Medically reviewed by Drugs.com on Jan 31, 2022. Written by Cerner Multum.
What is Kenalog-40?
Kenalog-40 is a steroid medicine that is used to treat many different types of inflammatory conditions, including severe allergic reactions, skin disorders, severe colitis, inflammation of the joints or tendons, blood cell disorders, inflammatory eye disorders, lung disorders, and problems caused by low adrenal gland hormones.
Kenalog-40 is also used to treat certain skin disorders caused by autoimmune conditions such as lupus, psoriasis, lichen planus, and others.
Different brands of triamcinolone injection have different uses.
Kenalog-40 may also be used for purposes not listed in this medication guide.
Warnings
You may not be able to receive Kenalog-40 if you have a fungal infection, or a condition called idiopathic thrombocytopenic purpura (ITP).
Before taking this medicine
You should not be treated with Kenalog-40 if you are allergic to it.
You may not be able to receive Kenalog-40 if you have a fungal infection, or a condition called idiopathic thrombocytopenic purpura (ITP).
Tell your doctor if you have ever had:
- an active or chronic infection, including tuberculosis;
- idiopathic thrombocytopenic purpura (ITP);
- high blood pressure, heart problems;
- cataracts, glaucoma, or herpes infection of the eyes;
- a parasite infection that causes diarrhea (such as threadworms);
- a nerve-muscle disorder, such as myasthenia gravis;
- a stomach ulcer, diverticulitis, ulcerative colitis;
- a colostomy or ileostomy, or stomach surgery;
- low bone mineral density; or
- a problem with your thyroid or adrenal gland.
Tell your doctor if you are pregnant or breastfeeding.
How is Kenalog-40 given?
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 into a lesion on the skin. A healthcare provider will give you this injection.
Not every brand of Kenalog-40 is used for the same conditions or injected into the same body areas. Some brands are given only one time as needed. Others may be given at regular intervals. Carefully follow your doctor’s dosing instructions.
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).
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.
What happens if I miss a dose?
Call your doctor for instructions if you miss an appointment for a scheduled Kenalog-40.
When Kenalog-40 is used as a single dose, you will not be on a regular dosing schedule.
What happens if I overdose?
Since Kenalog-40 is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
Using too much Kenalog-40 is not likely to cause serious problems. However, long term use of high doses can lead to thinning skin, easy bruising, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.
What should I avoid while receiving Kenalog-40?
After injection of triamcinolone into a joint, avoid overusing that joint through strenuous activity or high-impact sports. You could cause damage to the joint.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles. These conditions can be serious or even fatal in people who are using Kenalog-40.
Do not receive a “live” vaccine or a toxoid vaccine while using Kenalog-40, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine. Toxoid vaccines include diphtheria-tetanus toxoid (DT or Td).
Kenalog-40 side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Kenalog-40 may cause serious side effects. Call your doctor at once if you have:
- (after injection into a joint space) increased pain or swelling, joint stiffness, fever, and general ill feeling;
- blurred vision, tunnel vision, eye pain, or seeing halos around lights;
- unusual changes in mood or behavior;
- swelling, rapid weight gain, feeling short of breath;
- stomach cramps, vomiting, diarrhea, bloody or tarry stools, rectal irritation;

Certain side effects may be more likely with long-term use or repeated doses of triamcinolone injection.

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.
Tell your doctor about all your current medicines. Many drugs can affect Kenalog-40, especially:
- an antibiotic or antifungal medication;
- birth control pills or hormone replacement therapy;
- a blood thinner (warfarin, Coumadin, and others);
- a diuretic or “water pill”;
