Larin Fe Side Effects

Clinical Studies on Contraceptives

Before medications are approved, they must undergo clinical studies to show that they are both safe and effective. In clinical studies for most medications, one group of people receives the medication, while another group is given a placebo (a "sugar pill" with no active ingredients). Usually, the people are not told if they were given the real medication or the placebo.
 
The side effects in both groups are carefully documented and compared. As a result, it is possible to see what side effects occurred, how often they appeared, and whether they are actual side effects of the medication. However, it is not possible to use a placebo in clinical trials for contraceptives, as this would lead to many unintentional pregnancies. Such studies are considered unethical.
 

Common Side Effects

Because birth control pills cannot be studied against a placebo, only vague information is available about Larin Fe side effects. In fact, the side effects listed in the prescribing information for Larin Fe are actually the possible side effects of all birth control pills in general.
 
Some of the common bothersome (but not usually dangerous) side effects of birth control pills include but are not limited to:
 
  • Nausea and vomiting
  • Changes in your eyes that make it more difficult to wear contact lenses
  • Bloating
  • Breast tenderness and swelling
  • Headaches (although birth control pills can improve headaches in some women)
  • Acne (although birth control pills can also improve acne)
  • Breakthrough bleeding and spotting between periods (especially for the first few cycles)
  • Changes in sex drive (typically a decrease in sex drive).
 
Women are often concerned about weight gain due to birth control pills, but recent research suggests that birth control pills probably do not cause weight gain for most women.
