Doxytex liquid

Generic Name: doxylamine (dox-IL-a-meen)
Brand Name: Doxytex

Doxytex liquid is used for:

Treating symptoms of allergies, such as runny nose, sneezing, nose or throat itching, or itchy, watery eyes. It may also be used for other conditions as determined by your doctor.

Doxytex liquid is an antihistamine. It works by blocking the action of histamine, which reduces the symptoms of an allergic reaction. It also depresses the central nervous system (brain) to produce drowsiness.

Do NOT use Doxytex liquid if:

  • you are allergic to any ingredient in Doxytex liquid or to any other similar medicine
  • you are taking sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) in the past 2 weeks
  • you are breast-feeding

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

Before using Doxytex liquid:

Some medical conditions may interact with Doxytex liquid. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, emphysema, lung disease, shortness of breath, or sleep apnea
  • if you have blockage of the stomach, intestine, or urinary tract; difficulty urinating; or a history of diabetes, ulcers, enlargement of the prostate, glaucoma, heart disease, high blood pressure, the blood disease porphyria, seizures, stroke, or thyroid disease

Some MEDICINES MAY INTERACT with Doxytex liquid. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Sodium oxybate (GHB) because an increase in sleep duration and a decrease in the ability to breathe are likely to occur
  • Furazolidone or MAOIs (eg, phenelzine) because serious side effects, such as high blood pressure and seizures, may occur

This may not be a complete list of all interactions that may occur. Ask your health care provider if Doxytex liquid may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
