Medications for Parturients


Hello Dr.
Zheng, I traveled to Japan for my honeymoon for 5 days before February 10.
After returning, my mild cold turned into a severe one (with symptoms including severe sore throat, nasal congestion, continuous runny nose, cough, dizziness, and overall fatigue, etc.).
However, since I plan to conceive naturally, I have been avoiding contraception.
Considering that my honeymoon coincided with my ovulation week, I had limited opportunities for intercourse due to a packed schedule.
I'm worried about the possibility of being pregnant.
In this uncertain situation, can I take cold medication, or should I refrain from doing so? Some people have advised me to be cautious with medication until after confirming pregnancy, but textbooks state that it's best to avoid medication during the "first trimester." Does this first trimester include the uncertainty of this situation? I've been bedridden for two days and am still suffering from a severe cold, and I'm concerned about not being able to work, so I want to take the medications prescribed by my ENT doctor (Amoxicillin 500mg tid; Voren 50mg bid; Zyrtec 10mg hs; Colin sol.n 120ml tid; A.M.D tid).
However, the ENT doctor advised me not to take them until I'm sure I'm not pregnant...
-__- Oh, if that's the case, I might have to wait another two to three weeks...???? Additionally, before my honeymoon, my cervical smear showed signs of inflammation, and a culture revealed some bacterial infection.
My gynecologist prescribed Fastin suppositories, B.B.
(Clindamycin), and Amoxicillin for treatment.
Can I still safely use these medications now?

Dr. Li Guanghan reply Obstetrics and Gynecology


Hello: Generally, medications can affect the fetus during weeks 6 to 8 of pregnancy, so you should try to recover from your cold before March 10.
Your cold medications VOREN and COLIN should not be used, and CLINDAMYCIN is also contraindicated.
You can use PANADOL as a substitute for VOREN and MEDICON-A as a substitute for COLIN.
Additionally, make sure to drink plenty of warm water and get enough sleep; you will surely recover soon! Sincerely, Dr.

When it comes to taking cold medicine while uncertain about pregnancy, it is essential to approach the situation with caution. The early weeks of pregnancy, particularly the first trimester, are critical for fetal development, and many medications can pose risks during this time.
If you suspect you might be pregnant, the best course of action is to wait until you can confirm your pregnancy through a home pregnancy test or a visit to your healthcare provider. This is because certain medications can have teratogenic effects, meaning they can cause developmental issues in the fetus if taken during the early stages of pregnancy.

In your case, you mentioned experiencing significant cold symptoms, including a sore throat, nasal congestion, and fatigue. While it is understandable that you want to alleviate these symptoms, it is crucial to consider the medications you are contemplating taking.
The medications you listed, such as Amoxicillin, Voren, Zyrtec, and Colin, have varying safety profiles during pregnancy. Amoxicillin is generally considered safe for use during pregnancy, as it is a penicillin antibiotic that has been used for many years without significant adverse effects on fetal development. However, Voren (which contains diclofenac) is a non-steroidal anti-inflammatory drug (NSAID) that is typically advised against during pregnancy, especially in the third trimester, due to potential risks to the fetus and complications during labor.

Zyrtec (cetirizine) is an antihistamine that is often used for allergy relief and is considered relatively safe during pregnancy, but it is always best to consult with your healthcare provider before taking any medication. Colin, which is likely a cough syrup or expectorant, may also have ingredients that are not recommended during pregnancy.

Given your uncertainty about your pregnancy status, it is wise to err on the side of caution. If you are feeling very unwell, consider non-pharmacological approaches first, such as staying hydrated, resting, and using saline nasal sprays or steam inhalation to relieve congestion. If your symptoms persist or worsen, it is advisable to consult with a healthcare provider who can guide you on safe treatment options based on your specific situation.

Additionally, regarding the medications prescribed for your previous cervical infection, Clindamycin is generally considered safe during pregnancy, but again, it is essential to discuss this with your healthcare provider to ensure that it is appropriate for your current condition.

In summary, while it is tempting to take medication to relieve cold symptoms, it is crucial to confirm your pregnancy status first and consult with a healthcare provider about the safety of any medications you are considering. Prioritize non-drug interventions when possible, and seek professional guidance to ensure the best outcomes for both you and any potential pregnancy.
