Take 25 mg of atenolol day.i've decided to stop it, been taking ever other day past 4 days. should i start breaking dose half.or just keep doing this?

Why?: Have you discussed this with your doctor? It is always wise to have a discussion with the doctor who prescribed your medication before you stop or self-wean. Usually, to stop Atenolol, you don't have to wean yourself. But, if you're stopping b/c you don't think it's working or due to certain side effects, you should discuss your concerns, and your doctor can come up with a better plan for you.

Why,dont, see PCP: At your age if you are on Atenolol there has to be a steong reason. I stongly advice consulting with the physician who started this medication before making changes on your own! If you choose to not go back to original dose, then the safer is option is 12.5 daily. Again right thing is to continue original dose and talk to the doc who put u on it.

Medication motives?: First, why are you on Atenolol? If it is for high blood pressure or palpitations, it may not be a good idea to stop without notifying the prescribing doctor. However, if you are going to stop the medication anyway, there is not much else to do but stop. You are taking the lowest dose to start with, so stopping now should not be a problem (unless you are losing control of a problem). Good luck.

Why take it?: I guess it depends on why this was prescribed for you in the first place! My guess it was for palpitations and not organic heart disease! If this is the case then stop the medicine at this point, if you have significant symptoms such as fainting, chest pain then please go to the hospital or contact the physician who gave this drug to you in the first place!
