Storage
- Powder (unmixed): −20 °C
- After mixing: 2–8 °C
- Use within: weeks
- Avoid freeze–thaw cycles
Technique
- Clean the vial stopper and the skin with an alcohol swab and let both air-dry.
- Pinch a skinfold and insert the needle at 45–90° into the subcutaneous tissue.
- Do not aspirate for subcutaneous injections — inject slowly and steadily.
- Wait 5–10 seconds before withdrawing, then apply gentle pressure. Do not rub the site.
- Rotate sites systematically — abdomen (at least 5 cm from the navel), thighs and upper arms — to avoid lipohypertrophy.
- Use a new sterile 28–31 G insulin syringe every time and dispose of it in a sharps container.
Safety & evidence
- Step the dose up by about 50 mcg every one to two weeks as tolerated.
- Generally well tolerated in human studies; occasional mild injection-site reactions.
- Research indicates DSIP does not induce pharmacological tolerance with continued use.
- Long-term safety data are limited — periodic breaks are recommended.
- Formal human studies mostly used 300 mcg daily or less.
