Rahu Dosha Is the Dispositor's Problem
What people call Rahu dosha is Rahu in the 6th, 8th, or 12th, or Rahu with the Sun or the Moon. The sign lord is the remedy's target, because Rahu acts through that dispositor. No rite shortens the 18-year mahadasha.

Define it or do not treat it
Rahu in the 3rd, 6th, 10th, or 11th is often read as an upachaya placement that can grow, not as a dosha. Rahu in the 8th or 12th is the hard house. Rahu with the Moon is the mind's version. Rahu with the Sun is the authority version. A shop that sells one Rahu remedy for all of these is not reading. If Saturn owns the sign, Saturday and Saturn's conduct are the match, and only if you are not dealing with a yogakaraka Saturn you meant to support for other reasons. If Mercury owns the sign, Wednesday is the match.
Gems and beads
Hessonite is the stone associated with Rahu and is not advised from a page. A rudraksha count is a poor substitute unless you know which mukhi a lineage assigns, and those assignments wander. Five-faced rudraksha is a Rudra bead, not a Rahu switch. The ordinary remedy is the dispositor's weekday during Rahu's antardasha or mahadasha, plus a clear look at the opposite Ketu house. If the dosha is Moon-Rahu, Monday joins the dispositor's day because the Moon is in the conjunction. One day for a conjunction that includes two grahas is incomplete. Two days, Moon and host, are enough. A third product is not.
The period ends on schedule
Rahu's 18 years end and Jupiter's 16 begin, in the standard order. If your birth balance started in the middle of Rahu, you will not live all 18, only the remainder, then Jupiter. Remedies do not change that date. They mark the years. When the mahadasha is over, stop calling every problem Rahu. The next lord has houses of its own. Ketu remains opposite Rahu in the natal chart forever. That axis is not a dosha that expires. Only the loud chapter expires.
Frequently asked questions
What should be called Rahu dosha?
Rahu in the 8th or 12th, or Rahu with the Sun or Moon. Rahu in an upachaya house is not the same label.
Whose weekday is the remedy?
The lord of Rahu's sign. Add Monday if the Moon is in the conjunction. Do not default to a gem.
Can the 18 years be cut short?
No. Only a birth balance that already consumed part of Rahu makes the lived portion shorter. The end date is still the Vimshottari date.
