  • an active or chronic infection, including tuberculosis

    • Children are more susceptible to the effects of corticosteroids and the use of Kenalog-40 can lead to bone growth inhibition in pediatric patients and growth suppression

    Tell your doctor if you are pregnant or breastfeeding.

    Corticosteroids such as Kenalog-40 are teratogenic in many species when given in doses equivalent to the human dose and animal studies have shown a higher incidence of cleft palate in the offspring. There are no adequate and well-controlled studies in pregnant women. Administer only if the potential benefit justifies the risk.

    Systemically administered corticosteroids such as Kenalog-40 appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. Be cautious when administering to a breastfeeding woman.

    How to use Kenalog-40

    Kenalog-40 is given through a needle and can be injected into different areas of the body: into a muscle, into the space around a joint or tendon, or a lesion on the skin. A healthcare provider will give you this injection.

    Systemic (intramuscular)

    The initial dose of Kenalog-40 Injection may vary from 2.5 mg to 100 mg per day Depending on the condition being treated and the person being treated.

  • The suggested initial intramuscular dose is 60mg, injected deep into the gluteal muscle then dosage is usually adjusted within the range of 40mg to 80mg. Some patients may be controlled on dosages as low as 20mg or less.
  • The dose should be individualized and the lowest dose used to control the condition.
  • Single seasonal injections of 40mg to 100mg may be effective for patients with hay fever or pollen asthma not responding to conventional therapy.
  • For children, an initial dosage range of 0.11 to 1.6 mg/kg/day in 3 or 4 divided doses (3.2 to 48 mg/m2bsa/day) is suggested.

    • Intra-articular

    Single local injections are usually sufficient but several injections may be needed.

    Initial dose: 2.5mg – 5 mg (up to 10mg) for smaller joints and from 5mg – 15mg (up to 40mg)  for larger joints.

    Other information

    Kenalog-40 can weaken (suppress) your immune system, and you may get an infection more easily. Call your doctor if you have unusual bruising or bleeding, or signs of infection (fever, weakness, cold or flu symptoms, skin sores, diarrhea, frequent or recurring illness). Viral infections, such as chickenpox or measles may have a more serious or even fatal course in children and adults.

    Long-term use of steroids can cause harmful effects on the eyes. If you receive Kenalog-40 for longer than 6 weeks, your doctor may want you to have regular eye exams.

    Your doctor may instruct you to limit your salt intake while you are receiving Kenalog-40. You may also need to take potassium supplements. Follow all instructions.

    This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Kenalog-40.

    You should not stop using Kenalog-40 suddenly after long-term repeated use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.

    Warnings

  • Rarely, anaphylactic reactions have occurred in patients receiving corticosteroids, including triamcinolone acetonide injections.
  • Because Kenalog-40 is a suspension, it must not be administered intravenously.
  • You may not be able to receive Kenalog-40 if you have a fungal infection, or a condition called idiopathic thrombocytopenic purpura (ITP).
  • Kenalog-40 injection contains Benzyl Alcohol and exposure to excessive amounts has been associated with toxicity (such as hypotension and metabolic acidosis), particularly in neonates, and an increased risk of kernicterus (a type of brain damage caused by high levels of bilirubin in a baby's blood). The amount of benzyl alcohol that causes toxicity is unknown but the combined daily amount of benzyl alcohol from all sources must be considered.
  • If given intramuscularly, Kenalog-40 should be injected deeply into a large muscle, such as a gluteal muscle, rather than a deltoid muscle, because of the increased risk of local atrophy (shrinkage of tissue).
  • Kenalog-40 is long-acting and not useful in acute stress situations. Supportive corticosteroid treatments may be necessary in times of stress, such as trauma, surgery, or severe illness during treatment with Kenalog-40 and for a year afterward.
  • High dosages should not be used for the treatment of traumatic brain injury.

    • What other drugs will affect Kenalog-40

    Sometimes it is not safe to use certain medications at the SAMe time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
