Isoxsuprine Hydrochloride
About Isoxsuprine Hydrochloride
Isoxsuprine Hydrochloride is a medication primarily prescribed to improve blood circulation in patients who experience poor blood flow in their limbs, hands, and feet. It is commonly used to treat conditions that cause blood vessels to narrow, which can restrict the healthy flow of oxygen-rich blood throughout your body. By relaxing your blood vessels, this medicine helps ease symptoms like coldness, numbness, and cramping in your fingers, toes, and legs.
To get the best results, you must take Isoxsuprine Hydrochloride consistently and exactly at the times recommended by your doctor. You can take this tablet with or without food, though taking it with meals can help prevent a mild upset stomach. Making healthy daily choices, such as avoiding cold exposure and keeping your hands and feet warm, can also help improve your circulation while using this medicine.
While taking Isoxsuprine Hydrochloride, some people may experience mild side effects like dizziness, flushing, or a rapid heart rate. These symptoms are often temporary as your body adjusts, but you should contact your doctor immediately if you experience severe chest pain, extreme dizziness, or signs of a serious allergic reaction.
Do not take this if you have a history of bleeding disorders, have recently given birth, or have active bleeding from your arteries. If you have heart disease, glaucoma, or severe low blood pressure, you should talk to your doctor before starting this medicine to ensure it is safe for your specific condition.
This medicine can interact with other drugs, especially those used to treat high blood pressure, which can cause your blood pressure to drop too low and make you feel faint. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your doctor or pharmacist before starting treatment to discuss potential risks and benefits.

Patients Concern
Disease/Condition Glossary
Premature labour: It is also known as preterm labour which occurs due to contractions and relaxations of the uterus resulting in the opening of the cervix after week 20 and before week 37 of pregnancy. It can lead to premature birth and other risks to the baby.
Cerebrovascular insufficiency: It occurs when there is obstruction of one or more blood vessels (arteries) that supply blood to the brain. This obstruction leads to strokes or transient ischemic attacks (TIAs or 'mini-strokes').
Buerger's disease: It occurs commonly in the arms and legs where blood vessels get swollen, thereby preventing blood flow, causing clots to form. This leads to pain, tissue damage, and the formation of gangrene (death of body tissues).
Raynaud's phenomenon: It occurs due to blocked nerves resulting in discolouration of the fingers and/or the toes after exposure to extreme cold or hot temperatures conditions. Skin discolouration is a sign of a diminished blood supply to the local tissues.
FAQs
Isoxsuprine Hydrochloride belongs to a class of medication called 'vasodilators' (blood vessel relaxing agents) used to treat and prevent peripheral vascular diseases such as Raynaud's phenomenon, cerebral vascular insufficiency (poor blood flow to the brain), arteriosclerosis (hardening of the arteries), Buerger's disease (a condition that causes small and medium arteries and veins to constrict blood flow to the hands and feet) and other conditions involving poor blood flow in the blood vessels.
Isoxsuprine Hydrochloride acts by relaxing and widening blood vessels, thereby increasing the blood flow to the organs, muscles and blocked nerves of the body.
