Brief Answer: risk increased blood sugar and triglycerides Detailed Answer: HI, thanks for using healthcare magic There is a risk of minor interaction between hydralazine and metoprolol. It is thought that the combination may potentially lower the blood pressure more than expected. If the blood pressure is lower than it should be then you may experience dizziness, faintness, increased heart beat. You can monitor the blood pressure. In addition the use of these two types of medication in combination can also cause an increase in blood sugar and triglyceride levels in some persons but this risk is greater if there is a risk of diabetes. You may not experience any side effects associated with the use of the medication together. Summary: risk of very low blood pressure and increase blood sugar and triglycerides I hope this helps, feel free to ask any other questions
