Sesame and Sildenafil

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Sildenafil

Sildenafil falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Sesame interacts with.

Theoretically, sesame might increase the levels and clinical effects of CYP2C9 substrates.
In vitro, sesame inhibits CYP2C9. However, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for sesame and sildenafil. Your liver uses an enzyme called CYP2C9 to help clear sildenafil out. In test-tube studies, compounds in sesame (like the lignans) appear to slow that enzyme down a bit. Sildenafil is active as-is, not a prodrug, so if it clears more slowly it could hang around at slightly higher levels. In theory, that might nudge up its effects and side effects, things like headache, flushing, a stuffy nose, dizziness, or a bigger drop in blood pressure.

The important part: this is only seen in lab studies, never reported in real people, and everyday sesame in food is very unlikely to matter. Concentrated sesame supplements are less studied, so if you use those, just mention it to your pharmacist or doctor.

About Sesame

What is Sesame?

  • Heart and cholesterol health
  • Blood pressure support
  • Source of healthy fats and minerals
  • Skin and hair care (topical oil)
  • Antioxidant support
  • Cooking and nutrition

Sesame is a nutritious seed and oil widely used in cooking and traditional medicine, and it provides healthy fats, fiber, and antioxidant compounds called lignans. Some early research suggests sesame may modestly help with cholesterol and blood pressure, but the evidence is limited. Sesame is also a common, sometimes serious, food allergen, so people with seed allergies should be careful.

About Sildenafil

What Is Sildenafil Used For?

Brand name: Revatio

Sildenafil treats two distinct conditions depending on the product. Viagra (tablet) and Vybrique (dissolving oral film) are approved for erectile dysfunction (ED) — difficulty getting or keeping an erection. Generic sildenafil tablets and oral film are also approved for ED.

Revatio and several generic sildenafil products (tablets, oral suspension, and injection) are used for pulmonary arterial hypertension (PAH) — high blood pressure in the arteries of the lungs — in adults to improve exercise ability and slow the disease from getting worse. Revatio oral suspension and injection are also approved for PAH in children ages 1 to 17.
