In addition, you must have a pregnancy blood test each month while you are taking this medicine and one month after treatment is completed.

It is very important that you take isotretinoin only as directed by your doctor . Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.

Isotretinoin causes birth defects in humans if taken during pregnancy. If you suspect that you may have become pregnant, stop taking this medicine and check with your doctor right away.
Using this medicine while you are pregnant can cause very serious birth defects. Use two forms of effective birth control to keep from getting pregnant while you are using this medicine (even if the medicine is temporarily stopped), and for at least one month after you stop taking the medicine. The most effective forms of birth control are hormone birth control pills, patches, shots, vaginal rings, or implants, an IUD, or a vasectomy (for men). One of these forms of birth control should be combined with a condom, a diaphragm, or a cervical cap. If you think you have become pregnant while using this medicine, tell your doctor right away.
Do not take other medicines without checking first with your doctor . This includes vitamins, herbal products, prescription or nonprescription (over-the-counter [OTC]) medicines. Some of these medicines or nutritional supplements (e.g., St. John`s wort) may make your birth control pills not work.
During the first 3 weeks you are taking isotretinoin, your skin may become irritated. Also, your acne may seem to get worse before it gets better. Check with your doctor if your skin condition does not improve within 1 to 2 months after starting this medicine or at any time your skin irritation becomes severe . Full improvement continues after you stop taking isotretinoin and may take up to 6 months. Your doctor can help you choose the right skin products to reduce skin dryness and irritation.
Do not donate blood to a blood bank while you are using isotretinoin or for 30 days after you stop taking it. This is to prevent the possibility of a pregnant patient receiving the blood containing the medicine.
In some patients, isotretinoin may cause a decrease in night vision . This problem may occur suddenly. If it does occur, do not drive, use machines, or do anything else that could be dangerous if you are not able to see well . Also, check with your doctor .
Isotretinoin may cause dryness of the eyes. Therefore, if you wear contact lenses, your eyes may be more sensitive to them during the time you are taking isotretinoin and for up to about 2 weeks after you stop taking it. To help relieve dryness of the eyes, check with your doctor about using an eye-lubricating solution, such as artificial tears. If eye inflammation occurs, check with your doctor .
Isotretinoin may cause dryness of the mouth and nose. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
Avoid overexposing your skin to sunlight, wind, or cold weather. Your skin will be more prone to sunburn, dryness, or irritation, especially during the first 2 or 3 weeks of treatment . However, you should not stop taking this medicine unless the skin irritation becomes too severe . Do not use a sunlamp or tanning beds.
To help isotretinoin work properly, regularly use sunscreen or sunblocking lotions with a sun protection factor (SPF) of at least 15. Also, wear protective clothing and hats.
Isotretinoin may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed . If you or your caregiver notice any of these side effects, check with you doctor right away.
Isotretinoin may cause bone or muscle problems, including joint pain, muscle pain or stiffness, or difficulty moving . You may get hurt more easily during rough sports. You may heal more slowly. If this medicine is for your child, tell the doctor if you think your child is not growing properly.
Do not take vitamin A or any vitamin supplement containing vitamin A while taking this medicine, unless otherwise directed by your doctor . To do so may increase the chance of side effects.
Importance of not removing hair by wax epilation while taking isotretinoin and for 6 months after stopping isotretinoin. Isotretinoin can increase your chance of scarring from wax epilation.
Importance of not having any cosmetic procedures to smooth your skin (e.g., dermabrasion, laser) while taking isotretinoin and for 6 months after stopping isotretinoin. Isotretinoin can increase your chance of scarring from these cosmetic procedures.
For diabetic patients:
Pancreatitis may occur while you are using this medicine. Tell your doctor right away if you have sudden and severe stomach pain, chills, constipation, nausea, vomiting, fever, or lightheadedness.
Isotretinoin may cause some people to have hearing problems within a few weeks after they start taking it. Stop using this medicine and check with your doctor right away if you have continuing ringing or buzzing or other unexplained noise in the ears or hearing loss .
Liver problems may occur while you are using this medicine. Stop using this medicine and check with your doctor right away if you are having more than one of these symptoms: abdominal pain or tenderness; clay-colored stools; dark urine; decreased appetite; fever; headache; itching; loss of appetite; nausea and vomiting; skin rash; swelling of the feet or lower legs; unusual tiredness or weakness; or yellow eyes or skin .
Stop using this medicine and tell your doctor right away if you have an abdominal or stomach pain, rectal bleeding, or severe diarrhea. These may be symptoms of a serious condition called inflammatory bowel disease.
This medicine lowers the number of some types of blood cells in your body . Because of this, you may bleed or get infections more easily. To help with these problems, avoid being near people who are sick or have infections. Wash your hands often. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers.
