Adrafinil and Alemtuzumab

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Alemtuzumab and Adrafinil in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Alemtuzumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Alemtuzumab is filed under 2 classifications — immunosuppressants, oral drugs. Adrafinil has documented interactions with 11 drug classes — the most serious being modafinil (provigil) (major), antihypertensive drugs (moderate) and cytochrome p450 1a2 (cyp1a2) substrates (moderate) — and none of Alemtuzumab’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Special populations

Adrafinil in Pregnancy & Breastfeeding

Pregnancy And Lactation Possibly Unsafe

When used orally. Adrafinil is a precursor to the stimulant prescription drug modafinil. Modafinil has been associated with reports of intrauterine growth restriction and spontaneous abortion. Also, animal studies show that developmental toxicity occurs with use of modafinil during pregnancy. Although modafinil, and possibly adrafinil, might have addictive potential, the potential for abuse is low. However, there have been anecdotal reports of withdrawal symptoms following use of adrafinil, alone or in combination with other products. Avoid using.

About Adrafinil

What is Adrafinil?

Adrafinil
  • Wakefulness and alertness
  • Fatigue
  • Focus and concentration
  • Cognitive enhancement (nootropic)
  • Daytime sleepiness

Adrafinil is a synthetic compound that the body converts into modafinil, a prescription wakefulness-promoting drug. It is sometimes sold as a nootropic supplement, but it is unregulated, carries real risks (especially to the liver), and is banned in some sports and countries. Talk with a doctor or pharmacist before using it.

Synthetic compound (not from a plant) · Capsules, tablets, powder

An interaction check asks whether these two react with each other — it does not ask whether Adrafinil is a good idea for someone in your situation. Here is what our Adrafinil record says about it on its own.

Adrafinil: dosing

There is no officially established or standardized supplement dose for adrafinil, and it is not approved as a dietary supplement by health authorities. Doses used historically as a prescription medicine were determined by doctors and are not the same as casual self-dosing.If a product is used, follow the directions on the label and do not exceed them. Because of the liver risk, it is generally not recommended for daily or long-term use, and periodic liver function testing may be wise.

About Alemtuzumab Injection (Chronic Lymphocytic Leukemia)

What Is Alemtuzumab Injection (Chronic Lymphocytic Leukemia) Used For?

Brand name: Campath

Alemtuzumab (brand name Lemtrada) is approved for adults with relapsing forms of multiple sclerosis (MS) — including relapsing-remitting MS and active secondary progressive MS. Because it carries serious risks, it is generally reserved for people who have already tried at least two other MS medications without adequate results.

It is not recommended for people with clinically isolated syndrome (CIS), a first episode of MS-like symptoms, due to its risk profile.
