Dr. Chen Shuzi reply Pharmacology


Amy: Hello! The medication information mentions Nilasen for dizziness (Betahistine 24mg/tab), and it should be used with caution in patients with pheochromocytoma.
This is because pheochromocytoma produces various hormones such as catecholamines, which can lead to symptoms like hypertension and dizziness, so users should be aware of this issue! There is no relevant concern regarding uterine fibroids and this medication, so it is safe to take Nilasen.
Remember to have regular follow-ups with your obstetrician-gynecologist for monitoring the uterine fibroids! Wishing you good health!

More Info


Nilasen, which contains Betahistine, is primarily used to treat vertigo and balance disorders associated with conditions like Meniere's disease. When considering its safety for individuals with uterine fibroids, it's essential to evaluate both the medication's profile and the nature of the fibroids.

Uterine fibroids, also known as leiomyomas, are benign tumors that develop in the uterus. They are quite common and can vary in size, number, and location. In your case, you mentioned having a fibroid approximately 9 cm in size. While fibroids can cause symptoms such as heavy menstrual bleeding, pelvic pain, and pressure symptoms, they are generally not considered a contraindication for the use of Betahistine.

The caution regarding Betahistine primarily relates to its use in patients with pheochromocytoma, a rare tumor of the adrenal gland that can lead to excessive catecholamine production and resultant hypertension. This warning is not directly related to uterine fibroids. Therefore, if you do not have pheochromocytoma or any other contraindications, it is generally considered safe to use Nilasen with uterine fibroids.

However, it is crucial to monitor your condition regularly, especially since you have a significant fibroid size. Regular follow-ups with your gynecologist or healthcare provider are essential to assess any changes in your fibroids or any symptoms you may experience. If you notice any new or worsening symptoms, such as increased pelvic pain or changes in menstrual patterns, you should report these to your healthcare provider promptly.

In summary, based on the information available, Nilasen (Betahistine) should be safe for you to use with your uterine fibroids, provided there are no other underlying health concerns. Always consult with your healthcare provider before starting any new medication, especially when you have pre-existing conditions like uterine fibroids. They can provide personalized advice and ensure that your treatment plan is safe and effective for your specific situation.
