Allergic Reactions
In Fiasp, insulin aspart acts as the active ingredient. The non-medicinal ingredients are arginine (as L-arginine HCl), disodium phosphate dihydrate, glycerol, metacresol, niacinamide (vitamin B3), phenol, water for injections, and zinc (as zinc acetate). You can adjust the pH by adding hydrochloric acid and sodium hydroxide.
Fiasp should not be used if you have a severe allergic reaction to the insulin or any of the ingredients in Fiasp. Consult your doctor immediately if you experience an allergic reaction.
A severe allergic reaction may have the following symptoms: local reactions (e.g., rashes, redness, itching) spreading to other parts of your body, feeling unwell with fever, becoming sick with vomiting, having difficulty breathing, experiencing rapid heartbeats, or feeling dizzy.
