Can Lamictal Affect Your Period — Can Lamictal Cause Menstrual Problems

Summary: Lamictal is a medication that is commonly prescribed for the treatment of bipolar disorder and epilepsy. Although it is generally considered to be safe and effective, some women who take Lamictal may experience changes in their menstrual cycle. In this article, we will explore the potential effects of Lamictal on periods and provide information on what you should do if you experience any abnormalities.

1. How Lamictal Works

Lamictal, also known by its generic name lamotrigine, is an anticonvulsant drug that works by reducing abnormal electrical activity in the brain. It does this by blocking the activity of certain neurotransmitters that cause seizures and mood disturbances. Lamictal is also used off-label to treat other conditions such as borderline personality disorder, depression, and post-traumatic stress disorder.

Lamictal can be used alone or in combination with other medications to manage symptoms of bipolar disorder. It is effective at preventing mood swings and reducing the frequency and severity of manic and depressive episodes. Lamictal is also known to improve cognitive function and quality of life for people with bipolar disorder.

In addition to its mood-stabilizing effects, Lamictal may also be used to treat epilepsy. It works by decreasing the activity of neurons in the brain that cause seizures. Lamictal is approved by the FDA for use in adults and children aged two years and older with certain types of seizures.

2. How Lamictal Affects Your Period

Lamictal has been linked to changes in menstrual cycles in some women. While these changes are not typically severe, they can be bothersome and lead to irregular periods or missed periods altogether. Some women also report experiencing heavier or lighter than usual bleeding during their periods while taking Lamictal.

The exact mechanism by which Lamictal affects menstrual cycles is not fully understood. However, it is thought to be related to the drug’s effects on hormone levels in the body. Specifically, Lamictal may alter the levels of estrogen and progesterone, two hormones that play key roles in regulating the menstrual cycle. Low levels of either hormone can lead to irregular periods or missed periods.

It is important to note that not all women who take Lamictal will experience changes in their menstrual cycles. Furthermore, even if you do experience changes, they may not necessarily be related to the medication. Other factors such as stress, weight changes, and certain medical conditions can also impact menstrual cycles.

3. What to Do If You Experience Changes in Your Period

If you experience changes in your period while taking Lamictal, it is important to discuss them with your healthcare provider. They may recommend monitoring your cycle for a few months to see if the changes persist. In some cases, your doctor may recommend adjusting your Lamictal dosage or switching to a different medication altogether to manage your symptoms without disrupting your menstrual cycle.

If you miss a period while taking Lamictal, it is possible that you could be pregnant. Lamictal has been linked to an increased risk of birth defects when taken during pregnancy, so it is important to inform your doctor if you suspect that you may be pregnant. You may be advised to undergo a pregnancy test to confirm your condition.

If you experience heavy bleeding, severe cramping, or other abnormal symptoms during your period while taking Lamictal, seek medical attention right away. These symptoms could be indicative of a more serious underlying condition that requires prompt treatment.

4. Other Potential Side Effects of Lamictal

In addition to changes in menstrual cycles, Lamictal may also cause a variety of other side effects. These can include:

– Headache
– Dizziness
– Nausea
– Insomnia
– Skin rash
– Blurred vision
– Tremors

If you experience any of these symptoms while taking Lamictal, notify your healthcare provider right away. You may be advised to adjust your dosage, switch to a different medication, or undergo additional testing to determine the cause of your symptoms.

5. How to Manage Potential Side Effects of Lamictal

If you are experiencing side effects from Lamictal, there are several steps you can take to manage them. These include:

– Take your medication as prescribed. Make sure you follow your doctor’s instructions carefully to ensure that you get the most benefit from your medication and minimize the risk of side effects.

– Keep track of your symptoms. If you notice any changes in your menstrual cycle or other side effects, write them down and discuss them with your healthcare provider at your next appointment.

– Practice self-care. Getting enough sleep, eating a healthy diet, and engaging in regular physical activity can help to reduce stress and improve your overall health.


Lamictal is a commonly used medication for the treatment of bipolar disorder and epilepsy. While it is generally considered safe and effective, some women may experience changes in their menstrual cycles while taking the drug. If you experience any abnormalities in your period while taking Lamictal, it is important to speak with your doctor. They can help to determine if the changes are related to the medication and recommend appropriate treatment options. With careful monitoring and management, most women can continue taking Lamictal without significant disruptions to their menstrual cycles or overall health.
