Best Cold Medicine for Adults To Treat Symptoms Quickly


When a cold strikes, you want fast, effective relief. And while grabbing the first over-the-counter cold medication seems like an easy solution, there’s no one-size-fits-all remedy. Doctors note that the best cold medicine for adults depends on your symptoms. Here, all you need to know about cold and flu medications, plus which options are the most effective.

How to determine the best cold medicine for adults 

Many people typically “get relief from a combination of over-the-counter (OTC) medications, which can include a decongestant (like pseudoephedrine or phenylephrine), an antihistamine (like diphenhydramine, which helps with sneezing and runny nose) and a pain reliever/fever-reducing medication (like acetaminophen or ibuprofen),” says Brynna Connor, MD, Healthcare Ambassador at NorthWestPharmacy.com. 

If your symptoms are mild, targeted single-ingredient medications might suffice,” says Jennifer Bourgeois, PharmD, a health expert at Single Care Pharmacy. “But a multi-symptom cold medicine like DayQuil or NyQuil may be best for multiple severe symptoms.” 

Worth noting: Cold medicines only help manage symptoms; they don’t cure the cold itself. Dr. Connor says rest and fluids are just as important as medication.

Pseudoephedrine vs phenylephrine​ for cold relief

 

When choosing an OTC cold medication, two of the most common ingredients you’ll find are pseudoephedrine and phenylephrine. If you’re dealing with a severe cold, always go with pseudoephedrine, as it’s more effective in reducing congestion, says Gustavo Ferrer, MD, FCCP, pulmonologist and medical health advisor at Ferrer Pulmonary Institute. (Note: You’ll need to show I.D. when purchasing, as the medication is either kept behind the pharmacy counter or requires age verification at checkout.)

Dr. Connor adds that pseudoephedrine, which is found in medications like Sudafed, is not metabolized in the gut wall. That means that nearly 100 percent of the medication reaches the bloodstream, enabling it to work longer and harder. “Comparatively, phenylephrine [sold as Sudafed PE] is only affected when taken via nasal spray and the gut wall metabolizes it, so a lesser percentage (approximately 40 percent) of the medication reaches the bloodstream.”

In fact, the Food and Drug Administration (FDA) announced in November 2024 that it proposed an order to remove oral phenylephrine from OTC medications, as it was found to be ineffective. (Learn more about alternatives to phenylephrine here.)

The best cold medicine for adults based on your symptoms

While pseudoephedrine is a smart pick if you’re experiencing multiple, severe symptoms, what should you reach for if you have a minor cold or just one or two stubborn symptoms? We break down the experts’ top picks:

Stuffy nose? Use a decongestant

Sniffles and stuffiness go hand in hand with the common cold. “An oral decongestant like pseudoephedrine (Sudafed) can help,” says Dr. Connor. “Nasal sprays like oxymetazoline [Afrin] are also effective, but they should only be used for three days max, as overuse can worsen congestion.”

Runny nose? Use an antihistamine

Dr. Ferrer explains that antihistamines like chlorpheniramine [Comtrex Cold] or diphenhydramine [Benadryl] help dry up a runny nose. Sometimes, cold medications combine these ingredients to help minimize congestion and extra mucus.

Sore throat or cough? Use a suppressant

When you have a sore throat, Dr. Connor advises keeping lozenges on hand as a first step. For added relief, there are also two different routes for treating a cough: “dextromethorphan (Robitussin) is a good option if you need to suppress it, while guaifenesin (Mucinex) can help loosen mucus if you have a productive cough,” explains Dr. Connor.

“If you’re not familiar with the difference between a cough suppressant and an expectorant, a cough suppressant (also known as an antitussive) will reduce the frequency and/or intensity with which you cough by blocking the cough reflex,” Dr. Connor says. “An expectorant is a medicine designed to thin the mucus in the throat and lungs, making it easier to cough up.” 

Fever or body aches? Use a pain reliever

“Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) are best for reducing fever and easing body aches,” says Dr. Connor. These are safe and easily accessible options for most people.

Bourgeois says there are things to remember when choosing medication for cold relief. Here, her advice:

  • Avoid duplicate active ingredients by checking the labels to reduce overdose risks (e.g., taking acetaminophen from multiple products).
  • Consult your pharmacist or healthcare provider to ensure these medications are safe and appropriate, especially if you take other prescriptions or have underlying health conditions.
  • Stay hydrated to thin mucus and relieve congestion naturally.

You can also try natural cold remedies such as steam inhalation, drinking tea, using humidifiers or neti pots or simply resting to complement OTC or prescription treatments.  Also, if your symptoms persist beyond three to five days of medication and you’re not seeing improvement, it’s best to consult your doctor.
