The recommended dosage and administration of Sivextro are described in Table 1.
Table 1: Dosage of Sivextro
|Infection||Route||Dosage||Frequency||Infusion Time||Duration of Treatment|
|Acute Bacterial Skin and Skin Structure Infections (ABSSSI)||Intravenous||200 mg||Once daily||1 hour||6 days|
|Oral||200 mg||Once daily||Not Applicable|
No dose adjustment is necessary when changing from intravenous to oral Sivextro.
If patients miss a dose, they should take it as soon as possible anytime up to 8 hours prior to their next scheduled dose. If less than 8 hours remain before the next dose, wait until their next scheduled dose.
What drugs interact with Sivextro?
- Orally administered Sivextro inhibits Breast Cancer Resistance Protein (BCRP) in the intestine, which can increase the plasma concentrations of orally administered BCRP substrates, and the potential for adverse reactions.
- If possible, an interruption in the treatment of the co-administered BCRP substrate medicinal product should be considered during treatment with Sivextro, especially for BCRP substrates with a narrow therapeutic index (e.g., methotrexate or topotecan).
- If coadministration cannot be avoided, monitor for adverse reactions related to the concomitantly administered BCRP substrates, including rosuvastatin.
Is Sivextro safe to use while pregnant or breastfeeding?
- Based on animal reproduction studies, Sivextro may cause fetal harm when administered to pregnant women.
- The available data on the use of Sivextro in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
- Advise pregnant women of the potential risks to a fetus.
- There is no information on the presence of tedizolid in human milk. Tedizolid is present in rat milk. When a drug is present in animal milk, it is likely that the drug will be present in human milk.
- There are no data on the effects of Sivextro on the breastfed child or on milk production.

Staph (Staphylococcus) Infection
Staphylococcus or staph is a group of bacteria that can cause a multitude of diseases. Staph infections can cause illness directly by infection or indirectly by the toxins they produce. Symptoms and signs of a staph infection include redness, swelling, pain, and drainage of pus. Minor skin infections are treated with an antibiotic ointment, while more serious infections are treated with intravenous antibiotics.
MRSA (methicillin-resistant Staphylococcus aureus) bacteria causes skin infections with the following signs and symptoms: cellulitis, abscesses, carbuncles, impetigo, styes, and boils. Normal skin tissue doesn't usually allow MRSA infection to develop. Individuals with depressed immune systems and people with cuts, abrasions, or chronic skin disease are more susceptible to MRSA infection.
Is a Staph Infection Contagious?

8 Skin Warning Signs to Worry About in a Rash
Most of the rashes are harmless and may not indicate anything serious. However, if there are these accompanying symptoms along with the skin rash, it may signify something serious.
Are Skin Rashes Contagious?
Direct and indirect contact can spread some types of rashes from person to person. Rash treatment depends upon a rash's underlying cause. A rash that sheds large amounts of skin warrants urgent medical attention. Rashes can be either contagious or noncontagious. Noncontagious rashes include seborrheic dermatitis, atopic dermatitis, contact dermatitis, stasis dermatitis, psoriasis, nummular eczema, drug eruptions, hives, heat rash (miliaria), and diaper rash. Rashes usually considered contagious include molluscum contagiosum (viral), impetigo (bacterial), herpes (herpes simplex, types 1 and 2 viruses), rash caused by Neisseria meningitides (N. meningitides) (bacterial), rash and blisters that accompany shingles (herpes zoster virus), ringworm (fungal) infections (tinea), scabies (itch mite), chickenpox (viral), measles and rubella (viral), erythema infectiosum (viral), pityriasis rosea (viral), cellulitis and erysipelas (bacterial), lymphangitis (bacterial, and folliculitis (bacterial).
Staph Infection Causes
Staph or Staphylococcus is a group of bacteria that is found over the skin of most individuals. Staph bacteria usually live inside the nose, but they do not cause an infection. Staph infections may turn deadly if the bacteria invade deeper into the body, entering the bloodstream, joints, bones, lungs, or heart.
