Overview

Because there’s no cure forthe common cold, the best thing you can do is ease thesymptoms

Over-the-counter (OTC) drugs can help with many different symptoms. However, you likely won’t experience all possible symptoms of the cold during every cold you have. The drug that you choose will depend on your specific symptoms.

Nasal decongestants help unclog acongested nose。They work by narrowing the blood vessels in the lining of your nose so that the swollen tissue shrinks and decreases mucous production. Air can then pass through more easily.

These drugs can also help dry uppostnasal drip

Nasal decongestants are available as pills,nasal sprays, and liquid drops. Generally, they aren’t recommended for children who are 3 years or younger.

Active ingredients used in OTC nasal decongestants include:

  • oxymetazoline nasal (Afrin, Dristan 12-Hour Nasal Spray)
  • phenylephrine nasal (Neo-Synephrine)
  • phenylephrine oral (Sudafed PE, Triaminic Multi-Symptom Fever and Cold)
  • pseudoephedrine (Sudafed)

Coughingactually protects the body by expelling unwanted mucus, microbes, and air. However, the urge to cough is a reflex and can sometimes be triggered unnecessarily.

Cough suppressants can help if a cough is interfering with your daily life or sleep. This is why some doctors recommend you take cough suppressants mostly at bedtime.

These drugs work by blocking the nerve impulse that causes your cough reflex. They can help provide short-term relief from coughing.

The most common OTC cough suppressant is dextromethorphan. It’s the active ingredient in medicines such as:

  • Triaminic Cold and Cough
  • Robitussin Cough and Chest Congestion DM
  • Vicks 44 Cough & Cold

Expectorants help thin and loosen mucus so you can cough it up more easily. This can help your body rid itself of excessive mucus more quickly.

The active ingredient in OTC cough expectorants is guaifenesin. It’s found in Mucinex and Robitussin Cough and Chest Congestion DM.

Antihistaminesblock the release of histamine, which is a natural substance our bodies release when we’re exposed toallergens。Antihistamines may provide some relief of symptoms related to the release of histamine in your body. These can include:

Active ingredients in OTC antihistamines include:

  • brompheniramine (Dimetapp)
  • chlorpheniramine (Sudafed Plus)
  • diphenhydramine (Benadryl)
  • doxylamine, which is one of the three active ingredients inNyquil

The above are considered first generation antihistamines, which may cause drowsiness. Because of this, these antihistamines are often found only in nighttime or PM forms of cold drugs.

Second-generation OTC antihistamines, which don’t cause drowsiness, include:

Some healthcare providers advise against relying on these drugs to treat colds. Antihistamines, while treating the symptoms, don’t remove the virus that causes a cold.
