Sildenafil Citrate Tablets: A Comprehensive Guide
Always consult your doctor before starting sildenafil citrate. This medication isn’t suitable for everyone.
Sildenafil citrate tablets, commonly known as Viagra, primarily treat erectile dysfunction (ED) by increasing blood flow to the penis. Dosage typically ranges from 25mg to 100mg, taken orally as needed, approximately one hour before sexual activity. The precise dose depends on individual needs and your doctor’s assessment.
Common side effects include headache, flushing, nasal congestion, and visual disturbances. Serious side effects are rare but include sudden vision loss or hearing loss. Seek immediate medical attention if you experience these.
Interactions with other medications exist. Specifically, combining sildenafil with nitrates can cause a dangerous drop in blood pressure. Inform your doctor about all medications, including over-the-counter drugs and supplements, you currently take.
Proper storage is vital. Keep sildenafil tablets in a cool, dry place, away from direct sunlight and moisture.
Remember, this information is for general knowledge only and does not replace professional medical advice. A thorough medical examination and discussion with your doctor are necessary before using sildenafil citrate or any medication for ED.
Understanding Sildenafil Citrate’s Mechanism of Action
Sildenafil citrate works by inhibiting a specific enzyme called phosphodiesterase-5 (PDE5).
PDE5 Inhibition and cGMP Levels
PDE5 normally breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule for smooth muscle relaxation in the penis. By blocking PDE5, sildenafil increases cGMP levels. Higher cGMP levels lead to relaxation of the smooth muscles in the blood vessel walls of the penis.
Increased Blood Flow
This relaxation allows for increased blood flow into the corpora cavernosa, the erectile tissues within the penis. This increased blood flow is the key to achieving and maintaining an erection.
Sexual Stimulation Required
- Sildenafil doesn’t directly cause an erection.
- Sexual stimulation is necessary to trigger the release of nitric oxide (NO).
- NO starts the process by increasing cGMP levels, which sildenafil then helps sustain.
Specific Actions
- Sildenafil selectively targets PDE5, minimizing effects on other PDE isoforms.
- This selectivity helps reduce potential side effects.
- The drug’s impact is localized primarily to the circulatory system of the penis.
Important Note
The duration of action varies, with effects generally lasting several hours. Consult your doctor regarding potential drug interactions and contraindications.
Other Relevant Factors
Dosage and Individual Response
Individual responses to sildenafil vary. Factors like age, overall health, and other medications can influence how effectively it works. Always follow your doctor’s prescribed dosage.
Common Uses and Efficacy of Sildenafil Citrate Tablets
Sildenafil citrate tablets, primarily known by the brand name Viagra, are FDA-approved for treating erectile dysfunction (ED) in men. This medication enhances the effects of nitric oxide, a naturally occurring substance in the body, resulting in improved blood flow to the penis, facilitating an erection. Many men experience significant improvement in their ability to achieve and maintain an erection sufficient for satisfactory sexual intercourse.
Dosage and Administration
The typical starting dose is 50mg, taken as needed, about one hour before sexual activity. Your doctor may adjust the dosage based on your response and individual needs, ranging from 25mg to 100mg. It’s crucial to follow your doctor’s instructions precisely. Sildenafil is not intended for daily use unless specifically prescribed by your doctor for pulmonary arterial hypertension (PAH).
Other Uses and Efficacy
Beyond ED, sildenafil is also used to treat pulmonary arterial hypertension (PAH), a condition affecting blood vessels in the lungs. In this context, it improves blood flow to the lungs, reducing strain on the heart. The efficacy in PAH treatment is established through numerous clinical trials demonstrating improved exercise capacity and quality of life for patients. However, it’s important to consult a physician for PAH treatment as dosage and administration differ significantly from its use for ED.
Potential Side Effects
Common side effects include headache, flushing, nasal congestion, and visual disturbances. More serious, albeit rare, side effects can include sudden vision loss or hearing loss. If you experience any unusual or concerning side effects, discontinue use and seek immediate medical attention. A thorough medical history and discussion with your doctor before starting treatment are essential to determine suitability and potential risks.
Potential Side Effects and Drug Interactions
Always inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements, before starting Sildenafil Citrate. This helps prevent potentially dangerous interactions.
Common Side Effects
Sildenafil can cause headaches, flushing, nasal congestion, and visual disturbances (such as blurred vision or changes in color perception). These usually are mild and temporary. More serious side effects, though rare, include chest pain, irregular heartbeat, and sudden vision loss. Seek immediate medical attention if you experience any of these.
Drug Interactions
Sildenafil interacts negatively with nitrates (used to treat angina) due to a risk of dangerously low blood pressure. It also interacts with certain blood pressure medications, alpha-blockers, and some antifungals. Using Sildenafil with these drugs may significantly increase the risk of side effects.
Specific Interactions and Considerations
| Medication Type | Interaction | Recommendation |
|---|---|---|
| Nitrates | Significant blood pressure drop | Avoid concurrent use. |
| Alpha-blockers | Increased risk of hypotension | Consult your doctor before combining. |
| Certain Antifungals (e.g., ketoconazole, itraconazole) | Increased Sildenafil levels | Dosage adjustment may be necessary. |
| Ritonavir (HIV protease inhibitor) | Increased Sildenafil levels | Doctor supervision is crucial. |
When to Contact Your Doctor
Contact your doctor immediately if you experience any concerning side effects, or if your symptoms persist or worsen. This includes any unusual changes in vision, hearing, or breathing.

Precautions and Considerations Before Taking Sildenafil Citrate
Consult your doctor before taking Sildenafil Citrate, especially if you have heart problems, low blood pressure, or have recently had a stroke or heart attack. This medication can interact negatively with certain heart medications. Be sure to disclose all medications you are currently taking, including herbal supplements.
Potential Side Effects
Sildenafil Citrate can cause headaches, flushing, nasal congestion, and visual disturbances. Rarely, more serious side effects can occur. If you experience prolonged or painful erections (priapism), seek immediate medical attention. This is a medical emergency. Report any significant side effects to your doctor.
Avoid grapefruit and grapefruit juice while taking Sildenafil Citrate. Grapefruit can increase the concentration of the medication in your bloodstream, potentially leading to adverse effects. Alcohol consumption should be moderated, as it can also interact with the drug and exacerbate side effects.
Sildenafil Citrate is not suitable for everyone. Pre-existing conditions like retinal problems or blood cell disorders require careful assessment before use. If you have any doubts or concerns, a thorough discussion with your physician is necessary before initiating treatment.
Medication Interactions
Certain medications, such as nitrates used to treat chest pain, interact dangerously with Sildenafil Citrate. Taking them together can cause a significant drop in blood pressure. Always inform your doctor about all medications you are using to prevent potentially hazardous interactions.
