Papaverine
About Papaverine
Papaverine is a prescription injection used to relax smooth muscles and widen blood vessels. It is primarily prescribed to treat spasms of the blood vessels, particularly in the brain, heart, or limbs, as well as spasms in organs like the stomach, gallbladder, or kidneys. By improving blood flow and relaxing tight muscles, this medicine helps relieve severe pain and cramping.
Since Papaverine is given as an injection, it is typically injected as needed for sudden symptoms or on a regular schedule determined by your doctor. It can be injected without regard to meals, but staying well-hydrated is highly recommended during your treatment. Making simple lifestyle adjustments, such as reducing salt intake and avoiding sudden temperature changes, can further support healthy blood flow.
While using Papaverine, you may experience mild side effects like flushing, sweating, mild headache, or stomach discomfort. If you experience serious symptoms, such as an irregular heartbeat, yellowing of your skin or eyes, or signs of liver damage, contact your doctor immediately.
Before starting treatment with Papaverine, tell your healthcare provider if you have a history of glaucoma, heart block, or liver problems. Do not take this if you have a complete heart block or severe liver damage.
Avoid drinking alcohol while receiving Papaverine, as it can increase drowsiness and worsen dizziness. It is also important to talk to your doctor or pharmacist if you are pregnant, breastfeeding, or an older adult, to ensure this injection is safe for your specific situation.
Do not use Papaverine if you have complete heart block, severe liver impairment or severe liver disease, or a known hypersensitivity to Papaverine or any component of the injection. Use with caution if you have glaucoma and ask your doctor before use.

Habit Forming
Diet & Lifestyle Advise
- Stay well-hydrated: Drink plenty of water to help support healthy circulation and ease the passage of kidney or gallbladder stones if you are using this medicine for organ spasms.
- Avoid sudden temperature changes: If you suffer from blood vessel spasms in your limbs, avoid sudden exposure to cold air or cold water, which can trigger vessel constriction.
- Limit sodium intake: Consuming less salt can help maintain healthy blood pressure and reduce the workload on your cardiovascular system.
- Avoid smoking: Nicotine causes blood vessels to constrict, directly opposing the beneficial widening effects of Papaverine.
Special Advise
Papaverine might alter liver function test results. Inform the person doing the tests that you are on treatment with Papaverine.
Regular liver function tests and blood tests are advised for people on chronic treatment with Papaverine.
If you are due to have any surgery, including dental surgery, inform the doctor/dentist that you are on treatment with Papaverine.
Patients Concern
Disease/Condition Glossary
Smooth muscle spasms: A muscle spasm is the sudden involuntary contractions of the muscle which can be painful and uncomfortable. When the nerve impulses that control the muscle movements are damaged or interrupted, it could lead to muscle spasms. Symptoms include muscle tightness, joint stiffness, unusual posture, difficulty in moving, and pain in affected muscles and joints.
Circulatory problems: The circulatory system is responsible for sending blood, oxygen and nutrients to various body parts. When blood flow to any specific body part is reduced, it could lead to poor circulation. Symptoms include numbness, tingling sensation, pain, muscle cramps, and throbbing or stinging pain in limbs.
Peripheral vascular disease: It is a blood circulation disorder that causes the blood vessels outside the brain and heart to narrow and block. The narrowed blood vessels cause reduced blood flow. It could occur due to the deposition of fat and calcium on the walls of the arteries. Symptoms include pain in the leg, especially while walking.
Erectile dysfunction: It is the inability to keep a hard and erect penis suitable for sexual intercourse. It could be a sign of physical or psychological conditions such as fear of sexual failure, anxiety, depression, low self-esteem, or stress. Certain health-related factors such as smoking, drinking, being overweight, being physically inactive, and having high blood pressure also contribute to erectile dysfunction. Symptoms include difficulty in getting an erection, decreased sexual desire, and difficulty in maintaining the erection during intercourse.
FAQs

Papaverine is a non-specific, direct-acting smooth muscle relaxant causing a vasodilating effect on the blood vessels and other smooth muscle systems. Papaverine exerts a spasmolytic effect by relaxing the smooth muscles of the gastrointestinal, bronchial, urinary tract, and biliary smooth muscles. Thereby, helps in treating muscle spasms.
Postural hypotension could be a side-effect of Papaverine. Postural hypotension is a sudden lowering in blood pressure leading to dizziness on standing. If you experience this, do not try to stand up suddenly or start walking; instead, lie down and get up slowly only when you feel better. People on treatment with Papaverine are advised to regularly monitor their blood pressure levels to avoid such unpleasant events.
