Omeprazole

Omeprazole is a medication commonly prescribed to reduce stomach acid production, offering relief for conditions like acid reflux, heartburn, and stomach ulcers.
It belongs to the class of drugs known as Proton Pump Inhibitors (PPIs), which can also protect the stomach from certain medications or combination of medications.

Omeprazole works by inhibiting the proton pump in the stomach lining, which reduces acid production.
This helps prevent and heal conditions like acid reflux and ulcers, providing relief and safeguarding the digestive system.

The usual starting dose of omeprazole is 10mg to 40mg a day, with a maximum daily dose of up to 120mg, taken in divided doses.

It is usually best to take omeprazole in the morning. If prescribed once a day, take it before breakfast. If prescribed twice a day, take it in the morning and evening.

Omeprazole may start providing relief within a few days, but it may take up to a month to work properly.

If you miss a dose of Lansoprazole:
- For once-a-day dosing: Take it as soon as you remember if it's within 12 hours of your next dose. If it's closer to your next dose, skip the missed one and continue as usual.
- For twice-a-day dosing: Take it as soon as you remember if it's within 4 hours of your next dose. If it's closer to your next dose, skip the missed one and continue as usual.
Never take double doses to make up for a missed one.
