No. Medication is made of different chemicals and is to be used because other alternative methods aren't working to the desired effect. Calories are measurable units that the body can use as fuel in order to function properly. Having said that, of course they are exceptions. If a person is fed via feeding tube, the formula they are given is a medication but it's a nutritional medication used to fuel them. That is very different than a person having for example allergies and taking medication to relieve them. Another point, the vast majority of medication is for all intents and purposes attempting to chemically alter/help the body not fuel the body, and calories equal fuel. To sum up, most medication doesn't have any measurable amount of calories the exceptions are to the medication that is meant to be a source of fuel such as people with feeding tubes. Hope this clears up any confusion!
