DryMax syrup

Generic Name: chlorpheniramine/pseudoephedrine/methscopolamine (KLOR-fen-IR-a-meen/SOO-doe-e-FED-rin/METH-skoe-POL-a-meen)
Brand Name: DryMax

DryMax syrup is used for:

Relieving congestion, sneezing, runny nose, and itchy, watery eyes due to colds, flu, or hay fever. It may also be used for other conditions as determined by your doctor.

DryMax syrup is an antihistamine, decongestant, and anticholinergic combination. The antihistamine works by blocking histamine, a substance in the body that causes sneezing, runny nose, and watery eyes. The decongestant relieves nasal congestion by shrinking the nasal mucous membranes, which promotes nasal drainage. The anticholinergic dries the chest by decreasing lung secretions.

Do NOT use DryMax syrup if:

  • you are allergic to any ingredient in DryMax syrup
  • you are pregnant or breast-feeding
  • you take droxidopa or sodium oxybate (GHB), or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the last 14 days
  • you have severe high blood pressure, severe heart blood vessel disease, rapid heartbeat, severe heart problems, or narrow-angle glaucoma
  • you have severe or uncontrolled bleeding; a blockage of your bladder, stomach, or bowel; muscle weakness (eg, myasthenia gravis); stomach ulcer; severe bowel problems (eg, ulcerative colitis, toxic megacolon); inflammation of the esophagus from reflux disease; or trouble swallowing
  • you are unable to urinate or are having an asthma attack

Contact your doctor or health care provider right away if any of these apply to you.
