Product Description
Sildenafil Tablet 50mg is a medication primarily known by its brand name, Viagra, used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping a man achieve and maintain an erection during sexual stimulation.
Understanding Sildenafil's Mechanism:
Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by blocking the action of a specific enzyme, PDE5, which is involved in the breakdown of a chemical messenger called cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing the muscles in the penis, allowing blood to flow in and cause an erection. By inhibiting PDE5, sildenafil allows cGMP levels to remain elevated, leading to muscle relaxation and increased blood flow.
How to Use Sildenafil:
- Take Sildenafil by mouth as directed by your doctor, typically as needed.
- Take the tablet at least 30 minutes, but no more than 4 hours, before sexual activity. The most effective time is generally one hour before.
- Do not take more than once daily.
- A high-fat meal may delay how quickly the drug starts working.
- The dosage is based on your medical condition, response to treatment, and other medications you may be taking.
Important Precautions and Potential Side Effects:
- Pregnancy: Sildenafil should only be used during pregnancy when clearly necessary. It can harm a developing fetus.
- Breastfeeding: Sildenafil passes into breast milk in small amounts. Consult your doctor before breastfeeding.
- Heart Problems: Sexual activity can put extra strain on your heart, especially if you have heart problems. If you experience any serious side effects during sex, such as severe dizziness, fainting, chest pain, or nausea, stop and seek immediate medical help.
- Vision Problems: Rarely, sudden decreased vision, including permanent blindness, in one or both eyes (NAION) may occur. If this happens, stop taking sildenafil and get medical help right away.
- Hearing Loss: Rarely, a sudden decrease or loss of hearing, sometimes with ringing in the ears and dizziness, may occur. Stop taking sildenafil and get medical help right away if this happens.
- Priapism: In rare cases, a painful or prolonged erection lasting 4 or more hours may occur. Stop using the drug and get medical help immediately to prevent permanent problems.
- Drug Interactions: Sildenafil can interact with many other medications, including nitrates (used for chest pain) and some antifungal and antibiotic medications. Inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements.
- Grapefruit: Avoid eating grapefruit or drinking grapefruit juice while taking sildenafil, as it can increase the risk of side effects.
