Can You Take Benadryl With Minocycline?

Quick Answer

Minocycline capsules and Benadryl (diphenhydramine) are not known to interact. However, both medications can potentially cause drowsiness and fatigue, so there may be additive sedative effects if taken together.

As always, it's a good idea to consult with your healthcare provider or pharmacist for personalized advice.

Detailed Answer

Minocycline capsules, an antibiotic commonly used to treat bacterial infections, and Benadryl (diphenhydramine), an antihistamine often used for allergies and sleep aid, are not known to have any significant interactions.

However, it's important to note that both medications have the potential to cause drowsiness and fatigue as side effects.

Benadryl is well-known to cause sedation, which is why it's often used as a nighttime sleep aid.

Minocycline, while not generally associated with causing sedation, can cause it. In fact, the prescribing information for the drug notes that approximately 9% of individuals taking the drug experience fatigue.

So, overall, combining minocycline and Benadryl could increase the overall sedative effect of each, making you feel sleepier or more tired.

As a precaution, it's advisable to be cautious when taking them together, especially if you plan to engage in activities that require alertness or driving.

It's important to understand that the sedative effect may vary among individuals, and certain factors such as dose, frequency, and individual sensitivity can impact how the two medications interact in each person.

Minocycline Injection Has a Greater Sedative Risk

It's important to point out that injectable minocycline contains magnesium sulfate heptahydrate, which can have central nervous system (CNS) depressant effects.

Concurrent use with other CNS depressants, like sedating H1-blockers such as Benadryl, may result in additive central-depressant effects. However, this caution is specific to the injectable form, and it does not apply to minocycline capsules (which doesn't contain magnesium sulfate heptahydrate).
