An organ transplant is like a second life. It is truly life-changing. After this major surgery, the biggest challenge is to keep your body from rejecting the new organ (for example, a kidney or liver) that has been transplanted into your body. The medications you receive for it can sometimes cause minor side effects. While this may sound a little scary, there are actually ways to live successfully with these things. Let's be clear about them.

Why do these side effects occur?

Simply put, your body's immune system is like an army that protects a country. Its job is to fight and destroy any foreign substances (like viruses or bacteria) that come in. So, since the new organ that you have transplanted is also foreign to your body, your immune system tries to attack it. To stop this, your doctor will give you medications called immunosuppressants . These medications work by reducing the power of that army and stopping it from attacking the new organ. This is essential. But because these medications affect the entire body, some side effects can occur. The good news is that these side effects are much easier to manage than they used to be. Also, not everyone will experience all of these side effects.

What are the most common side effects?

These things can vary depending on the combination of medications you are given. But these are some of the common conditions that can be seen. Don't be alarmed by this list, one or two of these may or may not occur.

Side effect category	Possible situations
Digestive system problems	Vomiting and nausea, diarrhea
Common physical discomforts	Headaches, tremors, insomnia, swelling and numbness of the limbs
Changes in appearance and skin	Puffy face, acne and other skin problems, hair loss or unwanted hair growth
Metabolic Changes	High blood pressure, high cholesterol, diabetes, anemia
Bones and muscles	Bone weakness, arthritis
Changes in behavior and eating patterns	Increased appetite, weight gain, mood swings

Yes, this is a long list. But I repeat, not all of these things happen to everyone . These things vary from person to person. Some people may lose nothing, while others may gain one or two. The most important thing is not to be afraid of this.

Be sure to tell your doctor about any minor changes or side effects you experience. Don't suffer in vain. You may be able to control these conditions by changing the type or dosage of the medication.

Additional medications to control side effects

In some cases, you may need to take several other medications to control the side effects of the main type of immunosuppressant. For example:

Antibiotics , antifungal , and antiviral medications : Because your immune system is weakened, you can easily get bacterial infections. These medications can help prevent or treat them.
Anti- ulcer medications: Some medications can cause conditions like stomach ulcers and gastritis. These are given to control them.
Medicines that reduce water in the body ( Diuretics ):These help control excessive water retention in the body (edema) or high blood pressure.

Most of the time, these additional medications are only needed at the beginning of treatment. Over time, your doctor will gradually reduce the dose of your main medication. These side effects may then be greatly reduced or go away completely.

Drug Interactions - Be very careful about this!

Because a transplant recipient takes several medications at the same time, there is a risk of drug interactions. This is a very important issue. One drug can reduce the effectiveness of another drug, increase it, or cause new side effects. Therefore, it is important to keep your doctor informed about all the medications you are taking. This means:

Medicine prescribed by a doctor for another illness.
Medicines that you simply buy from a pharmacy (e.g. painkillers, cold pills).
Ayurvedic, Sinhala medicine or other traditional herbal remedies.
Vitamins or other supplements.

Remember, even some foods can interact with medications. An example is Grapefruit juice . Taking it with some medications can increase the effects of the medication unnecessarily. Therefore, don't start anything without asking your doctor.
