Vardenafil Tablets 20 mg: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing - Comprehensive Guide
What are Vardenafil Tablets 20 mg Used For?
Vardenafil is primarily prescribed to treat erectile dysfunction, a condition characterized by difficulty in obtaining or maintaining an erection sufficient for satisfactory sexual performance. This medication is effective in enhancing erectile response when sexual stimulation occurs. It is crucial to consult your healthcare provider to determine if vardenafil is suitable for your particular medical condition, especially considering any personal or family health history.
How Does Vardenafil Work?
Vardenafil functions by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which facilitates the relaxation of blood vessels in the penis. This enzyme inhibition results in increased blood flow to the penis during sexual stimulation, thereby leading to an erection. Vardenafil's action allows for a more natural erectile response, enhancing sexual performance and satisfaction.

Allergies: Individuals with known allergies to vardenafil or its components should not use this medication. Always inform your healthcare provider of any previous allergic reactions.
Drug Interactions: It is essential to inform your healthcare provider about all medications you are currently taking, including over-the-counter drugs and supplements. Vardenafil can interact with nitrate medications (used for angina) and other PDE5 inhibitors, leading to potentially dangerous effects.
Important Considerations Before Taking Vardenafil
Vardenafil is prescribed on an as-needed basis, typically taken about one hour before sexual activity. It is crucial to adhere to the recommended dose and not exceed it, as doing so can cause unwanted side effects or complications.
Additionally, vardenafil does not provide protection against sexually transmitted infections, including HIV. Consult your healthcare provider regarding protective measures to ensure safe sexual practices.
Drug Interactions
Food and Drink Interactions
Avoid consuming grapefruit or grapefruit juice while taking vardenafil, as this may increase the risk of side effects by raising vardenafil levels in the bloodstream. It is also advisable to discuss dietary habits with your healthcare provider.
Drug Interactions
Vardenafil may interact with several medications, including but not limited to:
- Nitrates (e.g., nitroglycerin, commonly used for chest pain)
- Alpha-blockers (medications that lower blood pressure)

- Other erectile dysfunction medications, which could enhance effects and side effects
Always consult your healthcare provider regarding potential interactions before starting vardenafil to ensure safe and effective treatment.
Overdose and Missed Dose
What to Do in Case of Overdose?
If you suspect an overdose, seek immediate medical attention. Signs may include severe dizziness, fainting, or prolonged erections that can pose serious health risks.
What to Do If You Miss a Dose?
Vardenafil is taken as needed and not on a schedule. If you miss a dose, take it when you remember, but do not double the dose to catch up, as this could increase the risk of side effects.
