This practice should be avoided. Intramuscular triamcinolone acetonidecan last for 4 to 6 weeks in the body and can inhibit normal adrenalfunction. If the injection is given in hip fat tissue, it can cause subcutaneousfat necrosis.

Safe and effective low-dose topical nasal corticosteroids are nowavailable for first-line treatment of seasonal allergies. They can be used regularlyto control nasal symptoms for the entire pollen season without the adverseeffects seen with IM triamcinolone acetonide.
