Prapannas having surrendered unto Perumal for moksham, are not supposed to worship demi-gods for remedy from pitru dosham, stree sapam (curse) and naga dosham. Are there any Vedanta Desika slokas that can be recited as a remedy from such doshams? Adiyen had listened to Daya Shatakam upanyasam for pitru dosham.

Those who have performed Sharanagati must not worship demi-gods for any reason. One must have total faith in Emperuman and that he will destroy all doshams. One can worship Perumal directly and worship his servitors like Garuda and Vishvakshenar.
Notes:
Listening to Daya Shataka upanyasam is the best remedy for pitru dosham.
To be absolved from naga dosham one can learn and recite Garuda Panchasat.
For revival from the curse of women, recite Sri Stuti, Bhu Stuti and Godha Stuti
For remedy from Navagraha doshami, chanting Paduka Sahasram will be beneficial.
In our sampradayam reciting Swami Desikan’s stotras will remove all dosham.
As all the demi-gods are under the control of Emperuman, a prapanna can directly approach Emperuman as all others are His subjugates.
