• Syrup: Measure the prescribed dose using the provided measuring cup or spoon. For adults, this is typically 10 mL every 4-6 hours, up to 4 doses per day.
• Tablets: Take 1 tablet with a glass of water every 4-6 hours, up to 6 tablets per day. Do not exceed the recommended dose.

Important Tips:

• Do not exceed the recommended dose. Taking more than the prescribed amount can increase the risk of serious side effects, such as excessive drowsiness, dizziness, and a potentially dangerous increase in blood pressure.
• If you miss a dose, take it as soon as you remember, unless it’s almost time for the next dose. In that case, skip the missed dose and continue with your regular dosing schedule.
• Avoid alcohol while taking this medication, as it can worsen the sedative effects and lead to dangerous side effects.
• If using the medication for more than a few days, or if symptoms worsen, contact a healthcare provider for further guidance.

• Chlorpheniramine: Chlorpheniramine blocks the effects of histamine, a chemical produced by the body during allergic reactions. Histamine binds to specific receptors in the body, causing inflammation and symptoms like sneezing, runny nose, and itchy eyes. By blocking histamine from binding to these receptors, chlorpheniramine reduces these symptoms and provides relief.
• Dextromethorphan: Dextromethorphan works in the brain by inhibiting the cough reflex, which helps reduce the urge to cough. Unlike other treatments that target the mucus or airways directly, dextromethorphan acts centrally in the nervous system to stop the cough reflex from being triggered.
• Pseudoephedrine: Pseudoephedrine works by constricting the blood vessels in the nasal passages. This action reduces the swelling of the nasal tissues, allowing the airways to open up and reducing nasal congestion. The result is easier breathing and a reduction in sinus pressure and stuffiness.

Together, these three active ingredients work synergistically to treat multiple symptoms of respiratory infections and allergies, including congestion, sneezing, coughing, and runny nose.

While Chlorpheniramine, Dextromethorphan, and Pseudoephedrine is generally safe when used as directed, it may cause side effects. Common side effects include:

• Drowsiness: Chlorpheniramine and dextromethorphan can cause drowsiness, which may impair the ability to perform activities that require focus, such as driving.
• Dizziness or Lightheadedness: Some individuals may feel lightheaded or dizzy, especially when standing up too quickly.
• Dry Mouth or Throat: Chlorpheniramine can cause a dry mouth or throat, which may be uncomfortable.
• Nausea or Stomach Discomfort: Dextromethorphan may cause stomach upset, nausea, or vomiting, particularly at higher doses.
• Increased Blood Pressure: Pseudoephedrine can cause an increase in blood pressure, which may be concerning for individuals with hypertension or heart conditions.

Serious side effects may include:

• Allergic Reactions: If you experience signs of a serious allergic reaction, such as rash, itching, swelling, or difficulty breathing, seek emergency medical help immediately.
• Fast or Irregular Heartbeat: Pseudoephedrine may cause palpitations or an irregular heartbeat, particularly in those with underlying heart conditions. Consult a healthcare provider if this occurs.
• Respiratory Depression: Overuse of dextromethorphan may result in slowed breathing or difficulty breathing, which can be dangerous.

Before using Chlorpheniramine, Dextromethorphan, and Pseudoephedrine, keep the following precautions in mind:

• Pregnancy and Breastfeeding: Chlorpheniramine and dextromethorphan should only be used during pregnancy if the benefits outweigh the risks. Both medications pass into breast milk, so breastfeeding mothers should consult a healthcare provider before using this combination.
• High Blood Pressure: Pseudoephedrine can increase blood pressure. Individuals with hypertension or heart disease should use this medication with caution and consult a doctor before using it.
• Liver or Kidney Issues: People with liver or kidney problems may need a dose adjustment and should use this medication under the guidance of a healthcare provider.
• Alcohol Use: Avoid alcohol as it can intensify the sedative effects of chlorpheniramine and dextromethorphan, leading to excessive drowsiness or other dangerous side effects.
• Driving and Operating Machinery: Since chlorpheniramine and dextromethorphan can cause drowsiness, avoid activities requiring mental alertness, such as driving or operating heavy machinery, while using this medication.

 Chlorpheniramine, dextromethorphan, and pseudoephedrine can interact with several other medications, such as:

• Other Antihistamines: Combining chlorpheniramine with other antihistamines can increase the sedative effects, leading to drowsiness or dizziness.
• Other Cough Suppressants: Taking dextromethorphan with other cough suppressants can cause excessive sedation or respiratory depression.
• Monoamine Oxidase Inhibitors (MAOIs): MAOIs (used to treat depression) can cause severe reactions when combined with dextromethorphan, including dangerously high blood pressure.
• Blood Pressure Medications: Pseudoephedrine can increase blood pressure, so it may interact with medications for high blood pressure. Consult a healthcare provider before using this medication if you take blood pressure-lowering drugs.
• Alcohol: Alcohol can increase the sedative effects of chlorpheniramine and dextromethorphan, leading to extreme drowsiness and other side effects.

Always inform your healthcare provider about all medications you are taking, including over-the-counter drugs, to avoid harmful interactions.

For Chlorpheniramine, Dextromethorphan, and Pseudoephedrine, the typical dosage for adults is:
