2. Severe Cardiovascular Conditions: Individuals with unstable angina, severe heart failure, or those who have had a recent heart attack should not use this medication.

3. Hypersensitivity: If you have a known allergy to Fildena Double 200 mg or any other ingredients in the formulation, you should avoid it.

4. Severe Liver or Kidney Impairment: Those with significant liver or kidney issues may require dosage adjustments or should avoid the medication entirely.

5. Low Blood Pressure: Individuals with a history of hypotension should not use this medication.

6. Vision Problems: Those with a history of non-arteritic anterior ischemic optic neuropathy (NAION) should avoid sildenafil due to potential risk of vision loss.
