Viagra: Comprehensive Guide for Erectile Dysfunction Treatment
What is Viagra (Sildenafil Citrate)?
Viagra, containing the active ingredient Sildenafil Citrate, is a medication primarily used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis during sexual stimulation, leading to improved erectile function. Beyond ED, Sildenafil Citrate is also prescribed for pulmonary arterial hypertension (PAH), improving exercise capacity and reducing pulmonary artery pressure.
How Viagra Works: The Science Behind the Erection
Sildenafil Citrate enhances the effects of nitric oxide, a natural chemical released in response to sexual stimulation. Nitric oxide triggers the relaxation of smooth muscles in the penis, allowing more blood to flow in. Viagra inhibits an enzyme called phosphodiesterase type 5 (PDE5), which breaks down nitric oxide. By inhibiting PDE5, Viagra helps maintain higher levels of nitric oxide, promoting increased blood flow and facilitating an erection when sexually aroused. This mechanism makes Viagra an effective solution for men experiencing difficulty achieving or maintaining an erection. Buy Viagra online for a discreet and convenient solution.
Uses of Viagra (Sildenafil Citrate)
- Erectile Dysfunction (ED): The primary use of Viagra is to treat ED, also known as impotence, in men. It helps men achieve and maintain an erection sufficient for satisfactory sexual intercourse.
- Pulmonary Arterial Hypertension (PAH): Viagra is also used to treat PAH, a condition where blood pressure in the arteries leading to the lungs is too high. It helps relax the blood vessels in the lungs, allowing blood to flow more easily and reducing the workload on the heart.
Viagra Dosage and Administration
The typical starting dose of Viagra for ED is 50 mg, taken orally approximately 30 minutes to 1 hour before sexual activity. Depending on individual response and tolerability, the dose may be increased to 100 mg or decreased to 25 mg. Do not take Viagra more than once per day. For PAH, the dosage and frequency may differ and will be determined by your doctor. Always follow your doctor's instructions precisely. Consider purchasing Viagra online for a hassle-free experience.
Important Considerations Regarding Viagra Dosage:
- Food Interactions: A high-fat meal can delay the absorption of Sildenafil Citrate, potentially delaying the onset of its effects. Consider taking Viagra on an empty stomach or after a light meal.
- Grapefruit Juice: Avoid consuming grapefruit or grapefruit juice while taking Viagra, as it can increase the concentration of Sildenafil Citrate in the bloodstream and potentially increase the risk of side effects.
- Alcohol: Excessive alcohol consumption can worsen erectile dysfunction and may also increase the risk of side effects associated with Viagra.
Viagra Precautions: Is Viagra Right for You?
Before taking Viagra, discuss your medical history with your doctor or pharmacist, especially if you have any of the following conditions:
- Heart problems (e.g., irregular heartbeat, chest pain, heart failure)
- Kidney or liver disease
- High or low blood pressure
- History of stroke or heart attack
- Eye problems (e.g., retinitis pigmentosa, NAION)
- Bleeding disorders
- Peptic ulcers
- Deformity of the penis (e.g., Peyronie's disease)
- Allergies to Sildenafil Citrate or any other medications
Special Populations and Viagra Use:
- Elderly Patients: Elderly individuals may be more susceptible to the side effects of Viagra and may require a lower starting dose.
- Children: Viagra is not intended for use in children.
- Women: Viagra is not typically prescribed for women.
Viagra Contraindications: When NOT to Take Viagra
Viagra is contraindicated in individuals with the following conditions:
- Taking nitrate medications for chest pain or heart problems (e.g., nitroglycerin, isosorbide dinitrate)
- Using other medications for erectile dysfunction
- Known hypersensitivity or allergy to Sildenafil Citrate or any other component of the tablet
- Severe heart or liver problems
- Recent stroke or heart attack
- Low blood pressure
- Certain eye conditions (e.g., retinitis pigmentosa)

- Headache
- Flushing
- Heartburn
- Stomach upset
- Nasal congestion

- Sudden hearing loss
- Chest pain
- Irregular heartbeat
- Shortness of breath
- Seizures
- Prolonged erection lasting more than 4 hours (priapism)
Viagra Drug Interactions: What to Avoid
Viagra can interact with several medications, potentially leading to adverse effects. Avoid using Viagra with the following:
- Nitrates: Nitrates, such as nitroglycerin, used to treat angina (chest pain). The combination can cause a dangerous drop in blood pressure.
- Alpha-blockers: Medications used to treat high blood pressure or prostate problems (e.g., terazosin, doxazosin). The combination can cause low blood pressure.
- Other ED medications: Using Viagra with other drugs for erectile dysfunction is not recommended.
- Recreational drugs ("poppers"): These contain amyl or butyl nitrite and can cause a dangerous drop in blood pressure.
- Certain antifungal medications: Ketoconazole and itraconazole can increase the levels of sildenafil in the blood.
- Certain antibiotics: Erythromycin and clarithromycin can also increase sildenafil levels.
- HIV protease inhibitors: Ritonavir and other protease inhibitors used to treat HIV can significantly increase sildenafil levels, requiring a dose adjustment.
Always inform your doctor about all medications, supplements, and herbal products you are taking before starting Viagra treatment. Find affordable Viagra prices and purchase your medication online.
What to Do in Case of a Missed Viagra Dose
Viagra is typically taken as needed, about 30 minutes to 1 hour before sexual activity. If you miss a dose, simply take it when you remember, as long as it is not too close to your next scheduled dose. Do not take a double dose to make up for a missed one.
Viagra Overdose: What to Do in an Emergency
If you suspect you have taken too much Viagra, seek immediate medical attention. Overdose symptoms may include chest pain, nausea, irregular heartbeat, lightheadedness, and fainting.
How to Store Viagra Properly
Store Viagra at room temperature (68-77°F or 20-25°C) away from light and moisture. Keep the medication out of the reach of children and pets. Do not store Viagra in the bathroom.
