The simple answer to why drugs have side effects is because no drug acts only where we want it to act. It acts at other places too. For example, if we develop a drug to act on the heart, just because of chemistry and biochemistry principles, it will more than likely also act someplace else, like maybe in the gut. So, while this drug might help the heart, it may also produce an upset stomach, for example. The pharmacological explanation for side effects is known as "selectivity". The more selective a drug is, the less likely it is to produce side effects. Pharmaceutical companies try all the time to make more and more selective drugs, but it is almost impossible. If they can find a dose of the drug that does only what they want, then that is fine, but higher doses will still act other places and cause side effects. Hope this helps.

The side effects of pharmaceutical drugs comes from the fact that the testers, makers and distributors of the drug do not treat the body as a whole. If they treat the symptom successfully they do not look at the effect it has on the other parts of the body. Holistic medicine is the only way to go in my book. Western medicine is a scam. Nobody is "fighting for a cure": it is all propaganda, f they actually cured a disease then they would be out of business. Think about it, if you were the leader of a major pharmacy and sponsoring lab testing for a new drug, would it be in your best interest to find the truth, or sweep it under the rug for the world to find out after it was all said and done and 100,000 people had to die but you can never be blamed because "the tests showed no evidence"... Blah blah blah. It's all about the money. Stay away from pharmaceuticals at all costs.

If you study physiology, you'd see that the human body is a complex thing. Any drug affects the whole body, and drug companies work to make drugs that are as selective as possible.
Many drugs work by activating or blocking receptors in the body. If you have a particular type of receptor in your heart and your lungs, it is nearly impossible to have the drug affect one without affecting the other. Therefore, side effects.
Drug companies DO try to minimize side effects. Better drugs = more profit.

Rule no 1) A drug that does not have side effects does not have any effects
Rule no 2)Every drug is a poison in large doses and every poison is a drug in small doses.
Rule no 3) The difference between therapeutic and toxic doses is the margin of safety.
Rule no 4)Only drugs having wide margin of safety are officially approved for use.
Rule no 5)Drugs with very narrow margin are poisonous/addicting/illegal/

no person's forcing you to. some human beings could die with out them. yet I agree which you're able to stability the income against the negative aspects of taking the medicine. playstation are you able to think of no longer having modern antibiotics once you get an infection? might desire to society have stored faraway from penicillin? What approximately polio, measles, hen pox, arthritis, heart illness, diabetes, allergies, HIV, and fever and so on. How could you manage them?

The human body is made up of many different systems.
A chemical that affects one is likely to also affect another.
It is impossible to avoid this.

because in America, we don't treat disease, we treat symptoms, therefore, side effects.....
