Protect From Light
Introduction
Light exposure causes photodegradation, which destroys some drugs, and in some cases, increases a drug's toxicity (e.g. nitroprusside).
Many medications should be protected from light during storage to avoid degradation.
- Some medications are supplied in amber (light-protected) vials, while others are stored in the original packaging (foil overwrap or box) until needed.
Protect During Administration
A small number of drugs are so light-sensitive that they require protection from light during administration.
- In some cases, pharmacy staff dispense these medications with a light-protective tubing (generally amber-coloured).
Examples
- Amphotericin B
- Doxorubicin
- Doxycycline
- Pegfilgrastim and biosimilars
- Phytonadione
- Selexipag
- Sodium nitroprusside
- Thiotepa - subject to manufacturer
