I'm sorry to hear you're experiencing ear fluid imbalance along with nausea and giddiness. These symptoms can be quite uncomfortable.

Vertin 16 (commonly containing betahistine) and Stemetil MD (containing prochlorperazine maleate) are often prescribed to manage vertigo, nausea, and related symptoms. Since you are already taking these medications, it is important to use any additional medicines cautiously.

Key points to consider:

• Both Vertin and Stemetil work to reduce dizziness and nausea, so taking extra medicines "only when needed" should be discussed with your doctor to avoid overlapping effects or side effects.
• Stemetil can cause drowsiness and dizziness, so adding other medications without guidance might increase these risks.
• If your symptoms persist, worsen, or if you feel the current medications are insufficient, it is essential to consult your ENT (ear, nose, and throat) specialist or neurologist for a thorough evaluation and possible adjustment of your treatment.
• Avoid self-medicating or adding other drugs without professional advice.

Recommendation: Please consult your ENT specialist or neurologist before taking any additional medicines alongside Vertin 16 and Stemetil MD to ensure safe and effective management of your symptoms. If you experience severe dizziness, vomiting, or any new symptoms, seek medical attention promptly.To narrow down potential causes, we will need some more information.I understand you're dealing with ear fluid imbalance, nausea, and giddiness.
