Biaxin SR (clarithromycin SR) is the extended-release version of regular Biaxin. For the most part the two medications are very similar, though there are important dosage distinctions and for some conditions regular Biaxin will be preferred; it is best to consult a doctor before switching to Biaxin SR.

Young patients may be instructed to take Biaxin SR, but in many cases the dosage strength will be too high. SR tablets should not be split, as this will cause too much medication to be released too soon, so some young patients will need to stick to regular Biaxin.

Depending on location, Biaxin SR may be known as Biaxin XL.

Conditions Treated

Like the regular version of this medication, Biaxin SR is effective against a range of bacteria and a range of bacterial infections. Bacterial resistance is a concern in some areas, and it is not effective against all types of bacteria, so for best results the bacteria should be identified by a doctor prior to starting treatment. Biaxin SR will not provide benefit against viral or fungal infections.

As mentioned above, some infections should not be treated with Biaxin SR if regular Biaxin is available; for instance, for tonsillitis or otitis media regular Biaxin tablets are preferred.

Biaxin SR is often used to treat:

  • Sinusitis
  • Pneumonia
  • Bronchitis

Biaxin SR may be used for infections other than those listed above as well.

Regular Biaxin is often preferred over Biaxin SR to treat:

  • Tonsillitis
  • Skin infections
  • Otitis media
  • Duodenal ulcer disease

In some cases Biaxin or Biaxin SR may not be the preferred type of antibiotic for a given infection, but when the preferred medication is unsuitable---due to allergies, unavailability, or so forth---Biaxin or Biaxin SR may be chosen instead.

Taking Biaxin SR

It is in dose amount and frequency of administration that Biaxin SR varies from regular Biaxin; while the regular version is typically taken twice per day, the SR version is taken just once per day. Dosage strength of Biaxin SR is typically doubled compared to regular Biaxin, sometimes a bit more than doubled. A doctor should advise dosage and frequency of administration, and doctor instructions should always be followed.

Treatment with Biaxin SR typically looks like:

  • For bronchitis - Take 1 gram (1000 mg) every 24 hours for 7 days.
  • For pneumonia - Take 1 gram every 24 hours for 7 days.
  • For sinusitis - Take 1 gram every 24 hours for 14 days.

Duration of treatment is typically the same regardless of if using regular tablets or Biaxin SR; in most cases, 7 to 14 days depending on the type and severity of the infection. Whichever one is being taken, it is important to continue treatment for the full duration regardless of feeling fine; failing to do so can result in a resurgence of the bacteria and may contribute to resistance.

Another difference is that, while food is optional with regular Biaxin, it is recommended to take each Biaxin SR dose with food.

Side Effects

Severe side effects from Biaxin SR are rare; most side effects are mild and may stop occurring after a few days of treatment, including:

  • Stomach discomfort
  • Mild diarrhea
  • Vomiting
  • Altered taste

Though unusual, more serious side effects may happen and do call for medical attention:

  • Pressure or pain in chest
  • Rapid or erratic heartbeat
  • Severe dizziness
  • Loss of consciousness
  • Difficulty breathing
  • Severe diarrhea
  • Liver problems---dark urine; light-colored stools; stomach pain that radiates to the back
  • Skin problems---swollen, blistered, or peeling skin; sores in mouth, nose or throat; red, irritated eyes

Biaxin SR can interact with other medications, including over-the-counter varieties. Be sure the prescribing doctor is aware of all other medications being taken, and double-check with a doctor before adding new medications during treatment. Though rare, interactions can be quite serious and even potentially fatal.
