Are there ways to control out of control tempers other than prescribed medicine?

meditation…....

or a taser

Biofeedback and relaxation techniques or cognitive behavioral therapy

What? No Haldol?

What @janbb said: CBT. This person needs to learn to recognize when the anger trigger is appearing, and how to let the trigger go away without pressing it. Even things as simple as counting to ten before screaming can work.

Therapy. I am assuming we are talking about someone over the age of 14. The person can learn how to think about situations differently, assuming there is no significant mental illness that might need medication in addition.

Angry people many times are people who have a lot of pain inside. They tend to think things should be a certain way, and when their expectations are not met, they flip out, they want to punish or control the person they perceive as hurting them. They may have unrealistic expectations, which need to be put into check, and they need to think less about how someone else should behave, should treat them, should do as they say. It is partly a control issues in my opinion. The angry person with a short temper wants control over his world and how it affects him.

People can learn to communicate better, become more self aware, and not resort to temper.

You could try letting out your anger in safe way, like running. I think Louise Hay has a CD on overcomming anger, and she is highly recommended. Visit a bookshop and go to the self-help section, see if there is anything there.

working out is great! furthermore martial arts + kickboxing can get a lotta energy out.

This person needs to learn to focus that energy towards a productive end.

Although I have not personally read it, I am told that this is an excellent book.

There was a russian sabre coach who came to new york and, to keep expenses down, opened his club in a less than desirable part of town. After witnessing a few gang fights and realizing that the atmosphere was severely cutting into his potential business, he approached the gang kids and said “Hey, want to learn how to fight with swords for real?”. The book was written by one of those “gang kids” who went on to become a very renowned sabre fencer/coach.

I suspect the same transition from angry street kid to world class athlete could apply to others with anger issues and to any sport they choose to use as an outlet.

Yoga helps. Mostly, being aware of yourself and the physical and emotional warning signs. My son and daughter are both bipolar and have a history of scary anger incidents. My daughter is not in denial. She has studied and knows when her body is beginning to become vulnerable. She surrounds herself with people who are accountability partners, and she asks often if her feelings are normal or part of her physical response. She also has gotten in touch with her spiritual side and has a higher power she draws on when that fight or flight (Mostly fight) feeling starts to come on. When things get real bad (less than once a month I’d say) she does take an anti anxiety medicine.
My son, (on the other hand) refuses to admit that he has a problem and continues to make decisions that get him in a pickle, and finds himself in that corner. He is not equipped to handle it because it still comes up on him by surprise and he has no real understanding of its effects on the people around him.

also, creative outlets can help like art, writing, graffiti, dance, etc.

How old is this person? Can the temper be a product of immaturity? Another thing I have seen, can the person be addicted to something? (cocaine, stimulants and even nicotine addiction can lead to/worsen tempers) The person has to see that their temper has become problematic first and then has to desire to seek help. I would recommend seeing a psychologist (not the one that prescribes medication) so they can help determine underlying issues which can be causing the temper.

This is what anger management therapy is for.

There is a link between Anger and Diet. source
The Anger Diet

I heard if a child is throwing a tempter tantrum, you are supposed to keep repeating back to them what they want. It instantly shuts them down. Example: “You want the candy! you want the candy! I know you want to candy! But you haven’t had dinner yet.” You end it by saying why it is not reasonable.

Behavioral therapy.
