Althromicin is used for treating infections caused by certain bacteria. Althromicin is a macrolide antibiotic. It works by stopping the growth of or killing sensitive bacteria by reducing the production of important proteins needed by the bacteria to survive.
Use Althromicin as directed by your doctor.
- Take Althromicin by mouth with or without food.
- Althromicin works best if it is taken at the same time each day.
- Continue to take Althromicin even if you feel well.
- Do not miss any dose. If you miss a dose of Althromicin, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Althromicin.
Store Althromicin at room temperature, between 68 and 77 degrees F (20 and 25 degrees C), in a tightly closed container. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Althromicin out of the reach of children and away from pets.

- you are allergic to any ingredient in Althromicin or to any other macrolide (eg, erythromycin)
- you are taking cisapride, cyclosporine, dofetilide, eletriptan, an ergot alkaloid (eg, dihydroergotamine, ergotamine), an H1 antagonist (eg, astemizole, terfenadine), pimozide, a QT-prolonging agent (eg, quinidine, sotalol, thioridazine), a quinolone (eg, ciprofloxacin), or sumatriptan.
Contact your doctor or health care provider right away if any of these apply to you.
Some medical conditions may interact with Althromicin. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have diarrhea, a stomach infection, a blood disorder, severe kidney problems, or liver problems.
Some medicines may interact with Althromicin. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Aldosterone blockers (eg, spironolactone), anticoagulants (eg, warfarin), benzodiazepines (eg, alprazolam), buspirone, carbamazepine, cilostazol, cisapride, colchicine, corticosteroids (eg, hydrocortisone), cyclosporine, digoxin, disopyramide, eletriptan, ergot alkaloids (eg, ergotamine, dihydroergotamine), H1 antagonists (eg, astemizole, terfenadine), HMG-CoA reductase inhibitors (eg, simvastatin), imatinib, macrolide immunosuppressants (eg, tacrolimus), macrolides and ketolides (eg, azithromycin, erythromycin), phosphodiesterase type 5 inhibitors (eg, sildenafil), rifampin, sumatriptan, theophyllines, or verapamil because their actions and the risk of their side effects may be increased by Althromicin
- Dofetilide, macrolides and ketolides (eg, azithromycin, erythromycin), pimozide, QT-prolonging agents (eg, quinidine, sotalol, thioridazine), quinolones (eg, ciprofloxacin), or streptogramins (eg, mikamycin) because serious, possibly life-threatening side effects on the heart or irregular heartbeat may occur
- Rifampin because it may decrease Althromicin's effectiveness.
This may not be a complete list of all interactions that may occur. Ask your health care provider if Althromicin may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
Important Althromicin Safety Information
- Althromicin only works against bacteria; it does not treat viral infections (eg, the common cold).
- Long-term or repeated use of Althromicin may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Be sure to use Althromicin for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- Lab tests, including complete blood cell counts, may be performed while you use Althromicin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Althromicin should not be used in children younger 6 months; safety and effectiveness in these children have not been confirmed.
- Pregnancy and breast-feeding: Althromicin has been shown to cause harm to the fetus. Althromicin is not recommended for use during pregnancy except when no other antibiotics can be used. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Althromicin while you are pregnant. It is not known if Althromicin is found in breast milk. If you are or will be breast-feeding while you use Althromicin, check with your doctor. Discuss any possible risks to your baby.
