Drug Interactions between methyl aminolevulinate topical and moxifloxacin / triamcinolone

Moxifloxacin and other medications in its class can cause tendinitis and tendon rupture, and the risk may be increased when combined with a steroid such as triamcinolone. Older adults over 60 years of age and those who have received a kidney, heart, and/or lung transplant may be particularly susceptible. Tendon rupture can occur during or up to several months after finishing moxifloxacin treatment and may require surgery or result in prolonged disability. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Stop taking moxifloxacin and call your doctor immediately if you experience pain, swelling, or inflammation of a tendon area such as the back of the ankle, shoulder, biceps, hand, or thumb. You should also avoid exercise or use of the affected area until further instruction from your doctor. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Methyl aminolevulinate topical causes your skin to be more sensitive to light in areas where it has been applied. The risk and/or severity of reactions such as redness, scaling, swelling, stinging, and burning may be increased when it is used with other drugs that can also increase sensitivity to light such as moxifloxacin. You should avoid exposure to sunlight or bright indoor lights (examination lamps, operating room lamps, tanning beds, lights at close proximity) during and for 48 hours after treatment as directed by your doctor. Since sunscreens will not protect you against photosensitivity reactions associated with methyl aminolevulinate topical, you should protect treated areas by wearing a wide-brimmed hat or other protective apparel if exposure to sunlight or other intense lights cannot be avoided. Be advised to reduce your light exposure if you experience sensations of stinging and/or burning. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
