definitely not. this is true for all tablets, capsule (and even syrups). it is very dangerous to inject any of the above mentioned dosage form because:
1. they are not sterile like IV/IM preparations packaged in vials and ampules.
2. they are still in their "unreleased form" (applicable for tablets and capsules)
3. they may block your veins as their minute size may still occlude passages.
