For Healthcare Professionals
Applies to felodipine: oral tablet extended release
Side effects of felodipine were generally mild and transient. The most common side effects reported with felodipine given at 2.5 to 10 mg per day were peripheral edema and headache. Therapy was discontinued due to adverse drug events in about 6% of patients, primarily for peripheral edema, headache or flushing.
A dose of 20 mg per day has been evaluated in some clinical trials. Although 20 mg per day increased the antihypertensive effect of felodipine, a disproportionate increase in side effects, especially those associated with vasodilatory effects, was reported.[Ref]
Peripheral edema was generally mild, but it was age and dose related. It resulted in treatment discontinuation in about 3% of patients.
Other side effects have included peripheral edema (up to 17.4%), flushing (up to 6.9%), asthenia (up to 3.9%), warm sensation (up to 1.5%), chest pain, facial edema, and influenza-like illness.
Nervous system side effects have included headache (up to 14.7%), dizziness (up to 3.7%), paresthesia (up to 1.6%), syncope, insomnia, and somnolence.[Ref]
Cardiovascular side effects have included palpitation (up to 2.5%), myocardial infarction, hypotension, angina pectoris, arrhythmia, tachycardia, premature beats, and leukocytoclastic vasculitis. A few rare cases of felodipine-induced telangiectasia have been reported.[Ref]
Gingival hyperplasia has been avoided or has regressed with good dental hygiene.[Ref]
Gastrointestinal side effects have included dyspepsia (up to 3.9%), nausea (up to 1.7%), constipation (1.5%), abdominal pain, diarrhea, vomiting, dry mouth, flatulence, and acid regurgitation. Gingival hyperplasia, usually mild, has been reported in less than 0.5% of patients.[Ref]
Respiratory side effects have included upper respiratory infection (up to 3.9%), cough (up to 1.7%), rhinorrhea (up to 1.6%), sneezing (up to 1.6%), dyspnea, pharyngitis, bronchitis, influenza, sinusitis, epistaxis, and respiratory infection.
