SIDE EFFECTS

Adverse Experiences

The incidence of adverse events during treatment with Adalat CC in doses up to 90 mg daily were derived from multi-center placebo-controlled clinical trials in 370 hypertensive patients. Atenolol 50 mg once daily was used concomitantly in 187 of the 370 patients on Adalat CC and in 64 of the 126 patients on placebo. All adverse events reported during Adalat CC therapy were tabulated independently of their causal relationship to medication.

The most common adverse event reported with Adalat CC was peripheral edema. This was dose related and the frequency was 18% on Adalat CC 30 mg daily, 22% on Adalat CC 60 mg daily and 29% on Adalat CC 90 mg daily versus 10% on placebo.

Other common adverse events reported in the above placebo-controlled trials include:

Flushing/heat sensation 4 0
