Drug Information
11 reviews for Serpina
Serpina is a herbal supplement made from Indian snakeroot (Rauwolfia serpentina). It is traditionally used to support healthy blood pressure and calmness.
Rauwolfia naturally contains reserpine, a real medicine that lowers blood pressure. This means Serpina can have strong effects and side effects like a medicine. Only use it with your doctor's knowledge.
What is it used for?
- Traditionally used to help lower blood pressure
- Traditionally used for calmness and sleep
How does it work?
Reserpine in Rauwolfia reduces certain nerve chemicals (such as noradrenaline) that tighten blood vessels, which lowers blood pressure and heart rate.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- This is a herbal supplement, not a licensed medicine. Its claims have not been checked in the same way as medicines, and scientific evidence for it is limited.
- Do not use it instead of medicine your doctor has prescribed. Do not stop your prescribed medicines without talking to your doctor.
- "Natural" does not always mean safe. Herbs can cause side effects and can interact with medicines.
- Talk to your doctor before using it if you are pregnant, trying to get pregnant or breastfeeding, have a long-term illness, or are having surgery.
- Not for children unless a doctor says so.
- Read the ingredient list on the pack carefully, especially if you have allergies.
- Do not take it if you have ever had depression. Reserpine can cause serious depression, even months after starting.
- Do not take it if you have a stomach ulcer, ulcerative colitis, or are having electroconvulsive therapy (ECT).
- Do not take it with antidepressants (especially MAOIs), other blood pressure medicines, or digoxin without your doctor's advice.
- Do not take it if you are pregnant or breastfeeding.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Serpina can cause side effects, but not everybody gets them.
Common side effects
- Mild stomach upset, wind or loose stools
- Feeling sick
- Stuffy nose
- Drowsiness or tiredness
- Dizziness or low blood pressure
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Signs of an allergic reaction, such as a rash, swelling of the face or lips, or trouble breathing
- Yellowing of the skin or eyes, dark urine or pale stools (a rare liver reaction to some herbs)
- Any new or worrying symptom after starting it
- Feeling very low, hopeless or having thoughts of self-harm
- Nightmares or severe mood changes
- Black stools or vomiting blood
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Only use it if your doctor agrees. Follow the dose on the pack.
- Swallow with water.
- Have your blood pressure checked regularly.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Do not take a double dose.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
