I've been having a fast heart rate between 100 and 120 over the last few days. I'm using a brown inhaler for my asthma and an over-the-counter decongestant because of nasal polyps. Could these meds be causing it? If I stop taking them, how long might it take for my heart rate to go back to normal?

Both your asthma inhaler medication and the over-the-counter decongestant can contribute to an increased heart rate. The bronchodilator medication in your inhaler can cause a temporary increase in heart rate as a side effect. Similarly, decongestants can also stimulate the heart and lead to a faster heart rate. If you stop taking these medications, your heart rate should return to normal within a few hours to a few days, depending on how long you have been taking them and your body's response. It is important to consult with your healthcare provider before making any changes to your medication regimen.
