Pfizer’s Viagra, initially marketed as Sildenafil Citrate, contains the active ingredient sildenafil. This ingredient belongs to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors.
Sildenafil works by relaxing the blood vessels in the penis, increasing blood flow and facilitating an erection. The dosage varies depending on individual needs and physician recommendations, typically ranging from 25mg to 100mg. Always consult a doctor before using Viagra or any medication.
The medication comes in tablet form, and its effects typically last for four to five hours. Individual responses may differ, and factors like age, health, and diet can influence the duration and intensity of effects. You should inform your doctor about any existing health conditions before taking Viagra, particularly heart problems or blood pressure issues.
Generic versions of sildenafil are available, offering a more affordable alternative to the branded Pfizer product. However, ensure the generic drug comes from a reputable source to guarantee quality and safety.
Remember that Viagra is a prescription medication. Self-medicating can be dangerous. Always follow your doctor’s instructions and seek medical advice if you experience any adverse effects.
