Changing birth control brands?

Hello doctor, my girlfriend has been taking birth control pills for a month.
She is on YAZ, and her period started on November 21.
So theoretically, she should start the next month's oral contraceptive on November 27.
However, after taking the first pill of the new pack, she realized that she bought the wrong one, which is Delyla.
She also came across some news online regarding the side effects of Delyla.
Therefore, I would like to ask if she can switch back to YAZ the next day (November 28).
Thank you.

More Info

Switching birth control pills mid-cycle can be a concern for many women, especially when there are questions about the safety and effectiveness of different brands. In your case, your girlfriend has been taking a specific brand of birth control pill (Yaz) for a month and is now considering switching to a different brand (Diane-35) after taking just one pill from the new pack.
Generally speaking, it is possible to switch birth control pills mid-cycle, but there are some important considerations to keep in mind. First, it is crucial to understand that different brands of birth control pills may have different hormone compositions, dosages, and mechanisms of action. This means that switching from one brand to another can potentially affect the effectiveness of the contraceptive method and may also lead to side effects.

In your girlfriend's situation, since she has only taken one pill from the new brand (Diane-35), she can switch back to her original brand (Yaz) the next day (November 28). However, it is important to note that she should not take both brands simultaneously, as this could lead to an overdose of hormones and increase the risk of side effects.
When switching back to Yaz, she should continue taking the pills as directed, starting from the first pill of the new pack. It is also advisable for her to use a backup method of contraception, such as condoms, for at least the first seven days after switching back to ensure that she is adequately protected against unintended pregnancy. This is particularly important if she had unprotected intercourse during the time she was taking Diane-35.

Additionally, if your girlfriend has any concerns about the side effects of Diane-35 or if she experiences any unusual symptoms after switching, she should consult her healthcare provider. They can provide personalized advice based on her medical history and any potential interactions with other medications she may be taking.

In summary, while it is generally safe to switch birth control pills mid-cycle, it is essential to do so carefully and with consideration of the potential effects on contraceptive efficacy and side effects. Communication with a healthcare provider is key to ensuring that the transition is smooth and that your girlfriend remains protected against unintended pregnancy.
