Cortexin Dosage Calculator

Cortexin ships as a lyophilized powder in 5 mg or 10 mg vials. You'll reconstitute each vial with 1 to 2 mL of sterile water for injection right before use. Don't store the reconstituted solution; use it immediately. For a 10 mg vial reconstituted with 1 mL sterile water: you get 10 mg/mL concentration. Draw up 100 units (the full 1.0 mL) on a U100 insulin syringe for a 10 mg dose. For the 5 mg beginner dose from a 10 mg vial, draw 50 units (0.5 mL). For a 5 mg vial with 1 mL water, the full syringe is your dose. The non-obvious thing most beginners miss: you won't feel much during the 10-day course. Peak effects show up 1 to 4 weeks after the last injection. Evaluating at Day 10 is the single most common mistake; give it a full month before judging. If the injection hurts, switch your diluent from sterile water to 0.5% procaine solution (unless you have a local anesthetic allergy). Deep IM injection into deltoid or gluteal muscle, rotated daily, minimizes site reactions. Cold-chain matters; inspect the powder on arrival. It should be white to off-white. Discard if discolored, clumped, or if the vial seal is broken.
