Amlodipine Appetite & Cravings Changes: What Patients and Clinicians Need to Know

Does amlodipine increase appetite?

No. What the label lists for appetite is the opposite: anorexia, plus weight gain and weight decrease, among events seen in more than 0.1% and less than 1% of patients [1].

The label separates adverse events by how closely they were tied to the drug. Edema, dizziness, flushing and palpitation are dose related and tabulated by dose [1]. Fatigue (4.5% vs 2.8% on placebo), nausea (2.9% vs 1.9%) and abdominal pain (1.6% vs 0.3%) occurred above 1% without a clear dose relationship [1]. Below that sits a list of events seen in more than 0.1% and less than 1% of patients, where the label says a causal relationship is uncertain. That list includes anorexia, weight gain, weight decrease and thirst [1].

What the edema numbers say about weight

Edema is the label's most common adverse reaction, and its reported rate climbs with dose: 1.8% at 2.5 mg, 3.0% at 5 mg and 10.8% at 10 mg, against 0.6% on placebo [1]. It was reported more often in women, 14.6% versus 5.1% on placebo, than in men, 5.6% versus 1.4% [1].

Swelling is fluid, so it can change the number on a scale without any change in eating. Weight gain and weight decrease appear in the label's low-frequency group with uncertain causality, while edema has separately reported, dose-related rates [1].

What the label says about mechanism and related symptoms

The label describes amlodipine as a peripheral arterial vasodilator that lowers peripheral vascular resistance, with a gradual onset of effect. It does not describe an appetite or craving effect [1]. Nausea (2.9% vs 1.9% on placebo) is listed among the more common effects, and thirst appears in the low-frequency group [1]. The label also reports no clinically relevant changes in serum glucose, triglycerides, total cholesterol or HDL cholesterol in routine laboratory tests [1].
