This is a commonly prescribed therapeutic drug for tinnitus in Japan. Mastering the correct usage and dosage, understanding precautions, and adopting a healthy lifestyle can help improve efficacy and reduce adverse reactions.
I. Usage and Dosage of Stomin
1. Standard Adult Dosage
(1) The usual adult dose is 2 tablets per dose, 3 times daily, taken orally after meals.
(2) The total daily dose is 6 tablets, containing 180mg of nicotinamide and 36mg of papaverine hydrochloride.
2. Significance of Postprandial Administration
(1) "Postprandial" means within 30 minutes after a meal.
(2) This reduces direct gastric mucosal irritation, lowering the risk of gastrointestinal side effects such as loss of appetite and heartburn.
3. Individualized Adjustment
(1) Dosage may be adjusted appropriately depending on age and symptoms.
(2) Elderly patients often require reduced dosage due to declining physiological functions; for those with mild or severe symptoms, the doctor will adjust the dose accordingly.
(3) Do not adjust the dosage on your own.
II. Precautions for Use
1. Safety Warning on Administration Method
(1) Medications in PTP packaging must be removed from the PTP sheet before taking.
(2) Swallowing the PTP sheet directly may cause sharp edges to pierce the esophageal mucosa, leading to serious complications such as perforation and mediastinitis.
2. Review of Contraindications
(1) Contraindicated in patients with a history of hypersensitivity to any component of this product.
(2) Patients with glaucoma (symptoms may worsen).
(3) Patients with atrioventricular block (may trigger paroxysmal tachycardia).
3. Monitoring for Side Effects
(1) Observe physical reactions during medication; common side effects include loss of appetite, heartburn, palpitations, dizziness, drowsiness, constipation, dry mouth, rash, and facial flushing.
(2) If any abnormalities occur, discontinue use promptly and consult a doctor. Rare but serious allergic liver injury should also be watched for.
4. Precautions for Special Populations
(1) Pregnant women: Use only if the potential benefit justifies the potential risk.
(2) Breastfeeding women: Weigh the benefits and risks before deciding whether to continue breastfeeding.
(3) Children: No clinical trial data available; use is not recommended.
(4) Elderly: Use reduced dosage and monitor closely.
5. Drug Interaction Reminder
No specific interactions are listed, but as it contains papaverine, caution is needed when used concomitantly with antihypertensives, CNS depressants, or other vasodilators. Inform your doctor of all medications you are taking.
6. Missed Dose Management
(1) If you miss a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and take the next dose as scheduled.
(2) Never take a double dose.
III. Healthy Lifestyle for Patients
1. Avoiding Factors That Worsen Tinnitus
(1) Reduce noise exposure: Avoid prolonged exposure to high-volume environments (KTV, construction sites, high-volume headphones); wear noise-protective earplugs when necessary.
(2) Control caffeine intake: Strong tea, coffee, energy drinks may intensify tinnitus perception.
(3) Quit smoking and limit alcohol: Nicotine constricts blood vessels, reducing inner ear blood flow; alcohol may dilate blood vessels and interact with the drug's effects.
2. Diets Beneficial for Inner Ear Health
(1) Foods rich in B vitamins: Whole grains, lean meats, eggs, legumes – to support nerve function.
(2) Foods rich in antioxidants: Dark-colored vegetables, blueberries, nuts – to reduce oxidative stress damage.
(3) Adequate hydration: 1.5–2 liters per day – to avoid dehydration that may impair inner ear circulation.
3. Regular Routine and Stress Management
(1) Ensure adequate sleep: 7–8 hours per night; drowsiness may be more pronounced early in treatment – adjust your schedule accordingly.
(2) Manage stress: Long-term anxiety and tension can worsen tinnitus perception – try deep breathing, meditation, or listening to soft music.
(3) Avoid excessive fatigue: Tinnitus often intensifies under fatigue – balance work and rest.
