1. Syrup: If you are using the syrup form of chlorpheniramine and hydrocodone, measure the prescribed dose using a measuring spoon or cup. The typical adult dose is 5 mL every 4-6 hours, up to a maximum of 6 doses per day.
2. Tablets: Take one tablet with a glass of water. The typical adult dose is 1 tablet every 4-6 hours, up to a maximum of 6 tablets per day.

Important Tips:

• Do not exceed the prescribed dose. Taking more than the recommended dose can increase the risk of serious side effects, including overdose.
• If you miss a dose, take it as soon as you remember, unless it is almost time for the next dose. In that case, skip the missed dose and continue your regular dosing schedule.
• Avoid alcohol or any sedative medications while taking this combination, as it can lead to severe drowsiness and other dangerous side effects.

• Chlorpheniramine: Chlorpheniramine works by blocking the effects of histamine, a chemical involved in allergic reactions. Histamine causes symptoms such as itching, sneezing, and runny nose by triggering inflammation in the body. By preventing histamine from binding to its receptors, chlorpheniramine helps reduce these allergic symptoms.
• Hydrocodone: Hydrocodone works as a cough suppressant. It acts on the brain’s cough center to reduce the urge to cough. In addition to suppressing coughing, hydrocodone also has mild analgesic (pain-relieving) effects, which can help alleviate discomfort caused by persistent coughing.

Together, these two active ingredients address both the underlying symptoms of respiratory infections (such as congestion and sneezing) and the discomfort caused by a persistent cough, providing relief for individuals suffering from cold or allergy symptoms.

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

• Drowsiness: Both chlorpheniramine and hydrocodone can cause drowsiness. While this may be helpful for those needing sleep, it can impair the ability to perform tasks that require focus and attention, such as driving.
• Dizziness or Lightheadedness: Some people may experience dizziness or lightheadedness, especially when standing up too quickly.
• Dry Mouth or Throat: Chlorpheniramine can cause a dry mouth or throat, which may be uncomfortable for some users.
• Nausea or Vomiting: Hydrocodone may cause nausea or vomiting, especially at higher doses or if taken on an empty stomach.
• Constipation: Hydrocodone, being an opioid, can slow down the digestive system, leading to constipation.

Serious side effects may include:

• Respiratory Depression: Overuse of hydrocodone can lead to respiratory depression, which can be life-threatening. This is more likely to occur if the medication is taken in excess or in combination with other CNS depressants, such as alcohol or sedatives.
• Allergic Reactions: Signs of a serious allergic reaction, such as rash, itching, swelling, or difficulty breathing, require immediate medical attention.

If you experience any of these serious side effects, stop using the medication and seek medical help immediately.

Before using Chlorpheniramine and Hydrocodone, there are several important warnings and precautions to keep in mind:

• Risk of Addiction: Hydrocodone is an opioid and can be addictive, especially if used in high doses or for extended periods. It should only be used as directed by a healthcare provider.
• Pregnancy and Breastfeeding: Chlorpheniramine and hydrocodone should only be used during pregnancy if the benefits outweigh the risks. Hydrocodone passes into breast milk, so it is not recommended for breastfeeding mothers unless deemed absolutely necessary.
• Respiratory Issues: People with respiratory issues, such as asthma, COPD, or other lung diseases, should use this medication with caution, as it may suppress breathing.
• Avoid Alcohol: Alcohol can enhance the sedative effects of chlorpheniramine and hydrocodone, increasing the risk of dangerous side effects such as drowsiness, dizziness, and respiratory depression.
• Driving and Operating Machinery: This medication can impair your ability to perform tasks that require alertness, so avoid driving or operating heavy machinery while using it.

Chlorpheniramine and hydrocodone can interact with several medications, including:

• Other CNS Depressants: Combining this medication with other central nervous system depressants (e.g., alcohol, benzodiazepines, or barbiturates) can increase the risk of sedation, dizziness, respiratory depression, or overdose.
• Other Antihistamines: Using other antihistamines along with chlorpheniramine may enhance the sedative effects, leading to excessive drowsiness or dizziness.
• Monoamine Oxidase Inhibitors (MAOIs): Taking hydrocodone with MAOIs (used to treat depression) can result in severe side effects like increased blood pressure and even life-threatening reactions.
• Antidepressants: Certain antidepressants may increase the sedative effects of hydrocodone and chlorpheniramine, leading to excessive drowsiness or other adverse reactions.

Always inform your doctor about all the medications you are taking, including over-the-counter drugs, prescriptions, and herbal supplements, to avoid harmful interactions.

For Chlorpheniramine and Hydrocodone, the typical dosage for adults is:

• Syrup: 5 mL (1 teaspoon) every 4-6 hours, up to 6 doses per day.
• Tablets: 1 tablet every 4-6 hours, not exceeding 6 tablets per day.

Always follow the prescribed dosage and consult your doctor if you have any questions or concerns.
