How to take this drug

This is not a tablet — it is an injection given under the skin (subcutaneous). You take it every 2 weeks for the first 3 doses (at week 0, 2, and 4), then once every 4 weeks after that. Your doctor or nurse may teach you how to inject it yourself at home using a pre-filled syringe.

What if I Miss a Dose?

If you miss a dose, take it as soon as you remember and then adjust your next dose schedule from that date. Do not take a double dose. Contact your doctor for guidance on when to take the next one.

What to watch out for

This is a specialist prescription medicine — do not buy from unverified sources or roadside sellers; it must be stored in a fridge and handled properly. Always attend your follow-up appointments so your doctor can monitor your liver and check for infections. Do not share this medicine with anyone else, even if they have similar symptoms.
