Parlodel may have side effects such as nausea, vomiting, abdominal pain, dizziness, facial flushing, orthostatic hypotension, insomnia, headache, nasal congestion, tinnitus, and abnormal liver function.
The usual dosage of Parlodel is 2.5 mg, with a recommended daily dose of 2.5 to 5 mg.
Another medication that can be used is cabergoline.
Whether the dosage of Parlodel can be reduced depends on the response of prolactin levels and the tumor.
Please discuss this further with your physician.

More Info

Parlodel (bromocriptine) is a medication commonly used to treat conditions related to pituitary tumors, particularly prolactinomas, which are tumors that produce excess prolactin. While it can be effective in reducing tumor size and alleviating symptoms associated with high prolactin levels, it is not without side effects. The symptoms you are experiencing—dizziness, nausea, nasal congestion, and rapid heartbeat—are indeed known side effects of bromocriptine.

Understanding the Side Effects
1. Dizziness and Nausea: These are common side effects, especially when starting the medication or increasing the dose. Bromocriptine can affect the central nervous system, leading to feelings of dizziness and gastrointestinal upset.

2. Nasal Congestion: This can occur due to the medication's effects on blood vessels and mucous membranes, leading to swelling and congestion.

3. Rapid Heartbeat: This may be a result of the medication's impact on the autonomic nervous system, which controls involuntary bodily functions, including heart rate.

Management of Side Effects
If these side effects are persistent or severe, it is crucial to discuss them with your healthcare provider. They may recommend several strategies:
- Adjusting the Dose: Sometimes, reducing the dose can help alleviate side effects while still providing therapeutic benefits. However, any changes to medication should only be made under the guidance of a healthcare professional.

- Timing of Doses: Taking the medication at a different time of day or with food may help mitigate some gastrointestinal side effects.

- Alternative Medications: If bromocriptine proves intolerable, there are alternative medications available for treating pituitary tumors. These may include cabergoline, which is another dopamine agonist that is often better tolerated and has a more favorable side effect profile.

Alternatives to Consider
1. Cabergoline: This is a newer dopamine agonist that is typically taken less frequently than bromocriptine and may cause fewer side effects. It is often preferred for the treatment of prolactinomas due to its efficacy and tolerability.

2. Surgery: In some cases, if the tumor is causing significant symptoms or does not respond to medication, surgical intervention may be necessary. This is generally considered when medication fails or if there are concerns about the tumor's growth.

3. Radiation Therapy: This is usually reserved for cases where medication and surgery are not effective or feasible. It can help shrink the tumor over time.

Conclusion
It is essential to maintain open communication with your healthcare provider regarding any side effects you experience while on Parlodel. They can help you weigh the benefits of continuing the medication against the side effects you are experiencing. If necessary, they can explore alternative treatment options that may be more suitable for your situation. Always consult your doctor before making any changes to your medication regimen, including dosage adjustments or switching to another medication. Your health and safety should always come first.
