Please ask your questions related to Regrow?


Hello Dr.
Liao: A month ago, I went to the hospital's pulmonology department for a persistent cough due to a cold.
After the doctor's diagnosis, I was prescribed Regrow Sustained Release F.C.
Tablet 60mg as a cough suppressant, and I have been taking it for a month.
I found out online that this medication was removed from the market by the Ministry of Health and Welfare in 2016.
Therefore, I would like to ask Dr.
Liao if it is normal for the hospital to prescribe me this cough medication? Also, will taking it for a month have any effects? Thank you.

The use of Regrow cough medicine, specifically Regrow Sustained Release F.C. Tablet 60mg, raises significant concerns, especially considering that it was discontinued by the Ministry of Health and Welfare in 2016. When a medication is withdrawn from the market, it typically indicates that there were safety concerns, efficacy issues, or adverse effects that warranted such action. Therefore, it is crucial to understand the implications of using a medication that is no longer approved for use.

First and foremost, if you have been prescribed Regrow despite its discontinuation, it is essential to consult with your healthcare provider immediately. The prescribing physician may not have been aware of the drug's status, or there may have been a misunderstanding regarding its availability. It is not uncommon for healthcare providers to rely on outdated information, especially if they are not regularly updated on the latest drug approvals and withdrawals.

Regarding the potential effects of using Regrow for a month, several factors need to be considered. The primary concern is the possibility of adverse effects. Medications that have been discontinued may have been found to cause serious side effects that could pose risks to patients. These can include allergic reactions, gastrointestinal issues, or even more severe complications depending on the drug's mechanism of action and the patient's individual health profile.

If you have been taking Regrow for a month, it is advisable to monitor for any unusual symptoms or side effects. Common side effects of cough medications can include drowsiness, dizziness, nausea, and gastrointestinal disturbances. However, given the drug's discontinued status, there may be unknown risks associated with prolonged use. If you experience any concerning symptoms, such as difficulty breathing, swelling, or severe gastrointestinal distress, seek medical attention immediately.

Additionally, consider the underlying cause of your persistent cough. If it was due to a viral infection, such as a cold or flu, the cough may resolve on its own without the need for medication. Persistent coughs can also be a sign of other conditions, such as allergies, asthma, or even more serious respiratory issues. Therefore, it is essential to have a thorough evaluation to determine the underlying cause of your symptoms and to receive appropriate treatment.

In conclusion, using Regrow cough medicine after its discontinuation is not advisable without further consultation with a healthcare professional. The potential risks associated with its use, especially after being off the market for several years, could outweigh any benefits. It is crucial to prioritize your health and safety by discussing alternative treatment options with your doctor. They can provide you with safer, approved medications that can effectively manage your cough and address any underlying health issues. Always ensure that you are informed about the medications you are taking and their current status in the medical community.
