4 Precautions To Take
Before using Vesanoid, there are some precautions you must take. Your doctor should check your progress at regular visits to make sure that the medicine is working properly and to check for unwanted effects.
Tretinoin causes fever, headache, tiredness, and weakness in most people who take it. It is very important that you continue taking the medicine even if it makes you feel ill. Your health care professional may be able to suggest ways to relieve some of these effects.
However, if you develop a very severe headache or a headache that occurs together with nausea, vomiting, or vision problems, check with your doctor right away.
Tretinoin sometimes causes a severe reaction that affects the lungs at first, but can later spread to other parts of the body. Signs of this reaction include breathing problems, bone pain, chest pain, and fever. Check with your doctor right away if any of these effects occur during treatment.
Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine.
Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them.
Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
