The bottom line No known interaction

We found no known interaction between Procaine and Montelukast Sodium in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Procaine and Montelukast Sodium

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 Montelukast Sodium and Procaine 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 Montelukast Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Montelukast Sodium is filed under 2 classifications — cytochrome p450 2c9 (cyp2c9) substrates, oral drugs. Procaine has documented interactions with 5 drug classes — the most serious being digoxin (lanoxin) (major), skeletal muscle relaxants (major) and succinylcholine (major) — and none of Montelukast Sodium’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.

Keep it in perspective

What Procaine Itself Has Been Linked To

This is not an interaction — nothing below involves Montelukast Sodium. It is the side-effect record for Procaine on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Procaine, this list is the first place to look.

Everything above comes from the Natural Medicines adverse-effect record for Procaine — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Montelukast Sodium’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Montelukast Sodium column appears here.

Everything else you take

See Every Supplement That Interacts With Montelukast Sodium

This page covers Procaine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Montelukast Sodium page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Bacopa (moderate) and Berberine (moderate).

By severity: 1 major · 56 moderate · 24 minor.

From our pharmacist’s overview on the Montelukast Sodium page

“If you rely on montelukast (Singulair) for asthma or allergies, this list deserves genuine attention. The one major-rated concern is activated charcoal, which can soak up the medicine in your gut before it absorbs, leaving you with a weaker dose just when your airways need a steady one.”

About Procaine

What is Procaine?

  • Local anesthesia (medical/dental use)
  • Marketed 'anti-aging' supplements
  • General well-being and vitality claims
  • Mood and energy support (unproven)

Procaine is a synthetic local anesthetic (best known by the brand name Novocaine) used by doctors and dentists to numb tissue. It is not a true dietary supplement or herb, and the 'anti-aging' products built around it (such as GH3 or 'Gerovital') have weak evidence and real safety concerns. Talk to your pharmacist or doctor before using any product containing procaine.

Synthetic chemical compound (procaine hydrochloride) · Injectable solution (prescription), and in some products labeled 'procaine' or 'GH3' marketed as anti-aging supplements

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

Procaine: dosing

There is no established or recommended supplement dose for procaine. Because the benefits are unproven and the risks are real, many pharmacists would advise against using these products at all.

About Montelukast

What Is Montelukast Used For?

Brand name: Singulair

Montelukast is used for the long-term prevention and treatment of asthma in children and adults, and for preventing breathing problems triggered by exercise (exercise-induced bronchoconstriction). It is also used to relieve symptoms of seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis (year-round nasal allergies). The age ranges covered depend on the specific product form — tablets, chewable tablets, and oral granules are each approved for different age groups.

For allergic rhinitis, montelukast should be reserved for people who haven't responded well to other treatments, because its potential mental health risks may outweigh the benefits when nasal allergy symptoms are mild and other options work. It is not a rescue treatment for sudden asthma attacks — always keep a fast-acting inhaler on hand.

Most-Reported Side Effects for Montelukast Sodium

From FAERS, the FDA’s public side-effect reporting system (121,067 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Asthma 14,956 reports
Dyspnea 14,837 reports
Cough 9,067 reports
