Are you also worried about psoriasis? Or do you wake up in the morning with stiff and swollen joints? We know how difficult it is to live with such conditions. So, your doctor may have prescribed you a vaccine called Secukinumab to control these diseases. If the name sounds a bit complicated, don't worry. Today, we will talk in a very simple way about this medicine, how to use it, and what you need to be careful about.
What exactly is Secukinumab?
Simply put, Secukinumab is a special type of vaccine that controls some of the activities of our body's immune system. You may also see it under the brand name Cosentyx. Our body's immune system sometimes becomes overactive and starts attacking our own cells. This is when skin conditions like psoriasis and various types of arthritis occur. This medicine works by controlling that unwanted immune response.
There are several conditions for which this medicine is mainly used:
- Psoriasis: A condition in which red patches of skin develop, covered with a silvery, scaly layer.
- Psoriatic Arthritis: Swelling and pain in the joints that occur with psoriasis.
- Ankylosing Spondylitis: An inflammatory condition that mainly affects the joints of the spine.
- Other inflammatory joint conditions: It is also used for some other joint conditions that the doctor determines are appropriate.
