Who is this for?
Daclatasvir is an antiviral medicine that fights the hepatitis C virus by blocking a protein the virus needs to multiply in your body. It is usually taken together with another antiviral drug called sofosbuvir to clear the virus from your system.

Explore this drug
Take one 60mg tablet once a day, with or without food, at about the same time each day. It must be taken together with sofosbuvir (and sometimes ribavirin) as prescribed by your doctor — never take daclatasvir alone. Treatment usually lasts 12 weeks, but your doctor will tell you exactly how long. In Nigeria, it is available as Mydekla 60 Tablet.
If you miss a dose and it is less than 20 hours since you were supposed to take it, take it as soon as you remember. If it is more than 20 hours late, skip that dose and take the next one at your normal time. Do not take two tablets at once to make up for the missed dose.
Always complete the full course of treatment even if you start feeling fine — stopping early can allow the hepatitis C virus to come back and become harder to treat. Only buy Mydekla or any daclatasvir brand from licensed pharmacies, not from roadside sellers or unverified online shops, as fake hepatitis C drugs are common. Do not share this medicine with anyone else, even if they also have hepatitis C, as treatment must be prescribed individually by a doctor.
Do not take daclatasvir with certain TB drugs like rifampicin or certain HIV drugs like efavirenz, as they can reduce its effectiveness — always tell your doctor about all medicines you are taking. Avoid herbal remedies like St. John's wort as they can also make daclatasvir less effective. Amiodarone (a heart drug) combined with daclatasvir and sofosbuvir can cause dangerously slow heartbeat, so inform your doctor if you use any heart medication.

Is it safe to take Daclatasvir with your other drugs?
Daclatasvir is not recommended during pregnancy or breastfeeding unless your doctor decides the benefit outweighs the risk — consult your doctor before using it if you are pregnant, planning to become pregnant, or breastfeeding.
Store at room temperature, away from direct sunlight and heat — this is important in hot Nigerian weather. Keep the tablets in their original container, away from moisture and humidity. Always store out of reach of children.
