Being a regular user of amlodipine and atenolol for controlling high blood pressure, I am somewhat aware of the power of prescription drugs.
I had carelessly taken more than what my doc had prescribed for a few days and my blood pressure went sharply in the other direction — from too high to too low.
Hollywood has seen some untimely deaths due to misuse of prescription drugs. Last year saw the death of Heath Ledger and this year has seen the death of Brittany Murphy. Michael Jackson's is a somewhat different story, I guess.
So, the lesson to learn is to beware of prescription drugs — these are not things to play with. These powerful substances can be extremely helpful to the body but when not used properly, they can cause havoc as well.
