Product Information


Vikalis Vx is a drug proven effective in treating mild to severe cases of erectile dysfunction in men. Erectile dysfunction is a medical condition characterized by a man’s inability to achieve and maintain proper erection due to the narrowing of penile arteries. 


Vikalis Vx contains 20mg of Tadalafil as its active ingredient. Tadalafil is a drug that blocks the action of the enzyme PDE5 to help relax the muscles of blood vessels walls, causing the blood vessels to dilate or widen and improve blood flow to the penis. Through this mechanism, Vikalis is able to help men achieve and maintain hard and strong erections for a satisfactory sexual intercourse.


Sexual stimulation or arousal must be done in order for Vikalis Vx to work. This drug is also called the “Weekend pill” because of its long duration of action. This tablet does not an aphrodisiac and does not protect against sexually transmitted diseases.




Vikalis VX is manufactured by Shree Venkatesh Int. Ltd.




Consulting a physician is necessary prior to using Vikalis Vx to receive the appropriate dosage. Tadalafil may be used on an “as needed” basis or “once daily” use. Below are the recommended dosages of Tadalafil:


As needed for erectile dysfunction:

  • An initial dose of 10mg taken orally once, as needed, at least 30 minutes before a planned sexual activity.
  • The next dose may be adjusted, decreased to 5mg or increased to 20mg, depending on efficacy and tolerance.

Tadalafil has been shown to improve erectile dysfunction up to 36 hours when used as needed. 10 to 20mg of Tadalafil must only be taken as needed, not for daily use. Dose should not exceed one dose in a period of 24 hours.


Once daily use for erectile dysfunction:

  • An initial dose of 2.5mg taken orally, once daily about the same time each day, without regard to time of sexual activity.
  • Maintenance dose may be adjusted from 2.5mg to 5mg once daily, depending on efficacy and tolerance.
  • If a dose is missed, take it as soon as remembered but skip it if its almost time for the next dose then resume to regular dosing schedule. A dose must not be doubled to make up for the missed dose.


A tablet of Vikalis Vx must be swallowed whole with a glassful of water. It may be taken without regard for food because food does not affect its effectiveness.




Vikalis Vx is contraindicated to patients who are allergic to the active ingredient Tadalafil, and to any of the tablet’s inactive ingredients.


It is also contraindicated to patients taking medicines to treat pulmonary arterial hypertension such as Riociguat, taking nitrate drugs for heart problems, and recreational drugs containing nitrates as it may cause a serious decrease in blood pressure.
