Cenforce Soft (sildenafil citrate soft tablets) should be avoided or used only under strict medical supervision in several medical conditions because it can significantly affect blood pressure and cardiovascular function. The most important contraindication is the use of nitrate medications (such as nitroglycerin or isosorbide drugs for chest pain). Combining these with sildenafil can cause a dangerous, potentially life-threatening drop in blood pressure. People with serious heart conditions should also avoid it unless a doctor specifically approves use. This includes recent heart attack (myocardial infarction), recent stroke, unstable angina, or severe heart failure, especially if ***** activity itself is risky for the heart. Severe low blood pressure (hypotension) or uncontrolled high blood pressure are also concerns, as sildenafil can further destabilize circulation. Similarly, severe liver impairment or advanced kidney disease may increase drug levels in the body and raise the risk of side effects. It should not be used in individuals with a history of vision problems related to optic nerve damage, such as non-arteritic anterior ischemic optic neuropathy (NAION), or rare inherited eye conditions like retinitis pigmentosa, due to potential risk of worsening vision issues. Another important contraindication is the use of riociguat (a medication for pulmonary hypertension), as the combination can also lead to severe hypotension.
