SILDENAFIL CITRATE (Generic for REVATIO)

Sildenafil Citrate 100mg, Oral tablet

Grapefruit juice

· Severity: Moderate

· Notes for Consumers: Grapefruit juice and grapefruit-containing foods may increase the side effects of Sildenafil. Do not significantly alter grapefruit juice intake while taking this drug, or avoid grapefruit juice if possible. When taking Sildenafil, contact your prescriber immediately if you experience chest pain, dizziness, fainting or falling spells, palpitations, shortness of breath, or a change in your usual heart beat (fast, slow, or irregular heart beat).

· Notes for Professionals: Sildenafil is metabolized via the cytochrome CYP 3A4 isozyme. Grapefruit juice contains a compound that inhibits CYP3A4 in enterocytes in the GI tract. Sildenafil levels may increase; it is possible that sildenafil-induced side effects could also be increased in some individuals. One study has confirmed a potential interaction; sildenafil's AUC increased 23 percent with coadministration of grapefruit juice.
