How Ozempic Can Affect Your Menstrual Cycle and Periods

How Ozempic Can Affect Your Menstrual Cycle

Ozempic (semaglutide) is an injectable medication used to help manage blood sugar levels in people with type 2 diabetes. It belongs to a class of drugs called GLP-1 receptor agonists that work by mimicking the effects of an intestinal hormone called GLP-1 that lowers blood sugar after eating.

While Ozempic is highly effective at lowering blood glucose levels, some women have reported changes or disruptions to their normal menstrual cycle after starting treatment with this medication. Here's an overview of how Ozempic can impact menstruation and what to expect if you are taking this diabetes drug.

1. Ozempic May Cause Missed or Irregular Periods

One of the more common side effects of Ozempic for women is missed, delayed, or irregular menstrual periods. This can occur because Ozempic mimics the hormone GLP-1, which inhibits the release of other reproductive hormones like estrogen, progesterone, and gonadotropins from the pituitary gland.

The disruption of these reproductive hormones due to Ozempic can cause problems with ovulation, leading to irregular menstrual cycles, skipped periods, or what seems like “random” spotting between cycles. These issues tend to arise within the first 3-6 months after starting Ozempic but may continue as long as the medication is taken.

2. Periods Tend to Return to Normal After Stopping Ozempic

The good news is that for most women, menstrual irregularities caused by Ozempic are temporary. Typically within 1-3 cycles after discontinuing the medication, ovulation and menstrual periods will return to their normal pattern as reproductive hormone levels stabilize.

So if you experience missed or irregular cycles with Ozempic, this side effect should resolve after stopping the drug. However, let your doctor know if your periods remain irregular for several months after discontinuing Ozempic, as this may indicate an underlying gynecological problem.

3. Heavier or Lighter Period Flow

Some women report a change in their menstrual flow, either heavier or lighter, while taking Ozempic. Heavier periods may be caused by hormonal fluctuations or changes in the uterine lining triggered by the drug. Lighter periods can occur from inadequate estrogen levels or ovulation issues leading to a thinner endometrial lining.

These changes in flow, while annoying, are temporary and should return to normal after discontinuing Ozempic. But if you experience excessive bleeding or worsening period pain, be sure to follow up with your gynecologist promptly.

4. Earlier or Delayed Period Onset

Ozempic could alter the timing of when you get your period each month. Some women start getting their periods a week or more earlier than usual after starting this medication. For others, the opposite occurs, and their cycles are pushed back and start later than normal.

These effects occur because Ozempic interferes with the cyclical pattern of reproductive hormones that control the menstrual cycle. Rest assured your cycle should revert to its usual timing within a few months of stopping Ozempic.

5. Postmenopausal Bleeding

Women who are postmenopausal may experience vaginal bleeding while taking Ozempic, which is alarming since they no longer get a period. This occurs because Ozempic can stimulate the uterine lining, causing it to thicken enough to shed and result in spotting or bleeding episodes.

If you are postmenopausal and notice vaginal bleeding on Ozempic, report it to your healthcare provider. They may recommend stopping Ozempic and further evaluation to rule out more serious causes like endometrial cancer.

Other Possible Side Effects

Beyond impacts on menstruation, Ozempic can cause other hormonal side effects in women, including:

• Breast tenderness
• Mood changes or depression
• Changes in libido
• Hair thinning
• Acne outbreaks

These effects typically resolve within a few weeks or months after stopping treatment with Ozempic as hormone levels normalize.

Is it Safe to Take Ozempic if Planning Pregnancy?

Ozempic is not recommended for women who are pregnant or breastfeeding due to lack of safety data. It works by stimulating GLP-1 receptors, which are present in the placenta and could potentially impair fetal development.

There is also some evidence from animal studies suggesting Ozempic may increase the risk of thyroid tumors, including thyroid cancer. For this reason, it may be prudent to discontinue Ozempic at least 2-3 months before trying to conceive.

Discuss your plans for pregnancy with your healthcare provider so appropriate diabetes treatment adjustments can be made in advance if you are taking Ozempic.

The Bottom Line

Ozempic can lead to menstrual irregularities, but these side effects are expected to be temporary and resolve within 1-3 months of stopping the medication. Be sure to let your doctor know if you experience severe period issues, prolonged irregular cycles, or postmenopausal bleeding on Ozempic.

With a brief period of adjustment, most women find their cycles return to normal after discontinuing Ozempic. Work with your healthcare team to find the optimal diabetes treatment for your situation if planning pregnancy in the future.
