Welcome to brain Stuff from how Stuff Works, Hey, brain Stuff, lauring vocal bomb. Here people turn to medications to help them feel better, but sometimes the inactive ingredients found in prescriptions can have just the opposite effect. While you might assume that only the active ingredients in a prescription are going to have any impact, the inactive components, which often make up more than half of every dose, can affect
you as well. The inclusion of inactive ingredients isn't optional, however, they perform necessary functions. They can help extend the life of the drug on the shelf or make drugs more palatable. Enactive ingredients are also necessary to simply hold the components of a tablet together, and there are critical part of many sustained and immediate release capsules. The actual active drug ingredients are usually only a small percentage of the complete drug.
Many times potentially problematic inactive ingredients are everyday allergens like lactose, peanut oil, dyes, sugars, and preservatives. Lactose and other types of sugars appear in about half of all medications and can cause gastro intestinal distress and patients. Other ingredients like gluten and peanut oil are less common, but can cause
much more severe reactions. So here's the good news. If you think you have an allergy, and especially a severe allergy to any of these components, you can consult an allergist to obtain a diagnosis, and then work with your doctor or pharmacy to identify what commercial medications contain inactive ingredients that you're sensitive to and what alternatives are available. Another option for people with specific requests who want an added layer of security is to turn to a compounding
pharmacy to fill their prescriptions. Before drugs were manufactured in mass, one size fits all quantities, all medications were compounded. That is, when a prescription came in, the active ingredient was handweighed and packaged specifically for the individual patient. So if you want to avoid gluten, or dyes, or peanut oil or all of the above, a compounding pharmacist can put it all together in a way that's in line with your
needs and preferences. Gelatine capsules have become something of a sticking point for people who wish to avoid animal products for personal or religious reasons. This is because gelatine is typically derived from mammal products, and often from cows. But these days alternatives made from other sources are available, capsules made from fish or vegetable products like seaweed. Our bodies are not one size fits all, and our medication doesn't have to be either. Today's episode was written by Ali A.
