What conditions is minocycline 100 mg used to treat?
Minocycline is a tetracycline antibiotic. A 100 mg dose is commonly used for bacterial infections where clinicians want a tetracycline option, including:
- Acne (especially more severe inflammatory acne such as cystic or nodulocystic acne)
- Certain skin and soft-tissue infections
- Some respiratory tract infections
- Some sexually transmitted infections (depending on the organism and local guideline)
- Other bacterial infections when a clinician chooses minocycline based on the bacteria’s expected susceptibility
How does minocycline work?
Minocycline kills or stops the growth of bacteria by interfering with bacterial protein production. That is why it can treat infections caused by susceptible bacteria.
What should you know before taking minocycline 100 mg?
- It is an antibiotic, so it won’t treat viral infections like colds or flu.
- Minocycline can interact with some medicines and minerals; take it only as directed by your prescriber/pharmacist.
- Using antibiotics when they are not needed can increase the risk of antibiotic resistance.
What side effects are most commonly associated with minocycline?
Commonly reported side effects include:
- Stomach upset, nausea, or diarrhea
- Dizziness or headache
- Sun sensitivity (you may burn more easily)
Get urgent medical care for severe allergic reactions or serious reactions (for example, widespread rash, swelling of the face, or trouble breathing).
When should you contact a clinician while on minocycline?
Contact a clinician promptly if you develop:
- Severe or persistent diarrhea
- Signs of liver problems (such as yellowing of the skin/eyes or dark urine)
- Severe rash or blistering skin changes
- Persistent dizziness or vision changes
If you tell me what infection or condition you’re asking about (for example, acne, a specific diagnosis, or a prescription label), I can narrow the answer to the most likely intended use of minocycline 100 mg in that situation.
