Usage
- Bromelain is primarily prescribed for reducing inflammation and swelling, particularly after surgery or injury. It is also used for osteoarthritis, sinusitis, and improving digestion. Some studies suggest its potential use for muscle soreness, burns, and other conditions, though more research is needed.
- Pharmacological Classification: Proteolytic enzyme, anti-inflammatory agent.
- Mechanism of Action: Bromelain’s primary mechanism involves breaking down proteins that contribute to inflammation and pain. It also appears to affect the production of certain substances in the body that fight pain and swelling.
Alternate Names
- Ananas comosus, pineapple enzyme, pineapple extract.
- Brand names vary depending on the manufacturer.
How It Works
- Pharmacodynamics: Bromelain exerts its effects through anti-inflammatory and analgesic actions, primarily by decreasing bradykinin levels and modulating prostaglandin synthesis. It may also enhance the absorption of certain medications like antibiotics.
- Pharmacokinetics: Orally administered bromelain exhibits limited systemic absorption. It is metabolized in the gastrointestinal tract. The exact elimination pathway is not fully elucidated, but it’s believed to be primarily through renal excretion.
- Mode of Action: Bromelain’s proteolytic activity appears to be central to its anti-inflammatory and analgesic actions. It breaks down proteins involved in the inflammatory cascade.
Dosage
Standard Dosage
Adults:
- 80-400 mg, two to three times daily. Some studies suggest higher doses (up to 2000 mg/day), but this should be under the guidance of a healthcare provider.
- It can be administered with or without food. For digestion, it’s typically taken with meals. For inflammation, it may be more effective on an empty stomach.
Children:
- Limited information is available on pediatric dosing. Some sources suggest half the adult dose for children aged 6-12 years, but consultation with a pediatrician is crucial.
- Pediatric safety needs further investigation.
Special Cases:
- Elderly Patients: Dosage adjustments may be required based on individual health status and organ function.
- Patients with Renal Impairment: Dose modifications may be necessary depending on the degree of impairment.
- Patients with Hepatic Dysfunction: Careful monitoring and potential dose adjustments are advised.
- Patients with Comorbid Conditions: Individualized dosing is crucial, considering potential interactions with other medications.
Clinical Use Cases
- Bromelain’s clinical use in settings like intubation, surgical procedures, mechanical ventilation, ICU use, and emergency situations is not well-established and lacks sufficient clinical evidence.
Dosage Adjustments
Dose modification is based on patient factors such as age, renal/hepatic function, and concurrent medications, particularly anticoagulants and antibiotics.
Side Effects
Common Side Effects
Diarrhea, nausea, vomiting, heavier menstrual bleeding.
Rare but Serious Side Effects
Allergic reactions (including anaphylaxis in those sensitive to pineapple, latex, certain pollens, and other substances).
Long-Term Effects
Limited information is available on long-term effects.
Adverse Drug Reactions (ADR)
Severe allergic reactions requiring immediate medical attention.
Contraindications
- Hypersensitivity to bromelain or pineapple.

- Sedatives (potential for increased sedative effects).
Pregnancy and Breastfeeding
- Pregnancy Safety Category: Not established.
- Avoid use during pregnancy due to potential for abnormal bleeding and miscarriage.
- Potential for excretion in breast milk and interference with lactation. Avoid during breastfeeding.

FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Bromelain?
A: The typical adult dose is 80-400 mg, taken two to three times a day. However, dosage can vary depending on the individual and the condition being treated. Consult a healthcare professional for personalized advice.
Q2: How should Bromelain be taken?
A: Bromelain can be taken with or without food. For digestive support, taking it with meals is usually recommended. For anti-inflammatory effects, taking it on an empty stomach might enhance its absorption.
Q3: What are the common side effects of Bromelain?
A: Common side effects include diarrhea, nausea, vomiting, and increased menstrual bleeding.
Q4: Who should not take Bromelain?
A: Individuals with hypersensitivity to bromelain or pineapple, pregnant or breastfeeding women, those with bleeding disorders, or those undergoing surgery should avoid bromelain.
Q5: Does Bromelain interact with any medications?
A: Yes, bromelain can interact with blood thinners, certain antibiotics (like tetracyclines), and sedatives. Consult your doctor about potential interactions with your current medications.
Q6: Can Bromelain be used during pregnancy?
A: No, bromelain is contraindicated during pregnancy due to the risk of miscarriage.
Q7: Is Bromelain safe for children?
A: Information on pediatric use is limited. Consult a pediatrician before administering bromelain to children.
Q8: How does Bromelain reduce inflammation?
A: Bromelain’s proteolytic activity helps break down inflammatory proteins, decreasing swelling and pain.
Q9: Can I get enough Bromelain by eating pineapple?
A: While pineapple contains bromelain, the concentration in the fruit is unlikely to be therapeutically effective. Supplements offer a more standardized and concentrated dose.
