Planning a pregnancy is one of the most important health decisions you’ll ever make. Yet, many women unknowingly continue medicines and supplements that can quietly affect fertility, egg quality, or early fetal development—often before pregnancy is even confirmed.
If you’re searching for medicines to avoid when trying to conceive, supplements to stop taking before pregnancy, or wondering “Can I take ibuprofen while trying to get pregnant?”—this medically reviewed, future-ready guide is for you.
Why What You Take Before Pregnancy Matters More Than You Think
Most birth defects and implantation issues occur in the first 2–4 weeks after conception, often before a missed period. This makes the preconception window critical.
Certain drugs are:
- Teratogenic (can cause birth defects)
- Hormone-disrupting
- Ovulation-suppressing
- Egg-quality damaging
That’s why doctors increasingly recommend a preconception detox from harmful medications at least 3 months before trying.
Medicines to Avoid When Trying to Conceive (2026 Updated List)
1. Painkillers & Anti-Inflammatories (NSAIDs)
High-intent search: Can I take ibuprofen while trying to get pregnant?
Avoid:
- Ibuprofen
- Diclofenac
- Naproxen
Why: These drugs may delay or block ovulation by interfering with prostaglandins.
Safer alternative:
- Paracetamol (only if necessary and short-term)
2. Retinoids & Vitamin A Derivatives
Keyword focus: Retinoids and pregnancy planning safety
Avoid:
- Isotretinoin
- Acitretin

3. Hormonal & Fertility-Affecting Medications
Avoid or review with doctor:

- Anti-androgen medications
- Some thyroid dose adjustments
Why: They can disrupt implantation, cycle regularity, or hormone balance.

Some antidepressants, mood stabilizers, and anti-seizure drugs need pre-pregnancy switching, not sudden stopping.
Never stop abruptly—this must be doctor-guided.
5. Antibiotics & Antifungals to Reconsider
Avoid when possible:
- Tetracyclines
- Fluoroquinolones
Why: These can affect embryonic bone and tissue development.
