Can I Take Stendra (Avanafil) While Pregnant?

Is Avanafil Safe to Take During Pregnancy?

The short answer is no, and this matters more than it might seem. Avanafil (Stendra) is not approved for use in women at all, which means there is no human safety data for pregnant women or developing babies. If you took it before knowing you were pregnant, the right move is to stop now and call your provider promptly, not to wait and see.

Avanafil is FDA-approved exclusively for adult men with erectile dysfunction. Its use during pregnancy is entirely off-label and unstudied in humans. No controlled trials have examined what this drug does to fetal development, placental function, or maternal health during pregnancy. Animal reproductive studies suggest some possible concern, but animal data does not reliably predict human outcomes.

What Drug Class Is Avanafil, and Why Does That Matter?

Avanafil belongs to a group of medications called PDE5 inhibitors (drugs that relax blood vessels by blocking a specific enzyme called phosphodiesterase-5). You may recognize other drugs in this class: sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra).

This class of drugs works by widening blood vessels and relaxing smooth muscle throughout the body. During pregnancy, that mechanism is a meaningful concern because it could theoretically affect placental blood flow or interfere with how a fetus's cardiovascular system develops.

Under the FDA's current labeling system, avanafil's label frankly states there is insufficient human data to assess risk in pregnancy. That is not a green light; it is an honest acknowledgment of a data gap that should be treated with caution.

Could Accidental Exposure Harm the Baby?

This is one of the most common concerns, and it deserves a careful answer. A single accidental dose taken before you knew you were pregnant is unlikely to cause a known catastrophic outcome, but that cannot be stated with complete certainty given the absence of human safety data.

The first trimester is the most critical window for fetal organ development, making any unverified medication exposure during this time worth a direct conversation with your OB-GYN or a maternal-fetal medicine specialist (a high-risk pregnancy expert).

The experience with sildenafil, the most closely studied PDE5 inhibitor, is worth knowing. The STRIDER trial, which tested sildenafil in pregnant women with fetal growth restriction, was halted early because of unexpected lung complications in newborns. That outcome raised a serious safety flag for the entire drug class during pregnancy, not just sildenafil specifically.

If you took avanafil before discovering your pregnancy, here is what to do:

• Write down the details. Note the dose, how many times you took it, and the approximate dates.
• Call your provider. Share those details so they can assess whether additional monitoring is needed.
• Do not take any more. Stop immediately and do not resume without explicit guidance from an OB-GYN.
• Consider reaching out to OTIS. The Organization of Teratology Information Specialists tracks medication exposures during pregnancy and can offer additional guidance.

How Do PDE5 Inhibitors Compare for Pregnancy Safety?

No PDE5 inhibitor has a clean safety record in pregnancy, but the level of available data varies across drugs in the class. The table below summarizes what is currently known.

The pattern is consistent: no PDE5 inhibitor is appropriate during pregnancy, and the one with the most pregnancy research came with a serious safety warning.

Are There Any Legitimate Reasons a Pregnant Woman Might Be Prescribed Avanafil?

No current clinical guideline or approved indication supports prescribing avanafil to a pregnant woman for any condition. Researchers have explored PDE5 inhibitors experimentally for conditions like preeclampsia (dangerously high blood pressure in pregnancy) and intrauterine growth restriction (when a baby is not growing as expected), but those studies used sildenafil under strict research protocols and produced concerning results.

Avanafil was not part of those investigations. There is simply no scenario in routine clinical practice where avanafil is the right choice for a pregnant patient.

If a provider suggests avanafil during pregnancy, it is entirely appropriate to ask why and to seek a second opinion from a maternal-fetal medicine specialist.

What Should You Do Next?

Because avanafil treats erectile dysfunction, a condition that by definition does not apply to pregnant women, most exposures during pregnancy happen by accident, usually because someone continued a prescription without realizing they were pregnant, or a partner's medication was mistakenly taken.

Regardless of how the exposure happened, the path forward is the same:

• Stop taking avanafil immediately.
• Contact your OB-GYN or a maternal-fetal medicine specialist to discuss exposure details and whether monitoring is warranted.
• Ask specifically about your first trimester timeline if that is when exposure occurred, since organ development is most active then.
• Avoid over-the-counter supplements marketed for circulation or sexual health during pregnancy. These are not proven safe and are not a substitute for medical guidance.

Doctronic, the first AI legally authorized to practice medicine, offers 24/7 consultations at low cost and can help you clarify next steps quickly. With a 99.2% treatment plan alignment with board-certified physicians, it is a practical bridge while you wait for an in-person appointment.

If you are managing a separate cardiovascular or blood pressure concern during pregnancy, your provider can recommend alternatives with established pregnancy safety records. The goal is never to leave a real medical need untreated; it is to make sure the treatment chosen is one that your provider can stand behind for both you and your baby.

Frequently Asked Questions

What happens if I accidentally took Stendra before knowing I was pregnant?

Try not to panic. Document the dose, timing, and frequency, then contact your OB-GYN promptly. A single early exposure is unlikely to cause known catastrophic harm, but your provider may recommend additional monitoring such as an early ultrasound.

Is avanafil the same as sildenafil, and does the pregnancy risk differ?

They are different drugs in the same PDE5 inhibitor class. Sildenafil has more pregnancy research, and some trials were halted due to neonatal lung complications. Avanafil has even less human data, making its pregnancy risk profile equally or more uncertain.

Can PDE5 inhibitors cause miscarriage or birth defects?

There is no confirmed human evidence linking PDE5 inhibitors to miscarriage or birth defects, but the data gap is large. Animal studies show some concern, and the sildenafil STRIDER trial raised serious neonatal safety flags, warranting caution across the entire drug class.

Are any erectile dysfunction medications safe to take during pregnancy?

Erectile dysfunction medications treat a condition that does not affect pregnant women. No ED drug has an approved or established-safe indication in pregnancy. If you have a separate cardiovascular or circulatory concern, ask your provider for pregnancy-approved alternatives.

Who should I call if I took avanafil during my first trimester?

Contact your OB-GYN or a maternal-fetal medicine specialist first. You can also reach OTIS (Organization of Teratology Information Specialists) for medication exposure guidance, or connect with a Doctronic physician for fast, affordable telehealth support while awaiting an in-person visit.

The Bottom Line

Avanafil has no approved use in women, no human pregnancy safety data, and no legitimate clinical reason to be prescribed during pregnancy. The unknown risk alone is reason enough to avoid it entirely. If you took avanafil before learning you were pregnant, stop immediately, document your exposure details, and connect with a licensed clinician as soon as possible. Doctronic, with over 22 million AI consultations and 24/7 availability, can connect you with a physician quickly and affordably while you arrange in-person follow-up care.
