Propranolol.

Propranolol can be prescribed by your health care provider if you have some types of tumor, abnormal heart rhythms, high blood pressure, heart disease, or even certain types of tremor. It lowers your blood pressure by relaxing the blood vessels. Make sure you notify your health care provider of any contraindications you have, such as allergies to any drugs or pregnancy. If you have certain medical conditions (diabetes, liver disease, severe allergies, thyroid problems, heart disease, kidney disease, or lung disease) your dose may need to be adjusted, your doctor will want to monitor you for side effects or additional tests may be required to establish the safety of propranolol. Let your doctor know if you are taking any drugs known to interact with propranolol – such as ACE inhibitors, blood thinners, non-steroidal anti-inflammatory drugs, MAO inhibitors, isoproterenol, amiodarone, antidepressants, dobutamine, haloperidol, heart medications, or clonidine. Side effects of propranolol are common and there is no need to report them unless they change in intensity or get bothersome. The following ones are sometimes possible: lightheadedness, upset stomach, constipation, vomiting, diarrhea, dizziness, difficulty sleeping, rash, and excessive tiredness.
