Sildenafil 100mg, often recognized by the brand name Viagra, is predominantly utilized to address erectile dysfunction (ED) in men. Erectile dysfunction signifies the inability to achieve or sustain an erection that is adequate for sexual activity. Additionally, sildenafil (also marketed as Liqrev or Revatio) is prescribed to improve exercise capacity in adults and children aged over one year who suffer from pulmonary arterial hypertension (PAH), a medical condition marked by elevated blood pressure in the blood vessels leading to the lungs. This medication falls under the category of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, which play a crucial role in facilitating bodily functions.
The mode of action of sildenafil revolves around enhancing blood flow to the penis during sexual arousal, thereby aiding in the facilitation of an erection. For individuals suffering from PAH, sildenafil functions by relaxing the pulmonary blood vessels, thereby facilitating blood flow and lessening the burden on the heart, ultimately leading to an improved capacity for physical activity.
It is vital to emphasize that sildenafil does not serve as a cure for erectile dysfunction nor does it stimulate sexual desire. Furthermore, it does not offer any protection against sexually transmitted infections or prevent unintended pregnancies.
Sildenafil is accessible in both tablet form and as a liquid suspension intended for oral administration.
When taking sildenafil for erectile dysfunction, it is imperative to adhere to your physician's directives closely. Generally, you should ingest sildenafil as needed in proximity to sexual activity. The advised time frame for taking sildenafil is approximately one hour prior to engaging in sexual intercourse; however, it can be taken at any point between 30 minutes and 4 hours prior to the sexual encounter. Typically, it should not be consumed more than once within a 24-hour period. Depending upon your overall health and any other medications you may be taking, your doctor may suggest a variant dosing regimen.
For the treatment of PAH, sildenafil is normally taken three times daily, regardless of food intake. It is recommended to take it at consistent times each day to maintain uniform drug levels in your body.
Ensure you carefully follow the directions on your medication label. Should you have any inquiries regarding how to properly use sildenafil, it is advisable to consult your healthcare provider or pharmacist for clarity.
Sildenafil may occasionally be prescribed for varying medical conditions. If you have questions regarding these alternative uses, please consult with your healthcare provider for further information.
Prior to using sildenafil,
- Notify your doctor and pharmacist about any known allergies to sildenafil or other medications you may have.
- Certain medications are contraindicated when used in conjunction with sildenafil. Discuss your current medications with your healthcare provider if you are taking nitrates (prescribed for chest pain) such as isosorbide dinitrate (Isordil), isosorbide mononitrate (Monoket), or nitroglycerin (Nitro-Dur, Nitrostat).
- Inform your healthcare provider if you are using recreational drugs containing nitrates (often referred to as 'poppers'). Your physician may advise against the use of sildenafil if these substances are part of your lifestyle.
- Maintain communication with your physician regarding any other prescription or over-the-counter medications, vitamins, or dietary supplements in your possession, as these may interact adversely with sildenafil.
- Be aware that sildenafil is available under the brand names Liqrev, Revatio, and Viagra. You should only be treated with one of these products concurrently.
- Advise your healthcare provider of any history of heart disease, vision issues, or other significant health concerns that may influence your use of sildenafil.
- If you are a female using sildenafil for PAH, be sure to inform your healthcare provider if you are pregnant, plan to become pregnant, or are breastfeeding.
- Report any instances of painful or extended erections lasting longer than four hours, as this necessitates immediate medical intervention.

Store sildenafil in its original container, tightly sealed, and out of reach of children. Maintain tablets at room temperature while protecting them from excessive heat and moisture. If you possess a liquid suspension, store it at room temperature or refrigerated, but avoid freezing. Dispose of any unused suspension after 60 days to ensure safety.
Always keep medications out of the reach of children and ensure they cannot access them. Safely dispose of any unneeded medications through a community drug take-back program. For safe disposal methods, consult your pharmacist.
