Frequently Asked Questions

Dostinex ke aam side effects kya hain?

Common side effects of Dostinex include nausea, vomiting, headache, dizziness, fatigue, and BP drop when standing. These are more common at the start of treatment. Taking it with food significantly reduces nausea. Most patients gradually adjust.

Dostinex ki pehli dose par kya hota hai?

BP may drop after the first dose (postural hypotension) — it is therefore better to take the first dose in the evening while lying down. Rising quickly may cause dizziness or fainting — stand up slowly. This generally improves after a few doses.

Kya Dostinex heart par asar karta hai?

At high doses there is a risk of fibrotic thickening of the heart valves (valvulopathy). At standard prolactin-treatment doses the risk is very low. Doctors may recommend echocardiography in high-risk patients.

Impulse control disorder kya hota hai Dostinex mein?

In some patients, dopamine agonists (including cabergoline) can cause compulsive behaviors — such as pathological gambling or hypersexuality. This is a dopamine agonist class effect. If you or your family notice these changes, IMMEDIATELY inform your doctor.

Kya Dostinex pregnancy mein safe hai?

Cabergoline is used for infertility — it is generally discontinued when pregnancy is confirmed. The decision to continue during pregnancy is made by the doctor. Do not stop or continue on your own — consult your doctor.
