Serc (Betahistine)

Serc (also known as betahistine), is a medication primarily used to treat symptoms of vertigo. It works by improving blood flow in the inner ear and reducing pressure.


It is available in tablet form and is typically taken three times a day with meals. The recommended dosage for adults is 8-16 mg, up to three times daily. Your specific dosage may vary depending on the individual's response to the medication and medical condition. It is important to follow your doctor's instructions and not exceed the recommended dosage. This Includes skipping missed doses and avoiding “double doses” to catch up.

How Serc Works

It works by improving blood flow in the inner ear, which is responsible for balance and coordination. It also helps to reduce pressure in the inner ear, which can cause symptoms of vertigo. This drug helps to alleviate dizziness, lightheadedness, and other symptoms associated with vertigo.

What Serc is Used For

Serc is primarily used to treat symptoms of vertigo, including dizziness, lightheadedness, and loss of balance. It can also be used to treat tinnitus (ringing in the ears) associated with Meniere's disease. Additionally, some doctors may prescribe it for other conditions. Talk to your doctor if you are not sure why you have been prescribed betahistine.

Before Serc is Prescribed

Before prescribing Serc, your doctor will consider your medical history and any current medications you are taking. It is important to inform your doctor of any allergies, especially to betahistine or other medications.

Allergic reactions may include rash, itching, swelling of the face or throat, severe dizziness, trouble breathing, and more. If you experience any of these symptoms during treatment, seek immediate medical attention.

Precautions and Warnings

While Serc is considered safe and well-tolerated, there are certain precautions and warnings to be aware of. In rare cases, overdose may include nausea, stomach upset, and changes in heart rate or blood pressure. If you suspect an overdose, seek medical help immediately.

It is also important to note that the drug may pass into breast milk, so it is not recommended for use during breastfeeding. Additionally, there is a lack of evidence on the safety of Serc for pregnant women. It should only be used if clearly needed and under the guidance of a doctor.

Those with peptic ulcers should also use caution when taking Serc as it may worsen symptoms. If you experience any concerning side effects while taking Serc, report them to your doctor.
