Home care for RSV: what actually helps
There is no antiviral medication approved to treat RSV in infants. Treatment is supportive — helping the baby stay comfortable, hydrated, and breathing easily while the virus runs its course. The good news is that several simple interventions genuinely help. Here's what to do and what to skip.
What helps
Saline nasal drops and suctioning
This is the most effective thing you can do at home. Nasal congestion makes it harder for infants to breathe and feed (infants are obligate nose breathers — they can't switch to mouth breathing the way older children can). The sequence:
- Apply 2–3 drops of saline to each nostril (or a small spray)
- Wait 30–60 seconds for the saline to loosen secretions
- Suction with a nasal aspirator — a bulb syringe or a NoseFrida-style aspirator
- Do this before feeds and before sleep, or whenever congestion seems to be interfering with breathing or eating
The NoseFrida (a tube-based oral aspirator) is more effective than standard bulb syringes for most parents. The parent's mouth provides suction through a filter — there is no risk of the parent catching the virus from this.

Humidity
Moist air helps keep the airways from drying out and makes secretions easier to clear. Run a cool-mist humidifier in the baby's room during sleep. Use distilled or filtered water and clean the humidifier regularly to prevent mold.
Cool-mist is preferred over warm-mist for infant safety (no burn risk). Avoid placing the humidifier too close to the crib — a few feet away is enough.
Hydration
Keep offering feeds frequently, even if your baby is eating less than usual. Sick infants may feed for shorter periods due to congestion and fatigue. More frequent, shorter feeds are better than pushing for full normal-sized feeds. Signs of adequate hydration: wet diapers every 3–4 hours, tears when crying. If your baby hasn't had a wet diaper in 6 hours, call your pediatrician.
Positioning
Elevating the head of the mattress slightly (place a rolled towel under the head end of the mattress pad, not inside the crib) may help with drainage — but keep safety in mind. Never use a pillow or wedge inside the crib for infants under 12 months. For supervised awake time, holding the baby upright on your chest helps drainage.
Fever management
For fever above 100.4°F in infants 3 months and older: acetaminophen (Tylenol) or ibuprofen (only for infants 6 months and older) can be used for comfort per the dosing on the package, adjusted for your baby's weight. Do not use ibuprofen under 6 months. Do not use aspirin. Fever itself is not harmful in most cases — it's a sign the immune system is working. Treat it if your baby seems uncomfortable, not automatically for any number.
Any fever in an infant under 3 months requires an immediate call to your pediatrician or ER visit — regardless of the number, regardless of whether RSV is suspected. This is an emergency threshold, not a comfort decision.
Monitoring oxygen at home
A pulse oximeter clips to a finger or toe and shows SpO₂ (blood oxygen saturation). Helpful to have during RSV season if you have a young infant. Normal is 97–100%. If readings are consistently below 95%, call your pediatrician. Below 90%: go to the ER.
What doesn't help (and what to skip)
- Antibiotics: RSV is a virus. Antibiotics do nothing against it. They may be prescribed if a bacterial secondary infection develops (like an ear infection), but not for RSV itself.
- Over-the-counter cold medications: Not recommended for infants or children under 4. Decongestants, antihistamines, and cough suppressants are not effective for infants and carry risks.
- Honey: Effective for cough in children over 1 year — not appropriate for infants under 12 months due to botulism risk.
- Steroid nebulizers: The evidence for nebulized epinephrine or steroids in RSV bronchiolitis is weak. Some emergency settings use them in severe acute presentations, but routine home use is not recommended.
- Chest percussion or thumping: This is not recommended for RSV. It doesn't help clear lower airway mucus in infants and can cause discomfort.
When home care is no longer enough
Stop home management and seek care if:
- Breathing is labored — ribs showing, nostrils flaring, grunting
- SpO₂ below 95% that doesn't recover
- Your baby hasn't had a wet diaper in 6 hours
- Eating less than half of normal for more than two feeds in a row
- Fever returns after improving, or a new fever develops after day 5
- Your instinct says something is wrong
