What causes acid reflux, dizziness, and drowsiness after taking Miseanlin, and what should be done?

Mi'anserine beige tablets, also known as mianserin hydrochloride tablets, may cause symptoms such as acid reflux, dizziness, and drowsiness after administration. These symptoms could be due to adverse drug reactions, overdose, allergic reactions, or other causes. Appropriate management should be based on the specific underlying cause. The detailed analysis is as follows:

1. Adverse Drug Reaction

Mianserin hydrochloride tablets are clinically used for the treatment of depression. After taking the medication, patients may experience anticholinergic effects, presenting as dry mouth, drowsiness, acid regurgitation, dizziness, and other discomforts. These symptoms are usually mild and considered part of the drug's adverse reactions, which typically resolve spontaneously.

2. Overdose

If the patient does not follow medical instructions and takes an excessive dose, the drug's side effects may worsen, leading to the aforementioned symptoms. In such cases, it is important to drink more water to promote excretion. Medical treatment under a doctor’s supervision may be necessary when required.

3. Allergic Reaction

If the patient has a sensitive constitution and is allergic to any component of the drug, an allergic reaction may occur, causing symptoms such as dizziness, nausea, drowsiness, along with local rashes, itching, abdominal pain, and other discomforts. The patient should discontinue the drug promptly and, if necessary, receive treatment under a doctor’s guidance with medications such as loratadine tablets or levocetirizine hydrochloride tablets.

In addition to the common causes mentioned above, other factors such as neurasthenia, cervical spondylosis, or anemia might also contribute. Patients experiencing abnormal symptoms should seek timely medical attention to prevent worsening of the condition.
