Med of the Month: Cevimeline

For many patients, dry mouth is more than just a nuisance, it is a daily struggle that affects eating, speaking, sleep, and overall oral health. During Sjögren’s Awareness Month, we’re highlighting a medication designed to address one of the condition’s most persistent and impactful symptoms: cevimeline.

Unlike saliva substitutes that offer temporary relief, cevimeline works by stimulating the body’s own salivary glands. For dental providers, understanding how this medication works, along with its side effects and clinical considerations, can make a meaningful difference in how we manage patients with chronic xerostomia.

Generic Name: Cevimeline 

Brand Name(s): Evoxac

Pronunciation: se vi ME leen

About this drug:

• Cevimeline is a cholinergic agonist that binds to muscarinic receptors. At therapeutic doses, it increases secretion from exocrine glands, including salivary and sweat glands, and can also increase smooth muscle tone in the gastrointestinal and urinary tracts.

• It is primarily used to treat dry mouth (xerostomia) in patients with Sjögren’s syndrome. 

Dentistry-related tidbits:

• If treating a patient taking cevimeline:

  • There are no known restrictions with local anesthetics; however, monitor blood pressure and pulse before administering epinephrine, as cevimeline may affect blood pressure.

  • Cevimeline may cause increased sweating (hyperhidrosis) and excess salivation (sialorrhea).

  • Oral side effects may include gingivitis, glossitis, and, in some cases, toothache.

  • Common systemic side effects include sweating, nausea, headache, rhinitis, and sinusitis.

• If prescribing cevimeline:

  • Note that this medication is not approved for use in patients younger than 18 years old.

  • Counsel patients that cevimeline may increase sweating. Advise them to stay well hydrated, especially during hot weather or exercise, unless otherwise directed.

  • Do not use cevimeline in patients with uncontrolled asthma, drug hypersensitivity, or eye conditions where pupil constriction is unsafe (e.g., acute iritis or narrow-angle glaucoma).

Staying Safe: important interactions to be aware of

• Using a tool like MedAssent DDS Rx Check can help support safe prescribing. Important interactions include:

  • Muscle relaxants such as cyclobenzaprine or orphenadrine may reduce the efficacy of cevimeline.

Fun facts:

• Compared to pilocarpine, another medication used for dry mouth, cevimeline tends to last longer. Pilocarpine’s effects typically wear off after about 3 hours, while cevimeline (30 mg, taken three times daily) has a longer half-life of around 5 hours, helping maintain salivary flow for a greater portion of the day.

• Sjögren's is often thought of as a rare disease, however it is estimated that there are four million Americans living with this disease, making it one of the most prevalent autoimmune diseases.

• Cevimeline doesn’t replace saliva; rather, it helps patients produce their own, which is why it can feel more “natural” than saliva substitutes.
