|Amoxicillin with Clavulanic Acid
Common brand names: Augmentin, Amoclan, Clavamox
Description: Amoxicillin with clavulanic acid is a member of the penicillin class of antibiotics. It is classified as extended-spectrum. This means it can kill a wider range of bacteria than penicillin VK. It is better absorbed than ampicillin. It has a longer effect than either penicillin VK or ampicillin.
Dental uses: Amoxicillin with clavulanic acid is used to treat some dental infections that are resistant to other penicillins. The clavulanic acid blocks an enzyme produced by some bacteria. The enzyme stops some penicillin drugs from working.
Amoxicillin with clavulanic acid is used for:
- Complicated tooth infections
- Complicated root canal infections
- Complicated abscesses, especially those extending into the sinuses, gums and bone
- Gum infections that haven't responded to other drugs
- Placement of dental implants in the upper sinus
In certain cases, your dentist will collect a sample of the infection and send it to a laboratory. The laboratory can test to see whether amoxicillin with clavulanic acid is likely to work.
Dosages for dental purposes: A typical adult dose is 250 milligrams to 500 milligrams every 8 hours. It may be prescribed for 7 to 10 days.
As with all medicines, be sure to follow your doctor's prescription. Take amoxicillin with clavulanic acid for the prescribed length of time, even if you start to feel better. Do not stop taking it without talking to your doctor. Stopping an antibiotic too soon may cause bacteria to become resistant to antibiotics. This means the antibiotics won't work the next time.
Concerns and possible side effects: Tell your dentist and physician about all the medicines you take. This should include over-the-counter vitamins and herbal supplements. Also, let your dentist know if you have had a sensitive or allergic reaction to any medicine. If you are pregnant or nursing, or might be pregnant, talk to your primary care doctor before starting any new medicine. This also includes vitamins and supplements.
Amoxicillin with clavulanic acid can make birth control pills less effective. Therefore, you should discuss this issue with your prescribing doctor.
Amoxicillin with clavulanic acid may cause several side effects. Nearly 10% of patients have one or more of these side effects.
People taking blood-thinning drugs (for example, warfarin) may be more likely to bleed while taking amoxicillin with clavulanic acid.
This medicine may cause nausea, vomiting, diarrhea and yeast infections. A mild rash is a common side effect. It is usually not serious. But you may not be able to tell if this is a common rash or one that is a sign of an allergic reaction. Therefore, tell your doctor about the rash. Sometimes, amoxicillin turns the tongue black. This is known as black hairy tongue. It often goes away.
If you are diabetic, use Clinistix or Tes-Tape (not Clinitest) to test your urine for sugar while taking this drug. Clinitest may give a false positive reading while you are taking a cephalosporin drug.
If you are allergic to this drug or another penicillin drugs, do not take it. Allergic reactions vary. Some people get a rash. Some have a drop in blood pressure. In others, the airway swells and they cannot breathe.
Tell your doctor about any reaction to a prescribed medicine, no matter how minor it might be.
