Medications That May Cause Jaw Pain Side Effects

Jaw pain can be an unexpected and distressing side effect of certain medications, impacting daily activities like eating, speaking, or even smiling. While not common, this side effect can stem from various drugs, ranging from painkillers to treatments for chronic conditions. In 2025, awareness of these risks is crucial for patients and healthcare providers alike. This blog explores medications, including tapentadol tablets, that may cause jaw pain, their mechanisms, management strategies, and alternative options. We’ll also cover medical treatments, pain relief approaches, and answer frequently asked questions to help you navigate this issue effectively.

Medications Linked to Jaw Pain Side Effects

Tapentadol Tablets: Opioid-Related Jaw Tension

Tapentadol (Nucynta), an opioid analgesic prescribed for moderate to severe pain, is occasionally associated with jaw pain due to muscle tension or clenching.

How It Causes Jaw Pain: Tapentadol affects the central nervous system, potentially leading to involuntary muscle contractions, including in the jaw (bruxism-like effects). This can cause temporomandibular joint (TMJ) discomfort.
Dosage: Typically 50–200 mg every 12 hours, as prescribed, not exceeding 500 mg daily.
Risk Factors: Higher doses (e.g., 200 mg), prolonged use, or pre-existing TMJ issues.
Prevalence: Rare, reported in less than 2% of users per clinical data.
Management: Dose adjustment, muscle relaxants, or switching to non-opioid painkillers.

Bisphosphonates: Risk of Osteonecrosis

Bisphosphonates, used for osteoporosis (e.g., alendronate, zoledronic acid), can rarely cause osteonecrosis of the jaw (ONJ), a serious condition involving jawbone deterioration.

How It Causes Jaw Pain: Inhibits bone remodeling, leading to poor healing after dental procedures, causing jaw pain or exposed bone.
Common Drugs: Fosamax, Boniva, Reclast.
Risk Factors: Long-term use, dental surgeries, or poor oral hygiene.
Prevalence: Affects 0.01–0.1% of users, per 2025 studies.
Management: Dental evaluation before starting treatment, pausing therapy pre-dental surgery.

Antidepressants: Bruxism and TMJ Pain

Certain antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) like sertraline or fluoxetine, may trigger jaw pain through bruxism (teeth grinding).

How It Causes Jaw Pain: Alters serotonin levels, increasing muscle activity during sleep, straining the TMJ.
Common Drugs: Prozac, Zoloft, Lexapro.
Risk Factors: High doses, anxiety disorders, or nighttime use.
Prevalence: Affects 5–10% of SSRI users, per recent reviews.
Management: Mouthguards, dose reduction, or switching to non-SSRI antidepressants.

Antipsychotics: Dystonia and Jaw Stiffness

Antipsychotics, such as risperidone or haloperidol, can cause extrapyramidal symptoms, including jaw stiffness or dystonia.

How It Causes Jaw Pain: Disrupts dopamine pathways, leading to muscle spasms in the jaw.
Common Drugs: Risperdal, Abilify, Haldol.
Risk Factors: First-generation antipsychotics, high doses, or elderly patients.
Prevalence: Occurs in 1–5% of users.
Management: Anticholinergic drugs (e.g., benztropine), dose adjustment, or alternative antipsychotics.

Chemotherapy Drugs: Mucositis and Jaw Discomfort

Certain chemotherapy agents, like methotrexate or 5-fluorouracil, can cause oral mucositis, leading to jaw pain indirectly.

How It Causes Jaw Pain: Inflames oral tissues, making chewing painful and straining the jaw.
Risk Factors: High-dose regimens or combined therapies.
Prevalence: Affects 20–40% of chemotherapy patients.
Management: Oral rinses, topical anesthetics, or painkillers.

Medical Treatments for Jaw Pain

Non-Surgical Treatments

Physical Therapy: Strengthens jaw muscles and improves TMJ function. Best for: Bruxism or tapentadol-related muscle tension. Frequency: 1–2 sessions weekly.
Mouthguards/Splints: Prevent teeth grinding from antidepressants or stress. Cost: $200–$800, per 2025 estimates.
Botox Injections: Relaxes overactive jaw muscles in severe bruxism. Frequency: Every 3–6 months. Precautions: Requires a skilled provider.
Oral Rinses: Soothe mucositis from chemotherapy. Example: Saltwater or prescription “magic mouthwash.”

Surgical Treatments

Debridement or Resection: For advanced ONJ from bisphosphonates, removes dead bone.
Recovery: 4–12 weeks.
TMJ Arthroscopy: Repairs joint damage from chronic bruxism.
Recovery: 2–6 weeks.
Dental Procedures: Extractions or implants may be needed if jaw pain stems from untreated dental issues post-medication.

Complementary Approaches

Heat/Cold Therapy: Heat relaxes jaw muscles; cold reduces inflammation. Application: 15 minutes every 2–3 hours.
Stress Management: Meditation or yoga reduces bruxism triggered by antidepressants or stress.
Dietary Adjustments: Soft foods minimize jaw strain during mucositis or ONJ recovery.

Painkillers for Managing Jaw Pain

Over-the-Counter Options

Ibuprofen (Advil): Reduces inflammation and pain in TMJ or muscle-related jaw pain. Dosage: 200–400 mg every 4–6 hours, max 3,200 mg daily. Precautions: Avoid long-term use to prevent gastrointestinal issues.
Acetaminophen (Tylenol): Eases pain without anti-inflammatory effects. Dosage: 500–1,000 mg every 4–6 hours, max 4,000 mg daily. Precautions: Monitor for liver risks with overuse.
Benzocaine Gels (Orajel): Numbs localized pain in the oral cavity. Dosage: Apply a small amount up to 4 times daily. Precautions: Not for children under 2 due to methemoglobinemia risk.

Prescription Painkillers

Tapentadol (Alternative Use): While tapentadol may cause jaw pain in rare cases, it can also be prescribed for severe jaw pain from other causes (e.g., post-dental surgery). Dosage: 50–100 mg every 12 hours, as needed. Precautions: Monitor for worsening jaw tension or addiction risk.
Tramadol: A milder opioid for moderate jaw pain. Dosage: 50–100 mg every 4–6 hours, max 400 mg daily. Precautions: Risk of dependence.
Muscle Relaxants (e.g., Cyclobenzaprine): Relieves jaw muscle spasms from bruxism or dystonia. Dosage: 5–10 mg 2–3 times daily. Precautions: Causes drowsiness.

Prescription Medications for Underlying Causes

Anticholinergics (e.g., Benztropine): Treat antipsychotic-induced jaw dystonia. Dosage: 1–2 mg daily, adjusted by a doctor.
Buspirone: May reduce SSRI-induced bruxism in some patients. Dosage: 5–10 mg 2–3 times daily.
Antibiotics or Antifungals: For ONJ-related infections from bisphosphonates. Example: Amoxicillin or nystatin, as prescribed.
Topical Corticosteroids: For chemotherapy-induced mucositis. Example: Dexamethasone oral rinse.
