Who is this meant for

Sildenafil is intended for adult males who have difficulty achieving or maintaining an erection sufficient for sexual activity when sexual stimulation is present. It is not an aphrodisiac and does not increase sexual desire.

If ED appears suddenly or worsens, a medical review is recommended to exclude underlying causes such as cardiovascular disease, hormonal problems, or neurological conditions. Women and children are not appropriate candidates for sildenafil for ED; other licensed signals indicating exist for different populations and require specialist oversight.

For regulatory and prescribing information, see the section on notes about legality and regulation.

The Mechanism Behind It

Sexual arousal stimulates release of nitric oxide in penile tissue. Nitric oxide increases levels of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscle in the corpus cavernosum and allows blood inflow to produce an erection. PDE5 breaks down cGMP; by inhibiting PDE5, sildenafil prolongs cGMP activity and assists erection when sexual stimulation occurs.

Sildenafil will not trigger an erection in the absence of sexual stimulation. For information about personal the mutual influence during contacts build trust and rapport. that affect how fast or how strongly it acts, consult interaction between prescription drugs and food.

• Meals: a high fat meal can delay absorption and slow onset; an empty stomach usually produces faster effect.
• Grapefruit: avoid grapefruit and grapefruit juice close to dosing because they can raise sildenafil levels.

People with impaired liver or kidney function, those taking certain interacting medicines, and older adults may require a lower starting dose. Always follow the directions given by your healthcare professional.

• Strong CYP3A4 inhibitors (for example ketoconazole, itraconazole, ritonavir, cobicistat, clarithromycin): increase sildenafil exposure and often necessitate dose reduction or avoidance.
• CYP3A4 inducers (for example rifampicin, carbamazepine, phenytoin): may reduce sildenafil concentrations and effectiveness.
• Grapefruit juice: can elevate blood levels of sildenafil; avoid near dosing.
