Lisinopril-hydrochlorothiazide 10 mg/12.5 mg is a combination medication used to treat high blood pressure [1]. Common side effects include dizziness, cough, headache, and fatigue [2].
What are the main side effects of lisinopril-hydrochlorothiazide?
The most frequently reported side effects of lisinopril-hydrochlorothiazide involve the cardiovascular and central nervous systems [2]. Patients commonly experience dizziness, particularly when standing up, due to the blood pressure-lowering effect of the medication [2]. A dry cough is also a known side effect, often attributed to the lisinopril component [2]. Headaches and fatigue can occur as the body adjusts to the medication [2]. Other potential side effects include nausea, diarrhea, and electrolyte imbalances, such as low potassium levels [1][2].
Are there serious side effects to watch for?
While less common, serious side effects can occur. These include angioedema, a swelling of the face, lips, tongue, or throat, which can be life-threatening and requires immediate medical attention [1]. Kidney problems can also develop, especially in individuals with pre-existing kidney disease [1]. Serious allergic reactions, including rash and difficulty breathing, are possible [1]. Patients should contact their doctor immediately if they experience any of these severe reactions [1].
How does lisinopril-hydrochlorothiazide work?
Lisinopril is an ACE (angiotensin-converting enzyme) inhibitor that works by relaxing blood vessels, which lowers blood pressure [1]. Hydrochlorothiazide is a diuretic that helps the body get rid of excess salt and water, also contributing to lower blood pressure [1]. Together, they provide a dual mechanism for managing hypertension [1].
When does patent protection for lisinopril-hydrochlorothiazide expire?
