Cevimeline: Uses, Dosage, Side Effects and More

Introduction: What is Cevimeline?

Cevimeline is a prescription medication primarily used to treat dry mouth (xerostomia) resulting from Sjögren's syndrome, an autoimmune disorder that affects the glands that produce saliva and tears. By stimulating saliva production, Cevimeline helps alleviate the discomfort associated with dry mouth, improving the quality of life for those affected by this condition.

Uses of Cevimeline

Cevimeline is approved for the following medical uses:

1. Sjögren's Syndrome: The primary indication for Cevimeline is to treat dry mouth in patients diagnosed with Sjögren's syndrome. This condition can lead to significant discomfort and complications, including difficulty swallowing, speaking, and increased dental issues.
2. Radiation-Induced Xerostomia: Cevimeline may also be used off-label to manage dry mouth resulting from radiation therapy for head and neck cancers, although this use is less common.

How It Works

Cevimeline works by mimicking the action of acetylcholine, a neurotransmitter that stimulates the salivary glands. When taken, Cevimeline binds to specific receptors in the salivary glands, promoting saliva production. This mechanism helps to relieve the symptoms of dry mouth, making it easier for patients to eat, speak, and maintain oral hygiene.

Dosage and Administration

The standard dosage for adults is typically 30 mg taken three times a day. Cevimeline is available in tablet form and should be taken with or without food. For pediatric patients, the dosage may vary based on the child's weight and the physician's discretion. It is essential to follow the prescribing physician's instructions regarding dosage and frequency to ensure safety and effectiveness.

Drug Interactions

Cevimeline may interact with several medications, including:

• Anticholinergic drugs: These can counteract the effects of Cevimeline, reducing its efficacy.
