Your healthcare provider will consider several factors when determining your clarithromycin dosage, including your age and weight, the type of infection, and other medications you are taking. The length of time you take the drug will depend on the type and severity of your infection. Some infections can be treated with as few as seven days of clarithromycin, while others require longer use.
There is no "standard" clarithromycin dose that is recommended for all situations. Your healthcare provider will calculate the appropriate amount by taking into account several factors, including:
- Your weight
- The severity of the infection
- The type of infection
- Type of bacteria causing the infection.
Make sure to carefully follow your healthcare provider's instructions with regards to taking this medicine. Also, make sure to finish your prescription, even if you start to feel better. Stopping clarithromycin too soon could lead to the development of antibiotic-resistant bacteria. The length of time your healthcare provider recommends that you take clarithromycin will depend on the type and severity of your infection. Some infections can be treated in as few as seven days; others require much longer use.
People with severe kidney disease (or people with both liver and kidney disease) may need a lower or less frequent clarithromycin dosage, as the liver and kidneys help to remove the medicine from the body. Typically, the dosage is reduced by half or taken half as often.
General Information on Your Clarithromycin DosageSome considerations for people taking clarithromycin include the following:
- The medication comes as regular (immediate-release) tablets, extended-release tablets, and an oral suspension.
- The regular tablets and oral suspension are usually taken twice a day (sometimes three times a day for certain infections). The extended-release form is taken just once a day.
- Make sure to shake the oral suspension well before each dose.
- You can take the tablets or oral suspension with food or on an empty stomach. However, the extended-release tablets must be taken with food, as they may not work as well if you take them on an empty stomach.
- Clarithromycin can be taken at any time of the day; however, make sure to take the medication at the same time(s) each day: every 12 hours (if you take it twice daily) or every 24 hours (if you take it once daily).
- For the medication to work properly, it must be taken as prescribed. Clarithromycin will not work if you stop taking it too soon.
- If you are unsure about anything related to your dosage or clarithromycin dosing in general, please talk with your doctor, nurse, or pharmacist.
