Drug Interaction Report

Using salmeterol together with methylene blue may increase cardiovascular side effects such as heart palpitations, chest pain, increased heart and pulse rates, and blood pressure elevations. The risk exists even when salmeterol or similar medications are given by oral inhalation directly into the lungs, and more so if these products are overused. Talk to your doctor before using these medications if you have a history of heart disease or high blood pressure. Depending on your condition, it may be preferable to wait at least 14 days after you are off methylene blue before you start using salmeterol. Do not exceed the dose and frequency of use of salmeterol recommended on the product label or prescribed by your doctor. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
