If your doctor suggested moving from Symbicort (budesonide + formoterol) to Advair (fluticasone + salmeterol), you probably want to know what changes to expect and how to stay safe. These are both combination inhalers used for asthma and COPD, but they act differently and use different devices. I’ll keep this simple and practical so you can have a smooth switch.
First, the active medicines differ. Symbicort combines an inhaled steroid (budesonide) with formoterol, a fast-onset long-acting bronchodilator. Advair pairs fluticasone with salmeterol, which takes a bit longer to start working. That means rescue feel and timing can change slightly after you switch. Also, inhaler devices may look and feel very different — don’t assume the same technique works for both.
Another practical point is dosing style. Both are usually used twice daily for maintenance, but how your symptoms respond can vary. In some countries, formoterol-containing inhalers are approved for both regular use and as-needed symptom relief; salmeterol-containing inhalers usually aren’t. Your prescriber will choose the right approach for you.
Always check with the prescriber or pharmacist before changing. They’ll confirm the correct dose and write the new prescription. You generally don’t need to taper steroids when swapping inhaled corticosteroids, but you must watch your symptoms closely for the first 1–2 weeks. Keep your quick-relief inhaler (albuterol/salbutamol) handy until you’re confident the new inhaler controls symptoms.
Learn the new device right away. Ask the pharmacist to show you how to load, inhale, and clean it. A change in technique is a common reason people feel worse after switching. Use a spacer if your provider recommends one — spacers can improve drug delivery especially if you struggle with coordination.
Monitor side effects and control. Watch for increased coughing, wheeze, or shortness of breath. Also note common inhaled steroid effects like hoarseness or thrush (white patches in the mouth). If symptoms get worse or you need your rescue inhaler more often, call your clinician — don’t wait.
Finally, consider practical factors: cost, insurance coverage, and generic availability. Both drugs have generic versions in many places, but prices and copays can differ. If cost is an issue, ask your provider about equivalent doses or patient assistance options.
Switching inhalers can be straightforward if you plan it with your healthcare team, learn the new device, and track how you feel. If anything feels off, contact your prescriber quickly — better safe than sorry.

As a migraine sufferer, I was intrigued to learn about the potential connection between Losartan and migraine prevention. Losartan, typically used to treat high blood pressure, has shown promise in reducing the frequency and severity of migraine headaches. This medication works by blocking a substance in the body that causes blood vessels to constrict, which is known to trigger migraines. While more research is needed, Losartan could potentially offer relief for those struggling with chronic migraines. As always, it's essential to consult with a medical professional before trying any new treatments.
In a recent blog post, I discussed the link between high eye pressure and glaucoma, a potentially blinding eye disease. I learned that high eye pressure, also known as ocular hypertension, can damage the optic nerve and lead to glaucoma. It's important to have regular eye exams to detect any changes in eye pressure early on. While not everyone with high eye pressure will develop glaucoma, it is still a significant risk factor. Therefore, it's essential to be proactive in managing eye pressure and maintaining overall eye health.
