Nausea, vomiting, constipation, dizziness, drowsiness, weakness, unusual sweating, headache, and dry mouth may occur. If these effects persist or worsen, notify your doctor promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
You may also develop a sudden drop in blood pressure, which can cause dizziness, nausea, and fainting. This is more likely when you are first starting the medication or when your dose is increased, or when you get up suddenly. To lower your risk, get up slowly from a sitting or lying position.
This medication may also raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.
Tell your doctor right away if you have any serious side effects, including: difficulty moving or walking, mental/mood changes (e.g., confusion, depression, hallucinations, memory problems, trouble sleeping), muscle cramps/spasms, decreased sexual ability, unusual strong urges (such as increased gambling, increased sexual urges), swelling of the ankles/feet, chest pain, unusually fast/slow/irregular heartbeat, vision changes.
Some people taking ropinirole have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with ropinirole even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
