What is acne?

Acne is a skin condition that causes blemishes to form, most noticeably on the face. Better known as zits or pimples, these blemishes are the result of hormones increasing sebum production that—along with other substances—can clog the skin's pores. Acne usually begins around puberty when hormonal changes cause oil glands to kick into high gear and increase sebum production, but it can result in breakouts at other times for a variety of reasons.4,7

What’s the cause of acne?

Just under your skin, there are thousands of oil-producing glands called sebaceous glands. They're found all over the body, but most of them are on the face, upper back, and chest. Normally, oil passes through pores to the skin's surface. But when dead skin cells or excessive oil block the pore, acne can form as a result of a rapid increase in the growth of bacteria. These bacteria often cause inflammation, making the pimple red, sore, and occasionally full of pus.5-7

What are some common myths about acne?

Almost everyone has heard that certain foods like chocolate and soft drinks can cause acne—not true. Acne isn't the result of poor hygiene, either. Things like stress, fatigue, humidity, cosmetics, and menstrual cycles can aggravate acne, but they don't cause it. In addition, acne tends to run in families.7

When should I see a dermatologist?

Almost every teenager has at least an occasional whitehead, blackhead, or pimple. Having a few zits here and there is normal and can usually be managed with over-the-counter medications. However, more than 40% of teens will have acne conditions that require treatment by a doctor or a dermatologist.8

According to the American Academy of Dermatology, if any of these statements is true, it may be time to see a dermatologist9:

  • You are concerned about your acne
  • In addition to whiteheads or blackheads, you have painful, pus-filled lesions and reddened spots
  • None of the over-the-counter medications you have tried has worked
  • You are beginning to see scars or dark patches after pimples clear

How is it treated?

There is no instant cure for acne. Don't get discouraged when a popular product hasn't worked for you. People are different, and sometimes a treatment that works for one person won't work for another. A physician-directed course of treatment can take up to 12 weeks to produce results. Even after some initial success, breakouts can still occur, and subsequent treatments may be needed to keep acne under control.3 Your dermatologist will be able to choose a treatment regimen that's best for your skin type.

What types of treatments are available?

There are a number of treatments available for people with acne. For patients with only occasional breakouts, something like an over-the-counter benzoyl peroxide or salicylic acid acne treatment may do the job. However, those with moderate to severe acne might need a prescription medication. And for those with cystic acne—hard, painful bumps under the skin—something stronger may be needed.3 Ask your dermatologist about the severity of your acne and what type of product is right for you.

If I’ve got acne, how should I care for my skin?

  • Wash your face with a mild cleanser in the morning, at night, and after heavy exercise. Your dermatologist can recommend a cleanser for you9
  • Avoid excess scrubbing because it might increase irritation. Try to keep your hands, hair, and objects like straps, hats, and phones away from your acne9
  • Don't touch or squeeze pimples. This can irritate the skin and make acne worse, prolong healing time, and increase the risk of scarring9
  • Avoid using oily cosmetics. Look for noncomedogenic (oil-free) cosmetics for your foundation, blush, eye shadow, moisturizers, and hair-care products. Also, be sure to completely remove makeup before bed7
  • Be patient. Your acne may get worse before it gets better, and it usually takes at least a month to evaluate your treatment's effectiveness3,7
  • Follow your dermatologist's instructions and use medications as directed3

Indication and Usage

Solodyn is a tetracycline-class drug used to treat the pimples and red bumps (non-nodular inflammatory lesions) of moderate to severe acne in people 12 and older.

Solodyn is not effective for acne that is not red-looking (non-inflammatory), such as blackheads and whiteheads. It is not known whether it is effective to treat infections, whether it is safe for use in people under 12, or safe to use for longer than 12 weeks.

Important Safety Information for SOLODYN Tablets

  • Do not use Solodyn if you are allergic to any of the tetracycline class of drugs. Ask your doctor or pharmacist for a list of these drugs if you are not sure. Discontinue Solodyn right away if a rash or other allergic symptoms appear.
  • Before taking Solodyn, tell your doctor if you have: kidney or liver problems, diarrhea or watery stools, vision problems or other medical conditions, or if you plan to have surgery with anesthesia.
  • Tell your doctor about all your medications, as taking Solodyn with other medications can affect the way Solodyn or the other drugs work, especially birth control pills, blood thinners, and antacids. Solodyn should not be taken with penicillin antibiotics or with isotretinoin (Amnesteem, Claravis, Sotret).
  • Taking Solodyn while pregnant may cause serious side effects on the growth of bone and teeth of your baby, so tell your doctor if you are nursing or pregnant. If you become pregnant while taking Solodyn, stop taking it and call your doctor. If you are male and your partner is trying to conceive, do not take Solodyn.
  • Protect your skin from the sun. Avoid sunlight, sunlamps, and tanning beds as you may get severe sunburn. Avoid driving or operating dangerous machinery until you know whether Solodyn causes you to feel dizzy or light-headed, or a spinning feeling (vertigo).
  • Severe irritation and bleeding in the colon (pseudomembranous colitis) have been reported with most antibiotics and can range from mild to life-threatening. Talk to your doctor if you have watery diarrhea, diarrhea that doesn’t go away, or bloody stools.
  • Tell your doctor if you have symptoms of liver disease, including loss of appetite, tiredness, diarrhea, yellowing of skin or eyes, unexplained bleeding, confusion or sleepiness. Stop taking Solodyn and call your doctor if you have changes in your vision or unusual headaches, or if you get a fever, rash, joint pain or body weakness, as these could be signs of a serious condition.
  • The most common side effects are headache, tiredness, dizziness and itching.
