Quick Facts

What It Is and How It Works
Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by inhibiting the PDE5 enzyme, leading to increased levels of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis. This biochemical cascade results in the relaxation of these muscles and increased blood flow, which are necessary for an erection to occur in response to sexual stimulation.
Indications / Uses
The primary approved use of sildenafil is for the treatment of erectile dysfunction (ED), a condition characterized by the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. While off-label uses may exist, they should only be considered under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Sildenafil is commonly available in oral tablet form, with doses typically ranging from 25 mg to 100 mg. The 200 mg dosage form may be considered in specific cases but is not standard practice due to increased risk of side effects. Dosing depends on several factors, including the patient\’s age, underlying health conditions, and the presence of other medications. It\’s essential that dosing adjustments are guided by a healthcare professional.
How to Take It Correctly Step-by-Step
Sildenafil should be taken approximately 30 minutes to 4 hours before sexual activity. It can be taken with or without food, though high-fat meals might delay its onset of action. It\’s important to adhere to the prescribed dosage and never take more than recommended by a healthcare provider. If a dose is missed, it should be taken when remembered unless it\’s almost time for the next dose. Avoid double dosing.
Side Effects Common to Serious
Common Side Effects
These can include headaches, flushing, nasal congestion, dizziness, and indigestion. Most are mild and transient.
Less Common Side Effects

Serious or Rare Side Effects
Seek medical attention for symptoms such as sudden vision or hearing loss, chest pain, or an erection lasting more than 4 hours.
Contraindications & Precautions
Individuals with a known allergy to sildenafil or similar medications should not use it. It should be avoided in patients taking nitrates or with significant cardiovascular conditions. Special caution is advised for those with liver or kidney impairment, retinitis pigmentosa, or a history of stroke or heart attack.
Drug, Food, and Supplement Interactions
Sildenafil can interact with nitrates (leading to potentially life-threatening drops in blood pressure), alpha-blockers, certain antifungals, and HIV protease inhibitors. Alcohol consumption can exacerbate possible side effects like dizziness. Patients should discuss their complete medication list, including prescription drugs, OTC medications, and supplements, with their healthcare provider.
