Interactions between your drugs

Moderate

trichlormethiazide methyl aminolevulinate topical

Applies to: Naqua (trichlormethiazide) and Metvixia (methyl aminolevulinate topical)

MONITOR: Concomitant use of aminolevulinate topical preparations with other known photosensitizing agents may enhance the phototoxic reaction to photodynamic therapy. These agents have each been individually associated with photosensitivity reactions and may have additive effects if administered concurrently. Medicinal products with known phototoxic or photoallergic potential include fluoroquinolones, phenothiazines, retinoids, sulfonamides, sulfonylureas, tetracyclines, thiazide diuretics, griseofulvin, and hypericin extracts (e.g., St John's Wort).

MANAGEMENT: Caution is advised and pharmacologic response to photodynamic therapy should be carefully monitored if concomitant use of other photosensitizing agents cannot be avoided. Patients should be advised to avoid exposure of treated areas to sunlight or bright indoor lights (e.g., examination lamps, operating room lamps, tanning beds, lights at close proximity) during the period between application of aminolevulinic acid or methyl aminolevulinate and photoactivation, and for 48 hours post-illumination. As sunscreen is not effective in protecting treated areas of skin, patients should be counseled to wear protective apparel, such as a wide-brimmed hat, long sleeve shirt, and gloves to protect themselves. Concomitant use with other topical medicinal products should be avoided. Some authorities recommend avoiding use of hypericin-containing products for 2 weeks prior to treatment with topical aminolevulinic acid.

Drug and food interactions

Moderate

trichlormethiazide food

Applies to: Naqua (trichlormethiazide)

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
