Blood Pressure Home > Prinzide Side Effects
In clinical trials of Prinzide, side effects that were most commonly reported with the medication included dizziness, headache, cough, and fatigue. Other potential side effects of Prinzide include such things as diarrhea, indigestion, and elevated potassium levels in the blood. Although they are less common, serious side effects can occur while taking Prinzide, such as unexplained swelling of the head or face.
As with any medicine, there are possible side effects with Prinzide® (lisinopril-hydrochlorothiazide). However, not everyone who takes the medicine will experience side effects. If Prinzide side effects do occur, they are generally mild and either require no treatment or can easily be treated by you or your healthcare professional. Serious side effects are less common.
(The side effects discussed below are not a complete list of side effects reported with Prinzide. Your healthcare provider can discuss a more complete list of Prinzide side effects with you.)
Prinzide has been studied extensively in clinical trials for people with high blood pressure. In these studies, side effects are always documented and compared to problems that may have been experienced by a similar group of people not taking the medicine. In these studies, the most common Prinzide side effects included:
- Dizziness -- reported in up to 7.5 percent of people
- Headache -- reported in up to 5.2 percent of people
- Cough -- reported in up to 3.9 percent of people
- Fatigue -- reported in up to 3.7 percent of people
- Dizziness, lightheadedness, or fainting when standing from a sitting or lying down position (known medically as orthostatic effects) -- reported in up to 3.2 percent of people.
Other side effects of Prinzide (occurring in more than 1 percent of people) include, but are not limited to:
- High potassium levels in the blood
- Upper respiratory infection, such as the common cold or flu
- Low blood pressure
- Erectile dysfunction, also known as ED or impotence (see Lisinopril Sexual Side Effects).
