About Cystaline
What Is Cystaline?
Cystaline is an effervescent tablet containing 600 mg of Acetylcysteine, manufactured by Millimed, a Thai pharmaceutical company. It works by breaking the disulfide bonds within the molecular structure of mucus, reducing its viscosity so it can be cleared from the airways more easily when coughing. Beyond its mucolytic action, Acetylcysteine is also a precursor of glutathione, which has antioxidant properties at the cellular level. Taking it in effervescent form lets the body absorb the medication faster than a standard swallowed tablet, since it is already dissolved into liquid before entering the digestive tract. Being manufactured locally in Thailand, Cystaline has wide distribution and is easy to find at general pharmacies.
What Is Cystaline Used For?
Cystaline's main use is to dissolve mucus and relieve productive cough in both acute and chronic respiratory conditions, such as bronchitis, tracheobronchitis, pneumonia, chronic asthmatic bronchitis, chronic emphysema, and bronchiectasis. It suits adults and teens aged 14 and up with a productive cough that is difficult to clear, especially during seasonal changes or a lingering cold that leaves mucus built up in the airways. People with chronic cough from smoking or air pollution can also use it to help clear built-up mucus. If you also have a high fever, severe chest pain, or are coughing up blood, see a doctor instead of self-treating.
What Is the Cystaline Dosage?
The recommended dosage of Cystaline is 1 tablet (600 mg) once daily, for adults and teens aged 14 and up only — there isn't enough safety data to recommend it for children under 14. Most adults don't need to adjust the dose up or down, except people with severe liver or kidney disease, who should consult a doctor or pharmacist first to determine an appropriate individual dose. Don't take more than 1 tablet a day without a doctor's advice.
When Should You Take Cystaline
The best time to take Cystaline is before the evening meal once daily, as stated on the label — different from some other effervescent mucolytics that are recommended with or after a meal. Taking it before dinner helps the medication stay active through the night, when mucus tends to build up more. If you forget your usual dose, take it as soon as you remember that day, but if it's close to bedtime or your next meal, skip the missed dose — don't double up to make up for it. Taking it around the same time each day gives the most consistent results.
Side Effects of Cystaline
Possible side effects of Cystaline include nausea, vomiting, heartburn, diarrhea, or mild stomach pain, which often improve when taken consistently at the recommended time, before the evening meal. Some people may experience allergic reactions such as itchy rash or hives, and those who are sensitive to the medication or have asthma may, in rare cases, experience bronchospasm. If you experience severe symptoms such as difficulty breathing or swelling of the face or throat, stop taking the medication and seek medical attention immediately. Most side effects are mild and tend to resolve on their own within a few days of adjusting the timing.
Contraindications and Precautions
Contraindications and precautions for Cystaline: anyone allergic to Acetylcysteine should not use this medication. People with peptic ulcers or duodenal ulcers should use it with caution, as it may irritate the mucous membrane of the digestive tract. Asthma patients should also use it carefully, since it can occasionally trigger bronchospasm. Pregnant and breastfeeding women should always consult a pharmacist before use. It is not recommended for children under 14, since there isn't enough safety data for this age group. Older adults or people with multiple underlying conditions should tell their pharmacist about all current medications before starting Cystaline, to reduce the risk of drug interactions.
Cystaline vs Other Effervescent Mucolytics
Among effervescent mucolytics with the same 600 mg Acetylcysteine active ingredient, Intimo Life carries three brands: Cystaline (Acetylcysteine) from Millimed, made in Thailand, a tube of 10 effervescent tablets suitable from age 14 and up; NAC Long (Acetylcysteine) from Menarini, also a tube of 10 effervescent tablets in a sugar-free formula suitable for children aged 6 and up; and Fluimucil A600 (Acetylcysteine) from Zambon, a box of 5 blister strips of 2 tablets each (10 total) with a lemon flavor. All three share the same active ingredient and mechanism, differing mainly in manufacturer, packaging, and labeled age range. Cystaline's standout advantage is being made directly in Thailand, making it the most accessible option in this group. In short: choose Cystaline if you're an adult or teen 14+ who wants a locally made, easy-to-find option, choose NAC Long if you need it for children aged 6+ or want a sugar-free option, and choose Fluimucil A600 if you prefer a lemon flavor and blister packaging.
Can Cystaline Be Taken With Other Medications?
Cystaline can generally be taken together with other expectorants or bronchodilators under a pharmacist's guidance, but it should not be taken at the same time as tetracycline antibiotics, since Acetylcysteine may reduce their absorption — if both are needed, space the doses at least 2 hours apart. It also should not be combined with cough suppressants, because doing so would cause the mucus that has already been loosened to build up in the airways instead of being cleared out. It's also best to space it at least 1-2 hours apart from certain antacids or activated charcoal, as these can likewise reduce the absorption of Acetylcysteine.
Where to Buy Cystaline
Where to Buy Cystaline
Order online at Intimo Life for nationwide delivery across Thailand within 1-3 business days. Packaging is discreet and does not identify the product on the outside of the parcel, and you can track the shipment status the entire way until it arrives.
To take Cystaline: drop 1 effervescent tablet into about half a glass of clean water, wait until the fizzing stops completely, then drink it right away. Don't let the solution sit too long, as the active ingredient degrades once exposed to air — drink it within a few minutes of dissolving. Use room-temperature or cool water, and avoid soda, tea, or coffee, which may reduce the medication's effectiveness.
Cystaline is not recommended for children under 14, since there isn't enough safety and dosing data for this age group. If a child under 14 has a productive cough, consult a doctor or pharmacist for a mucolytic labeled for a younger age range instead.
The price of Cystaline is shown in the product options above, and it may change depending on ongoing promotions. Add it to your cart to see the latest price before checking out.
Pregnant and breastfeeding women should always consult a doctor or pharmacist before using Cystaline, since safety data for this group is limited. A doctor will weigh the need and risk on a case-by-case basis before recommending it.
If you forget a dose of Cystaline, take it as soon as you remember that day, but if it's close to bedtime or your next dose, skip the missed one — don't take two tablets together to make up for it. Missing one dose isn't dangerous, but if it happens often and your cough isn't improving, consult a pharmacist.
After opening the Cystaline tube, always reseal the cap tightly to keep out moisture and air, which can cause the effervescent tablets to degrade early. Store in a dry place at room temperature away from direct sunlight. If a tablet changes color or smells unusual, don't take it.
Cystaline is generally used for around 5-10 days to relieve acute productive cough. If symptoms don't improve or get worse after more than a week of continuous use, consult a doctor or pharmacist for further evaluation. Patients with chronic respiratory disease who need long-term use should stay under a doctor's guidance.
Cystaline is a mucolytic that directly reduces mucus viscosity, unlike some cough syrups that are cough suppressants acting on the brain to reduce how often you cough. Which to choose depends on your symptoms — if you have thick mucus, choose a mucolytic; avoid a cough suppressant, as it can cause mucus to build up instead.
People with gastritis or a peptic ulcer should consult a doctor or pharmacist before taking Cystaline, since Acetylcysteine can irritate the stomach lining in some cases. Follow the label dosing — dissolve one tablet in half a glass of water once daily before the evening meal — and don't skip the evening meal after taking it. Stop taking it and tell your doctor if you have severe stomach pain.
