Provider Briefing: The Clindamycin Shortage in 2026

Clindamycin remains one of the most prescribed antibiotics in the United States — and one of the most affected by chronic drug shortages. As a prescriber, understanding the current supply landscape is essential for managing patient expectations, selecting alternatives when needed, and ensuring continuity of care.

This briefing covers the current status of the Cleocin (Clindamycin) shortage, its prescribing implications, available alternatives, and tools to help your patients access their medications.

Shortage Timeline

The Clindamycin shortage — particularly for injectable formulations — is one of the longest-running drug shortages in the U.S.:

  • June 2015: Clindamycin phosphate injection first appears on the ASHP drug shortage list
  • 2015-2023: Chronic shortage status with multiple manufacturers reporting back orders and production delays. As of April 2023, ASHP reported insufficient supply for 21 Clindamycin injection products.
  • 2024-2025: Pfizer reports Cleocin Phosphate 150 mg/mL 4 mL vials on back order with an estimated release of December 2025. Sagent reports 60 mL vials on back order with no estimated release date.
  • 2026: Injectable shortage persists. Oral capsules generally available through generic manufacturers. Topical forms in relatively stable supply with new generic approvals (including a Glenmark Clindamycin phosphate gel approved by FDA).

Prescribing Implications

The shortage has several direct implications for clinical practice:

Inpatient and Surgical Settings

The injectable shortage most directly affects hospital pharmacies, surgical centers, and infusion clinics. Institutions may face allocation limits from their group purchasing organizations (GPOs) and distributors. Pharmacy and therapeutics (P&T) committees should have contingency protocols in place, including:

  • Prioritization criteria for Clindamycin injection allocation
  • Automatic therapeutic substitution protocols
  • Communication templates for prescribers when Clindamycin injection is unavailable

Outpatient Prescribing

For outpatient prescribing, oral Clindamycin capsules are generally available from multiple generic manufacturers (including Greenstone/Pfizer, Amneal, Alembic, and others). However, individual pharmacies may experience temporary stock-outs due to:

  • Distributor allocation limits
  • Regional demand spikes
  • Specific strength or NDC unavailability

Consider writing prescriptions with "dispense as written" flexibility to allow pharmacists to fill with any available manufacturer.

Penicillin-Allergic Patients

Clindamycin is frequently the first-line alternative for penicillin-allergic patients, particularly for dental prophylaxis and skin/soft tissue infections. The shortage makes it especially important to:

  • Verify the nature of the penicillin allergy (true IgE-mediated vs. intolerance)
  • Consider penicillin allergy testing and delabeling where appropriate
  • Have alternative protocols ready for endocarditis prophylaxis and surgical prophylaxis

Current Availability Picture

FormulationStatusNotes
Injectable (Clindamycin phosphate)ShortageOn ASHP list since 2015. Multiple manufacturers on back order.
Oral capsules (75 mg, 150 mg, 300 mg)Generally availableMultiple generic manufacturers. Sporadic pharmacy-level stock-outs.
Oral solution (75 mg/5 mL)Generally availableUseful alternative when capsules unavailable.
Topical gel/lotion/solution (1%)AvailableNew generic approval from Glenmark adds supply.
Vaginal cream/suppositoriesAvailableStable supply from multiple manufacturers.

Cost and Access Considerations

Cost can be a barrier to access for uninsured or underinsured patients:

  • Brand-name Cleocin capsules: ~$411 for 30 capsules (300 mg)
  • Generic Clindamycin capsules: ~$106 retail, but $15-$50 with discount cards (GoodRx, SingleCare, Optum Perks)
  • Insurance coverage: Generic Clindamycin is Tier 1 on most formularies. Prior authorization is typically not required for oral forms.
  • Patient assistance: Pfizer RxPathways may cover eligible patients. NeedyMeds and RxAssist list additional programs.

Tools and Resources for Your Practice

Medfinder for Providers

Medfinder offers real-time pharmacy inventory search that your staff can use to help patients locate Clindamycin in stock near them. Instead of asking patients to call pharmacy after pharmacy, you can search stock from your office and direct patients to specific pharmacies with confirmed availability.

Alternative Antibiotics Quick Reference

When Clindamycin is unavailable, consider these alternatives based on clinical indication:

  • Skin/soft tissue (including MRSA): Doxycycline, Trimethoprim-Sulfamethoxazole (Bactrim)
  • Dental/endocarditis prophylaxis: Azithromycin 500 mg single dose, Cephalexin 2g (if no true penicillin allergy)
  • Intra-abdominal infections: Metronidazole (often combined with a fluoroquinolone or cephalosporin)
  • Gynecological infections: Metronidazole (vaginal or oral)
  • Bone and joint: Vancomycin (IV), Doxycycline, or Linezolid depending on culture and sensitivity

ASHP Drug Shortage Resources

Monitor the ASHP Drug Shortage Resource Center for real-time updates on Clindamycin availability, manufacturer communications, and alternative therapy recommendations.

Looking Ahead

The Clindamycin injection shortage shows no signs of near-term resolution. The fundamental drivers — limited sterile manufacturing capacity, thin profit margins for generics, and supply chain consolidation — are structural issues that require systemic solutions.

Oral and topical forms are in better shape, with new generic entrants adding manufacturing capacity. The broadening of telehealth has also improved patient access to prescriptions, reducing barriers for patients in underserved areas.

As a provider, the most impactful steps you can take are:

  1. Maintain updated substitution protocols for when Clindamycin is unavailable
  2. Proactively discuss availability with patients when writing Clindamycin prescriptions
  3. Direct patients to Medfinder or assist them in locating stock
  4. Advocate for penicillin allergy testing to reduce unnecessary Clindamycin dependence
  5. Stay current on shortage updates via ASHP and FDA communications

Final Thoughts

The Clindamycin shortage is a complex, multi-year challenge that directly impacts patient care across nearly every specialty. By staying informed, maintaining flexible prescribing practices, and leveraging tools like Medfinder, providers can help ensure their patients continue to receive effective antibiotic therapy even when first-line options are constrained.

Which Clindamycin formulations are currently in shortage?

As of 2026, Clindamycin phosphate injection remains in chronic shortage and has been on the ASHP drug shortage list since June 2015. Oral capsules, oral solution, and topical/vaginal forms are generally available from multiple generic manufacturers, though individual pharmacies may experience intermittent stock-outs.

What are the recommended antibiotic substitutions when Clindamycin is unavailable?

Substitutions depend on the clinical indication. For skin/soft tissue infections (including MRSA): Doxycycline or TMP-SMX. For dental/endocarditis prophylaxis: Azithromycin 500 mg or Cephalexin 2g (if no true penicillin allergy). For anaerobic infections: Metronidazole. For bone/joint infections: Vancomycin IV or Linezolid based on culture sensitivity.

How can I help patients find Clindamycin in stock?

Use Medfinder (medfinder.com/providers) to search real-time pharmacy inventory and direct patients to specific pharmacies with confirmed stock. Also consider writing prescriptions with manufacturer flexibility, suggesting independent pharmacies, and recommending discount cards like GoodRx or SingleCare to reduce cost barriers.

Should I consider penicillin allergy delabeling to reduce Clindamycin dependence?

Yes. Studies show that up to 90% of patients labeled as penicillin-allergic can safely tolerate penicillin after formal testing. Penicillin allergy delabeling can significantly reduce Clindamycin prescribing, which helps with both shortage management and antibiotic stewardship (Clindamycin carries a higher risk of C. difficile compared to penicillin-class antibiotics).
