The Cough and Cold Remedies You Shouldn’t Waste Your Money On

Posted by admin

The common cold and cough are among the most frequent ailments, and the market is flooded with over-the-counter medications promising relief. However, many of these remedies are ineffective, overpriced, or even harmful.1 Here’s a breakdown of some common cough and cold remedies that you may want to reconsider:

Over-the-Counter Cough Syrups

Many cough syrups contain ingredients like dextromethorphan (DXM) that suppress the cough reflex.2 While this may seem appealing, it’s important to note that coughing is a natural defense mechanism that helps clear mucus and irritants from the airways.3 Suppressing this reflex can prolong the illness and lead to complications.4

Furthermore, many cough syrups contain alcohol, which can be harmful, especially for children and individuals with certain medical conditions.5 It’s crucial to consult with a healthcare professional before using any cough syrup, especially for children.

Vitamin C Supplements

While vitamin C is an essential nutrient, there’s little evidence to suggest that taking supplemental vitamin C can prevent or shorten the duration of the common cold. While it may offer some benefits for individuals with specific deficiencies, it’s generally not a worthwhile investment for most people.

Zinc Lozenges

Zinc lozenges have been promoted as a potential remedy for the common cold.6 However, studies have yielded mixed results, and the effectiveness of zinc lozenges remains uncertain.7 Additionally, excessive zinc intake can lead to side effects like nausea, vomiting, and a metallic taste in the mouth.8

Nasal Sprays and Drops

Nasal sprays and drops can provide temporary relief from congestion, but prolonged use can lead to rebound congestion, making symptoms worse in the long run.9 It’s essential to use these products as directed and for a limited duration.

Expectorants

Expectorants are medications that help loosen mucus in the lungs, making it easier to cough up.10 While they may be helpful for some individuals, they are not always necessary. In many cases, drinking plenty of fluids and using a humidifier can be just as effective, if not more so.

When to Seek Medical Attention

While most colds and coughs resolve on their own, it’s important to seek medical attention if you experience any of the following symptoms:

  • High fever
  • Severe headache
  • Difficulty breathing11
  • Chest pain12
  • Persistent cough
  • Green or yellow mucus13
  • Sore throat that lasts more than a week

Effective Home Remedies for Cough and Cold

Here are some effective home remedies that can help alleviate symptoms of the common cold and cough:

  • Rest: Get plenty of rest to allow your body to recover.
  • Hydration: Drink plenty of fluids, such as water, broth, or herbal tea, to keep your body hydrated.
  • Humidifier: Use a humidifier to add moisture to the air, which can help soothe irritated airways.14
  • Warm Liquids: Sip on warm liquids like tea or broth to soothe a sore throat.15
  • Salt Water Gargle: Gargle with warm salt water to help relieve a sore throat.16
  • Over-the-Counter Pain Relievers: Use over-the-counter pain relievers like acetaminophen or ibuprofen to reduce fever and alleviate aches and pains.17

By understanding the limitations of over-the-counter remedies and focusing on effective home remedies, you can alleviate the symptoms of a cold or cough and promote a quicker recovery.
