Generic Restfine

Introduction

Restfine is a sleep‑promoting medication whose active ingredient is melatonin, a hormone that regulates the circadian rhythm. It is classified within the general health and sleeping‑aid groups and is widely used in Hong Kong for the short‑term management of sleep onset difficulties. Restfine is marketed by various manufacturers and is available as a generic formulation of melatonin. The product is also occasionally employed off‑label for jet lag and shift‑work sleep disorder, reflecting its role in synchronising internal biological clocks.

What is Restfine?

Restfine is the generic version of well‑known melatonin products such as Circadin, Natrol Melatonin, and Melatonin 5 mg tablets. It contains the same active compound, melatonin, and is produced by licensed pharmaceutical firms that meet the regulatory standards of the Hong Kong Department of Health. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Restfine Works

Melatonin is an endogenous hormone secreted by the pineal gland in response to darkness. It binds to melatonin receptors (MT1 and MT2) in the suprachiasmatic nucleus, the brain’s master clock, thereby signaling that night has begun. Exogenous melatonin from Restfine mimics this natural signal, advancing the timing of sleep onset. The pharmacokinetic profile shows rapid absorption, with peak plasma concentrations occurring 30–60 minutes after oral ingestion. The biological half‑life is approximately 30–50 minutes, allowing the effect to wane by early morning, which minimizes residual daytime sedation.

Conditions Treated with Restfine

• Primary insomnia (sleep onset type): The most common indication, especially in adults experiencing difficulty falling asleep within 30 minutes.
• Jet lag: Travelers crossing three or more time zones experience a misalignment of the internal clock; melatonin assists re‑synchronisation.
• Shift‑work sleep disorder: Workers with irregular hours benefit from melatonin to shift the circadian phase.

In Hong Kong, epidemiological surveys report that roughly 30 % of adults experience occasional insomnia, and up to 12 % report chronic sleep disturbances. The prevalence of shift‑work in the city’s service and finance sectors creates a sizable population that may benefit from melatonin therapy.

Who is Restfine For?

Restfine is appropriate for adults (≥18 years) who have difficulty initiating sleep, experience jet lag, or need to adjust to a non‑standard work schedule. It is particularly useful for individuals with a functional, healthy pineal gland and without severe psychiatric or neurological disorders that affect sleep architecture. Patients with uncontrolled hypertension, severe hepatic impairment, or those taking potent central nervous system depressants should consult a physician before use, as melatonin may potentiate sedation.

Risks, Side Effects, and Interactions

Common

• Drowsiness or next‑day sleepiness: Usually mild and resolves with dose timing adjustment.
• Headache: Transient, often improves with hydration.
• Stomach discomfort: May occur if taken on an empty stomach; food can mitigate this.

Rare

• Mood changes: Some users report mild irritability or feeling “blue”; monitor if symptoms persist.
• Hormonal effects: Long‑term high‑dose use could theoretically affect reproductive hormone balance, though evidence is limited.

Serious

• Allergic reactions: Urticaria, facial swelling, or difficulty breathing require immediate medical attention.
• Severe somnolence leading to accidents: Particularly when combined with alcohol or sedative medications.

Drug–Drug Interactions

• Anticoagulants (e.g., warfarin): Melatonin may modestly increase bleeding risk; periodic INR monitoring is advisable.
• Immunosuppressants (e.g., cyclosporine): Potential additive immunomodulatory effects.
• CNS depressants (e.g., benzodiazepines, antihistamines, alcohol): Combined use can enhance sedation.

Patients should disclose all current medications to their healthcare provider before initiating Restfine.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing: .5 mg to 5 mg taken 30–60 minutes before intended bedtime. Start with the lowest effective dose and titrate upward if needed.
• Missed dose: If the scheduled dose is forgotten, take it as soon as remembered provided there is at least 4 hours before the next intended sleep time; otherwise skip and resume the regular schedule.
• Overdose: Accidental ingestion of up to 10 mg generally produces only mild drowsiness; however, higher amounts may cause pronounced sedation, hypotension, or gastrointestinal upset. Seek medical advice if severe symptoms develop.
• Precautions: Avoid concurrent consumption of alcohol or potent sedatives. Patients with liver disease may require dose reduction due to altered metabolism. Store tablets in a dry place at 20–25 °C; do not refrigerate unless specified by the manufacturer.

FAQ

• What is the typical onset time for Restfine's sleep‑inducing effect?
  Restfine usually begins to work within 30–60 minutes after oral intake. The timing aligns with melatonin's natural rise in the evening, helping users fall asleep more quickly.

• Can Restfine be used by individuals who are pregnant or breastfeeding?
  Safety data for melatonin during pregnancy and lactation are limited. Current guidelines advise caution and recommend consulting a healthcare professional before use in these populations.

• Does the formulation of Restfine differ between regions such as the US, EU, and Asia?
  The active ingredient remains melatonin, but excipients (inactive ingredients) may vary to meet local regulatory requirements. For example, Asian formulations often use glucose‑based fillers, while some EU products use lactose.

• How should Restfine be stored in a humid climate like Hong Kong?
  Keep the tablets in a tightly sealed container away from moisture. A cabinet or drawer that is not located near kitchens or bathrooms is optimal to preserve potency.

• Is Restfine detectable in standard drug‑testing panels?
  Melatonin is not a prohibited substance and is not screened for in typical employment or sport drug tests. However, athletes should verify with their governing bodies.

• What are the differences between immediate‑release and prolonged‑release melatonin products?
  Immediate‑release (IR) formulations, like Restfine, deliver melatonin quickly to aid sleep onset. Prolonged‑release (PR) versions maintain plasma levels longer, targeting sleep maintenance. Restfine is an IR product designed for sleep initiation.

• Can Restfine be taken with citrus juices such as orange or grapefruit juice?
  Citrus juices do not significantly affect melatonin absorption. Nevertheless, taking the tablet with a light snack or water is generally recommended to minimise gastrointestinal discomfort.

• What should a traveler know about importing Restfine into Hong Kong for personal use?
  Personal import of up to 30 days’ supply of melatonin for individual use is permitted under Hong Kong customs regulations, provided the product is correctly labeled and sourced from a reputable supplier.

• Are there any known contraindications for older adults (≥65 years) using Restfine?
  Older adults may be more sensitive to sedative effects and should start with the lowest dose (.5 mg). Monitoring for daytime drowsiness and falls is prudent.

• Does Restfine have any impact on blood sugar levels for diabetic patients?
  Current evidence does not indicate a direct effect of melatonin on glucose regulation. Diabetic patients should continue routine monitoring and discuss any sleep aid with their clinician.
