What is drug resistance? Can I develop drug resistance with Heptavir 100mg Tablet?

Drug resistance is a state where the medicine which was once effective in treating an infection becomes ineffective.

Generally, drug resistance with Heptavir 100mg Tablet is more likely to happen if you take less dose than what is recommended.
