Large doses and parenteral administration should be used cautiously, or avoided, in patients with impaired cardiovascular systems.
Asthma
Moderate:
Promethazine DM
The promethazine in Promethazine DM has a moderate potential interaction with Asthma.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Bone Marrow Depression/Low Blood Counts
Major:

Diabetes Mellitus
Moderate:

Gastrointestinal Obstruction
Moderate:
Promethazine DM
The promethazine in Promethazine DM has a moderate potential interaction with Gastrointestinal Obstruction.

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.
