If your doctor recently mentioned biologics, you might be wondering, what is a biologic? And what do they do? It may sound complex, but the concept is actually pretty straightforward once you break it down. Biologics are changing the way many serious conditions are treated, and knowing what they are can help you feel more in control of your health journey.
Biologics Are A Different Kind Of Medicine
Most medications you take are made from chemicals. A pharmacist or manufacturer combines specific chemical compounds to create a drug. Biologics work differently.
Biologics come from living sources. Scientists derive them from living cells, proteins, or other biological materials. That includes things like bacteria, yeast, or even human and animal cells.
Because they come from living matter, biologics are much more complex than traditional drugs. They are large, intricate molecules that target very specific parts of your immune system or body processes. Traditional medications are typically small molecules. Biologics can be hundreds of times larger.
What Conditions Do Biologics Treat?
Biologics treat a wide range of conditions. Many of them involve the immune system or inflammation. Here are some common examples:
- Rheumatoid arthritis
- Psoriasis and psoriatic arthritis
- Crohn’s disease and ulcerative colitis
- Ankylosing spondylitis
- Multiple sclerosis
- Certain cancers
- Asthma
These conditions used to be very difficult to manage. Biologics have helped many patients find relief when other treatments failed.
How Do Biologics Work?
Biologics target specific parts of your immune system. They block certain proteins or cells that drive inflammation or disease activity. Because of this precision, they often work better than older medications for certain conditions.
For example, some biologics block a protein called TNF (tumor necrosis factor). High TNF levels cause inflammation in diseases like rheumatoid arthritis. The biologic attaches to TNF and stops it from triggering that response.
This targeted approach means biologics can be very effective. It also means they affect the immune system directly, so your doctor will monitor you carefully during treatment.
How Are Biologics Given?
Most biologics cannot be taken as a pill. Because they are large protein molecules, your digestive system would simply break them down before they reach your bloodstream. That means they need to be delivered another way.
Some biologics are given as injections that you can do at home. Others require infusion therapy, where the medication drips slowly into your bloodstream through an IV. Infusion treatments typically happen in a clinical setting, such as Infusion Specialists. Our trained nurses oversee the whole process.
Infusion appointments can last anywhere from one to several hours. Many patients bring a book, watch a show, or just relax during their visit. Our team works hard to make every appointment as comfortable as possible.
Are Biologics Safe?
Biologics have a strong safety track record. That said, like any medication, they do carry some risks. Because biologics affect the immune system, they can sometimes increase the risk of certain infections. Your doctor will review your full health history before starting you on a biologic.
You will also have regular check-ins and lab work to make sure everything stays on track. The goal is always to find the most effective treatment with the fewest side effects.
Biosimilars: A Related Term Worth Knowing
You may also hear the term “biosimilar.” A biosimilar is essentially a copycat version of an already approved biologic. Once a biologic’s patent expires, other manufacturers can produce biosimilars. Biosimilars go through rigorous testing to prove they work the same way as the original.
Biosimilars can make biologic treatments more affordable and more accessible. Your doctor may discuss whether a biosimilar is right for your situation.
Starting Biologic Therapy
Starting any new medication brings up questions. That is completely normal. Your care team should explain what to expect, how often you need treatment, and what to watch for between appointments.
Infusion Specialists has a team ready to walk with you through the entire process. From your first appointment to ongoing infusions, you will never feel like just another patient walking through the door.
