Capmist DM is an over-the-counter drug with two active ingredients for relief of symptoms associated with such conditions as nasal congestion, cough, and sneezing. This drug is commonly used to treat upper respiratory tract infections, seasonal allergies, and the common cold.
Capmist DM is sold under a variety of brand names and comes in several preparations, including liquid and tablet forms. Two active ingredients of Capmist DM are Diphenhydramine, which is an antihistamine, and Phenylephrine, which is a decongestant.
The suggested dosage of Capmist DM is different based on the preparation form, which can either be in tablet or liquid, and the age of the patient. Dosage instructions should always be followed from the package insert or your doctor. Here are some general guidelines on dosing:
Adults and Children 12 Years and Older:
Liquid Formulation: The usual dose for adults is 10-20 mL every 4-6 hours. The maximum amount per day is 120 mL.
Tablet Formulation: Typical dose for adults 1-2 tablets every 4-6 hours as required and the maximum daily dosage does not exceed 8 tablets.
Children (6-12 years):
Liquid Formulation: Typically 5-10 mL every 4-6 hours, with the total daily dosage not exceeding 60 mL.
Tablet Formulation: Typically 1 tablet every 4-6 hours as required, maximum daily dosage does not exceed 4 tablets
Under 6 Years :
Capmist DM should not be used for children under 6 years without the recommendation of a physician, in case of risks that side effects may occur.
Important Notes:
Use a measuring spoon or other appropriate device to measure the liquid.
Never use a dose higher than recommended daily. Consult your physician before administering this drug to a child.
If symptoms persist for more than 7 days, or if new symptoms occur such as fever or rash, consult a healthcare provider.
Diphenhydramine: As an antihistamine, Diphenhydramine works by blocking histamine receptors in the body. Histamine is responsible for many allergic symptoms, such as itching, swelling, and increased mucus production. It also helps suppress the cough reflex, making it effective for soothing dry, persistent coughs.
Phenylephrine: It acts as a decongestant. The working of this medication is on the constriction of the blood vessels of the nasal passages. With reduced blood flow, swelling and congestion in the nasal passages decrease, relieving blocked nasal airways for easier breathing.
Like every other drug, Capmist DM causes side effects, but not everyone experiences them. Common and serious side effects include:
Drowsiness: Since the drug Diphenhydramine is a sedating antihistamine, it can cause drowsiness or sleepiness. This can be helpful in those who need relief at night, but it can also present a problem if driving or operating machinery.
Dizziness: Some people may become dizzy or lightheaded after taking Capmist DM.
Dry Mouth or Throat: Antihistamines such as Diphenhydramine can lead to dryness in the mouth and throat.
Nausea or Vomiting: A few users may experience mild gastrointestinal upset.
Severe Side Effects:
Tachycardia: As a decongestant, phenylephrine may lead to a rapid or irregular heartbeat in some patients, especially when taken in excess.
Hypertension: Decongestants can elevate blood pressure. Therefore, patients with hypertension should be careful.
Before using Capmist DM, note the following:
Pre-existing medical conditions. Consult your physician if you have one or more of the following conditions:
High blood pressure, because Phenylephrine tends to increase blood pressure
Any heart disease, since the use of Phenylephrine can cause tachycardia and can precipitate arrhythmias.
Glaucoma, as it may worsen by an antihistamine.
Urinary retention or prostate problems, because diphenhydramine can exacerbate urinary retention.
Pregnancy and Breastfeeding: You should consult a doctor prior to its administration if you are pregnant or breastfeeding. Both Diphenhydramine and Phenylephrine may pass through breast milk, and therefore, their safety during the pregnancy period is not adequately established.
Alcohol: Alcohol intake should be avoided during treatment with Capmist DM because alcohol can intensify the sedative action of Diphenhydramine and increase the chances of drowsiness, dizziness, or other side effects.
Driving and Operating Machinery: Due to the risk of drowsiness, patients are advised not to drive or operate heavy machinery for a few hours after taking the medication.
Capmist DM, a combination cough and cold medication, can interact with other drugs, affecting safety and effectiveness.
Capmist DM should be taken strictly on the dosages indicated on the packaging or as a health professional prescribes. Taking more than the maximum daily dose will result in side effects, including drowsiness or even cardiovascular problems. For symptoms that do not improve, see a doctor for additional prescription or alternative treatments.
