Other medicines and atenolol cinfa

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them. Some medicines can affect the action of others, in particular, tell your doctor if you are using:

• Disopyramide or amiodarone (for irregular heartbeats).
• Other treatments for high blood pressure or angina (in particular, verapamil, diltiazem, nifedipine, clonidine). If you are using clonidine for high blood pressure or to prevent migraines, do not stop treatment with it or with atenolol without consulting your doctor first.
