Virtue-enhancing drugs


The last menstrual period started on November 11, and it has been over 40 days without a period this month (previous cycles were about 28-30 days, and this is the first time the delay has exceeded 35 days).
I visited a clinic and a teaching hospital for examination, and there was no pregnancy, so the doctor prescribed Medroxyprogesterone (2 tablets daily for 7 days).
I started taking it on December 20, and since then, I have experienced diarrhea (5-8 times a day).

1.
Can taking Medroxyprogesterone cause diarrhea as a side effect? I did not find any mention of this side effect on the medication bag or online.

2.
Is it necessary to use contraception during the medication period? Is there a risk of becoming pregnant?
3.
Does this medication increase the risk of breast cancer? Is it safe for breast cancer patients to take?
4.
Is it necessary to complete the full 7 days of medication? If I feel very uncomfortable, can I stop taking it? Will my period still come after stopping the medication?

More Info


Medroxyprogesterone, commonly known by its brand name Provera, is a synthetic form of the hormone progesterone. It is often prescribed for various gynecological issues, including irregular menstrual cycles, endometriosis, and to help manage symptoms associated with menopause. However, like any medication, it can have side effects and specific considerations that patients should be aware of.

1. Side Effects: While abdominal discomfort and diarrhea are not commonly listed side effects of Medroxyprogesterone, individual reactions to medications can vary significantly. Some patients may experience gastrointestinal disturbances, including nausea or diarrhea, particularly when starting a new medication. If you are experiencing diarrhea (5-8 times a day), it is essential to discuss this with your healthcare provider, as it may not be directly related to the medication. Other common side effects of Medroxyprogesterone include mood changes, headaches, breast tenderness, and changes in menstrual flow. If the diarrhea persists or worsens, your doctor may consider adjusting your treatment plan or investigating other potential causes.

2. Pregnancy Considerations: Medroxyprogesterone is not a contraceptive and does not provide protection against pregnancy. If you are sexually active and not using another form of contraception, there is still a risk of becoming pregnant while taking this medication. It is advisable to discuss your contraceptive options with your healthcare provider, especially if you are concerned about the possibility of pregnancy during treatment.

3. Breast Cancer Risk: There has been some concern regarding the use of hormone replacement therapies, including Medroxyprogesterone, and their association with an increased risk of breast cancer. The risk appears to be more significant in women who have a history of breast cancer or those who have other risk factors for the disease. If you have a history of breast cancer or are currently undergoing treatment for it, it is crucial to have a thorough discussion with your oncologist or gynecologist before starting Medroxyprogesterone. They can help weigh the benefits and risks based on your individual health history.

4. Duration of Treatment: Medroxyprogesterone is typically prescribed for a specific duration, often around 7 days, to help induce a menstrual period or regulate the menstrual cycle. It is generally recommended to complete the full course as prescribed to achieve the desired therapeutic effect. However, if you are experiencing significant discomfort or adverse effects, it is essential to communicate this with your healthcare provider. They may advise you on whether it is safe to discontinue the medication early and what to expect regarding your menstrual cycle after stopping the medication.

In summary, while Medroxyprogesterone can be an effective treatment for various gynecological issues, it is essential to monitor for side effects and communicate any concerns with your healthcare provider. Each patient’s response to medication can differ, and your doctor can provide personalized advice based on your medical history and current symptoms. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for guidance.
