"I got a cold during the stimulation or transplantation phase. Can I still take my medications?" This is a common question asked by Leilawa during their Q&A sessions. A cold itself isn't dangerous, but during IVF, extra caution is needed. This article provides guidelines based on different stages of the process. However, always consult your doctor before taking any medication.

1. General principle: Do not take medication without consulting a doctor.

Medication during the IVF process can be complex. Taking cold medicine on your own may interact with medications used for stimulation or maintaining the corpus luteum, or affect liver and kidney function. Therefore, the first step is to contact your doctor or hospital, rather than trying to treat the condition on your own.

2. During pregnancy preparation and stimulation phase

• For mild colds (slight runny nose, low fever), rest, stay hydrated, and use physical methods to reduce fever;
• Avoid medications that may affect blood pressure or blood flow, such as pseudoephedrine. Follow the advice of your doctor or pharmacist;
• If the fever persists or symptoms worsen, seek medical attention immediately. Do not try to endure the symptoms on your own.

3. Before and after egg retrieval

Egg retrieval is a surgical procedure, and having a cold may increase the risk of anesthesia complications and infections. If you have a severe cold before egg retrieval (especially if there's fever or cough), be sure to inform your doctor. The doctor will decide whether to delay the procedure. Do not hide this information from them.

4. After transplantation/first trimester of pregnancy

During this stage, the safety of medication is particularly important. Any medication, including traditional Chinese medicines or antipyretics, should be used under the guidance of a doctor. For minor discomfort, try natural remedies like rest and warm liquids.

5. Prevention is better than cure

• During IVF, avoid crowded places;
• Use masks and wash hands frequently;
• Maintain good sleep and nutrition to boost immunity.

6. Reminders from Leilawa

Cold itself generally doesn't directly affect embryos. But taking medications without proper guidance increases risks. It's best to leave decisions about whether to take medication to the doctor. That's the safest approach.
