Thanks for writing to us.
Ideally the best way to prevent typhoid while traveling to endemic countries is by taking a single shot of conjugated vaccine at least 2 weeks before travel.
If time is an issue for you, then I would advice
1. Strict water and food hygiene while traveling.
2. The pills you mentioned could be OK.
