How Does Generic Viagra Work?

Generic Viagra functions by inhibiting the activity of a particular enzyme called phosphodiesterase type 5 (PDE5) found in the corpus cavernosum of the penis. PDE5 controls blood flow to the penile area by breaking down cyclic guanosine monophosphate (cGMP) following ejaculation. However, excessive PDE5 levels can hinder the development of an erection.

Generic Viagra ensures that PDE5 levels stay low enough for a man to achieve a stable and long-lasting erection. By blocking PDE5, sildenafil, the active ingredient in Generic Viagra, enables the release of nitric oxide, which activates cGMP and promotes an erection.

Sildenafil Dosages: from 25mg to 200mg

The range of dosage strengths for generic Viagra is broader than that of the branded drug, varying from 25mg to 200mg of sildenafil per tablet. Your doctor will consider your medical history, the severity of your condition, and other relevant factors to determine the most appropriate dosage that will yield optimal results without jeopardizing your health.

  • 25mg is the lowest starting dose given to new patients to evaluate their response to the treatment and assess their sensitivity to sildenafil. It may be effective and sufficient for patients with mild erectile dysfunction.
  • 50mg is the most commonly prescribed dosage of the drug that is well-tolerated and effective for the majority of patients with mild-to-moderate ED symptoms.
  • 100mg is the dosage usually given to patients with moderate to severe ED symptoms. It is often prescribed to men for whom lower-dose Viagra did not work well enough.
  • 150mg has an enhanced formula designed to help men with severe and very severe forms of erectile dysfunction. This dosage of sildenafil is not considered safe and should only be taken when your doctor believes it is the best available treatment option for you.
  • 200mg is the highest possible dosage of this medication. The unsupervised use or self-administration of 200 milligrams of sildenafil is strongly discouraged, as it may pose life-threatening risks. Men who purchase generic Viagra 200mg often find it safer to divide the pill into two or four parts. It should not be used if you are over 55 years old or have any coexisting heart or health issues.

Is Long-Term or Daily Use Safe?

It is essential to recognize that generic Viagra is designed for temporary relief of ED symptoms and does not provide a permanent solution for improving erectile function. Nevertheless, daily use of the medication is permitted and safe, provided that the prescribed dosing regimen is strictly adhered to under the guidance of a medical professional.

Is It Possible to Overdose?

By following your doctor’s instructions on the appropriate use of generic Viagra, the likelihood of experiencing an overdose is rare and unlikely. However, men who exceed the recommended dosage may face unpleasant and potentially dangerous effects. These symptoms may include severe headaches, intense nausea, significant hearing or vision impairment, acute chest pain, highly irregular heartbeats, or difficulty breathing. Adhering to the prescribed guidelines is essential to prevent such occurrences

Things You Should Know Before Your Take Your Very First Pill

  1. Adhere to your doctor’s instructions when taking generic Viagra. Do not alter the dose or frequency of administration as it can lead to serious and potentially life-threatening side effects.
  2. Avoid having a heavy meal prior to taking generic Viagra, as it may impede the drug’s absorption and decrease its efficacy.
  3. Do not consume alcohol while using Viagra, as it not only reduces the drug’s effectiveness but also increases the likelihood and severity of side effects.
  4. Avoid combining Viagra with grapefruit or grapefruit juice, as it can result in a rapid increase in the levels of sildenafil in your blood. Although this may result in a stronger erection, the aftermath could be unpleasant and problematic.

Is a Prescription Required to Purchase Generic Viagra?

The legality of purchasing generic Viagra varies depending on the country in question. In the US, Canada, and most European nations, both branded and generic Viagra can only be legally obtained with a valid prescription from a licensed doctor. This ensures that the patient has received a proper diagnosis before taking the drug.

However, many unscrupulous online pharmacies based abroad offer to sell generic Viagra over-the-counter. This is highly dangerous, as these medications may be of unknown origin and their suitability for the customer has not been medically verified.

Regardless of whether you are purchasing generic Viagra from a local pharmacy or online, it is important to ensure that the source is trustworthy and compliant with the law. Look for a reputable store that prioritizes your safety by requiring a legitimate prescription from a doctor.

In addition to sildenafil citrate, a Viagra tablet also includes inactive ingredients and fillers that serve to stabilize the medication, enhance its flavor, and prevent degradation over time.

Inform your physician about any medicinal and non-medicinal drugs, herbal additives, and vitamins you are taking so that he can accurately assess the suitability of sildenafil for you.

Side Effects

The most frequent side effects associated with generic Viagra include nasal congestion, headaches, mild vision changes, ringing in the ears, dizziness, nausea, vomiting, and occasional back pain. These side effects are typically not dangerous and will typically resolve on their own. However, in some instances, your doctor may recommend symptomatic treatment.

  • priapism;
  • sudden loss of hearing or vision;
  • difficulty breathing;
  • acute pain in the chest;
