Do I need to stop taking birth control pills before a colonoscopy?


Hello Doctor, I have scheduled a colonoscopy, but I usually take oral contraceptives (Mireille).
Should I stop taking them? Will it affect the results of the examination? Thank you, Doctor.

There is no need to stop medication; it is important to drink plenty of water during bowel cleansing.

More Info


When preparing for a colonoscopy, patients often have questions regarding their medications, including birth control pills. In general, it is not necessary to stop taking birth control pills before a colonoscopy. The hormonal contraceptives, such as the one you mentioned (likely a combination of estrogen and progestin), do not interfere with the procedure or its results.
The primary concerns before a colonoscopy are related to the bowel preparation and ensuring that the colon is adequately cleansed for optimal visualization. This typically involves following a specific diet and taking laxatives as directed by your healthcare provider. The effectiveness of the bowel prep is crucial because any residual stool can obscure the view of the colon and potentially lead to missed lesions or polyps.

It is important to communicate with your healthcare provider about all medications you are taking, including birth control pills. While they do not affect the colonoscopy directly, your doctor may want to ensure that you are aware of any other medications that might need to be adjusted or paused, particularly those that could affect bleeding or sedation during the procedure. For instance, if you are taking any anticoagulants or non-steroidal anti-inflammatory drugs (NSAIDs), your doctor may advise you to stop those prior to the procedure to minimize the risk of bleeding.

In summary, you do not need to stop taking your birth control pills before a colonoscopy, and doing so will not impact the results of the examination. However, always follow the specific instructions provided by your healthcare provider regarding any other medications and the bowel preparation process. If you have any concerns or further questions, it’s best to discuss them with your doctor to ensure a smooth and successful procedure.
