Do certain drugs increase the level of ALT?

Question

Hi doctor,

I had a liver function blood test on four months ago, where all readings were normal except for serum ALT, which was 49. One week prior to this test, I had taken four tablets of Naproxen. This caused an itching reaction, so I stopped it. It was assumed that either the Naproxen or antibiotics I had taken a month earlier (Metronidazole and Azithromycin) might have caused the elevated ALT.

I retested on last month after finishing another course of medications, I was on the following:

One week of Metronidazole.
Two weeks of Doxycycline.
A single dose of Fluconazole, followed by one week of Fluconazole.

Additionally, I took Diazepam as a single dose on two occasions.

The last month test showed a significant ALT rise to 109.

I had a liver scan, which was normal. I also had a repeat scan today, and the sonographer mentioned there was nothing concerning.

I have been taking Pregnacare pregnancy vitamins, which I have now stopped, as I am not convinced they are not contributing to my elevated ALT.

Why is my ALT elevated?
Could it be linked to the medications I have taken or other factors?
Could this be hepatitis or autoimmune hepatitis?
Is this a sign of liver disease?
Can I expect to recover fully and return to normal levels, or could this be permanent liver damage or a lifelong condition?

I am not on any regular medications and would appreciate your insights, as I am quite worried about my situation.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have read your query and can understand your concern.

After carefully reviewing your history and laboratory results, it appears that your elevated ALT (alanine aminotransferase) is likely due to a mild acute liver injury. Such injuries can occur as a result of certain medications or, less commonly, viral infections.

In your case, the most probable cause seems to be Fluconazole, which is known to affect liver enzymes in some individuals.

Key points:

Reversibility: This condition is completely reversible. Your ALT levels should return to baseline within a few weeks.
Follow-Up: A repeat liver function test in two weeks is recommended to monitor progress.
No serious concern: Your liver scans and the absence of other symptoms suggest that there is no evidence of any serious liver disease, including autoimmune hepatitis or chronic liver disease.
Precautions: It is advisable to avoid Paracetamol and any potentially liver-straining medications at this time.

You can rest assured that there is nothing significant or worrisome regarding your liver health based on the current findings.

I hope this provides clarity on your concerns.

Thank you.

Yes, nothing to worry about. It is not a permanent issue; it will disappear in two weeks. Yes, you can proceed with your pregnancy planning. It is not going to affect your pregnancy or baby.

Thank you.

Hi,

Welcome back to icliniq.com.

No, it will not affect you while pregnant or non-pregnant.
Yes, any acute injury to the liver causing elevated ALT levels is referred to as acute hepatitis.
There is nothing else to avoid except paracetamol and alcohol.
You will be able to take paracetamol once your levels return to normal.
You should not be concerned.

Thank you.

Hi,

Acute Hepatitis is a temporary condition that returns to 100% Normal. Do not worry about the term Hepatitis.

Thank you.
