Schedule a doctor’s appointment if you experience chest pain, irregular heartbeat, or prolonged erection (lasting more than four hours). These are serious side effects requiring immediate medical attention.
Side Effects Requiring Medical Attention
Contact your physician if you notice vision changes, such as sudden vision loss or blue tint. Hearing loss or ringing in the ears also warrant immediate medical advice. Seek help if you experience dizziness, fainting, or a sudden drop in blood pressure.
Drug Interactions and Pre-existing Conditions
Always inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements. This includes nitrates, alpha-blockers, and other heart medications. If you have heart disease, high blood pressure, kidney disease, liver disease, or a history of stroke, discuss Cialis use with your doctor before starting treatment. Your doctor will assess your overall health and determine the appropriate dosage or if Cialis is right for you.
Lack of Effectiveness or Unexpected Reactions
If Cialis isn’t working as expected, or you experience unexpected side effects not listed above, contact your physician for guidance. They can adjust your dosage or recommend alternative treatment options.
