Rare Side Effects of Emetrol: Persistent Milk Secretion Concerns - Pharmacology

Share to:

The side effect of Emetrol that is rarely reported is the secretion of breast milk?


I was prescribed Emetrol due to gastrointestinal issues.
After taking it for about two days, I started experiencing breast tenderness, and by the fourth day, I noticed milk leaking from my breasts.
It's been three days since I stopped the medication, but my breasts are still very swollen and continue to produce milk.
I would like to know how long it will take for this condition to resolve.
Thank you.

Generally, the side effects of medications will gradually resolve a few days after discontinuation.
The situation you are experiencing is due to the stimulation of prolactin secretion by the medication.
If your condition does not improve after stopping the medication, it is advisable to seek medical treatment.

More Info


Emetrol is an over-the-counter medication primarily used to relieve nausea and upset stomach. Its active ingredients typically include phosphorated carbohydrate solution, which works by soothing the stomach lining and reducing the urge to vomit. While Emetrol is generally considered safe for most individuals, it is important to be aware of potential side effects, especially when it comes to hormonal changes and milk secretion.

The symptoms you are experiencing, such as breast pain and persistent milk secretion, are not commonly associated with Emetrol. However, they may be indicative of a hormonal imbalance or other underlying issues. The secretion of milk from the breasts, known as galactorrhea, can occur due to various factors, including hormonal fluctuations, certain medications, or even stress. In your case, it is possible that the use of Emetrol has coincided with changes in your body that are leading to these symptoms.

The duration of galactorrhea can vary significantly from person to person. In many cases, if the underlying cause is resolved—such as discontinuing a medication that may be affecting hormone levels—the milk secretion may gradually decrease over a few days to weeks. Since you have already stopped taking Emetrol, it is reasonable to expect that your symptoms may improve over time. However, the persistence of breast pain and milk secretion for several days after discontinuation is concerning and warrants further evaluation.

It is crucial to consult with a healthcare professional regarding your symptoms. They may recommend a physical examination and possibly some blood tests to assess hormone levels, particularly prolactin, which is the hormone responsible for milk production. Elevated prolactin levels can lead to galactorrhea and may be influenced by various factors, including stress, certain medications, and other medical conditions.

In the meantime, here are some general recommendations to help manage your symptoms:
1. Avoid Stimulation: Try to avoid any stimulation of the breasts, including tight clothing or unnecessary touching, as this can exacerbate discomfort and potentially increase milk secretion.

2. Cold Compresses: Applying cold compresses to the breasts may help alleviate pain and swelling.

3. Hydration and Nutrition: Ensure you are staying hydrated and maintaining a balanced diet, as this can support overall health and hormonal balance.

4. Monitor Symptoms: Keep track of your symptoms, including any changes in breast pain or milk secretion, and report these to your healthcare provider.

5. Follow-Up: Schedule a follow-up appointment with your doctor to discuss your symptoms and any necessary tests or treatments.

In summary, while Emetrol is not typically associated with persistent milk secretion, your symptoms should be evaluated by a healthcare professional to rule out any underlying hormonal issues or other medical conditions. It is essential to address these concerns promptly to ensure your health and well-being.
