Special Precautions and Warnings
Heart disease: Methylsynephrine might increase blood pressure and heart rate. In theory, taking methylsynephrine might make heart disease worse.
High blood pressure: Methylsynephrine might increase blood pressure. In theory, taking methylsynephrine might make high blood pressure worse.
Surgery: Methylsynephrine might increase blood pressure and heart rate. In theory, taking methylsynephrine might interfere with surgery by increasing blood pressure and heart rate. Stop taking methylsynephrine at least 2 weeks before surgery.
Irregular heartbeat (heart arrhythmia): Methylsynephrine might increase heart rate. In theory, taking methylsynephrine might make an irregular heartbeat worse.
Medications for asthma (Beta-adrenergic agonists) interacts with METHYLSYNEPHRINE
Methylsynephrine might stimulate the heart. Some medications for asthma can also stimulate the heart. Taking methylsynephrine with some medications for asthma might cause too much stimulation and cause heart problems.
Some medications for asthma include albuterol (Proventil, Ventolin, Volmax), metaproterenol (Alupent), terbutaline (Bricanyl, Brethine), and isoproterenol (Isuprel).
Stimulant drugs interacts with METHYLSYNEPHRINE
Stimulant drugs speed up the nervous system and can cause a jittery feeling and a rapid heartbeat. Methylsynephrine might also speed up the heart. Taking methylsynephrine along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure.
Some stimulant drugs include diethylpropion (Tenuate), epinephrine, phentermine (Ionamin), pseudoephedrine (Sudafed), and many others.
Be cautious with this combination
