Myrac is used for:
Treating infections caused by certain bacteria. It may also be used with other medicines to treat severe acne. It may also be used for other conditions as determined by your doctor.
Myrac is a tetracycline antibiotic. It works by slowing the growth of certain bacteria and allowing the body's immune system to destroy them.
Do NOT use Myrac if:
- you are allergic to any ingredient in Myrac or to other tetracyclines (eg, doxycycline)
- you are taking acitretin, isotretinoin, a live oral typhoid vaccine, methoxyflurane, or a penicillin
Contact your doctor or health care provider right away if any of these apply to you.
Before using Myrac:
Some medical conditions may interact with Myrac. 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 asthma, kidney or liver problems, or an autoimmune disorder (eg, lupus)
Some MEDICINES MAY INTERACT with Myrac. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Aluminum salts (eg, carbonate) or cimetidine because they may decrease Myrac's effectiveness
- Acitretin, anticoagulants (eg, warfarin), digoxin, ergot alkaloids and derivatives (eg, ergotamine), insulin, isotretinoin, methotrexate, methoxyflurane, or theophyllines because the risk of their side effects may be increased by Myrac
- Live oral typhoid vaccine, oral contraceptives (birth control pills), or penicillins because their effectiveness may be decreased by Myrac
This may not be a complete list of all interactions that may occur. Ask your health care provider if Myrac 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.
How to use Myrac:
Use Myrac as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with Myrac. Talk to your pharmacist if you have questions about this information.
- Take Myrac by mouth with or without food.
- Take Myrac with a full glass of water (8 oz/240 mL). Do not lie down for 30 minutes after taking Myrac.
- If you also take an antacid that has aluminum, calcium, or magnesium in it; bismuth salts (eg, bismuth subsalicylate); colestipol; iron salts (eg, iron sulfate); urinary alkalinizers (eg, sodium bicarbonate); vitamins or minerals; sucralfate; didanosine; quinapril; or zinc salts (eg, zinc sulfate), do not take them within 2 to 3 hours before or after taking Myrac. Check with your doctor if you have questions.
- To clear up your infection completely, take Myrac for the full course of treatment. Keep taking it even if you feel better in a few days.
- Myrac works best if it is taken at the same time each day.
- If you miss a dose of Myrac, 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 Myrac.
Important safety information:
- Myrac may cause dizziness, lightheadedness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Myrac with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Long-term or repeated use of Myrac 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.
- Myrac may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Myrac. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
- Myrac only works against bacteria; it does not treat viral infections (eg, the common cold).
- 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.
- Tell your doctor or dentist that you take Myrac before you receive any medical or dental care, emergency care, or surgery.
- Be sure to use Myrac 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.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Myrac. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Use Myrac with caution in the ELDERLY; they may be more sensitive to its effects.
- Use Myrac with extreme caution in CHILDREN younger than 10 years old who have diarrhea or an infection of the stomach or bowel.
- Myrac should not be used in CHILDREN younger than 8 years old; safety and effectiveness in these children have not been confirmed. Using Myrac in CHILDREN younger than 8 years old or in women during the last half of pregnancy may cause a permanent change in the tooth coloring of the child.
- PREGNANCY and BREAST-FEEDING: Myrac has been shown to cause harm to the fetus. If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Myrac while you are pregnant. Myrac is found in breast milk. Do not breast-feed while taking Myrac.
