Systemic adverse effects of topical ocular treatments
- Some eyedrops, gels or ointments may cause adverse effects as serious as those observed with systemic therapies.
- Because of their relatively poor penetration into eye tissue, ophthalmic drugs usually contain high concentrations of their active ingredient.
- Asking patients about these drugs to prevent interactions is useful when prescribing a new systemic treatment.
- Conversely, it is advisable to ask about ophthalmic drugs during the etiological investigation of possible iatrogenic effects.
