ED A-Hist DM should be used exactly as directed on the product label.

• Dosage: The dosage varies by age and the specific product (tablet vs. liquid). Always use the provided measuring device for the liquid form to ensure accuracy.
• Frequency: It is typically taken every 4 hours as needed for symptom relief. Do not exceed the recommended dose in a 24-hour period.
• Short-Term Use: This medication is for short-term use to relieve cold and allergy symptoms. If your symptoms do not improve within one week, or if they worsen or are accompanied by a fever, rash, or persistent headache, you should stop using the medication and consult a doctor.
• Children: Do not give this medication to children under 6 years of age without a doctor’s recommendation.

The three active ingredients work together to provide multi-symptom relief:

• Chlorpheniramine is a first-generation antihistamine. It works by blocking the effects of histamine, a substance the body releases during an allergic reaction, which causes symptoms like sneezing, itching, and a runny nose.
• Dextromethorphan works on the cough center in the brain (the medulla oblongata) to suppress the cough reflex.
• Phenylephrine is a vasoconstrictor. It works by narrowing the blood vessels in the nasal passages, which reduces swelling and congestion, making it easier to breathe through the nose.

Side effects of ED A-Hist DM can range from common to more serious.

• Common Side Effects: Drowsiness, dizziness, dry mouth, headache, upset stomach, and nervousness.
• Serious Side Effects: Increased heart rate, palpitations, high blood pressure, confusion, hallucinations, or difficulty urinating (especially in men with an enlarged prostate). Children may experience excitability or agitation.
• Allergic Reactions: Seek immediate medical attention if you experience signs of an allergic reaction, such as hives, rash, swelling, or difficulty breathing.

• Do Not Use If: You have a history of a chronic cough with a lot of phlegm, breathing problems (like emphysema or chronic bronchitis), glaucoma, heart disease, high blood pressure, thyroid disease, or diabetes.
• Operating Machinery: This medication can cause drowsiness and dizziness. You should avoid driving, operating machinery, or performing tasks that require alertness until you know how the medication affects you.
• Pregnancy and Breastfeeding: Consult with a healthcare professional before using this product if you are pregnant or breastfeeding.

ED A-Hist DM can have several important drug interactions. It is crucial to inform your doctor or pharmacist about all medications, vitamins, and supplements you are taking.

• MAO Inhibitors: Do not use this medication if you are currently taking or have stopped taking an MAO inhibitor (e.g., isocarboxazid, linezolid, methylene blue) within the last 14 days. This combination can lead to a dangerous increase in blood pressure.
• CNS Depressants: The antihistamine and cough suppressant in ED A-Hist DM can cause drowsiness. Combining it with alcohol, sedatives, tranquilizers, opioids, or other drugs that cause drowsiness can increase the risk of severe sedation, dizziness, and respiratory depression.
• Other Stimulants/Decongestants: Do not take other medications that contain decongestants or stimulants without consulting a doctor, as this can increase the risk of side effects like increased heart rate and high blood pressure.
• Medications for High Blood Pressure: The phenylephrine in this product can increase blood pressure and may interfere with the effectiveness of certain blood pressure medications.

• Adults and Children 12 years and older: Typically 1 tablet or 5 mL of liquid every 4 hours. Do not exceed 6 doses in 24 hours.
• Children 6 to under 12 years: Typically 1/2 tablet or 2.5 mL of liquid every 4 hours. Do not exceed 3 to 6 doses in 24 hours, depending on the specific product instructions.
• Children under 6 years: Consult a doctor.
