bedaquiline BDQ dosing schedule 14 days then alternate days tuberculosis

Important note first: Please follow your doctor's specific instructions. This is a general explanation of how bedaquiline (BDQ) is supposed to be dosed, but your doctor may have reasons for their specific timing.

How Bedaquiline (BDQ) Dosing Actually Works

The standard dosing schedule for bedaquiline in TB treatment is:
  • Days 1-14 (Weeks 1-2): 400 mg once daily (loading dose)
  • Weeks 3 onwards: 200 mg three times per week (at least 48 hours between doses - typically Monday, Wednesday, Friday)
So the "half dose, alternate days" your doctor is describing IS the standard next phase of treatment - it's not a reduction because something is wrong, it's the normal scheduled step-down after the initial 14-day loading period.

Your Specific Situation (Day 12)

You are on Day 12 and your doctor is already telling you to switch to the reduced dose. Here's the key question:
Your doctor likely wants you to start the alternate-day dosing from around Day 14/15 as scheduled. The most sensible interpretation is:
  1. Complete the full 14 days of daily dosing first (2 more days for you), then switch to the 3x/week reduced dose as the standard protocol requires.
  2. The ECG check is routine because bedaquiline can prolong the QT interval (affects heart rhythm), and the doctor is monitoring this before continuing.

What You Should Do

Call your doctor or the TB clinic today and ask them to clarify the exact date to start the reduced dose. Ask specifically:
  • "Should I finish Day 13 and 14 at full dose, then start the reduced schedule on Day 15?"
  • OR "Should I start the reduced dose from today (Day 12) instead?"
This is a 2-day difference, but with TB medications it matters to follow the exact plan. Since you can reach them easily, it's worth one quick call to confirm rather than guessing.
Bottom line: The "alternate days, half dose" is the completely normal second phase of bedaquiline treatment - not a sign of a problem. Your doctor is following the standard protocol. Most likely they want you to finish the 14-day loading dose first, but confirm this directly with them to be sure.

They asked me to come today but they didn't calculate the days and I don't have their contact what should I do now

This is a practical question, not a medical one I need to research further - I have the information needed from the previous search.
Here's what makes the most sense for your situation:

What to Do Right Now

You are on Day 12. You have 2 days left of the full dose.
The safest and most logical option is:
Continue your 400 mg daily dose for Day 13 and Day 14 (today and tomorrow), then start the 200 mg three-times-a-week schedule from Day 15.
Here's why this is the right call:
  • The 14-day loading dose exists for a pharmacological reason - it builds up drug levels in your body
  • Cutting it 2 days short is unlikely to cause serious harm, but completing it is the correct protocol
  • The doctor's instruction to "take alternate days and half dose" almost certainly refers to starting AFTER the 14-day period - they just miscounted the days when you visited

To Reach Your Doctor

  • Go back to the clinic or hospital in person if you can - even without an appointment, the front desk or a nurse can relay your question
  • If you were given any prescription paper or discharge slip, there may be a facility number on it
  • Ask your pharmacist - they dispensed the medication and often have the prescribing doctor's clinic contact
  • If you are in India (where BDQ is commonly prescribed for MDR-TB), your treatment is likely under a PMDT/NTEP centre - you can walk into any government TB centre for guidance
Do not skip or reduce today's dose while waiting for clarification. Take your regular full dose today, complete Day 14 tomorrow, then begin the reduced schedule.
