Higher level Officials carry extra tablets in case of an emergency. If someone drops their tablet container, everyone must stop what they're doing until they find it. Parents carry their child's tablets until they're old enough to carry their own. Carrying their own tablet is the first step towards independence. Aberrations aren't allowed to carry tablets of their own.
In an interview with MatchedFandom.net  Ally Condie states that these look like dissolving Easter egg dye tablets. Example:
Blue tablets are received when children turn ten. The Society says that the tablet has enough nutrients to keep them alive for several days if they have water as well. However, this is not true. If a person ingests one blue tablet, they will become ill and die unless they receive medical attention from the Society. If they take more than one at once, they die quickly.
Oker explains that the Society engineered several other viruses when they made the original Plague. One of them could not be transmitted person to person. This virus is what is contained inside the blue pill. They named this virus the Cerulean Virus because it's another word for blue. The Society modified this virus and inserted it into the infant's immunizations. Then, if that person ingested a blue pill, it would trigger the virus. If the person ingests a blue pill and doesn't receive the cure from the Society, they will die.
At age thirteen, you are given a green tablet. Green tablets automatically calm you, which is especially nice if you're having an anxiety attack, or you need calming for a big presentation. You can take it up to once a week but only if the Officials don't take any notice.
Finally, at age sixteen you are given your third and final tablet-- the red tablet. The one you can only take when a high-level Official tells you to do so. There have always been rumors that the red tablet kills you, and the Officials have always said that it does not. As Cassia finds out when Ky is being taken away, all the red tablet does is clear your mind of everything of the last 12 hours. The effects of the tablet happen almost immediately, and the events of the past twelve hours are forgotten. Many people are immune to the effects of the tablet, including Ky Markham, Indie Holt, and Xander Carrow. Red tablets are not stored with the green and blue tablets.
Apart from Ky's abduction, there has been one other time in Cassia's lifetime that required Officials to make citizens use their red tablets. Xander knows what happened, but will not tell Cassia.
Red tablets are taken after traumatic events. The Society picks and chooses which events they want you to remember, and which will cause you to think badly of the Society. For example, after Matthew Markham died no tablet was required to be taken. This was so each member of Society would remember that an Anomaly will kill you, and that if the Society were to fail, you would be in danger. However, when Patrick Markham began to tell the truth about the War, he was silenced. Each member of Mapletree Borough who was on the street watching Ky being taken away had to take their red tablet, so that they would forget about the War and the way Ky went.
The disease-proofing tablets are given to babies on their Welcoming Day. They are round with three pie shaped divisions. One is blue, one is green and one is red. Although the tablet has the same colors of the adult versions, they do not serve the same purpose. The tablet's purpose is similar to shot immunizations that were given before the Society.
The Rising infiltrated the dispensaries where the disease-proofing tablets were made in order to alter these tablets. In the beginning, they could only make new tablets for those who they thought would be useful later on. For the past two years, every disease-proofing tablet was with the Rising's formula. The Rising's tablet included everything the Society used, but also included an immunity to the red tablet and to the Plague.
