Drug interactions between lisinopril and prazosin
Interactions between your drugs
Applies to: prazosin and lisinopril
Using prazosin and lisinopril together can have increased effects on your blood pressure. You may be more likely to experience side effects such as dizziness, weakness, headache, flushing, fainting, and irregular heartbeat, especially if you have been on lisinopril and are starting treatment with prazosin. These effects may also occur following a dose increase of prazosin or when prazosin is restarted after an interruption. Let your doctor know if you develop these symptoms and they do not go away after a few days or they become troublesome. You may need a dose adjustment or more frequent monitoring of your blood pressure to safely use both medications. Taking the prazosin dose just before going to bed may help. Avoid driving or operating hazardous machinery until you know how these medications affect you, and use caution when getting up from a sitting or lying position. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
