Kineret

1 What is Kineret?

Brand: Kineret

Generic: Anakinra

Kineret belongs to a group of medicines termed as immunosuppressant which inhibits cellular/humoral or both types of immune responses. Such medications are preferably used in organ transplantation and autoimmune diseases. 

Indeed, anakinra is a recombinant human IL-1 receptor antagonist. It prevents IL-1 binding to its receptor and has been approved for use in refractory rheumatoid arthritis not controlled by conventional disease-modifying anti-rheumatic drugs (DMARDs).

This biological agent is also used to treat a very rare autoinflammatory syndrome, neonatal-onset multisystem inflammatory disease (NOMID) which is considered as the most severe as well as the rarest form of cryopyrin-associated periodic syndrome (CAPS). 

This medicine is available only with your doctor's prescription in solution form which is given to the patients by a healthcare professional through subcutaneous route.

2 What to Know Before Using

Before using Kineret, you must know all about the risks and complications associated with it.

If you are about to start a drug therapy, the risk-benefit ratio of taking the drug should be considered carefully. Here, the suitable drug therapy is chosen with active participation of both the doctor and the patient. 

There are some important factors such as drug interactions, metabolic impairment, hypersensitivity reaction, pregnancy, lactation etc. which may alter the desired therapeutic effects of such medications. 

Sometimes the presence of other health disorders affects the beneficial effects of this medicine and even may cause serious toxic effects. If you have had any allergic reactions to any medicine, you must inform your doctor about that. 

Further, make sure you mention your doctor if you have any other health problems or medical disorders, especially:

  • Allergy to E. coli-derived proteins or
  • Active infection or
  • Chronic infection (e.g. tuberculosis) or
  • Severely weakened state or
  • Malignancy or
  • Renal impairment 

In addition, certain drugs should not be used concurrently with such medications. For example, a higher incidence of serious infections has been reported in certain RA patients while receiving anakinra and etanercept therapy simultaneously. 

Thus, it is always advised to consult with your doctor if you are in need of some other medications or even any over-the-counter medicine for another health problem to achieve desired therapeutic effects. 

However, animal reproduction studies performed with anakinra have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women. 

Further, there is no evidence whether anakinra is excreted through breast milk. Thus, this medicine can be used during pregnancy and lactation if clearly needed.
