According to the Ventolin package insert possible side effects of taking this drug include fast or irregular heartbeat, chest pain, shakiness, and nervousness. There is no documentation from the Ventolin, Proair, or Proventil package insert that any of these drugs cause any type of mood altering effect.
Each pill contains levonorgestrel, a synthetic version of the hormone progestin. Levonorgestrel has been used in birth control pills for over 35 years. Plan B One-Step contains a higher dose of levonorgestrel than that in regular birth control pills.
Side effects can include nausea, stomach pain and dizziness. Plan B One-Step stirred up controversy in 2009 when it was approved for use without a prescription for women and girls ages 17 and older. Girls younger than age 17 could also purchase the $50 pill, but only with a prescription. In April, the age limit was dropped from 17 to 15. Now the drug will be made available over the counter to all females who could potentially conceive a child.
