I am glad you read the post. Your pharmacy needs to know of the combination of drugs. Please check with them before you even add one more over-the-counter or prescription drug. They will tell you about the cytochrome P450 for the drug and if it will cross react.
Let me make up a story to explain better. If you were the only customer in a store and somebody yelled fire you could run right out the open exit with no trouble. If you were a customer and there was only standing room because the store was filled with people....Then someone yelled fire. That one exit is going to take a long time to run through.
The reason you get the same effect with a reduced dose is because the drugs that you are using must exit through the same pathway. They can not get out of your body as fast and stay at a higher dose longer.
The danger is if you are given another drug on top of those drugs that requires that same exit pathway. Then a toxic overdose may happen. Please, please check the drugs before adding anything else.
Doctors do sometimes select drugs on purpose that enhance the dosage of each other.However, extreme care needs to be taken before adding any drug, vit., herbs or even grapefruit juice. Some drugs cause more problems than others. Some antihistamines had to be taken off the market.
Hope this helps explain it better?
