Altavera Side Effects

Common Side Effects

Only vague information is available about Altavera side effects. It is difficult to obtain much information about side effects from studies that do not use a placebo (because there is no way of knowing if any particular problem is actually a side effect of the medication).
In fact, the side effects listed in the prescribing information for Altavera 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:
  • Breakthrough bleeding and spotting between periods (especially for the first few cycles)
  • 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)
  • Changes in sex drive (typically a decrease in sex drive).

Altavera Clinical Studies

Medications must undergo clinical studies before they are approved in the United States. With the clinical studies for most medications, one group of people receives the actual medication, while another group is given a placebo (a "sugar pill" that does not contain any active ingredients). 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.
