the traditional cold medications help you to recover from a cold any more quickly? They generally contain different amounts or variations of common ingredients to address your specific symptoms.
OK, here we go. Class, are you ready???? Without bogging you down in overly detailed explanations, I’ll do my best to break down how most of these ingredients work.
For example, pseudoephedrine (kept behind your pharmacy counter) and phenylephrine are decongestants, which will help the symptoms of a stopped up nose by constricting the vessels within the mucous membranes of the nasal passages.
Dextromethorphan is a cough suppressant contained in your cough medications or any over the counter medication claiming to help with cough. It works partly by suppressing the cough center in the brain.
Any number of antihistamines, i.e. brompheniramine, chlorpheneramine, etc. will help with a runny nose by blocking the body’s histamine response, which can cause runny nose, sneezing, and watery eyes.
Acetaminophen (which many of us know as Tylenol) will help with fever, aches, pains, and even a sore throat. It works by blocking pain impulses, as well as inhibition of the body’s temperature regulation center.
There is also guaifenesin, which is an expectorant. It works to decrease the viscosity of the mucus in the chest, in order to loosen it up and decrease chest congestion.
If you turn over the boxes of the majority of cold medications, these are most of the active ingredients that you will find. Do they make you feel better? Absolutely! To answer your question, do they help you to recover from your cold faster? Absolutely not. The common cold is caused by any of around 200 viruses. Clearly, none of these ingredients contain any type of antiviral properties. Usually, a cold will run its course and resolve in about 1 week.
Now, there are some alternative remedies that have been shown in some studies to shorten the duration of your misery, i.e. vitamin c and zinc. But I think I’ve answered your question. As a side note, some of these ingredients are not recommended if you have certain health conditions, such as high blood pressure or diabetes, or are on certain medications. Make sure to read the product packaging to check for warnings, and consult with your doctor or pharmacist before taking if you have concerns. Thanks Melinda!
What works for you? Are there any store bought medications that you swear by? Does your family practice home remedies that predate the women's suffrage movement?
Let’s hear about it.
Well, that wraps up the first edition of RX-Rated with a PharmD. I hope it was informative. Please keep your questions coming. Send them to rx-rated@live.com.
I’ll see in two weeks.
