Salbutamol is a fast‑acting bronchodilator that many people with asthma or COPD rely on to open up their airways. When you feel short of breath, a puff of a salbutamol inhaler can bring quick relief. It works by relaxing the muscles around the lungs, letting more air flow in and out. If you’ve never used it before, the basics are simple: inhale, hold for a few seconds, then breathe out. That’s all you need to know to get the medicine where it belongs.
Most adults use 1‑2 puffs (100‑200 µg each) every 4‑6 hours as needed. Some doctors prescribe a regular schedule for people with frequent symptoms, like two puffs twice a day. Children get lower doses, usually one puff every 4‑6 hours, but always follow the doctor’s exact instructions. The key is not to exceed the maximum daily limit—usually 8–12 puffs—because too much can cause shaky hands, fast heartbeat, or a sore throat.
Most users feel fine, but a few might notice a tremor, headache, or a racing heart. Those symptoms usually fade once the medicine settles. If you get chest pain, severe palpitations, or a rash, stop using it and call a health professional right away. Keep an eye on how often you need a puff; needing it more than twice a day could mean your asthma isn’t under control and you might need a different treatment plan.
Because salbutamol works fast, it’s a “rescue” inhaler—not a daily controller. For long‑term asthma control, doctors often prescribe inhaled steroids or long‑acting bronchodilators. Using salbutamol too often can mask the need for these preventive medicines, so ask your doctor if you’re unsure about your treatment balance.
If you’re buying salbutamol online, stick to reputable pharmacies that require a prescription. Check that the site shows a valid pharmacy license and clear contact details. Compare prices, but don’t sacrifice safety for a lower cost—counterfeit inhalers can be dangerous. Some UK pharmacies even offer free delivery for a quick refill, which can be handy if you run out unexpectedly.
Storing your inhaler properly extends its life. Keep it at room temperature, away from direct heat or moisture. Most inhalers have a dose counter; when it reaches zero, replace the device even if the medication looks fine. A dead inhaler won’t give you the right dose when you need it most.
Finally, practice your technique. A common mistake is not shaking the inhaler before use, which can result in an uneven dose. Also, exhale fully before inhaling the medication, then hold your breath for about 10 seconds to let the drug settle in the lungs. If you’re using a spacer, attach it correctly and breathe in slowly.
Understanding salbutamol, its proper use, and the signs of trouble can keep you breathing easy and confident. Keep your inhaler handy, follow the prescribed dose, and stay in touch with your doctor to make sure your asthma plan stays on track.
