Product Information


Cockfoster is another alternative in treating erectile dysfunction. It contains 100mg of Sildenafil citrate as its active ingredient. With the presence of sexual stimulation, this drug works by increasing blood flow to the penis, to help men get and maintain an erection for a sexual activity.


Sildenafil belongs to the drug class called PDE5 inhibitors, which works by blocking the action of PDE5 in breaking down cGMP. cGMP is responsible for the relaxation of smooth muscles, resulting to the dilation of blood vessels to improve and increase blood flow to the penis.


This drug does not cure erectile dysfunction and does not protect against sexually transmitted diseases.




Cockfoster is manufactured by Shree Venkatesh Int. Ltd.

  • Adult dose – an initial dose of 50mg to be taken once a day as needed, about 30 minutes to 1 hours prior to anticipated sexual activity. Maintenance dose may be adjusted from 25mg to 100mg depending on patient’s tolerance and drug effectiveness.
  • Geriatric dose – men above 65 years of age should start with an initial dose of 25mg taken once a day as needed, about 30 minutes to 1 hour prior to anticipated sexual activity.
