Sildenafil, an oral medication known for its proven erectogenic effect, has shown statistically significant improvements in sexual function. For over 20 years, this drug has been safely used by men suffering from erectile dysfunction (ED) of various backgrounds. Sildenafil should only be taken when there is an inability to attain and maintain an erection. It has no effect on overall sexual desire.
Generic Viagra is a medication from the PDE5 inhibitors group (phosphodiesterase type 5) that eliminates symptoms associated with erectile dysfunction. Sildenafil was the first highly effective ED cure and currently includes four similar drugs. Although the market offers other alternatives, Viagra from Canadian pharmacies remains the most widely used ED medication, known for its proven reliability and safety.
More General Information
Sildenafil is a prescription medication that healthcare providers recommend exclusively to patients diagnosed with sexual dysfunction. The active ingredient in Viagra, sildenafil, is a powerful vasoactive agent. Due to its impact on blood pressure, there are several important contraindications and interactions associated with this drug. Below, we provide detailed information on these contraindications and interactions. However, it is crucial to consult with your doctor before starting treatment. Only your healthcare provider can determine whether the benefits of taking Viagra outweigh the risks in your specific situation and how to use the drug safely and effectively.
It is essential to purchase Sildenafil in the dosage prescribed by your doctor. Increasing the recommended dose can lead to serious side effects without improving health outcomes.
Combining Sildenafil with alcohol is strongly discouraged. Avoiding alcohol while using Sildenafil or any other PDE5 inhibitors is advisable. Both substances can cause hypotensive effects, and their combination can lead to a sudden drop in blood pressure, resulting in symptoms such as headache, nausea, blurred vision, and confusion. If you experience any of these symptoms, seek medical attention immediately. The same applies to the serious side effects listed below.
Available Dosages
The correct dosage can only be established in accordance with laboratory test results performed by your doctor and your medical history. The available Sildenafil doses are:
- 25mg
- 50mg
- 100mg
You can change your Sildenafil dose depending on the following:
- Patient’s response
- Health outcomes
- Patient’s tolerance
| Dose | Use |
| 25mg | As an initial dose In mild ED In patients with compromised kidneys function In patients with compromised liver function In 75+ patients |
| 50mg | As initial dose In moderate ED |
| 100mg | In non-responders to lower doses of sildenafil In severe ED after failure to respond to lower doses |
It’s important to remember that the initial dose of Sildenafil should be carefully adjusted by a physician, and increased gradually if necessary. Each dose should be tried at least eight times to confirm its effectiveness. Although Sildenafil’s efficacy depends on the dosage, taking more than the recommended amount won’t enhance its effectiveness without a medical evaluation. Always consult with your healthcare provider to ensure the best results.
Taking Method
Take a Sildenafil tablet about half an hour before you plan to engage in sexual activity. Ensure you drink plenty of water to enhance the pill’s effectiveness. Avoid crushing, chewing, or breaking the tablet, as this can reduce its efficacy.
When does Sildenafil start working? Sildenafil reaches its peak concentration in the blood approximately 60 minutes after ingestion, so plan accordingly. However, some users have reported noticing improved potency as soon as 20 minutes after taking the pill.
Side effects and Precautions
What side effects of Sildenafil can you expect? Most of Sildenafil’s side effects, such as facial flushing, headaches, dizziness, rhinitis, and sinusitis, are due to increased blood circulation. Other potential side effects include stomach discomfort, diarrhea, heartburn, and a temporary change in the perception of blue colors. These effects are usually mild and short-lived.
If you continue to experience these symptoms, they will likely diminish over time. However, if the side effects persist and are particularly bothersome, consult your healthcare provider. They may need to adjust your dosage to alleviate these issues. Always discuss any ongoing side effects with your doctor to ensure the safest and most effective use of Sildenafil.
In extremely rare cases (less than 1%), the following acute problems can occur:
- Swelling of the lips or face
- Increased heartbeat rate
- Pain in the chest or arm
- Difficulty breathing
- Synchope
- Painful or lasting (4+ hours) erection
Seek medical help immediately if you develop any of the above.
