Do antihistamines pass through breast milk?

Antihistamines and Breast Milk: What You Need to Know
The question of whether antihistamines pass through breast milk is a significant concern for nursing mothers who may need relief from allergies or other conditions. Current research indicates that while antihistamines do enter breast milk, the amounts are generally minimal and considered safe for breastfeeding infants.
Minimal Transfer to Breast Milk
Studies have shown that both first-generation and second-generation antihistamines are secreted in breast milk, but in very small quantities. For instance, a systematic review highlighted that only minimal amounts of these medications are reported to be transferred to breast milk, which is reassuring for nursing mothers. Specifically, cetirizine, a commonly used second-generation antihistamine, has been found to have negligible effects on breastfed infants, with no adverse effects reported from its use.
Safety Profile
The safety profile of antihistamines during breastfeeding is generally positive. Most healthcare professionals agree that the benefits of treating allergic reactions or other conditions with antihistamines outweigh the potential risks associated with their minimal presence in breast milk. For example, while first-generation antihistamines may cause sedation, the amounts that pass into breast milk are unlikely to affect the infant significantly.
Moreover, the American Academy of Family Physicians emphasizes the importance of weighing the benefits of medication for the mother against the potential risks to the infant. This careful consideration is crucial, especially when the mother’s health is at stake.
Considerations for Use
While the data is reassuring, it is essential for breastfeeding mothers to consult with healthcare providers before starting any medication, including antihistamines. This is particularly important for those who may be taking larger doses or using these medications for extended periods, as higher doses could potentially lead to drowsiness in infants or affect milk supply.
In conclusion, while antihistamines do pass into breast milk, the amounts are minimal and generally safe for breastfeeding infants. Mothers should always seek medical advice to ensure the best outcomes for both themselves and their babies.

Can allergies be passed through breast milk?

Babies can develop allergies to foods that you are eating while you are breastfeeding. There are no recommendations to avoid any food while you are breastfeeding to prevent allergies.

Can I breastfeed after taking antihistamine?

There are relatively fewer data on the nonsedating second-generation antihistamines; however, published studies are reassuring. All antihistamines are considered safe to use during breastfeeding, as minimal amounts are excreted in the breast milk and would not cause any adverse effects on a breastfeeding infant.

What happens if I take antihistamines while breastfeeding?

There is conflicting data on the effect of antihistamines and breast milk production, and the evidence is very limited. Antihistamines, used at normal therapeutic doses are unlikely to affect breast milk production, especially where lactation is established, i.e. after 6-8 weeks postpartum.

What medications should be avoided while breastfeeding?

Common medicines that are not recommended when you’re breastfeeding include:

• codeine phosphate.
• decongestants that come as tablets, liquids or powders that you swallow.

• Amphetamines.
• Chemotherapy drugs.
• Chloramphenicol (an antibiotic)
• Radioactive substances used for diagnostic procedures.
• Illicit drugs such as , heroin, and phencyclidine (PCP)
• Medications that may suppress milk production.

Why is Zyrtec not recommended while breastfeeding?

However, caution is advised for cetirizine use while breastfeeding due to the theoretical risk of CNS depression based on limited human data and risk of decreased milk production.

How long until Benadryl is out of breast milk?

Also ask how long the medicine will be in your breast milk, so you can plan for future feedings or pumping. Hux says that 50 milligrams of Benadryl, which is usually the dose taken for an allergic reaction, is going to stay in your system for about eight hours or even a little longer.

Do histamines pass through breast milk?

Elevated levels of histamine have not been found in breast milk. During pregnancy, there is an increase in the production of the DAO enzyme in most placentas from week 12 of gestation to create a metabolic barrier and prevent excessive entry of histamine into the fetus.

Can I breastfeed if I took Benadryl?

Taking Benadryl occasionally during breastfeeding is safe. However, taking Benadryl regularly or in large doses may cause side effects in a child who is breastfed. It may also reduce your milk supply. Antihistamines that cause less sleepiness are usually preferred over oral Benadryl while breastfeeding.

Can I take antihistamines while breastfeeding?

Recommendation. The preferred choice of sedating antihistamine is chlorphenamine due to extensive experience of safe use. Hydroxyzine or promethazine can be used when breastfeeding with caution and close monitoring, if chlorphenamine is not suitable.
