855-85-PULSE

Once you have a diagnosis for your respiratory illness, the next question is always: What can I actually do to feel better? When it comes to the “tripledemic,” treatment options vary dramatically. Crucially, the best treatments for flu and COVID must be started quickly to be effective, while RSV treatment focuses entirely on symptom management.

Treatment: What Actually Works

Wherever you look online, you probably see wellness influencers talking about the best ways to kick your cold/flu/[insert illness here]. Let’s talk evidence-based treatment instead:

For Flu: Tamiflu reduces duration by 1-2 days if started within 48 hours. It is worth considering for high-risk patients or those with severe symptoms. Be aware that side effects (like nausea) are sometimes worse than the flu itself.
For COVID: Paxlovid is highly effective but has significant drug interactions. It’s recommended for anyone over 65 or with other risk factors. The metallic taste is real and awful but temporary, and a rebound happens in about 20% of cases, though it is usually milder.
For RSV: Unfortunately, there is no antiviral treatment available. The approach is supportive care only: fluids, rest, and humidity. Albuterol inhalers help some adults with wheezing. Antibiotics are useless unless a secondary bacterial infection is present.

For All Three, Supportive Care is Key

It sounds trite, but rest, hydration, and comfort are

Rest: This means sleeping as much as you can, and resting (your body and your brain!)
Hydration: Stick to water, electrolyte beverages, and decaffeinated war, beverages Avoid alcohol and caffeine, as they can both exacerbate dehydration.
Use fever reducers as needed: Alternate tylenol and ibuprofen for maximum relief.
Natural cough remedies:
- Honey is more effective than most cough syrups. Recent studies have shown that over-the-counter cough medicines containing dextromethorphan do not actually work all that well.
- A humidifier is your best weapon against that lingering cough. Moist air soothes irritated airways, loosens mucus, and makes your cough more productive.

Your Survival Game Plan

Regardless of what respiratory virus is getting you down, these are the steps you should take to minimize your symptoms and reduce the likelihood of secondary infections:

If you feel something coming on: Get tested within 48 hours.
If positive for flu or COVID: Start antivirals immediately if eligible.
Isolate properly: Five days minimum, or until fever-free for 24 hours.
Monitor symptoms: Don’t assume improvement means you’re cured.
