Introduction

Synthetic corticosteroid.

Uses for Triamcinolone (EENT)

Allergic Rhinitis

Symptomatic treatment of seasonal or perennial allergic rhinitis.

Self-medication for temporary symptomatic relief of hay fever or other upper respiratory allergies.

Triamcinolone (EENT) Dosage and Administration

Administration

Intranasal Administration

Administer by nasal inhalation using a metered-dose nasal spray pump.

Prime metered-dose spray pump prior to first use and after a period of nonuse (i.e., ≥ 2 weeks).

Gently blow the nose to clear nasal passages. Shake inhaler well prior to administration.

Tilt head slightly backward, insert spray tip into one nostril, and point tip toward back of the nose. Pump the drug into one nostril while holding the other nostril closed and concurrently inspire through the nose. Repeat this procedure for the other nostril. Avoid blowing nose for 15 minutes after inhalation.

Dosage

Nasal spray pump delivers about 55 mcg of triamcinolone acetonide per metered spray.

Do not continue intranasal triamcinolone acetonide for >3 weeks in the absence of adequate symptomatic improvement.

For self-medication, discontinue therapy and contact a clinician if no improvement after 1 week.

Cautions for Triamcinolone (EENT)

Contraindications

• Known hypersensitivity to triamcinolone acetonide or any ingredient in the formulation.

Warnings/Precautions

Nasopharyngeal Effects

Epistaxis reported more frequently in patients receiving triamcinolone than in those receiving placebo.

Nasal septal perforation reported.

Localized candidal infections of the nose and pharynx reported rarely. Local or systemic treatment of such infections and/or discontinuance of intranasal therapy may be required. Periodically evaluate patients receiving the drug over several months or longer for evidence of candidal infections or other adverse nasal mucosal effects.

Avoid use until healing occurs in patients with recent nasal ulcers, surgery, or trauma.

Glaucoma and Cataracts

Nasally and orally inhaled corticosteroid use may result in glaucoma and/or cataracts; carefully monitor patients with vision changes or those with history of increased IOP, glaucoma, and/or cataracts.

Immunosuppressed Patients

Increased susceptibility to infections in patients receiving drugs that suppress the immune system. Certain infections (e.g., varicella [chickenpox], measles) can be serious or fatal in susceptible children or adults receiving corticosteroids. Not known how dosage, route, duration, or prior use of corticosteroid therapy and/or underlying disease affect risk of developing a disseminated infection.

Avoid exposure to varicella and measles in children or adults without history of or not properly immunized against these diseases. If exposure to varicella or measles occurs in such individuals, consider administering varicella zoster immune globulin (VZIG) or pooled IM immune globulin (IG), respectively. Consider treatment with antiviral agents if varicella develops.

Use with caution, if at all, in patients with clinical or asymptomatic Mycobacterium tuberculosis infections of the respiratory tract; untreated local or systemic fungal or bacterial infections; ocular herpes simplex; or systemic viral or parasitic infections.

Systemic Corticosteroid Effects

Possible reduction in growth velocity in pediatric patients. (See Pediatric Use under Cautions.)

Systemic corticosteroid effects (e.g., hypercorticism, adrenal suppression) may occur when intranasal corticosteroids used at higher than recommended dosages or in susceptible individuals at recommended dosages. If such effects occur, gradually discontinue the drug according to accepted procedures for discontinuing oral corticosteroid therapy.

Withdrawal of Systemic Corticosteroid Therapy

Possible corticosteroid withdrawal symptoms (e.g., joint pain, muscular pain, lassitude, depression), acute adrenal insufficiency, or severe symptomatic exacerbation of asthma or other clinical conditions if prolonged systemic corticosteroid therapy is replaced with topical corticosteroid therapy; careful monitoring recommended.

Sensitivity Reactions

Hypersensitivity reactions reported during postmarketing experience.

Specific Populations

Pregnancy

Category C. Use during pregnancy may result in hypoadrenalism in infants; monitor these infants carefully.

Lactation

Not known whether triamcinolone acetonide is distributed into milk. Caution if used in nursing women.

Pediatric Use

Safety and efficacy not established in children <2 years of age.

May reduce growth velocity; routinely monitor (e.g., via stadiometry) growth of children receiving this drug. Weigh benefits of therapy against possibility of growth suppression and risks and benefits of alternative therapies. To minimize systemic effects of intranasal triamcinolone, titrate dosage to lowest possible effective level.

Potential to cause growth suppression in susceptible patients and when used at higher than recommended dosages cannot be ruled out.

Geriatric Use

Insufficient experience in patients ≥65 years of age to determine whether geriatric patients respond differently than younger adults. No substantial differences in safety and efficacy observed relative to younger adults based on other clinical experience. (See Geriatric Patients under Dosage and Administration.)

Common Adverse Effects

Adults and children ≥12 years of age: Pharyngitis, epistaxis, increased cough.

Children 2–12 years of age: Flu syndrome, headache, increased cough, pharyngitis, pharyngolaryngeal pain, epistaxis, nasopharyngitis, bronchitis, asthma, rhinorrhea, dyspepsia, upper abdominal pain, diarrhea, tooth disorder, rash, excoriation.

Triamcinolone (EENT) Pharmacokinetics

20–25°C.

Actions

• Potent glucocorticoid and weak mineralocorticoid effects.

• May reduce the number of mediator cells (basophils, eosinophils, T-helper cells, mast cells, and neutrophils) in the nasal mucosa.

• Decreases nasal reactivity to allergens and decreases release of inflammatory mediators and proteolytic enzymes.

Advice to Patients

• Importance of instructing patients in the use of the nasal spray pump and to read the manufacturer’s patient information prior to using the drug.

• Risk of localized adverse nasal effects (e.g., epistaxis, nasal ulceration, candidal infections, nasal septal perforation, impaired wound healing).

• Risk of developing glaucoma or cataracts with intranasal corticosteroid use. Importance of informing clinician if vision changes occur during therapy.

• Importance of avoiding exposure to chickenpox or measles in patients receiving immunosuppressant doses of corticosteroids and, if exposed, of immediately consulting a clinician.

• Risk of worsening existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex.

• Importance of shaking container well prior to each use.

• Importance of children receiving therapy under adult supervision.

• Importance of taking the drug as directed and not exceeding the prescribed dosage. Importance of informing clinicians if symptoms worsen or fail to improve.

• Importance of following dosage instructions and not exceeding recommended dosages when used for self-medication. Importance of discontinuing use as self-medication, and consulting a clinician if symptoms fail to improve following 1 week of therapy.

• Importance of not using as self-medication for the common cold.

• Importance of advising patients to consult a clinician before using for self-medication following recent nasal ulcers or surgery, or a nasal injury not fully healed.

• Importance of advising patients to consult a clinician before using for self-medication in those receiving corticosteroids for asthma, allergies, or skin rash; with existing eye infections; or with existing or history of glaucoma or cataracts.

• Importance of advising patients to discontinue use for self-medication and to consult a clinician if they have existing chickenpox, measles, or tuberculosis or following contact with infected individuals.

• Importance of advising patients to discontinue use for self-medication and to consult a clinician if symptoms of infection (e.g., persistent fever), any vision changes, or severe or frequent nosebleeds occur.

• Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.

• Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.

• Importance of informing patients of other important precautionary information. (See Cautions.)
