Diabetes Mellitus
Moderate:
DM-PE-Chlor
The phenylephrine in DM-PE-Chlor has a moderate potential interaction with Diabetes Mellitus.
Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.
Esophagitis
Major:
house dust mite allergen extract
House dust mite allergen extract has a major potential interaction with Esophagitis.
The use of allergen immunotherapy, such as mixed grass pollens, ragweed pollen, house dust mite allergen extract, and timothy grass pollen allergen extracts, is contraindicated in patients with a history of eosinophilic esophagitis. This condition could compromise swallowing, lead to food impaction, vomiting, and heartburn which may cause permanent damage to the esophagus.
Gastrointestinal Obstruction
Moderate:
DM-PE-Chlor
The chlorpheniramine in DM-PE-Chlor has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Glaucoma/Intraocular Hypertension
Moderate:
DM-PE-Chlor
The phenylephrine in DM-PE-Chlor has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors.
