Safety and Efficiency of Seysara (Sarecycline) for Acne in Teenagers
Seysara (sarecycline) is a safe and effective FDA-approved treatment option for moderate to severe acne in teenagers aged 9 years and older, with a narrow antibacterial spectrum that offers advantages over older tetracyclines by causing less disruption to gut microbiome and lower rates of side effects. 1, 2
Efficacy Profile
- Sarecycline is specifically designed for treating inflammatory acne with demonstrated efficacy in reducing inflammatory lesions by approximately 50% after 12 weeks of treatment at the recommended dose of 1.5 mg/kg/day 3, 4
- Clinical improvement can be observed as early as 3 weeks after starting treatment, making it an effective option for teenagers seeking relatively quick results 4
- Sarecycline is included in the American Academy of Dermatology guidelines as a conditionally recommended systemic antibiotic option for moderate to severe acne in adolescents and preadolescents (≥9 years) 5
- It is particularly effective for inflammatory acne lesions on both the face and trunk (chest and back), which is notable as many acne studies focus only on facial acne 6
Safety Profile
- Sarecycline has a narrow spectrum of antibacterial activity primarily targeting Cutibacterium acnes (formerly Propionibacterium acnes), with minimal activity against enteric Gram-negative bacteria 2, 6
- This narrow-spectrum activity leads to fewer gastrointestinal side effects compared to older tetracyclines, with similar gastrointestinal adverse event rates to placebo in clinical trials 3, 4
- Common side effects include nausea (4.6%), nasopharyngitis (2.5-3.1%), and headache (2.7-2.9%), with most not considered treatment-related 4
- Notably low rates of side effects commonly associated with tetracyclines:
Dosing and Administration
- Sarecycline is administered once daily at a dose of 1.5 mg/kg/day with or without food 1, 3
- Available in tablet form in various strengths (60 mg, 100 mg, 150 mg) to accommodate weight-based dosing 1
- Should be taken with enough fluid to completely swallow the tablet and reduce risk of esophageal irritation 1
Contraindications and Precautions
- Contraindicated in patients with hypersensitivity to tetracycline-class antibiotics 1
- Should not be used during pregnancy as it may harm the unborn baby 1
- Not recommended during breastfeeding 1
- Like other tetracyclines, should not be used in children under 8 years of age due to risk of permanent teeth discoloration during tooth development 1
- May cause photosensitivity; patients should minimize sun exposure and use sunscreen 1
Treatment Algorithm for Teenagers with Acne
- For mild acne: Start with topical therapy (benzoyl peroxide and/or topical retinoid) 7
- For moderate acne: Use combination topical therapy (benzoyl peroxide + topical retinoid or benzoyl peroxide + topical antibiotic) 7
- For moderate to severe acne with inadequate response to topical therapy after 6-8 weeks: Add oral antibiotic therapy, with sarecycline being a good option for teenagers ≥9 years old 5, 7
- For severe acne with scarring or significant psychosocial impact: Consider isotretinoin 5, 8
Important Considerations and Pitfalls to Avoid
- Sarecycline should not be used as monotherapy; always combine with topical treatments to enhance efficacy and prevent bacterial resistance 5, 7
- Limit systemic antibiotic use to the shortest possible duration (ideally ≤3 months) to minimize risk of bacterial resistance 5
- Monitor for rare but serious side effects such as intracranial hypertension (symptoms include headache, blurred vision) 1
- Consider the psychological impact of acne when determining treatment aggressiveness, as acne can significantly affect quality of life in teenagers 8
- Advise patients to drink plenty of fluids when taking sarecycline to reduce the risk of esophageal irritation 1
In conclusion, Seysara (sarecycline) represents an effective and well-tolerated treatment option for moderate to severe acne in teenagers aged 9 years and older, with advantages over older tetracyclines due to its narrow spectrum of activity and favorable side effect profile.
