How Viagra Tablets Work
Viagra tablets contain sildenafil citrate, which belongs to a group of medicines called PDE5 inhibitors. When sexually aroused, sildenafil helps increase blood flow to the penis by relaxing blood vessels. The medication does not cause automatic erections - sexual stimulation is still required for effectiveness.
Viagra Dosages Available
Viagra is available in three tablet strengths: 25mg, 50mg, and 100mg. Most men start with the 50mg dose, which may be adjusted to 25mg or 100mg depending on effectiveness and side effects. Only one tablet should be taken within 24 hours, approximately 30-60 minutes before planned sexual activity.
Common Side Effects
Like all medicines, Viagra may cause side effects. Common reactions include headache, facial flushing, indigestion, and nasal congestion. These effects are usually mild and temporary. Serious side effects are rare but may include sudden vision or hearing loss, chest pain, or prolonged erections lasting over 4 hours requiring immediate medical attention.
Who Can Take Viagra
Viagra is suitable for adult men diagnosed with erectile dysfunction following clinical assessment. The medication is not appropriate for women, men under 18, or those taking nitrate medications for heart conditions. A thorough medical consultation evaluates cardiovascular health, current medications, and medical history before prescribing.
Branded vs Generic Options
EverydayMeds offers both branded Viagra (manufactured by Pfizer) and generic sildenafil containing the same active ingredient. Generic sildenafil provides equivalent effectiveness at a lower cost. Patients can select their preferred option during the checkout process following successful clinical assessment.
Important Safety Information
Never combine Viagra with nitrate medications such as GTN sprays or isosorbide tablets, as this may cause dangerous drops in blood pressure. Alcohol may reduce effectiveness and increase side effects. Grapefruit juice should be avoided as it may affect how the body processes sildenafil.
