Hi, This all could be due to reflux vomiting or severe coughing lead to expel out stomach contents. If she is having asthma then she should be given inhalers like MDI with spacer or rotahaler containing bronchodilators like beta agonists, anticholinergics, corticosteroid etc with other symptomatic treatment like antiallergic(antihistamines or mast cell stabilizers) with regular nebulizers with steam inhalation. You can also give her antiemetic drug before giving any medication so that it won t allow to vomit. To reduce stomach acids,she must avoid oily and spicy foods with fatty diet. You may consult your physician for further advise.
