Safety, interactions, and handling
Drug interactions: Before dispatch, our clinical team reviews every patient's full medication list against published FDA drug-interaction data. If a significant interaction is identified, we notify the prescribing physician and hold shipment until an alternative dose or timing is confirmed.
Contraindications: This medication is not appropriate for every patient. Refer to the US FDA label for full contraindication list. Patients with active infection, pregnancy, known hypersensitivity, or specific organ-system comorbidities may be excluded. Prescribing-physician judgement applies.
Cold chain and storage: Biologics, monoclonals, and cell/gene therapies require validated cold-chain shipping (2-8°C) with continuous temperature monitoring. On arrival we document temperature logs; out-of-spec shipments are flagged and replaced.
Adverse event reporting: Any adverse event should be reported to both the local national regulator and to Reserve Meds's pharmacovigilance team at pv@reservemeds.com. We forward serious events to the US manufacturer within 15 days per ICH E2D guidance.
