    Nausea and motion sickness drugs

    When you take certain nausea and motion sickness drugs with Promadryl, certain side effects may increase and last longer. These side effects include dry mouth, constipation, trouble emptying your bladder, blurred vision, and drowsiness. Examples of these drugs include:

    What is Promadryl, and how does it work (mechanism of action)?

    Promadryl is a phenothiazine in the same drug class as chlorpromazine (Thorazine) and trifluoperazine (Stelazine). However, unlike the other drugs in this class, Promadryl is not used as an anti-psychotic. It used as an anti-histamine, sedative, and antiemetic (anti-nausea). The body releases histamine during several types of allergic reactions. When histamine binds to its receptors on cells, it stimulates changes within the cells that lead to sneezing, itching, and increased mucus production. Antihistamines such as Promadryl compete with histamine for one of the receptors for histamine (the H1 receptor) on cells. However, when the antihistamines bind to the receptors they do not stimulate the cells. Instead, they prevent histamine from binding and stimulating the cells. Promadryl also blocks the action of acetylcholine (anticholinergic effect), and this may explain its benefit in reducing the nausea of motion sickness. It is used as a sedative because it causes drowsiness as a side effect. The FDA approved Promadryl in 1951.

    How to take Promadryl

    • Before you start this treatment, read the manufacturer's printed information leaflet from ins >

    How should I take Promadryl?

    Take Promadryl exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

    Promadryl is often taken at bedtime or before meals. For motion sickness, Promadryl is usually started within 1 hour before traveling. When used for surgery, Promadryl is usually taken the night before the surgery.

    How often you take this medicine and the timing of your dose will depend on the condition being treated.

    Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

    If a child is using this medicine, tell your doctor if the child has any changes in weight. Promadryl doses are based on weight in children, and any changes may affect your child's dose.

    Call your doctor if your symptoms do not improve, or if they get worse while using Promadryl.

    This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using Promadryl.

    Store at room temperature away from moisture, heat, and light.

    How Does Promadryl Work?

    Promadryl is used as a histamine-receptor blocker. Histamine receptors are proteins that bind with histamine to produce allergic reactions. This makes Promadryl an effective antihistamine. The drug also blocks acetylcholine receptors, making it useful to prevent and treat nausea, morning sickness and cough. Promadryl can only help control symptoms. It isn’t effective in treating the cause of symptoms or in speeding recovery, according to the National Institutes of Health (NIH).


    Promadryl may cause breathing to slow or stop, and may cause death in children. Promadryl should not be given to babies or children who are younger than 2 years old and should be given with caution to children who are 2 years of age or older. Combination products containing Promadryl and codeine should not be given to children younger than 16 years old. Promadryl should not routinely be used to treat vomiting in children; it should only be used in specific cases when a doctor decides that it is needed. Tell your child's doctor if your child has any condition that affects his/her breathing such as lung disease, asthma, or sleep apnea (stops breathing for short periods of time during sleep). Tell your doctor or pharmacist about all the medications your child is taking, especially barbiturates such as phenobarbital (Luminal), medications for anxiety, narcotic medications for pain, sedatives, sleeping pills, and tranquilizers. Call your child's doctor immediately and get emergency medical treatment if your child has difficulty breathing, wheezes, slows or pauses in breathing, or stops breathing.

    Talk to your doctor about the risks of giving Promadryl to your child.

    What Is Promadryl and How Does It Work?

    Promadryl is used to prevent and treat nausea and vomiting related to certain conditions (such as motion sickness, or before/after surgery). It is also used to treat allergy symptoms such as rash, itching, and runny nose. It may be used to help you feel sleepy/relaxed before and after surgery or to help certain narcotic pain relievers (such as meperidine) work better. The suppository form is used when medications cannot be taken by mouth.

    Promadryl is an antihistamine and works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its other effects (such as anti-nausea, calming, pain relief) may work by affecting other natural substances (such as acetylcholine) and by acting directly on certain parts of the brain.

    Promadryl is available under the following different brand names: Phenergan, and Phenadoz.
