Raynaud's phenomenon (RP) is a condition resulting in a particular series of discolorations of the fingers and/or the toes after exposure to changes in temperature (cold or hot) or emotional events. Skin discoloration occurs because an abnormal spasm of the blood vessels causes a diminished blood supply to the local tissues. Initially, the digit(s) involved turn white because of the diminished blood supply. The digit(s) then turn blue because of prolonged lack of oxygen. Finally, the blood vessels reopen, causing a local "flushing" phenomenon, which turns the digit(s) red. This three-phase color sequence (white to blue to red), most often upon exposure to cold temperature, is characteristic of RP.
Raynaud's phenomenon most frequently affects women, especially in the second, third, or fourth decades of life. People can have Raynauds phenomenon alone or as a part of other rheumatic diseases. When it occurs alone...

Inderal (propranolol hydrochloride) is a beta-adrenergic receptor blocking agent that is used for control of hypertension. Inderal is available as a generic named propranolol. Common side effects of Inderal include GI effects (vomiting, diarrhea, and constipation), rash, tired, dizziness, and sleeping problems.
Inderal is available in strengths of 10, 20, 40, 60, and 80 mg tablets for oral administration. Doses are variable; tablets should be swallowed not chewed. Inderal may interact with a number of different drugs; use with other cardiac drugs may cause cardiomyopathy, congestive heart failure or heart attack. Severe side effects of Inderal may include slow and irregular heartbeat, hypotension, chest pain, short of breath, bleeding, swelling of hands or feet, bronchospasm, and glaucoma. Neonates whose mothers received propranolol at parturition have exhibited bradycardia, hypoglycemia and/or respiratory depression. Adequate facilities for monitoring these infants at birth should be available; breastfeeding women taking the drug should be cautioned about monitoring their infants as Inderal is excreted in breast milk. Some investigators have used Inderal in pediatric patients, but it is not approved for use in pediatric patients.
Our Inderal Drug Center provides a comprehensive view of available drug information as well as related drugs, user reviews, supplements, and diseases, and conditions.
