Why is this medication prescribed?

Aquatab C, containing the active ingredient phenylephrine, is a medication typically used as a decongestant. Phenylephrine works by constricting blood vessels in the nasal passages, reducing swelling and congestion.

Aquatab C (Phenylephrine) is prescribed for the following purposes:

• Relief of Nasal Congestion: It is often used to alleviate nasal congestion caused by colds, allergies, or hay fever.
• Sinus Congestion: It can help relieve sinus pressure and congestion.
• Eustachian Tube Congestion: It may be used to alleviate pressure and congestion in the eustachian tubes (connecting the throat to the middle ear).

How should this medicine be used?

Aquatab C is typically used for disinfecting drinking water, making it safe for consumption. The usage instructions can vary based on the specific product and concentration of the active ingredient. However, here are general guidelines:

• Check the Tablet Size and Strength: Aquatab C tablets come in different sizes and strengths, which determine how much water they can treat. Be sure to read the packaging or instructions to know how much water a single tablet can purify.
• Prepare the Water: Collect the water to be treated in a clean container.
• Add the Tablet: Drop the appropriate number of tablets into the water. Typically, one tablet is used per liter of water, but this can vary based on the strength of the tablet. If you are using a larger container, adjust the number of tablets accordingly.
• Mix Well: Stir or shake the water container to help the tablet dissolve and mix thoroughly.
• Wait for the Disinfection Time: Allow the water to sit for the time specified in the instructions, usually around 30 minutes. This time allows the tablet to kill harmful microorganisms in the water.
• Check the Water: After the waiting period, the water should be clear and have a slight chlorine odor, indicating it has been disinfected.
• Storage and Consumption: Use the treated water within 24 hours for drinking or cooking. Store it in a clean, covered container.
• Additional Considerations: If the water is very cloudy or has a lot of suspended particles, it’s advisable to filter it through a cloth or let it settle before adding the tablet. Follow any additional instructions provided on the product packaging, as they may include important details specific to the particular type of Aquatab C you are using.

Always read and follow the specific instructions provided with the Aquatab C product you have, as different formulations may have unique requirements.

Other uses for this medicine

What special precautions should I follow?

Special Precautions for Using Aquatab C:

• Hypertension (High Blood Pressure): Phenylephrine can raise blood pressure, so it should be used cautiously or avoided in individuals with hypertension.

• Glaucoma: Phenylephrine can increase eye pressure, so it should be avoided in patients with narrow-angle glaucoma.
• MAO Inhibitors: Do not use Aquatab C if you have taken an MAO inhibitor within the last 14 days, as it can cause dangerous interactions.
• Other Decongestants: Avoid using other medications containing decongestants or stimulants, as this can increase the risk of side effects.
• Pregnancy and Breastfeeding: Consult a healthcare provider before using Aquatab C if you are pregnant or breastfeeding. Phenylephrine may not be safe for use during pregnancy, especially in the first trimester.
• Allergic Reactions: Avoid this medication if you have had an allergic reaction to phenylephrine or similar medications.
• Age Considerations: Use in children under 12 years of age should only be under medical supervision. The dosage may need to be adjusted, or an alternative medication may be recommended.
• Driving and Operating Machinery: Phenylephrine can cause dizziness or restlessness. Avoid driving or operating heavy machinery until you know how the medication affects you.
• Overuse and Dependence: Prolonged use or overuse can lead to rebound congestion, where nasal passages become more congested. Limit use to a short duration as recommended by a healthcare provider.

Always follow your healthcare provider’s advice and the product’s instructions for safe and effective use.

What special dietary instructions should I follow?

There are no specific dietary restrictions associated with Aquatab C. However, it is generally advisable to:

• Stay Hydrated: Drink plenty of fluids, as this can help thin mucus and relieve congestion.
• Limit Caffeine: Caffeine may increase the stimulant effects of phenylephrine, such as nervousness or increased heart rate. Limiting caffeine intake (from coffee, tea, soda, etc.) may be beneficial.

What should I do if I forget a dose?

• Take It When You Remember: If it’s close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule.
• Do Not Double Up: Do not take two doses at once or extra doses to make up for the missed one. Taking too much phenylephrine can increase the risk of side effects.
