- Fever

Key Ingredients and Their Functions
OTC cold and flu medicines typically combine several active ingredients to address multiple symptoms․ Here’s a breakdown of common ones:
Pain Relievers and Fever Reducers
These are essential for managing aches, pains, and fever․ Common options include:
- Acetaminophen (Tylenol): Effective for reducing fever and relieving mild to moderate pain․ It’s generally well-tolerated but can cause liver damage in excessive doses․
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Such as ibuprofen (Advil, Motrin) and naproxen (Aleve)․ These reduce fever, relieve pain, and also help reduce inflammation․ They can cause stomach upset and should be used with caution by individuals with certain medical conditions․
Decongestants
These help to relieve a stuffy nose by shrinking swollen blood vessels in the nasal passages․
- Pseudoephedrine (Sudafed ౼ behind the counter in many regions): A powerful decongestant, but its sale is often restricted due to its use in the illegal manufacture of methamphetamine․
- Phenylephrine (Sudafed PE ‒ OTC): A less potent decongestant that is widely available over the counter․
Cough Suppressants
These medications help to reduce the urge to cough, particularly useful for dry, hacking coughs that interfere with sleep․
- Dextromethorphan (DM): A common cough suppressant found in many OTC cold medicines․
Expectorants
These help to thin mucus, making it easier to cough up phlegm from the lungs․ They are beneficial for chesty, productive coughs․
- Guaifenesin (Mucinex): The most common expectorant․ It’s important to drink plenty of water when taking guaifenesin to help it work effectively․
Antihistamines
While primarily used for allergies, some antihistamines are included in cold medicines to help with runny noses, sneezing, and to promote sleep due to their sedating effects․
- First-generation antihistamines (e․g․, diphenhydramine, chlorpheniramine): Can cause drowsiness․
- Second-generation antihistamines (e․g․, loratadine, cetirizine): Less likely to cause drowsiness․
Choosing the Right Medicine for Your Symptoms
The best approach is to target your most bothersome symptoms:
- For a stuffy nose and body aches: Look for a combination product with a decongestant and a pain reliever/fever reducer․
- For a dry cough and sore throat: A medicine with a cough suppressant and a pain reliever might be best․
- For a chesty cough: An expectorant combined with a pain reliever can help clear mucus․
- For sneezing and runny nose (especially if allergy-like): A medicine containing an antihistamine might offer relief, but be mindful of potential drowsiness․
When to See a Doctor
While OTC medications can provide relief, it’s important to consult a healthcare professional if:
- Your symptoms are severe or worsening․
- You have a high fever (over 103°F or 39․4°C)․
- You experience shortness of breath or difficulty breathing․
- Your symptoms persist for more than 7-10 days․
- You have underlying health conditions (e․g․, asthma, heart disease, diabetes)․
Always read and follow the dosage instructions on the medication label carefully․ If you are unsure about which medication is best for you, speak with a pharmacist or your doctor․
