Also known as Pitocin (IV form)

What to expect

Most people tolerate Oxytocin Acetate well. Here is what is worth knowing going in, so nothing catches you by surprise.

The intranasal and troche forms are what people use recreationally and socially; the injectable is a prescription obstetric drug and is a different proposition entirely — leave that one to a clinician. How much intranasal oxytocin actually reaches the brain is still argued over in the literature. Keep doses modest: high doses pull water and can drop sodium. Effects on mood and social feeling depend heavily on context and are not always the pleasant ones.

Reconstitution guide

Oxytocin Acetate ships as a lyophilised powder and gets mixed with bacteriostatic water before use. How much water you add sets the concentration, which sets how many syringe units make up each dose. One unit on a U-100 syringe is 0.01 mL — the tables below do the arithmetic for the vial sizes you are most likely to be holding.

Standard steps

  1. Inspect the vialConfirm the label and that the powder cake is intact. Do not use a cracked or compromised vial.
  2. Let it reach room temperatureSitting out for a few minutes reduces condensation inside the vial when the seal is broken.
  3. Disinfect both stoppersWipe the compound vial and the bacteriostatic water vial with a fresh alcohol swab and let them air-dry.
  4. Draw the bacteriostatic waterUse a sterile syringe to draw the volume you have chosen from the reconstitution table.
  5. Add the water down the vial wallInject slowly so it runs down the inside wall rather than spraying directly onto the powder. This limits foaming.
  6. Dissolve gentlySwirl or roll the vial between your hands until the cake dissolves. Never shake — agitation damages peptide bonds. The solution should end up clear.
  7. Label and refrigerateWrite the reconstitution date and concentration on the vial. Store at 2–8°C. Do not freeze.
