Index Terms

  • CL-184116
  • Dihematoporphyrin Ether
  • Porfimer Sodium

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Solution Reconstituted, Intravenous, as sodium [preservative free]:

Photofrin: 75 mg (1 ea)

Brand Names: U.S.

  • Photofrin

Pharmacologic Category

  • Antineoplastic Agent, Miscellaneous


Porfimer's cytotoxic activity is dependent on light and oxygen. Following administration, the drug is selectively retained in neoplastic tissues. Exposure of the drug to laser light at wavelengths >630 nm results in the production of oxygen free-radicals. Release of thromboxane A2, leading to vascular occlusion and ischemic necrosis, may also occur.

Concerns related to adverse effects:

• Airway obstruction: Treatment-induced inflammation may obstruct airway. Use with caution in patients with endobronchial tumors, especially if in areas where main airway may be obstructed (long or surrounding tumors). Necrotic debris or mucositis may also cause airway obstruction. Monitor closely between laser therapy and debridement for respiratory distress; may require urgent bronchoscopy to remove secretions or debris.

• Chest pain: Inflammatory responses within the treatment area may result in substernal chest pain.

• Esophageal strictures: Esophageal strictures may occur, usually within 6 months of treatment. May require multiple dilations to resolve. The risk is increased with nodule pretreatment or with re-treatment of the same area.

• Extravasation: Avoid extravasation. If extravasation occurs, protect affected area from light; use of antidotes is of unknown benefit.

• Gastroesophageal fistula/perforation: Serious and potentially fatal gastrointestinal and esophageal necrosis and perforation may occur following treatment. Due to the high risk for fistula, do not use in patients with esophageal tumors eroding into the trachea or bronchial tree/wall. Use is contraindicated in patients with existing tracheoesophageal or bronchoesophageal fistula.

• Hemorrhage: Patients with esophageal varices or tumors eroding into pulmonary blood vessels are at increased risk for hemorrhage, including fatal massive pulmonary hemoptysis (FMH). Other risk factors for FMH include large, centrally-located tumors, cavitating tumors, or extensive tumor extrinsic to the bronchus.

• Ocular photosensitivity: Ocular discomfort has been reported with sun or bright light exposure. For at least 30 days (and until ocular sensitivity resolves), when outdoors, patients should wear dark sunglasses which have an average white light transmittance of <4%.

• Photosensitivity: Photosensitivity reactions are common in patients who are exposed to direct sunlight or bright indoor light (eg fluorescent lights, unshaded light bulbs, examination/operating lights). Conventional ultraviolet (UV) sunscreens are not protective against photosensitivity reactions caused by visible light. Photosensitivity may last 30 to 90 days or more. Encourage exposure to ambient indoor light (aids in gradually inactivating residual porfimer). Patients should be educated to test for residual photosensitivity before resuming exposure to sunlight. Re-exposure to general sunlight should be gradual (expose small area of skin [not the face] for 10 minutes, if no photosensitivity (eg, edema, erythema, blistering) occurs after 24 hours, may gradually resume normal outdoor activities; if photosensitivity occurs then wait 2 weeks and retest).

• Thromboembolism: Thromboembolic events may occur, generally in patients with additional risk factors for thromboembolism (eg, advanced cancer, prolonged immobilization, cardiovascular disease, or following major surgery).

Disease-related concerns:

• Barrett esophagus: In patients with Barrett esophagus, conduct rigorous surveillance (endoscopic biopsy every 3 months until 4 consecutive negative results for high-grade dysplasia followed by further follow-up per physician judgment). The long-term effects of photodynamic therapy in patients with Barrett esophagus is not known. Esophageal strictures are common adverse events associated with photodynamic therapy of Barrett esophagus; esophageal dilation may be required.

• Esophageal/gastric varices: Not suited for treatment of patients with esophageal or gastric varices (due to the high risk for hemorrhage).

• Hepatic impairment: Elimination may be prolonged in hepatic impairment; toxicities may be increased. Photosensitivity may be increased beyond 90 days in patients with mild-to-severe hepatic impairment.

• Renal impairment: Elimination may be prolonged in renal impairment; toxicities may be increased. Photosensitivity may be increased beyond 90 days in patients with severe renal impairment.

Concurrent drug therapy issues:

• Photosensitizing drugs: Concurrent use with other photosensitizing agents may increase the risk for photosensitivity reactions.

Special populations:

• Radiation therapy recipients: Allow 2 to 4 weeks to elapse after phototherapy prior to initiating radiation therapy; 4 weeks should elapse after radiation therapy prior to initiating phototherapy.

Monitoring Parameters

Monitor injection site during infusion (for extravasation); monitor in between laser and debridement for evidence of respiratory distress in patients with endobronchial tumors; monitor for signs/symptoms of photosensitivity, hemorrhage, thromboembolic events, gastroesophageal fistulas/perforation, esophageal strictures.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience hair growth, nausea, vomiting, abdominal pain, constipation, diarrhea, weight loss, lack of appetite, anxiety mouth irritation, cough, pharyngitis, skin discoloration, skin changes, insomnia, or back pain. Have patient report immediately to prescriber signs of a urinary tract infection (hematuria, burning or painful urination, polyuria, fever, lower abdominal pain, or pelvic pain), signs of dehydration (dry skin, dry mouth, dry eyes, increased thirst, tachycardia, dizziness, fast breathing, or confusion), severe headache, severe dizziness, passing out, vision changes, confusion, signs of severe cerebrovascular disease (change in strength on one side is greater than the other, difficulty speaking or thinking, change in balance, or vision changes), signs of bowel problems (black, tarry, or bloody stools; fever; mucus in stools; vomiting; vomiting blood; severe abdominal pain; constipation; or diarrhea), shortness of breath, swelling of arms or legs, excessive weight gain, chest pain, tachycardia, abnormal heartbeat, vaginitis, difficulty swallowing, persistent cough, signs of blood clots (numbness or weakness on one side of the body; pain, redness, tenderness, warmth, or swelling in the arms or legs; change in color of an arm or leg; chest pain; shortness of breath; tachycardia; or coughing up blood), severe skin reaction, or severe loss of strength and energy (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
