Drug Interactions With Cardura
As with any medication, drug interactions with Cardura are possible. Taking it with other medications, such as cimetidine, vardenafil, or sildenafil, can increase the level of Cardura in your blood, potentially increasing your risk of side effects, such as dangerously low blood pressure. If drug interactions with Cardura are a concern, your healthcare provider may adjust your dosages or monitor you more closely.

- Avanafil (Stendra™)
- Cimetidine (Tagamet®)
- Sildenafil (Viagra®, Revatio®)
- Tadalafil (Cialis®, Adcirca®)
- Vardenafil (Levitra®, Staxyn™).
