Will Chronic Throat Inflammation Medications Affect Birth Control Pills? - Obstetrics and Gynecology

Share to:

I usually take oral contraceptives and would like to inquire about the effects of the medication!


I have been taking the contraceptive pill (Yueji) for about nine months.
Recently, I consulted a doctor due to chronic pharyngitis, and the doctor prescribed the following medications for me to take for seven days: Cochitong 500mg (acetaminophen), Domperidone 10mg, high-dose Bromelain, Hiros S.R.M Capsules, and Omeprazole 20mg.
Will these medications affect the contraceptive effectiveness of the birth control pill? Thank you!

More Info


When considering the interaction between chronic throat inflammation medications and birth control pills, it's essential to understand how certain medications can potentially affect the efficacy of hormonal contraceptives.
The birth control pill, commonly referred to as "the pill," works primarily by delivering hormones (estrogen and progestin) that prevent ovulation, thicken cervical mucus, and thin the uterine lining. For the most part, many medications do not interfere with the effectiveness of the pill. However, some specific medications can indeed reduce its effectiveness, leading to an increased risk of unintended pregnancy.

In your case, you mentioned taking several medications for chronic throat inflammation, including:
1. Cochitong 500mg (Acetaminophen): This is a common pain reliever and fever reducer. Acetaminophen does not affect the efficacy of birth control pills.

2. Domperidone 10mg: This medication is primarily used to treat nausea and vomiting. There is no evidence to suggest that domperidone affects the effectiveness of hormonal contraceptives.

3. Bromelain: This is an enzyme derived from pineapples, often used for its anti-inflammatory properties. There is no substantial evidence indicating that bromelain interacts with birth control pills.

4. Hiros S.R.M Capsules: The specific ingredients in this supplement would need to be evaluated, but generally, most dietary supplements do not affect hormonal contraceptives unless they contain specific herbs like St. John's Wort, which is known to reduce the effectiveness of birth control pills.

5. Omeprazole 20mg: This medication is a proton pump inhibitor used to treat gastroesophageal reflux disease (GERD) and other stomach acid-related conditions. There is no evidence that omeprazole affects the efficacy of birth control pills.

6. Actein: Without specific details about this medication, it's challenging to provide a definitive answer. However, if it is a standard over-the-counter medication or supplement, it is unlikely to interfere with hormonal contraceptives.

In summary, based on the medications you listed, none of them are known to significantly impact the effectiveness of your birth control pills. However, it is always prudent to consult with your healthcare provider or pharmacist regarding any new medications or supplements you are considering, especially when you are on hormonal contraceptives. They can provide personalized advice based on your health history and the specific formulations of the medications you are taking.

Additionally, if you are experiencing any side effects or have concerns about your chronic throat inflammation and its treatment, it is essential to communicate these with your healthcare provider. They can help you manage your symptoms effectively while ensuring that your birth control remains effective.
Lastly, if you ever find yourself in doubt about the effectiveness of your birth control due to medication interactions, consider using a backup contraceptive method, such as condoms, until you can confirm with your healthcare provider. This extra precaution can help alleviate any concerns about unintended pregnancy.
