for use as placebos
Explain the relationship between a placebo and a control?
there is no relationship. one is fake, one is the real deal. By me, placebos are controls and controls are not placebos....so this is alternate.
Why are placebos used in experiments?
To make it a fair test.
Why do scientists use placebos?
Because some people will have psycho-symatic reactions whether the drug is real or just a sugar pill.
Why is it important to have a control group for scientific experiments?
Often, scientific experiments come about because a scientist has a hunch that something may be the case. In these circumstances, it is therefore vitally important to guard against the experimenter's expectations clouding the results, as he or she may have a tendency to see what he or she wants to see. The best way currently known to achieve this is the double-blind control method. Say there are 100 subjects. A chemist prepares 50 genuine pills, and 50 identical-looking pills that do not contain the substance being tested (placebos). He puts them into bottles labelled 1-100, as randomly as possible, taking note of which bottle has a real pill and which a placebo, but he does not show this list to the experimenter. Thus neither the experimenter nor the subject know whether the pill is real or not (double blind). Therefore, when the patient reports the effects and the experimenter does her examination, neither can be influenced by prior expectation. Once the results are in, they are tabulated against the list of who got what, and the true effectiveness can be assessed honestly. With life-preserving drugs, giving a placebo may not be an option, so some of the protocol's protection may have to be sacrificed, say by comparing with the recorded effects of previous drugs that were supposed to do the same thing.

I ended my pack of birth control pills and took placebos for 2 days and then started my new pack I haven't got my period yet is it normal to skip a period even though I took placebos for 2 days?
Yes, that's absolutely normal.
Why do researchers use placebos and double blind designs?
Researchers use placebos to test the effectiveness of the drug on trial.
What are the most common side effects of placebos?
Nausea, dizziness, and upper respiratory infection are the most common side effects of placebos.
On a twenty one day pill pack with seven placebos i skipped the placebos last month to skip period. Now I want to have my period. When I take the placebos for the week do I have to use backup?
No. Skipping placebos lowers, not raises, your risk of pregnancy. There is no special need for backup during the placebo week if you took six straight weeks of active pills before that.

Placebos were used throughout the nineteenth century in blind assessments of medical treatments. These blind assessments were created to test controversial medical treatments of the time

Can one take rest of active pills in pack and not placebos because of bleeding due to one missed pill that was taken when realized because 2 and a half weeks of bleeding is miserable?
Yes, absolutely! If you missed a pill, there's no need to throw away the pack. Just as you did, you take the missed pill as soon as remembered, then continue with the pack. You can skip the placebos at the end of the pack as well and go right to the first active pill in the next pack.
What is the Psychological perspective for placebos?
The psychological perspective for placebos emphasizes the role of beliefs and expectations in shaping treatment outcomes. Placebo effects occur when a person's belief in a treatment's effectiveness leads to an improvement in symptoms, even though the treatment itself is inactive. Psychological factors such as conditioning, suggestibility, and the patient-provider relationship are thought to play a significant role in mediating these effects.
