Precautions
It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to receive it.
Serious muscle reactions have occurred within hours to weeks after receiving this medicine. If you start to have muscle weakness, loss of bladder control, or trouble with swallowing, talking, or breathing, call your doctor right away. In some patients, these problems could be life-threatening and may require an immediate treatment in a hospital or clinic.
This medicine may make your muscles weak and cause vision problems (such as bleeding inside the eye). Avoid driving, using machines, or doing anything else that could be dangerous if you feel weak or are not able to see well.
This medicine may reduce blinking of the eye which can lead to an increased risk of eye problems (such as corneal exposure and ulcers). Tell your doctor right away if you have a reduced blinking of the eye.
This medicine may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash; itching; hoarseness; trouble breathing; trouble swallowing; or any swelling of your hands, face, or mouth while you are using this medicine.
After you have received this medicine and your vision or muscle spasms are better, you may find that you are a lot more active than you were before. You should slowly increase your activities to allow time for your body to get stronger. Also, before you start an exercise program, check with your doctor.
This medicine may increase your chances of having bronchitis or upper respiratory tract infections when given for upper limb spasticity. Tell your doctor right away if you have trouble breathing, sneezing, sore throat, coughing, or fever.
This medicine may cause a condition called autonomic dysreflexia in patients with nervous system disorders (such as spinal cord injury). It can be a life-threatening condition and requires immediate medical attention. Call your doctor right away if you have headache; increased sweating; slow heartbeat; warmth or redness in your face, neck, or arm; or have problems in urinating while using this medicine.
One part of this medicine is made from donated human blood. Some human blood products have transmitted certain viruses to people who have received them. The risk of getting a virus from medicines made of human blood has been greatly reduced in recent years. This is the result of required testing of human donors for certain viruses, and required testing during the manufacture of these medicines. Although the risk is low, talk with your doctor if you have concerns.
