Side effects of Panadol?


The medication you mentioned, which is a yellow oval pill marked with "IB4," is likely a type of pain reliever.

However, experiencing a rapid heartbeat and feeling faint can be concerning, especially if you are taking a higher dosage than recommended.

Please do not adjust your dosage or stop taking the medication without professional guidance.

Dear: The discussion of the side effects of a medication is predicated on knowing its active ingredients.
Based on your description, I have found a similar medication; please refer to the attached image to confirm whether it matches the medication you have.
The active ingredient of this medication is Ibuprofen 400mg, which is used for anti-inflammatory and analgesic purposes.
The maximum recommended daily dosage is 1200mg, and it is generally advised to take the lowest effective dose for the shortest duration (not exceeding 10 days) to avoid related side effects.

The most common side effects of Ibuprofen include gastrointestinal discomfort, skin rashes, and edema, while rare but serious side effects will not be discussed here.
Common side effects typically appear shortly after taking the medication; if you have been taking Ibuprofen for several days without experiencing these symptoms, it indicates that Ibuprofen is suitable for you.

Regarding cardiovascular side effects, Ibuprofen may cause changes in blood pressure, including both increases and decreases (the former being more common).
There are no direct reports of it causing an increased heart rate, but it is advisable to monitor your blood pressure to see if any physiological feedback from blood pressure changes results in an increased heart rate.

Wishing you all the best! Stay healthy and happy!

More Info


When it comes to pain relievers, understanding their side effects is crucial for safe and effective use. The medication you mentioned, which is identified as "IB4," likely refers to a formulation containing ibuprofen, a common nonsteroidal anti-inflammatory drug (NSAID). Ibuprofen is widely used to alleviate pain, reduce inflammation, and lower fever. However, like all medications, it can have side effects, especially when taken in higher doses or for extended periods.


Common Side Effects of Ibuprofen
1. Gastrointestinal Issues: One of the most common side effects of ibuprofen is gastrointestinal discomfort. This can include symptoms such as stomach pain, heartburn, nausea, vomiting, and even ulcers or gastrointestinal bleeding, particularly if taken on an empty stomach or in high doses.

2. Cardiovascular Effects: Ibuprofen can potentially increase blood pressure and may pose risks for individuals with pre-existing heart conditions. It can also lead to fluid retention, which might exacerbate heart failure in susceptible individuals.

3. Kidney Function: Long-term use of ibuprofen can affect kidney function, leading to conditions such as acute kidney injury, especially in individuals who are dehydrated or have pre-existing kidney issues.

4. Allergic Reactions: Some individuals may experience allergic reactions to ibuprofen, which can manifest as rashes, itching, or more severe reactions like anaphylaxis.

5. Central Nervous System Effects: Although less common, some people may experience dizziness, headaches, or even confusion. Your experience of a rapid heartbeat and feeling faint could potentially be related to the medication, especially if you are taking it in higher doses than recommended.


Recommendations
Given that you are taking 9 pills a day, which exceeds the typical maximum recommended dose for ibuprofen (generally 1200-2400 mg per day for adults, depending on the condition being treated), it is essential to reassess your dosage. High doses can increase the risk of serious side effects, including those affecting the heart and gastrointestinal tract.

1. Consult Your Doctor: It is crucial to discuss your symptoms, especially the rapid heartbeat and feelings of faintness, with your healthcare provider. They can evaluate whether these symptoms are related to ibuprofen or if there might be another underlying issue.

2. Monitor Your Dosage: Ensure you are not exceeding the recommended dosage. If you feel that the pain relief is insufficient, your doctor may suggest alternative medications or therapies that can provide relief without the associated risks of high-dose ibuprofen.

3. Consider Alternatives: If ibuprofen is causing side effects, your doctor may recommend other pain relief options, such as acetaminophen (Tylenol), which has a different side effect profile. However, it’s important to note that acetaminophen also has its own risks, particularly concerning liver health when taken in excess.

4. Lifestyle Adjustments: Alongside medication, consider non-pharmacological approaches to pain management, such as physical therapy, heat/cold therapy, or relaxation techniques, which can help alleviate pain without the risks associated with high-dose medications.


Conclusion
While ibuprofen can be effective for pain relief, it is essential to use it judiciously and be aware of potential side effects. If you are experiencing concerning symptoms like a rapid heartbeat and faintness, it is vital to consult with your healthcare provider promptly. They can help you determine the best course of action, including adjusting your medication regimen and exploring alternative pain management strategies. Always prioritize your health and safety when it comes to medication use.
