Daily Life Interactions for Flecainide Acetate 100mg Tablet

Elements of your daily lifestyle may have an effect on the medications you are taking. Drug interactions can result in unwanted side effects, reduce the effectiveness of your medicine or possibly increase the action of a particular medicine.

Moderate Lifestyle Interaction
Tobacco and Flecainide Acetate 100mg Tablet(Flecainide Acetate)
Tobacco and Flecainide Acetate(Flecainide Acetate)
In theory, Tobacco smoking may reduce the effectiveness of Flecainide, because tobacco smoke contains substances that speed the removal of Flecainide from the body. Also, Tobacco smoking may increase the blood pressure or contribute to the risk of heart disease and related problems. Alternatively, if you take Flecainide and suddenly stop Tobacco smoking, you may experience increased or worsening side effects of Flecainide, such as nausea, headache, tremor or heart-related side effects. Make sure your prescriber is aware that you smoke Tobacco or if you plan to stop smoking. Contact your prescriber immediately if you experience chest pain, palpitations, dizziness, fainting or falling spells, shortness of breath, or change in your usual heart beat (fast, slow, or irregular heart beat) while taking Flecainide.
