How many days after taking menstrual induction medication will menstruation occur?


Hello doctor, I am not currently pregnant.
I am planning to travel abroad on September 9 and would like to induce my period early.
My last menstrual period started on August 13, and my usual cycle is around 29 days.
I have been taking one tablet of Medroxyprogesterone daily since August 30, and I have taken five tablets so far.
If I want to take a total of ten tablets but am concerned about my period coinciding with my travel, can I stop after taking seven tablets? Thank you!

Tina, 30~39 year old female. Ask Date: 2023/08/30

More Info


When it comes to menstrual induction pills, it's essential to understand how they work and the implications of their use. Menstrual induction pills, such as those containing progesterone, are often prescribed to help regulate menstrual cycles or induce a period when necessary. In your case, you are looking to induce your period early to avoid having it during your travel.

Based on your description, you have already taken five pills and are considering whether to take two more or stop after seven. While I cannot provide personalized medical advice, I can offer some general information regarding the use of these medications.

Typically, menstrual induction pills are taken for a specific duration to allow the body to respond appropriately. If you are taking a medication like Medroxyprogesterone (often referred to as "美婷娜" in Chinese), it is usually recommended to take it for a set number of days, often around 10-14 days, depending on the specific protocol your doctor has provided. Stopping the medication early may not yield the desired effect of inducing a period, as the body may not have enough time to respond to the hormonal changes.

If you stop taking the pills after seven days, there is a possibility that your period may not start as expected. The timing of your menstrual cycle can be influenced by various factors, including hormonal balance, stress, and overall health. Therefore, if you are looking to induce your period effectively, it is generally advisable to follow the prescribed regimen closely.

Moreover, it is crucial to consider the potential side effects of hormonal medications. Some individuals may experience side effects such as mood swings, bloating, or changes in breast tenderness. If you have any underlying health conditions or are taking other medications, it is essential to consult with your healthcare provider before making any changes to your medication regimen.

In summary, while it may be tempting to stop taking the pills early to avoid potential side effects or complications, it is generally best to follow the prescribed course of treatment. If you have concerns about your menstrual cycle or the use of induction pills, I strongly recommend discussing them with your healthcare provider. They can provide personalized advice based on your medical history and specific circumstances.

Lastly, if you are looking to manage your menstrual cycle for travel or other reasons in the future, consider discussing long-term options with your healthcare provider. They may suggest alternative methods for cycle regulation that could be more suitable for your lifestyle and health needs.
