Starting Fanapt: The Initial Titration Phase
When you first begin taking Fanapt, your doctor will likely prescribe a special starter pack containing different dose strengths for the first few days. This slow, deliberate increase, or titration, is critical for minimizing the risk of orthostatic hypotension—a sudden drop in blood pressure when you stand up. Following this schedule precisely as directed by your healthcare provider is essential for your safety.
General Approach to Starting Fanapt
Your doctor will provide a specific schedule tailored to your needs. This often involves starting with a low amount and gradually increasing it each day over a period of about four days until a target level is reached. The level may be further adjusted based on your response and tolerance.
Symptoms may not improve immediately during this initial period due to the slow ramp-up. It can take one to two weeks before you may feel the full therapeutic benefit.
Following the Prescribed Schedule
Once the initial phase is complete, you will move to a schedule determined by your healthcare provider. Consistency is key to effective treatment.
Core Rules for Taking Fanapt
- Follow the prescribed schedule: Take your medication exactly as instructed by your doctor.
- Swallow tablets whole: Do not crush, split, or chew the tablets. They must be swallowed whole with a glass of water unless otherwise advised by your doctor.
- With or without food: Fanapt can be taken with or without a meal. However, if it causes stomach upset, taking it with food may help.
- Adherence is crucial: Do not stop taking your medication, even if you start to feel better. Sudden discontinuation can cause your symptoms to return or worsen.
- Set reminders: To ensure you take your medication consistently, linking it to a daily habit, setting an alarm, or using a pill organizer can be helpful.
Managing Missed Doses and Resuming Treatment
If you miss a dose of Fanapt, handle it according to the timing of your next scheduled dose. If you miss a dose but remember soon after, take it as soon as you can. However, if it is almost time for your next scheduled dose, skip the missed dose and resume your regular schedule. Never take more than your prescribed amount to make up for a missed one.
Re-Starting Fanapt After a Break
If you miss more than three consecutive days of medication, you must contact your doctor before restarting. Do not resume at your previous level. Your doctor will likely instruct you to restart at a lower amount and go through the initial adjustment process again to avoid potential side effects.
Important Safety Considerations
While taking Fanapt, it is important to be aware of potential side effects and interactions:
- Orthostatic Hypotension: The slow initiation helps mitigate this, but it is still a risk, especially during adjustments to the amount taken. To minimize risk, rise slowly from a sitting or lying position.
- QT Prolongation: Fanapt can affect your heart rhythm. Tell your doctor if you have a history of heart problems or are taking other medications that can cause QT prolongation.
- Metabolic Changes: Monitoring blood sugar, cholesterol, and weight is important, as Fanapt can potentially cause changes in these levels.
- Alcohol: Avoid drinking alcohol while on Fanapt, as it can increase drowsiness and other side effects.
- Boxed Warning: There is a boxed warning regarding the increased risk of death in elderly patients with dementia-related psychosis. Fanapt is not approved for this use.
Comparison: Fanapt Initial vs. Ongoing Phase
| Feature | Initial Phase | Ongoing Phase |
|---|---|---|
| Goal | Allow the body to adjust slowly and safely to the medication. | Maintain a consistent therapeutic level of medication for symptom management. |
| Amount | Low starting level, with gradual increases over several days as directed by a healthcare provider. | Stable level, adjusted for individual needs as determined by a healthcare provider. |
| Duration | Short-term, usually about 4-7 days, guided by specific instructions. | Long-term, as prescribed by your doctor. |
| Symptom Relief | May be delayed, as the level is not yet at a therapeutic level. | Consistent symptom control is the expected outcome. |
| Primary Risk | Orthostatic hypotension and associated dizziness are more likely. | General side effects and risks associated with long-term use. |
Conclusion
Taking Fanapt safely and effectively requires careful adherence to your doctor's instructions, especially during the initial phase. Following the correct schedule, understanding how to handle missed doses, and being aware of key precautions are all essential for successful treatment. Consistent communication with your healthcare provider and pharmacist is crucial for managing your medication and overall health.
