Risks of Hydroxychloroquine and Cevimeline During Pregnancy: What to Know - Internal Medicine

Share to:

Diagnosed with Guillain-Barré Syndrome, is medication dangerous for children?


Hello Doctor, I have been diagnosed with Sjögren's syndrome and I am currently taking Hydroxychloroquine sulfate 200 mg (Plaquenil) and Cevimeline 30 mg (Evoxac), both once daily.
However, I was unaware that I was pregnant until I discovered it at six weeks.
I have been taking Hydroxychloroquine daily, and I took Cevimeline daily until four weeks into the pregnancy, after which I only took it about twice a week for the last two weeks because I consulted a pharmacist and learned that both medications are classified as Category C.
Is there a significant risk of teratogenic effects on the fetus? Could you please provide some advice on how to proceed?

Dr. Zeng Guosen reply Internal Medicine


Hydroxychloroquine sulfate and Cevimeline are both classified as Category C medications, which means that the benefits and risks of their use must be carefully weighed.
It is important to assess your condition before making any medication decisions, so it is advisable to return for a follow-up appointment and discuss this with your treating physician.
Thank you for your question.

When considering the use of Hydroxychloroquine and Cevimeline during pregnancy, it is essential to understand the potential risks and benefits associated with these medications, particularly for individuals diagnosed with Sjögren's syndrome. Both Hydroxychloroquine and Cevimeline are classified as Category C drugs by the FDA, which indicates that while animal reproduction studies have shown an adverse effect on the fetus, there are no adequate and well-controlled studies in pregnant women. This classification suggests that the potential benefits of the medication may outweigh the risks in certain situations.

Hydroxychloroquine is primarily used to manage autoimmune conditions, including lupus and rheumatoid arthritis, and is known for its anti-inflammatory properties. It has been used for many years and is generally considered safe during pregnancy, especially when the benefits of controlling the mother's disease outweigh the potential risks to the fetus. Some studies have indicated that Hydroxychloroquine does not significantly increase the risk of congenital malformations when used during pregnancy. However, it is crucial to monitor the mother’s health closely, as uncontrolled autoimmune diseases can pose a greater risk to both the mother and the fetus.

Cevimeline, on the other hand, is used to treat dry mouth associated with Sjögren's syndrome. While there is limited data on the use of Cevimeline during pregnancy, the available evidence suggests that it may not pose significant risks. However, due to its classification as a Category C drug, caution is advised. The decision to continue or discontinue Cevimeline during pregnancy should be made in consultation with a healthcare provider, considering the severity of the mother's symptoms and the potential impact on her quality of life.

In your case, since you were unaware of your pregnancy while taking these medications, it is understandable to have concerns about the potential effects on your developing fetus. The fact that you have been taking these medications for a limited period during early pregnancy (specifically during the first six weeks) is reassuring, as many medications taken during this time do not lead to adverse outcomes. However, it is essential to discuss your specific situation with your healthcare provider, who can provide personalized advice based on your medical history and the current state of your health.

If you are currently taking Hydroxychloroquine and have recently reduced your intake of Cevimeline, it may be beneficial to continue this approach while closely monitoring your health and any symptoms related to Sjögren's syndrome. Your healthcare provider may recommend regular check-ups to assess both your health and the development of the fetus.

In summary, while both Hydroxychloroquine and Cevimeline are classified as Category C drugs, the risks associated with their use during pregnancy appear to be relatively low, especially when the medications are necessary for managing significant health issues. It is crucial to maintain open communication with your healthcare provider to ensure the best possible outcomes for both you and your baby. If you have any further questions or concerns, do not hesitate to reach out to your healthcare team for guidance and support.
