Recommended Dosage for Pharmaceutical T3 25mcg x 30
Dosage differs based on:
- Thyroid condition severity
- Age and body weight
- Response to treatment
- Coexisting conditions (e.g., heart disease)
📌 Your doctor will start on the lowest effective dose and adjust based on blood tests.
Typical clinician-guided principles include:
- Take exactly as prescribed
- Do not increase or reduce dosage independently
- Regular follow-up is essential to monitor thyroid levels
Patients must follow prescription label instructions carefully, as incorrect use can significantly affect heart rate, metabolism, and overall health.
How Does Liothyronine (T3) Work?
Liothyronine is a bioactive thyroid hormone responsible for regulating:
- Metabolic rate
- Energy production
- Heart function
- Body temperature
- Muscle and digestive activity
- Hormonal balance
T3 acts faster than T4 (Levothyroxine) because:
1️⃣ It does not require metabolic conversion
2️⃣ It acts directly on cellular receptors
3️⃣ It increases metabolism at the tissue level rapidly
This makes it suitable for specific therapeutic scenarios, but also increases the importance of medical monitoring.
