- Severe liver disease Severe kidney disease Blood cell disorders like sickle cell anemia Retinitis pigmentosa (an inherited eye disease) A stomach ulcer A history of priapism (a prolonged and painful erection) Known hypersensitivity or allergy to tadalafil (the active ingredient in Cialis)
Medications to Discuss with Your Doctor
Cialis can interact negatively with several medications. Before taking Cialis, inform your doctor of all medications you are currently using, including:
- Nitrates (often used for chest pain) Alpha-blockers (used to treat high blood pressure and enlarged prostate) Certain antifungals HIV protease inhibitors Other ED medications
Other Important Considerations
Cialis is not suitable for everyone. Individuals under 18 years old should not use this medication. Furthermore, people with certain heart conditions or taking specific medications might experience a dangerous drop in blood pressure. Always follow your doctor’s instructions regarding dosage and usage.
Openly discuss all health concerns with your physician before starting any new medication. Never exceed the recommended dosage. Seek immediate medical attention if you experience any adverse effects, such as prolonged erection (longer than 4 hours).
