Product Description
Dextromethorphan Cough Medicine Patar Cap is a single-ingredient cough medicine built around dextromethorphan hydrobromide, without the added expectorants or antihistamines found in combination formulas. It suits a dry, non-productive cough.
📊 Key Facts
Mechanism — Dextromethorphan suppresses the cough center in the brain's medulla, reducing cough frequency without the respiratory depression seen with opioid antitussives.
History — Dextromethorphan has been used as a cough medicine in the US since 1958 and remains the most widely used non-opioid antitussive worldwide.
Single ingredient — Unlike formulas containing guaifenesin or terpin hydrate, Patar Cap is dextromethorphan alone, a focused option for dry cough.
🏭 Patar Cap is made by Patar Lab (2517) Co., Ltd., a Thai generic drug maker with long-standing experience in respiratory medicines.
⚠️ Patar Cap should not be used for chronic cough from smoking, asthma, chronic bronchitis, emphysema, or a cough with heavy phlegm, and it is sold only to buyers aged 17 and above with a limit per purchase.

About Patar Cap
What Is Patar Cap?
Patar Cap is a cough-relief capsule manufactured by Patar Lab (2517) Co., Ltd. Its active ingredient is dextromethorphan hydrobromide as a single active ingredient, without added expectorants or antihistamines found in typical combination cough formulas sold in Thailand.
Dextromethorphan is a non-opioid antitussive that acts on the cough center in the medulla of the brain, reducing the frequency and severity of coughing without the respiratory depression associated with opioid cough medicines. Because it contains dextromethorphan alone, Patar Cap suits people who want to target a dry cough directly without unnecessary added ingredients. It comes in packs of 10 capsules for convenient use.
What Is Patar Cap Used For?
Patar Cap is used to relieve cough from colds, bronchitis, and sinusitis, and to help clear phlegm, per the product label indications. Its dextromethorphan content acts on the brain's cough-control center to reduce how often you cough, making it suitable for a dry, scratchy cough or cough from an upper respiratory infection or a mild common cold.
Because it is a single-ingredient formula, Patar Cap does not contain a concentrated expectorant the way combination cough medicines do, so it tends to fit coughs with little or no phlegm better than those with thick, sticky phlegm. See a doctor or pharmacist if your cough doesn't improve within 7 days or if you develop a high fever.
How to Take Patar Cap / Dosage
How to take Patar Cap per the product label: adults take 2 capsules every 4 hours, and children aged 6-12 take 1 capsule every 4 hours. Swallow the capsules whole with plenty of water; food is not required, so you can take it before or after eating.
Do not exceed the labeled dose, and avoid using it for more than 7 days in a row without checking with a doctor or pharmacist. If you miss a dose, take it as soon as you remember, but if it's almost time for the next dose, skip the missed one and continue your normal schedule — never double up to make up for a missed dose. Patar Cap is intended for children aged 6 and above only; it is not recommended for younger children.
Side Effects of Patar Cap
Possible side effects of Patar Cap include drowsiness, dizziness, nausea, dry mouth, or mild constipation, which are usually mild and resolve once you stop taking it. Dextromethorphan has a strong safety profile at the recommended dose, but taking more than the labeled amount can cause dizziness, confusion, a rapid heartbeat, or hallucinations.
Avoid driving or operating machinery until you know how the medicine affects you. Stop taking it and see a doctor right away if you notice an allergic reaction such as a rash, difficulty breathing, or facial swelling.
Contraindications & Precautions
Do not use Patar Cap if you have chronic cough from smoking, asthma, chronic bronchitis, or emphysema, or a cough that produces a lot of phlegm, since suppressing the cough in these cases can cause mucus to build up in the airway. People with liver disease, kidney disease, or who are pregnant or breastfeeding should consult a doctor or pharmacist before using Patar Cap.
Patar Cap is sold only to buyers aged 17 and above, with a limit on the quantity per purchase to help prevent misuse. Always keep it out of reach of children.
How Does Patar Cap Compare to Other Cough Medicines?
Patar Cap uses dextromethorphan hydrobromide as a single active ingredient, without added expectorants or antihistamines, setting it apart from the three combination cough medicines also sold at Intimo Life.
Terco-D — a tablet with guaifenesin and terpin hydrate to help clear phlegm too; choose it for a productive cough at a lower price.
D-Coate — a coated tablet with a stronger combination formula than Terco-D; choose it for a productive cough needing a more potent antitussive.
Romivon — a soft gel capsule with bromhexine, a mucolytic; choose it when phlegm is thick and hard to swallow.
In short: choose Patar Cap for a dry cough with no phlegm and a single-ingredient formula, choose Terco-D or D-Coate for a productive cough needing an expectorant, and choose Romivon when phlegm is thick and sticky.
Can Patar Cap Be Taken with Other Medications?
Dextromethorphan in Patar Cap can interact with certain medications, particularly MAOI and SSRI antidepressants, which may raise the risk of serotonin syndrome when combined. Leave at least 14 days after stopping an MAOI before starting Patar Cap.
It's also best to avoid alcohol while taking it, since alcohol can add to its central nervous system depressant effect and increase drowsiness. If you're taking other regular medications, check with a doctor or pharmacist before starting Patar Cap to stay safe.
How Long Does Patar Cap Take to Work?
Patar Cap starts suppressing cough within about 15-30 minutes of taking it, and its effect lasts around 4 hours, which is why the label calls for redosing every 4 hours to keep your cough under control throughout the day.
Onset and duration can vary slightly from person to person depending on body weight, metabolism, and how severe the cough is. With consistent use at the recommended dose, cough symptoms typically start improving within 2-3 days.
Where Can I Buy Patar Cap?
Where Can I Buy Patar Cap?
Order Patar Cap online from Intimo Life, with delivery nationwide across Thailand in 1-3 business days. Packaging is discreet and does not indicate the product name.
Older adults generally use the same dose as other adults — 2 capsules every 4 hours. However, anyone with liver disease, kidney disease, or taking several regular medications should check with a doctor or pharmacist first for safety.
Dextromethorphan passes into breast milk in small amounts, so breastfeeding mothers should always consult a doctor or pharmacist before taking Patar Cap to weigh the individual risks and benefits.
At the recommended dose, dextromethorphan carries a very low risk of dependence. Taking much more than the labeled amount over time, however, can produce drug-like effects, so it should only be used at the dose stated on the label and no longer than necessary.
Coffee and tea don't cause a serious interaction with dextromethorphan, but caffeine can overstimulate the nervous system and disrupt the rest that helps you recover from a cough, so plain water is a better choice while taking this medicine.
Patar Cap is a capsule, so it's easy to carry and doesn't need measuring like syrup does, and it contains no added sugar or alcohol the way some cough syrups do — a good fit if you want to manage sugar intake or need something portable.
Opening a Patar Cap capsule and mixing it with water isn't recommended, since it can throw off the labeled dose. Swallow the capsule whole as directed — Patar Cap is intended only for children aged 6 and up who can swallow capsules.
After opening, keep Patar Cap in its original packaging at room temperature, away from sunlight and moisture, and use it before the expiry date printed on the pack or box. Don't carry it over to the next cough season without checking its condition first.
People with heart disease can generally take Patar Cap as directed, but because taking more than the labeled dose can cause an abnormally fast heartbeat, anyone with arrhythmia or serious heart disease should check with a doctor before use.
Patar Cap can help suppress cough whether it's triggered by allergies or a cold, but it doesn't treat the underlying allergy itself. If your allergy-related cough is chronic or comes with nasal congestion and a runny nose, see a doctor to address the root cause.
