Specific Precautions and Warnings With Lysteda

Warnings and precautions to be aware of prior to taking Lysteda include the following:
  • Lysteda may increase the risk of blood clots. A history of blood clots, genetic clotting disorders, and hormonal contraceptive use may increase this risk. Hormonal contraceptives include any type of birth control that contains hormones, such as birth control pills, patches, rings, and some intrauterine devices (IUDs).
  • In rare cases, this medication may cause severe allergic reactions. Seek immediate medical attention if you develop signs of an allergic reaction, such as:
    • An unexplained rash
    • Hives
    • Itching
    • Swelling of the mouth or throat
    • Wheezing
    • Difficulty breathing.
  • Lysteda can cause blood clots in the eyes. If you develop any vision changes or eye problems while taking it, contact your healthcare provider right away.
  • You should not take this medication if you have a subarachnoid hemorrhage (bleeding between the brain and the thin covering of the brain), as fluid accumulation in the brain and a stroke may occur.
  • Lysteda can potentially interact with a few other medications (see Lysteda Drug Interactions).
  • This drug is approved for use only in women with periods that occur at normal intervals. If your periods are more frequent, less frequent, or are otherwise irregular, a different treatment approach may be better.
  • Lysteda is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are not known (see Lysteda and Pregnancy). It is important to note that this drug is not intended for use during pregnancy.
  • Lysteda passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to beginning treatment (see Lysteda and Breastfeeding).
