Are you tired of the pain and swelling caused by arthritis in your knee? Are you having a hard time walking, climbing stairs, or even bending your knee a little? This pain can make it difficult to do your daily tasks. Sometimes your doctor may recommend a special injection into the knee joint for this condition. Triamcinolone is one such injection. Today, we will talk about this in simple terms, what this injection does, who is it suitable for, and what are the things to be careful about.
What actually happens with this vaccine?
Simply put, this is a steroid type of medication. But it's not like the steroid pills we take by mouth. This is an injection that is injected directly into the painful knee joint. It is injected to control inflammation, which is the main cause of pain and swelling.
Another special feature of this is that it is an extended-release injection. This means that once you inject it, the medicine is gradually released into the joint, providing you with significant relief by controlling pain and swelling for perhaps several weeks. Zilretta is also a well-known brand name for this medication.
Things to tell your doctor before getting vaccinated
This is very important. Before you are given this vaccine, your doctor will need to know your complete health history. Be sure to tell them if you have any of the following conditions:
| Your health condition or problem | Things to pay special attention to |
|---|---|
| Existing infectious conditions | Any infection like tuberculosis, herpes, measles, chickenpox, fungal infections. |
| Diabetes | This vaccine may increase blood sugar levels. |
| High Blood Pressure | Blood pressure may increase further. |
| Heart disease or a recent heart attack | Heart function may be affected. |
| Other medical conditions | Glaucoma, liver disease, thyroid problems, Cushing's syndrome, myasthenia gravis, seizures, stomach or intestinal disease (e.g. ulcers). |
| Allergies | If you are allergic to triamcinolone, other steroids, benzyl alcohol, or any other medicine, food, or dye. |
| Pregnancy or breastfeeding | If you are pregnant, trying to get pregnant, or are a breastfeeding mother, it is very important. |
How is this vaccine given?
This is not a shot you can take home and give yourself. It must be given by your doctor or a trained medical staff member in a hospital or clinic. They will carefully inject the shot into your knee joint.
The most important thing is to follow your doctor's instructions exactly after the injection. For example, they may tell you not to put too much strain on your knee for a day or two.
Since this medicine is prescribed by a doctor in the prescribed dosage, the chances of an 'overdose' occurring are very low. However, if you suspect that something has happened, immediately call the National Poisons Information Centre at the Colombo National Hospital , or go to the Emergency Treatment Unit (ETU) of the nearest hospital.
Other medications that may interact with this medicine
Yes, some medications can interact with Triamcinolone injection, so it is very important to tell your doctor about all the medications you are taking (including vitamins, herbal remedies, and supplements).
- Antiviral drugs for HIV or AIDS
- Aspirin
- Some medications for fungal infections (e.g. Ketoconazole, Itraconazole)
- Some antibiotics, such as clarithromycin
- Mifepristone
- Nefazodone
- Other steroid medications (pills, creams, or inhalers)
- Vaccines
This list is not complete. So for your safety, please inform your doctor about everything you are taking.
Things to keep in mind when getting vaccinated
- Check-ups: Be sure to go to your doctor's appointments to check your condition.
- Protect yourself from infections: Steroids can slightly weaken your immune system. So, try to stay away from people who have illnesses like chickenpox or measles during this time. If you accidentally come into contact with someone like that, tell your doctor immediately.
- Blood sugar levels: As we mentioned earlier, this vaccine can increase blood sugar levels. If you have diabetes, check your blood sugar levels regularly. Also, talk to your doctor about any changes you need to make to your diet or diabetes medication.
- An identification card: If you have to receive this vaccine for a long time, it is wise to carry a card with your name, the name of the medicine, the dosage, and your doctor's details.
