What Rigix Oral Solution is
A liquid antihistamine for allergy symptoms, containing cetirizine, made by AGP Limited. We list it here for anyone looking for “Rigix syrup”. Rigix Oral Drops are a stronger liquid of the same medicine, given by the drop.
- Registered with DRAP under number 020308. (DRAP registry entry).
- Rigix Oral Drops: Registered with DRAP under number 105258. (DRAP registry entry).
- The 120 ml carton describes a cherry flavour. DRAP’s registration name for 020308 does not state a flavour; DRAP also registers a separate 60 ml strawberry-flavoured Rigix Oral Solution, which is not the one we sell.
- AGP publishes no leaflet for the liquids online. Its product pages for the solution and the drops give uses and ages; the rest of the facts here come from the UK and Swedish labels for cetirizine liquids of the same strengths, each named. Where AGP and those labels differ, the page shows both. Follow the directions on the pack.
- DRAP notifies no price for either: the price index has no entry. Our prices are the ones printed on the cartons. For adults, Rigix tablets contain the same medicine.
- We sell the oral solution without asking for a prescription. Before dispensing the drops, our pharmacist asks which form the doctor prescribed and the child’s age: the drops are ten times as strong as the solution, millilitre for millilitre.
What is in it
One active ingredient, from the label claims in DRAP’s registry.
| Product | Active ingredient | DRAP label claim | Strength |
|---|---|---|---|
| Rigix Oral Solution | Active ingredient: Cetirizine hydrochloride | DRAP label claim: “Each 5ml contains: Cetirizine hydrochloride 5mg” | Strength: 1 mg per ml |
| Rigix Oral Drops | Active ingredient: Cetirizine dihydrochloride | DRAP label claim: “Each 5ml contains: Cetirizine Dihydrochloride 50mg” | Strength: 10 mg per ml |
The drops are ten times as strong as the solution, millilitre for millilitre: never swap one for the other. Rigix’s inactive ingredients are not published. Comparable liquids contain sweeteners and preservatives (the UK solution lists sorbitol, propylene glycol and parabens), so check the bottle if your child must avoid any of these.
The salts are named inconsistently. DRAP’s label claims say hydrochloride for the solution and dihydrochloride for the drops (the solution’s own composition field in the registry says “Citrazine Dihydrochloride”). AGP’s product pages say the reverse: dihydrochloride for the solution, hydrochloride for the drops. The strengths agree: 1 mg per ml and 10 mg per ml.
What it is used for
Allergy symptoms. Neither label lists flu or colds. The UK label and AGP’s solution page name different uses for children aged 2 to 5.
| Label | Approved for |
|---|---|
| UK, oral solution 5 mg/5 ml | Adults and children aged 6 and over: hay fever, year-round allergic rhinitis and long-lasting hives (chronic idiopathic urticaria). Children aged 2 to 5: “seasonal rhinitis (hay fever)” only. |
| Sweden, oral drops 10 mg/ml | Adults and children aged 2 and over: nose and eye symptoms of hay fever and year-round allergic rhinitis, and long-lasting hives. |
| AGP (Pakistan), Rigix Oral Solution | Seasonal and year-round allergic rhinitis, and chronic idiopathic urticaria. Its doses for ages 2 to 5 are headed “for Chronic Urticaria”, and for 6 months to under 2 “for Perennial Allergic Rhinitis and Chronic Urticaria”. Not an approval by a regulator: the maker’s own page. |
| AGP (Pakistan), Rigix Oral Drops | Seasonal allergic rhinitis “with or without allergic conjunctivitis”, year-round allergic rhinitis, and “pruritus and other symptoms of urticaria of allergic origin”. The maker’s own page. |
For a child aged 2 to 5 with year-round symptoms or hives, ask a doctor first: the UK label approves the solution only for hay fever at that age, while AGP’s page names hives (chronic urticaria) for that age.
How to give it
How much and how often depend on the child’s age. Follow the pack, or ask our pharmacist.
- The drops, from the Swedish label for Zyrlex 10 mg/ml oral drops: “The drops should be poured in a spoon or diluted in water, and taken orally”; if diluted, “The diluted solution should be taken immediately.”
- Food: the UK label for cetirizine 5 mg/5 ml oral solution says “The extent of absorption of cetirizine is not reduced with food, although the rate of absorption is decreased.”
Check with a doctor or pharmacist first
Both labels give the same cautions.
- Warning: Kidney disease: the amount must be adjusted in moderate or severe kidney disease, and it must not be used when kidney function is very low (creatinine clearance below 10 ml/min).
- Epilepsy, or a risk of fits: both labels recommend caution.
- Difficulty passing urine, for example after a spinal cord injury or with an enlarged prostate: it may increase the risk of urine retention.
- An allergy to cetirizine, hydroxyzine or a related medicine: do not use it.
Drowsiness and alcohol
It can make children and adults sleepy. In children’s trials reported in the UK label for cetirizine 5 mg/5 ml oral solution, sleepiness was the most frequent side effect.
- The UK label: people who feel sleepy should not drive or operate machinery, and alcohol or other sedating medicines may add to the effect.
- The Swedish label: no important interaction with alcohol was shown at a blood alcohol level of 0.5 g/l, but it still recommends caution with alcohol.
Stopping after long-term use
Rarely, severe itching can start after stopping cetirizine taken daily for months or years. The FDA and DRAP warnings cover cetirizine taken by mouth (“oral allergy medicines”), in prescription and over-the-counter forms.
| Source | What it says |
|---|---|
| US FDA, 16 May 2025 | Requires a warning about rare but severe itching after stopping long-term use of oral cetirizine or levocetirizine. |
| DRAP Safety Alert No. 66, 9 February 2026 | “Safety Alert of Risk of severe itching after discontinuation of long-term use of Cetirizine and Levocetirizine”. |
If your child will take it for more than a few months, discuss it with a doctor. If severe itching starts after stopping, contact a healthcare professional.
Side effects in children
In placebo-controlled trials in children aged 6 months to 12 years, reported in the UK label for cetirizine 5 mg/5 ml oral solution, these happened in at least 1 in 100 children, slightly more often than with a placebo.
| Side effect | Cetirizine | Placebo |
|---|---|---|
| Sleepiness | Cetirizine: 1.8% | Placebo: 1.4% |
| Runny or blocked nose | Cetirizine: 1.4% | Placebo: 1.1% |
| Diarrhoea | Cetirizine: 1.0% | Placebo: 0.6% |
| Tiredness | Cetirizine: 1.0% | Placebo: 0.3% |
Never give more than the pack says. The UK label lists confusion, restlessness, marked sleepiness and difficulty passing urine among the effects reported after an overdose; if you think a child has had too much, contact a doctor at once.
Pregnancy and breastfeeding
For adults taking the liquid: both labels ask for caution.
- Pregnancy: the Swedish label says collected pregnancy data “do not suggest potential for maternal or foetal/embryonic toxicity above background rates”, but “Caution should nevertheless be exercised”; the UK label also advises caution.
- Breastfeeding: “Cetirizine passes into breast milk. A risk of side effects in breastfed infants cannot be excluded.” (both labels)
Checking your pack is genuine
DRAP’s alert below concerns a Rigix 10 mg tablet, not the liquids on this page. As of 16 October 2026, no DRAP alert names Rigix Oral Solution or Rigix Oral Drops.
- Check that the carton is sealed and that the batch number and expiry date on the carton match the bottle.
- The solution and the drops are different strengths: make sure the carton says the one you ordered.
DRAP Alert No. I/S/09-25-59, 10 September 2025: A spurious Rigix 10 mg tablet, recovered from an unauthorised seller. It concerns the tablet, not the liquids.
We buy only from authorised distributors, and check the batch and expiry on every item before it is packed.
Information as of 16 October 2026. DRAP publishes new alerts on dra.gov.pk.

Medicines and supplements can’t be returned once they have left our pharmacy.

- Anything that arrives expired or within a month of expiry we replace or refund, your choice, with no time limit.
Frequently asked questions
Is Rigix Syrup for flu?
No. Rigix Oral Solution contains cetirizine, an antihistamine for allergy symptoms. The UK and Swedish labels for cetirizine liquids approve it for hay fever, year-round allergic rhinitis and long-lasting hives; neither lists flu or colds.
What is cetirizine HCL Syrup used for?
Allergy symptoms. The UK label for cetirizine 5 mg/5 ml oral solution approves it for hay fever, year-round allergic rhinitis and long-lasting hives in adults and children aged 6 and over, and for hay fever only in children aged 2 to 5. It is not recommended under age 2. AGP’s own product page for Rigix gives doses from 6 months; we follow the UK label’s stricter position.
How to use Rigix drops?
Follow the directions on the pack: how much and how often depend on the child’s age. The Swedish label for cetirizine 10 mg/ml drops says the drops should be poured in a spoon or diluted in water and taken by mouth, and a diluted dose taken immediately. The drops are ten times as strong as the oral solution, so never swap one for the other.
Can I take cetirizine with food?
Yes. The UK label for cetirizine oral solution says food does not reduce how much is absorbed, although it is absorbed more slowly.

DRAP registration
- Rigix Oral Solution (020308), AGP Limited. DRAP’s registry shows: Reviewed, “Not Verified”.
- Rigix Oral Drops 10mg/ml (105258), AGP Limited. DRAP’s registry shows: Reviewed, “Not Verified”.
DRAP publishes no definition of this verification flag, so we can’t tell you what it means. We searched DRAP’s website for “Rigix” and “cetirizine” on 16 October 2026 and found one alert naming Rigix, about the 10 mg tablet, not these liquids (under “Checking your pack is genuine”), DRAP’s safety alert on itching after stopping cetirizine (above), and other cetirizine recall alerts that do not name Rigix. When we tested it, the search did not find a word that appears only inside an alert’s attached PDF, so an alert that names a product only in its PDF may not show up. DRAP describes its registered products index as a provisional list that “cannot be used as a reference for any purpose”. Checked against the registry on .
