Over-the-Counter Inhalers: What You Can Use and What to Watch For

Looking for quick relief from a stuffy nose or congestion? Not all inhalers are the same. Many inhalers for asthma and COPD need a prescription, but you’ll find several over-the-counter (OTC) options that help with nasal congestion, steam inhalation, and aromatherapy. This guide helps you pick the right OTC choice and avoid common mistakes.

Types of OTC inhalers and how they help

Here are the most common OTC options and what they do:

Medicated nasal sprays (like oxymetazoline): work fast to shrink swollen nasal tissue and clear a blocked nose. They’re great for short-term relief, but don’t use them more than 3 days in a row—longer use can cause rebound congestion.

Saline sprays and rinses: plain saltwater sprays or neti pot rinses loosen mucus and flush irritants. Safe for most people, including pregnant women, and useful daily during allergies or colds.

Aromatic inhalers and vaporizers (menthol, eucalyptus): these give a cooling, open-air sensation. They don’t reduce inflammation but can make breathing feel easier for a while.

Portable steam inhalers: warm steam helps loosen mucus in the nose and throat. Good for congestion and sinus discomfort, but use carefully to avoid burns.

Herbal or balm inhalers: contain essential oils or menthol blends. Some people find them soothing, but check for allergies and avoid use around young children or pets.

How to use OTC inhalers safely

Read the label every time. Check age limits, dosing, active ingredients, and warnings. If a product says don't use for more than a few days, follow that. For medicated nasal sprays, limit use to 3 days to avoid rebound congestion. Saline is safe for longer use and is a good first step.

Have high blood pressure, heart disease, or you’re pregnant? Talk to your pharmacist or doctor before using medicated decongestants. If you’re pregnant, see our guide “Pregnancy and Decongestants” for specifics on safe choices.

If symptoms include wheeze, chest tightness, shortness of breath, or fever, you might need a prescription inhaler or medical care. OTC products won’t treat asthma or COPD. For alternatives to prescription inhalers like Symbicort, check our “Best Symbicort Alternatives 2025” piece and talk to your clinician before switching meds.

Finally, don’t share inhalers, keep them clean, and toss expired products. If an OTC product hasn’t helped in a few days or makes symptoms worse, get medical advice.
