What is the active ingredient in Medicon capsules?

Medicon capsules typically contain dextromethorphan hydrobromide hydrate. Dextromethorphan is a non-opioid antitussive that suppresses coughs without the addictive properties of opioid medications. It is found in many over-the-counter products, sometimes combined with other medications like expectorants.

How does Medicon work to suppress coughs?

Dextromethorphan works by affecting the central nervous system to suppress the urge to cough. It primarily acts on the medulla oblongata, the brainstem region controlling involuntary functions like coughing, reducing the sensitivity of nerves that trigger the cough reflex.

What conditions do Medicon capsules treat?

Medicon capsules and similar products are used for temporary relief of coughs from various respiratory conditions, including the common cold, flu, acute and chronic bronchitis, pneumonia, and upper respiratory tract infections.

Administration

Always follow administration instructions on the product label or from a healthcare provider. Consult a doctor if the cough lasts over seven days or is accompanied by fever, rash, or headache.

Potential side effects of Medicon capsules

Common side effects include dizziness, drowsiness, nausea, vomiting, stomach pain, and restlessness. Less common, but more serious effects can include allergic reactions or signs of overdose like severe dizziness, extreme drowsiness, vision changes, or seizures. Seek medical attention for severe or persistent side effects or suspected overdose.

Interactions and precautions

Inform your doctor or pharmacist about all medications and medical conditions before taking Medicon due to potential drug interactions.

Important interactions to be aware of:

MAOIs: Avoid combining dextromethorphan with MAOIs, as this can cause potentially fatal serotonin syndrome. Do not use Medicon within two weeks of taking an MAOI.
Other Medications: Be cautious with certain antidepressants, triptans, and other cough/cold products that can increase side effect risks.
Alcohol: Avoid alcohol due to increased drowsiness and dizziness.

Precautions

Not for coughs with excessive phlegm or chronic coughs from smoking, asthma, or emphysema.
Consult a doctor if you have breathing problems, liver disease, or are pregnant or breastfeeding.
