What is Viagra?
Viagra is the brand name of the medication sildenafil, which is widely used to treat erectile dysfunction and impotence in men. It works by increasing the blood flow to the penis, facilitating the ability to achieve and maintain an erection. However, it is important to note that sildenafil does not enhance sexual desire nor does it induce an erection without sexual stimulation. Additionally, this medication does not act as a preventative measure against sexually transmitted diseases; it is still vital to practice safe sex.
How does Viagra work?
Viagra functions by relaxing the muscles within the walls of blood vessels, which in turn allows for increased blood flow to targeted regions of the body, particularly enhancing the natural blood flow to the penis. When taken in conjunction with sexual stimulation, this process effectively aids a man in obtaining and sustaining an erection.
How long does Viagra last?
Viagra is most effective when taken about 30 to 60 minutes prior to engaging in sexual activity but may be administered up to four hours beforehand. To maximize its effectiveness, it is generally recommended to take the medication approximately one hour before sexual engagement. It is crucial to adhere to the guideline of not exceeding one tablet of sildenafil within a 24-hour period.
How much does Viagra cost?
The cost of your medication can vary based on the strength and quantity you opt to purchase. Many individuals in America frequently inquire as to why Viagra is so expensive; however, purchasing Viagra online can yield savings of up to 90% compared to traditional pharmacy prices. Additional savings can be realized by opting for the generic version, sildenafil, especially if you buy a 90-day supply. You won’t need a Viagra coupon to benefit from our outstanding pricing.
Always ensure to read the patient information and instructions thoroughly before using this medication.
- Take Viagra tablets orally.
- Sildenafil citrate is best utilized within 30 to 60 minutes after ingestion but can be taken up to four hours prior to sexual activity for convenience.
- Consuming a high-fat meal may delay the onset of Viagra’s effectiveness.
- Your prescribed Viagra dosage will depend on various factors including your individual medical condition, other medications you may be taking, and your overall response to treatment.
- Use of more than one tablet of Viagra in a single day is not recommended under any circumstances.
It is essential to inform your doctor and pharmacist of the following:
- If you have any known drug allergies.
- What other prescription and non-prescription medications you are currently taking.
- Your medical history, particularly regarding heart conditions such as heart disease, heart attacks, strokes, congestive heart failure, heart rhythm disorders or coronary artery disease. Also include any liver disease, kidney disease, high or low blood pressure, or blood disorders like leukemia, multiple myeloma, hemophilia, or sickle cell anemia, as well as conditions like stomach ulcers or retinitis pigmentosa.
- If you've been diagnosed with any physical deformity of the penis, such as Peyronie’s disease.
- If you have previously been advised against sexual intercourse for health concerns.
- If you are currently using any nitrate drugs for managing chest pain or heart issues. This includes recreational substances like poppers or amyl nitrate, and prescription medications like nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
- If you are using marijuana or cannabis products.
Additionally, please be aware that:
- This medication is not advisable for anyone under the age of 18 without proper medical consultation and supervision.
- Viagra may cause dizziness or alter your vision; thus, you should refrain from driving or operating machinery until you are sure you can do so safely.
- Combining Viagra with alcohol or marijuana may amplify dizziness or lead to other adverse side effects. It is advisable to limit alcohol consumption during usage of Viagra. Notify your doctor if you also consume marijuana.
- For women, sildenafil should only be taken when absolutely necessary during pregnancy or breastfeeding, as high blood pressure in the lungs could pose risks to both the expectant mother and the unborn child.
Common side effects of Viagra may include, but are not limited to:
- Flushing, which can manifest as warmth, redness, or a tingling sensation.
- Headaches, dizziness, muscle or back pain, or gastrointestinal discomfort.
- Blurred vision or variations in color vision.
- Runny or congested nasal passages along with possible nosebleeds.

- Changes in vision or sudden loss of vision.
- A painful erection or one that lasts longer than 4 hours, which necessitates immediate medical attention.
