the drug you have mentioned is a beta2-adrenergic agonist and it can cause bronchodilation in asthmatics and can also burn fat. it has other side effects also such as it can cause tremors increased heart rate high blood pressure muscle cramps and can also alter potassium level in your body. so it is better to avoid it. i would recommend you to go with natural ways of weight reduction. since you are already taking anti-asthma drugs there is no need of taking this drug. you can take other short acting beta2-adrenergic agonist as required. for further information consult an internal medicine physician online --> <link>
