The drug salmeterol ticapone, although better, but if you do not master the method of use, not only wastes the drug, but also leads to ineffective treatment. For details on how to use the device, see the instructions. The following is mainly to tell you about the mistakes that other people often make, I hope to avoid the following mistakes: 1. will not be on the drug: not open the shell, that is, not open the lid; not pull open the sliding lever, not the drug capsule open; repeatedly toggle the sliding lever, resulting in the opening of multiple capsules, resulting in drug waste. Inhalation action and pulling open the sliding lever action at the same time, which is not conducive to inhaling the drug. 2. Not being able to inhale the drug: some patients exhaled into the suction nozzle and blew the drug powder out of the container, reducing the amount of drug inhaled into the lungs; some patients blocked the suction nozzle with their tongues and were unable to inhale the drug into the lungs; the inhalation time was too short and the amount of drug entered the lungs less; the powder just inhaled into the lungs was exhaled out of the body again without holding the breath for 10 seconds after inhalation. 3. Not rinsing the mouth in time after inhalation, resulting in the adsorption of the drug at the throat, causing hoarseness or mycotic infection; 4. Pouring out the drug and taking it orally, the effective dose entering the lungs is too small, but the amount of hormone entering the blood increases, resulting in increased side effects. 5. Not spitting out the mouthwash after gargling, which will cause side effects of hormones in the long run. Precautions: Use the medication according to the instructions as shown, or consult a physician or pharmacist. Rinse the mouth and throat with clean water after inhalation to prevent the growth of fungus. Do not swallow the cleaning solution.
