Fildena Chewable 100 mg, like other medications containing sildenafil citrate, is generally safe and effective for most men with erectile dysfunction (ED). However, there are specific populations that should exercise caution or avoid using this medication altogether. These populations include:

Individuals with cardiovascular disease: Since sildenafil citrate can increase blood flow, it may put added strain on the heart. Individuals with a history of heart disease, heart attack, stroke, or unstable angina should consult their healthcare provider before using Fildena Chewable 100 mg.

Those taking nitrates or nitric oxide donors: Combining sildenafil citrate with nitrates or nitric oxide donors (often prescribed for chest pain or heart conditions) can cause a severe drop in blood pressure, leading to dizziness, fainting, or even a heart attack. It's crucial to inform your doctor of all medications you are taking, including over-the-counter and herbal supplements, to avoid potential interactions.

People with liver or kidney impairment: Individuals with severe liver or kidney disease may have difficulty metabolizing and excreting sildenafil citrate, leading to an increased risk of side effects. A lower dosage or alternative treatment may be necessary in these cases.
