Dermojet Guidelines

The Dermojet is used to administer Triamcinolone Acetonide into the dermis. 

Diseases treated 
The Dermojet may be used by medical staff to treat a number of conditions including: 

  • alopecia areata 
  • granuloma annulare 
  • nodular lichenification (nodular prurigo) 
  • keloid scar 

Dermojet treatment given by nurses is normally restricted treatment of alopecia areata on the scalp using only triamcinolone acetonide 10mg/ml. 

Other conditions may occasionally be treated by nurses following discussion with Consultant Dermatologists. 

Medical staff will complete the blue treatment prescription cards. The drug, method of administration (Dermojet), area to be treated, frequency of treatment and total number of treatment should be specified. If no concentration is specified triamcinolone acetonide 10mg/ml should be used. 

Treatment is given as prescribed usually 4 to 6 treatments are given at intervals ranging from weekly to monthly. 

Gloves are worn.
The Dermojet if filled with 3ml of triamcinolone, then primed to ensure it is working effectively. The plastic spacer is attached, patient details are checked, and the procedure is explained. The area to be treated is assessed and cleaned with Chlorenhexidine Gluconate 0.05%. 

The triamcinolone ‘injections’ using the Dermojet are given approximately 1cm apart. A maximum of 30mg Triamcinolone (3ml) is given at any one treatment. 

Ensure the treatment area is clean and not oozing. A dry dressing may be required.
