Asthma Medications: What You Need to Know

If you or someone you love deals with asthma, knowing which medication does what can feel like a maze. The good news is most asthma drugs fall into just a few categories, and each has a clear purpose—whether it’s stopping an attack fast or keeping symptoms under control day‑to‑day.

Quick‑Relief vs. Long‑Term Control

Quick‑relief (rescue) inhalers are your go‑to when you feel tightness, wheeze or coughing flare up. They contain bronchodilators like albuterol that relax airway muscles within minutes. Keep one handy at home, work and in the car; using it early often prevents a full‑blown attack.

Long‑term control meds work behind the scenes to reduce inflammation and keep attacks from happening. These include inhaled corticosteroids (ICS) such as fluticasone, combination inhalers that pair an ICS with a long‑acting bronchodilator (LABA), and leukotriene modifiers like montelukast.

Choosing the Right Inhaler

Not all inhalers feel the same. Pressurised metered‑dose inhalers (MDI) deliver a spray you need to coordinate with your breath, while dry‑powder inhalers (DPI) require a quick, deep inhale. Your doctor will match the device to your ability to use it correctly—because a medication won’t work if the technique is off.

Ask for a demo the first time you get a new inhaler. Most pharmacies offer a short coaching session, and many videos online show step‑by‑step tricks like the “hold‑and‑breathe” method for MDIs or the proper tongue placement for DPIs.

Common Side Effects & How to Handle Them

Inhaled steroids can sometimes cause a sore throat or hoarse voice. Rinsing your mouth with water and spitting after each use usually prevents that. If you notice oral thrush (white patches), talk to your doctor—sometimes a short course of antifungal medicine is needed.

Rescue inhalers may make you feel shaky or increase heart rate. These sensations are normal and subside quickly, but if they’re severe, let your provider know; a dose adjustment might be required.

When to Switch or Add Medications

If you need your rescue inhaler more than twice a week, it’s a sign your long‑term control isn’t enough. Adding a low‑dose steroid or switching to a combination inhaler can bring symptoms down. Some people also benefit from oral steroids during severe flare‑ups, but those are short courses only.

For exercise‑induced asthma, a quick‑relief inhaler taken 15 minutes before activity often does the trick. In other cases, doctors may prescribe a daily low‑dose steroid plus an as‑needed rescue inhaler.

Practical Tips to Stay On Track

1. Set reminders on your phone for daily controller meds.
2. Keep a spare inhaler in a different bag or at work.
3. Review your technique every few months—small errors add up.
4. Carry a written action plan that lists steps for mild, moderate and severe attacks.

Asthma doesn’t have to control you. By understanding the purpose of each medication, using the right inhaler correctly, and staying on top of your routine, you can keep symptoms in check and enjoy life without constant worry.
