According to the Centers for Disease Control and Prevention (CDC), approximately eight to ten percent of the United States population will become sick with an influenza (flu) virus yearly. The average American will also catch between two to three colds per year. A cold and the flu are both caused by viral infections and produce various unpleasant symptoms. Colds are often accompanied by nasal congestion and/or a runny nose, sneezing, coughing, and a sore throat. Flu viruses can cause similar symptoms: fatigue, fever, head and body aches, and, for some, diarrhea and vomiting. While there is no cure for either illness, several over-the-counter medications and home remedies may offer symptom relief.
There are more over-the-counter (OTC) options than ever before, and it can be difficult to decide which is best for you. Certain health conditions may also impact your decision.
Talk with a provider before taking OTC cold and flu medicines if you:
- Have a chronic medical condition
- Take prescription medications
- Are pregnant or breastfeeding
- Are choosing medicine for a young child
Our primary care team shares tips on selecting the best OTC medication(s) to manage your symptoms and which to avoid, if necessary.
Antibiotics
When cold and flu symptoms strike, it can be tempting to ask your primary care physician to prescribe an antibiotic. Not only will antibiotics not alleviate your symptoms, but antibiotics are also effective in killing bacteria, not the viruses responsible for cold and flu bugs. When overused, your body begins to build up tolerance to them. This causes antibiotics to be less effective when you actually need them.
Antihistamines
When cold symptoms include a runny nose, sneezing, or watery eyes, antihistamines can provide relief by blocking histamine, a chemical your body releases in response to irritants. Common OTC antihistamines include diphenhydramine (Benadryl) and loratadine (Claritin). Older antihistamines like diphenhydramine can cause drowsiness, making them suitable for nighttime use, while newer options like loratadine or cetirizine (Zyrtec) are non-drowsy alternatives. If you have glaucoma, an enlarged prostate, or urinary retention issues, consult your physician before taking antihistamines, as they can worsen these conditions. Keep in mind that while antihistamines effectively manage symptoms, they may also thicken mucus, potentially making congestion worse for some people.
Cough suppressants
A cough is a common, often frustrating cold symptom, especially if it is preventing you from getting a good night’s sleep. If you develop a cough that lasts for several days or are having difficulty sleeping through the night, a cough suppressant can help. For the most relief, select one that contains the active ingredient dextromethorphan (often listed as DM). Keep in mind that while it may be uncomfortable, coughing is an important part of your body’s healing process. Coughing helps to clear mucus and other irritants from your lungs. Suppressants may prevent this clearing from happening, keeping you sick longer, so try to use them sparingly.
Cough syrups and throat drops
Many people rely on cough syrups or throat drops to soothe their throat. While they can provide temporary relief, many contain relatively high amounts of sugar. If you are diabetic, be sure to select a sugar-free option to avoid raising your blood sugar level.
Decongestants
Decongestants are often used to relieve a stuffy nose and reduce inflammation within your nasal cavity. There are several types available, although not all decongestants are as effective. For the most relief, select those that contain pseudoephedrine and are available behind the pharmacy counter. When used appropriately, pseudoephedrine is considered safe and effective, but you will be required to show an ID to purchase it.
Conditions That May Require Extra Caution
High blood pressure, heart disease, or diabetes: Oral decongestants can raise blood pressure and blood sugar. If you have any of these conditions, your primary care provider or specialist may recommend a spray-based decongestant or saline solution instead, which can relieve symptoms without entering the bloodstream.
Enlarged prostate (benign prostatic hyperplasia, BPH): Decongestants can tighten the muscles in the prostate and bladder, which may worsen urinary symptoms. Depending on your symptoms, it may be best to avoid oral decongestants and use a saline spray instead.
If you’re unsure which option is right for you, your primary care provider can help guide that decision based on your symptoms and health history.
Echinacea
Echinacea is a popular herbal supplement thought to help boost your immune system and prevent illness and infections. While its exact effectiveness is still unclear, some research has found that it may slightly decrease your odds of catching a cold. It should not be taken long-term (no more than 10 consecutive days) and is most effective if taken when your symptoms first appear.
If you suffer from seasonal allergies, especially if you are sensitive to ragweed, you should avoid Echinacea. It is a plant-based supplement that is closely related to the ragweed family. This increases your risk of developing a variety of side effects, including stomach upset and skin rashes.
Expectorants
Often, during a cold, the mucus in your nasal cavity will begin to drain, causing you to cough and irritate your throat. Expectorants, such as Mucinex, are often used to thin mucus, making it easier to cough up and keep airways clear. While expectorants are an effective way to relieve symptoms, you can often achieve similar results without medication. Try increasing your water intake, taking a hot shower or using a humidifier instead.
Pain relievers
When you experience head and body aches or a fever, pain relievers, including acetaminophen or ibuprofen, are often the first thing you reach for. If you are prescribed blood thinners and have heart disease or digestive issues, including ulcers, you should avoid anti-inflammatory medications (ibuprofen and naproxen). Anti-inflammatory medications can cause your body to retain fluid and affect your kidney function, which causes your blood pressure to rise. Instead, stick to acetaminophen products, like Tylenol, for pain relief.
Ginseng
Ginseng is a popular natural remedy for cold prevention and treatment. Research has shown it can be effective in supporting a healthy immune system over time, which may also help shorten the duration of a cold. Before taking ginseng (or any other supplement), check with your physician to ensure it will not interact with any medications you may be taking — blood thinners, diabetic medications or antidepressants — or have any other adverse health implications. If you have an autoimmune disorder, have had an organ transplant or if you are pregnant, you should not take ginseng supplements. In general, ginseng should not be taken long-term. If you want to take ginseng for a short period of time (no more than 12 weeks) to help prevent a cold, your intake should not exceed 300 mg/day.
Vitamin C
Many cold and flu products feature high doses of vitamin C, however, there is very little research to support that large amounts of vitamin C is an effective way to combat the cold or flu. In fact, vitamin C is water-soluble, so any amount over your body’s daily requirement (90 mg/day for men and 75 mg/day for women) is removed from your body when you urinate. A better way to keep your immune system strong is by eating foods rich in vitamin C such as bell peppers, broccoli, kiwi or strawberries.
Zinc
Zinc is a mineral commonly found in OTC cold supplements, like Zicam or Cold-eeze. While research suggests that it can help alleviate cold symptoms and slightly reduce the duration of your cold, there are a few things you should be aware of. First, it is important to understand that zinc helps to alleviate symptoms, not prevent colds. For best results, you should begin taking zinc supplements the day your symptoms start. After you have been exposed to a virus, zinc works to prevent it from multiplying. Ensuring you are taking the proper dose is also important. In order for it to be effective, products should contain between 13 – 23 milligrams of zinc. Be careful not to take too high of a dose because too much zinc can suppress your immune system. Adults should limit their daily intake to 40 mg/day or less.
Using Combination Cold and Flu Products Safely
Many OTC cold and flu products combine multiple active ingredients into a single medication. While these products can be convenient, it’s important to read labels carefully to avoid taking more than you intend.
Always check labels to avoid:
- Taking more than one product that contains acetaminophen
- Doubling up on decongestants or cough suppressants
If you’re unsure which products can be taken together, your primary care provider can help guide you.
Cold and Flu Treatment During Pregnancy
If you develop a cold or the flu and are pregnant, many OTC medications may be off-limits. To help relieve symptoms safely, consider the following supportive care options:
- Getting plenty of rest
- Increasing your fluid intake
- Drinking hot tea, sucking on ice chips, or gargling salt water for sore throats
- Using a humidifier, taking warm showers, and keeping your head elevated to alleviate congestion
Some OTC medications are safe for you and your baby, including acetaminophen (Tylenol), vapor rubs and certain cough suppressants and decongestants. You should consult with your OB/GYN before beginning any cold or flu medications. If you have questions about what’s safe to take during pregnancy, reach out to your provider for guidance.
Understanding What These Medications Actually Do
Over-the-counter cold and flu medications help manage symptoms like congestion, cough, fever, and body aches. They can make you more comfortable while your body fights off the virus, but they don’t cure the illness or make it go away faster.
Most cold and flu symptoms improve on their own within a week or two. But sometimes what you’re experiencing needs more than symptom relief. If symptoms aren’t getting better after a few days, are worsening instead of improving, or feel more severe than a typical cold or flu, it’s worth checking in with a provider.
You should seek care if you’re dealing with a high or persistent fever, trouble breathing, chest pain, symptoms lasting longer than expected, or if you have a chronic condition that puts you at higher risk. If you’re pregnant or caring for a young child and something feels off, trust that instinct and reach out to your provider.
When it comes cold and flu treatment, Internal Medicine provider Dr. Peter Makar explains, “My approach when patients ask me questions related to this topic is to listen closely to their concerns and take the time to develop effective treatment plans which include a wide range of over-the-counter medications and interventions that are available to my patients. In general, it is better for patients to be evaluated in the office so I can best tailor their care based on my evaluation however I am happy to do virtual visits to accommodate busy schedules. My patients can reach out to me anytime to schedule an appointment if they have any questions or concerns.“
