Summary
Porfimer photodynamic therapy relies on light-activated photosensitizer, and drugs that inhibit platelet aggregation or thrombosis could theoretically reduce its effect. Labeling notes this possibility for anticoagulants. Clinical significance is uncertain.
What this interaction means in plain words
Dalteparin and Porfimer can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dalteparin belongs to Cardiovascular; Porfimer belongs to Miscellaneous.
Why it happens
Photodynamic injury partly depends on thromboxane-mediated vascular occlusion, which anticoagulants might diminish.
What to do
Consider timing of dalteparin around photodynamic therapy and assess treatment response. Weigh thrombosis risk before interrupting anticoagulation.
What to ask your pharmacist
