Are pregnant or breastfeeding (safety data are limited; discuss alternatives with your provider).
Are under 18 years of age.
Have a known allergy to copper, peptides, or any ingredient in your prescription.
Have Wilson disease or another condition that causes copper to build up in the body. People with Wilson disease should avoid supplements containing copper.
Are taking copper‑removing (chelating) medications such as penicillamine or trientine, unless your prescribing clinician specifically directs otherwise.
A history of liver disease, abnormal liver tests, or known elevated copper levels, since excess copper exposure over time can contribute to liver injury in susceptible individuals.
Any chronic medical condition or you’re taking multiple prescriptions/supplements (so your clinician can check fit and interactions).
Always tell your provider about all medications and supplements, especially:
Copper chelators (used for copper overload):
Penicillamine can increase copper excretion; guidance commonly recommends avoiding copper‑containing supplements during therapy.
Trientine binds excess copper and may reduce copper absorption; combining with copper products should be clinician‑directed.
Certain antibiotics (fluoroquinolones/tetracyclines): copper‑containing products can reduce absorption of some antibiotics through mineral binding. If you’re prescribed antibiotics like ciprofloxacin (or similar), your clinician may recommend separating doses by several hours.
High‑dose zinc supplements: high zinc intake can reduce copper absorption and shift copper status over time.
Side effects vary by person and formulation. Commonly reported effects may include:
Mild stomach upset, nausea, abdominal discomfort, diarrhea
Headache
Metallic taste
Mild rash or skin sensitivity
Stop the medication and contact your provider promptly if you develop:
Persistent vomiting or severe abdominal pain
Yellowing of the skin/eyes (jaundice), dark urine, or unusual fatigue (possible liver stress)
New or worsening neurologic symptoms
Excess copper exposure can cause gastrointestinal symptoms (nausea, vomiting, abdominal pain, diarrhea) and—at higher or prolonged exposures—more serious injury.
Trouble breathing, swelling of the face/lips/tongue, or widespread hives (possible severe allergic reaction)
Chest pain, severe dizziness/fainting, or other severe symptoms
Take exactly as prescribed by your provider. Do not exceed the prescribed amount.
