Over the Counter Cold Treatments
It is never a good time to get sick but unfortunately the cold and flu season is once again squarely upon us. The common cold lasts an average of seven to ten days and usually starts with a sore throat and possibly low grade fever, then progresses to nasal and sinus congestion. Finally, a cough, sometimes productive of mucus, is usually the last symptom to develop and the last to resolve. There is not yet a cure for the common cold and antibiotics not only won’t help but increase the risk of allergic reactions, side effects, and development of resistant bacteria. Plenty of rest and fluids is a mainstay of treatment but there are also many medicines available over-the-counter that can help make things a little more manageable – the key is picking the right medicines for the symptoms you are having.
Over-the-counter cold preparations are confusing with endless combinations of medicines and claims to alleviate certain symptoms. The best approach to selecting the most helpful one is to understand what active ingredients are in each pill and what they are expected to treat. This can help you tailor what you are taking to your current symptoms and limit side effects.
Dextromethorphan, also termed as “DM”, is a cough suppressant that acts directly on the cough center in the brain. It comes as a liquid cough medicine or as a pill. In some studies two teaspoons of honey were shown to be just as effective for reducing nighttime coughing.
Guaifenesin works by thinning mucus or phlegm. This can be helpful if you are having a lot of post-nasal drip (mucus down the back of your throat, clearing your throat a lot), or are coughing up mucus. It should be taken with plenty of water.
Oxymetolazone is a nasal spray also sold under the brand name Afrin. It can give you quick relief from nasal congestion but it cannot be used for more than 72 hours or 3 days in a row. If used longer than that it can actually cause worsening congestion. I like to use Afrin for those nights when you simply cannot breathe out of your nose and the misery of that keeps you from sleeping. It also can be helpful if you are congested before plane trips to help your ears equilibrate to pressure changes.
Pseudoephedrine is a very effective decongestant that is sold behind the pharmacist’s counter though you do not need a prescription for it. You will need to show identification to purchase it and are limited to the quantity you can buy at one time. It is the “D” component in Mucinex –D, Allegra – D, etc. Decongestants relieve nasal stuffiness by narrowing blood vessels and reducing swelling in the nose. This narrowing can affect other blood vessels as well, which can increase blood pressure. This medicine is not a good choice for people with heart disease or poorly controlled high blood pressure. Some people cannot take pseudoephedrine because it makes them feel jittery, spacey, or gives them palpitations. It comes in a 4-6 hour preparation or a 12-hour preparation. Until you know how it affects you I recommend the shorter lasting form.
Pharmacies tend to be sold out of it often during the height of cold season so I like to make sure I always keep some on hand.
Phenylephrine is the decongestant that is sold in the pharmacy shelves and can be a good choice for people who do not like the way pseudoephedrine makes them feel. Some feel it is a less effective decongestant.
Drowsy antihistamines include Benadryl (diphenhydramine) and doxylamine which is found in NyQuil, Alka-Seltzer Night, and other night time preparations.
Many combination pills will also include acetaminophen as a pain reliever and fever reducer. Be mindful of how much you are taking. It is best not to take additional acetaminophen, or Tylenol, with these as too much can be toxic to your liver.
