Cenforce 25 mg (or sildenafil citrate), but certain foods and drinks can affect how well the medication works: Foods and Drinks to Be Cautious With: Fatty or Heavy Meals: Eating a large, high-fat meal may delay the absorption of Cenforce 25 mg. This can slow down how quickly the medication takes effect. It’s best to avoid heavy, greasy meals right before taking the pill. Grapefruit: Grapefruit and grapefruit juice can interfere with the enzymes that metabolize sildenafil, leading to increased blood levels of the drug. This could increase the risk of side effects, so it’s best to avoid grapefruit products while using Cenforce. What’s Fine to Eat: Light Meals: A light meal should not interfere with the medication's effectiveness, so you can eat a balanced meal without worrying. Vegetables, Fruits, and Lean Proteins: Foods like vegetables, fruits, and lean proteins are fine and will not affect how Cenforce works.
