Let's learn about Azathioprine tablets. Has your doctor prescribed this medicine for you?

Have you or someone you know been prescribed a medicine called Azathioprine by a doctor? If so, it's important to learn a little about this medicine. Simply put, it's a medicine that suppresses or reduces the activity of your body's immune system. Let's take a look at what it does, how it's used, and what you need to be aware of.

What kind of medicine is Azathioprine? What is it used for?

Okay, let's first see what this drug called Azathioprine is mainly used for.

One of its main functions is to reduce the unnecessary stress on the body's immune system . The immune system in our body is like an army that protects a country. It fights germs that cause diseases. But sometimes this system becomes overactive and can harm our own body. That's when this medicine helps.

This is mainly used for:

1. After an organ transplant: Imagine that someone has received an organ transplant, such as a kidney or liver. Then the body's immune system may recognize this new organ as "foreign" and attack it. This is called "organ rejection." Azathioprine prevents this rejection. That is, it helps the new organ to adapt well to the body.

2. For diseases like Rheumatoid Arthritis: This is also a disease caused by a problem with the immune system, as I mentioned earlier. What happens here is that our own immune system attacks our own joints. So, Azathioprine helps reduce that attack and control the symptoms.

This medication may sometimes be prescribed by doctors for other conditions. If you have been prescribed this medication for another reason, it is best to ask your doctor about it. This medication is available in the market under names such as (Azasan) and (Imuran).

What are the important things I need to tell the doctor before starting this medication?

Before you start using Azathioprine, there are a few things you should definitely tell your doctor. It's important for your safety to be honest about these things, right?

The doctor wants to know if you have any of these conditions:

  • Any existing infection: If you have any infection such as fever, cold, cough. Because this medicine reduces immunity, infections may increase.
  • Kidney disease: If the kidneys are not working properly, it can affect how well the medicine is excreted from the body.
  • Liver disease: If there is a problem with the liver, it can also affect the medication.
  • If you have an allergic reaction to azathioprine, other medications, lactose, foods, dyes, or preservatives.
  • If you are pregnant or planning to become pregnant. This is very important, as this medicine can affect the baby in the womb.
  • If you are a breastfeeding mother.

When you discuss these points with your doctor, he or she can decide whether this medication is right for you or whether the dosage needs to be changed.

How exactly do you use Azathioprine?

Okay, now let's see how exactly to take this medicine.

This comes in the form of tablets. You should take this tablet with a glass of water. You should take it exactly as directed on the prescription label, at the time and in the amount prescribed by your doctor. Do not skip doses, and take them at the prescribed intervals.

Very important: Do not stop taking this medicine until your doctor tells you to, even if you feel a little better. Stopping it suddenly can cause problems. Never stop taking it or change the dose without your doctor's advice. Is it okay?

Should I give this medicine to small children?

Special care should be taken when giving this medicine to young children. Therefore, be sure to talk to a pediatrician before giving this medicine to your child.

What to do if you take too much medicine? (Overdosage)

If you think you have taken too much of this medicine by mistake, go to the nearest hospital emergency room or call a poison control center immediately. They will advise you on what to do. Don't waste time at a time like this.

Is it okay to give this medicine to others?

This is also important to remember. This medicine has been prescribed for you only. Do not give this medicine to a friend or family member who has the same symptoms as you. It can be dangerous.

What do you do if you miss a dose of medication?

Sometimes you may miss a dose. If you do, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time. Never take a double dose to make up for a missed dose. This can increase the risk of side effects.

What other medications may interact with Azathioprine? (Drug Interactions)

This is a very important part. Azathioprine can cause problems when combined with some other medications you are taking. It can even be dangerous to take it with some medications.

  • Mercaptopurine - This is a medication used to treat cancer and other conditions.

You should also be careful with these medications:

What should we be careful about when taking this medicine?

You need to take a little extra care of your health while taking Azathioprine.

  • See your doctor regularly: Visit your doctor at regular intervals to check your condition. You will need to have regular blood tests during the first few months of taking this medicine. This will help your doctor see if the medicine is working properly for you and if there are any side effects.
