About Actigra 100 mg

Actigra 100 mg is one of the most common medicines to treat Erectile Dysfunction (ED).

It is a condition in which a man can't get or keep a hard erection in the penile area that is good enough for sexual activity.

This happens when there is less blood flow because of a physical injury, a medical condition, or a psychological issue such as anxiety, depression, stress, etc.

Sildenafil is the active ingredient in Actigra 100 mg.

It widens the blood vessels to make your erection last longer, which increases blood flow to the penile area.

It makes sexual activity more satisfying and keeps you from losing your erection when you're most excited.

Uses of Actigra 100 mg

Actigra 100 mg helps in the treatment of ED or impotence in men.

The active ingredient of Actigra 100, Sildenafil, increases the blood flow to the penis to maintain an erection during sexual intercourse.

Through this process, a man can get or keep an erection easily.

How does Actigra 100 mg work

Sildenafil, the main ingredient of Actigra, inhibits the effects of Phosphodiesterase type 5 (PDE-5).

It helps relax the blood vessels in the penile region, which lets more blood flow to the penis when stimulated sexually.

Actigra can aid in achieving an erection, but you must be sexually stimulated for it to be effective.

This helps you get and keep a hard, erect penis that's good for sexual activity.

How to take medicine

You should follow the same dose of Actigra 100 that your doctor prescribes.

While taking this medicine, you should consider the following things:

  • Consume the same amount of dose as recommended by your doctor
  • Just take it all in and swallow it. Do not chew on it or crush it
  • You can take it along with food or without food. Actigra tablets should be taken at the same time daily to get the best results
  • Actigra 100 mg should be taken at least an hour before sexual activity and, if possible, before a meal
  • You should avoid the chances of overdose as it can cause side effects
  • Get medical help immediately if you somehow take the overdose
