I am a senior physician, and has been involved directly with clinical trial safety of participants since last few yrs.
I have few questions for you to answer your concerns better:
1. Are you already enrolled in the trial?
2. Which phase of study/trial is this ?
3. What is the indication/disease for which Potassium Chloride
going to be tested for?
4. Do you have any existing diseases? If yes, are you taking any medications for them? Please mention all including multivitamin/mineral supplements you are taking currently and/or expected to take during the trial participation?
As a rule, in any trial, participants are required to follow specific defined protocol of Dos & Don't's strictly. They will tell you the details of the trial if you ask for. There is a process called "Informed Consent" before enrolling every participant in any trial as required by health authorities. Informed consent provides the participants all rights to ask questions
, clarification of concerns, regimen (protocol plan of trial) and then choose to participate of even withdraw from trial.
I can provide you with details on participating a trial if you want. I can answer specific questions on risk involved with Potassium Cholride administration after getting your response on above mentioned questions.
